Ex. No: 1a IMPLEMENTATION OF STACK ADT
Date:
Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.
6. Close the program
Sample output :
Enter the size of STACK[MAX=100]:10

Date:
Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.
6. Close the program

2. Write function for all the basic operations of stack - Enqueue(), Dequeue() and Display().
3. By using Switch case, select Enqueue() operation to insert element in to the rear/back end
of the queue.
Check whether queue is FULL. (rear == SIZE-1)
If it is FULL, then display "Queue is FULL!!! Insertion is not possible!!!" and terminate
the function.
If it is NOT FULL, then increment rear value by one (rear++) and set queue[rear] =
value
4. Similarly, by using Switch case, select Dequeue() function is used to remove the element
from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define an integer variable 'i' and set 'i = front+1'.
Step 3: Display 'queue[i]' value and increment 'i' value by one (i++). Repeat the same
until 'i' value is equal to rear (i <= rear)

Ex. No: 1a IMPLEMENTATION OF STACK ADT
Date:
Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

3. By using Switch case, select Enqueue() operation to insert element in to the rear/back end
of the queue.
Check whether queue is FULL. (rear == SIZE-1)
If it is FULL, then display "Queue is FULL!!! Insertion is not possible!!!" and terminate
the function.
If it is NOT FULL, then increment rear value by one (rear++) and set queue[rear] =
value
4. Similarly, by using Switch case, select Dequeue() function is used to remove the element
from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define an integer variable 'i' and set 'i = front+1'.
Step 3: Display 'queue[i]' value and increment 'i' value by one (i++). Repeat the same
until 'i' value is equal to rear (i <= rear)

Date:
Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).

from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define an integer variable 'i' and set 'i = front+1'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

Aim:
To write a C program to implement List ADT by using linked list
Algorithm:
1. Create the header file Llist.h header file and we are include there header file into the main
function program by through #include< Llist.h >
2. Write function for all the basic operations of list - create(), insert(), deletion(), search(),
display().
3. By using Switch case, select create() operation to create the list.
List Will be in the form: A 1, A 2, A 3, .... A n
First Element of the List: A 1
Last Element of the List: A n
ith Element of the List: A i ,
Position of Element A i : i , Position ranges from 0 to N
Size of the List: N
Empty List: If Size of the list is Zero (i.e N=0), it is Empty List.
Precedes and Succeeds: For any list except empty list, we say that Ai+1 follows
(or succeeds) A i (i< and that A i-1 precedes Ai (i>1)
4. Similarly, by using Switch case, select insert() operation to insert element in the list.
Insert x at position p in list L
If p = END(L), insert x at the end
If L does not have position p, result is undefined
5. Similarly, by using Switch case, select delete() function is used to remove the element
from the list.
delete element at position p in L
undefined if p = END(L) or does not exist
6. Similarly, by using Switch case, select search() function is used to retrieve the required
element from the list if it is available.
returns element at position p on L
undefined if p does not exist or p = END(L)
7. Similarly, by using Switch case, select display() operation to display all element of the list
print the elements of L in order of occurrence

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.

To write a C Program to implement different searching techniques Linear and Binary
search.
Algorithm:
Linear Search:
1. Read the search element from the user
2. Compare, the search element with the first element in the list.
3. If both are matching, then display "Given element found!!!" and terminate the function
4. If both are not matching, then compare search element with the next element in the list.
5. Repeat steps 3 and 4 until the search element is compared with the last element in the list.
6. If the last element in the list is also doesn't match, then display "Element not found!!!" and
terminate the function.
Binary search is implemented using following steps...
1. Read the search element from the user
2. Find the middle element in the sorted list
3. Compare, the search element with the middle element in the sorted list.
4. If both are matching, then display "Given element found!!!" and terminate the
function
5. If both are not matching, then check whether the search element is smaller or
larger than middle element.
6. If the search element is smaller than middle element, then repeat steps 2, 3, 4 and
5 for the left sublist of the middle element.
7. If the search element is larger than middle element, then repeat steps 2, 3, 4 and 5
for the right sublist of the middle element.

to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

2. If powers of the two terms are equal
then if the terms do not cancel
then insert the sum of the terms into the sum Polynomial
Advance p
Advance q
Else if the power of the first polynomial> power of second
Then insert the term from first polynomial into sum polynomial
Advance p
Else insert the term from second polynomial into sum polynomial
Advance q
3. copy the remaining terms from the non empty polynomial into the sum polynomial.
The third step of the algorithm is to be processed till the end of the polynomials has not been
reached.

Check whether queue is Empty (rear == NULL)
If it is Empty then, set front = newNode and rear = newNode.
If it is Not Empty then, set rear next = newNode and rear = newNode.
6. dequeue() - Deleting an Element from queue
Check whether queue is Empty (front == NULL).
If it is Empty, then display "Queue is Empty!!! Deletion is not possible!!!" and terminate
from the function
If it is Not Empty then, define a Node pointer 'temp' and set it to 'front'.
Then set 'front = front next' and delete 'temp' (free(temp)).
7. display() - Displaying queue of elements
Check whether queue is Empty (front == NULL).
If it is Empty then, display 'Queue is Empty!!!' and terminate the function.
If it is Not Empty then, define a Node pointer 'temp' and initialize with front.
Display 'temp data --->' and move it to the next node. Repeat the same until 'temp'
reaches to 'rear' (temp next != NULL).
Finally! Display 'temp data ---> NULL'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.

(or succeeds) A i (i< and that A i-1 precedes Ai (i>1)
4. Similarly, by using Switch case, select insert() operation to insert element in the list.
Insert x at position p in list L
If p = END(L), insert x at the end
If L does not have position p, result is undefined
5. Similarly, by using Switch case, select delete() function is used to remove the element
from the list.
delete element at position p in L
undefined if p = END(L) or does not exist
6. Similarly, by using Switch case, select search() function is used to retrieve the required
element from the list if it is available.
returns element at position p on L
undefined if p does not exist or p = END(L)

Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

3. By using Switch case, select Enqueue() operation to insert element in to the rear/back end
of the queue.
Check whether queue is FULL. (rear == SIZE-1)
If it is FULL, then display "Queue is FULL!!! Insertion is not possible!!!" and terminate
the function.
If it is NOT FULL, then increment rear value by one (rear++) and set queue[rear] =
value
4. Similarly, by using Switch case, select Dequeue() function is used to remove the element
from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define an integer variable 'i' and set 'i = front+1'.
Step 3: Display 'queue[i]' value and increment 'i' value by one (i++). Repeat the same

1. Create an array[ ] with MAX size as your wish.
2. Write function for all the basic operations of list - create(), insert(), deletion(), search(),
display().
3. By using Switch case, select create() operation to create the list.
List Will be in the form: A 1, A 2, A 3, .... A n
First Element of the List: A 1
Last Element of the List: A n
ith Element of the List: A i ,
Position of Element A i : i , Position ranges from 0 to N
Size of the List: N
Empty List: If Size of the list is Zero (i.e N=0), it is Empty List.
Precedes and Succeeds: For any list except empty list, we say that Ai+1 follows
(or succeeds) A i (i< and that A i-1 precedes Ai (i>1)
4. Similarly, by using Switch case, select insert() operation to insert element in the list.
Insert x at position p in list L
If p = END(L), insert x at the end
If L does not have position p, result is undefined
5. Similarly, by using Switch case, select delete() function is used to remove the element
from the list.
delete element at position p in L
undefined if p = END(L) or does not exist
6. Similarly, by using Switch case, select search() function is used to retrieve the required
element from the list if it is available.
returns element at position p on L
undefined if p does not exist or p = END(L)
7. Similarly, by using Switch case, select display() operation to display all element of the list
print the elements of L in order of occurrence
8. Close the program

Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.

2. Compare, the search element with the first element in the list.
3. If both are matching, then display "Given element found!!!" and terminate the function
4. If both are not matching, then compare search element with the next element in the list.
5. Repeat steps 3 and 4 until the search element is compared with the last element in the list.
6. If the last element in the list is also doesn't match, then display "Element not found!!!" and
terminate the function.
Binary search is implemented using following steps...
1. Read the search element from the user
2. Find the middle element in the sorted list
3. Compare, the search element with the middle element in the sorted list.
4. If both are matching, then display "Given element found!!!" and terminate the
function
5. If both are not matching, then check whether the search element is smaller or
larger than middle element.
6. If the search element is smaller than middle element, then repeat steps 2, 3, 4 and
5 for the left sublist of the middle element.
7. If the search element is larger than middle element, then repeat steps 2, 3, 4 and 5

Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.

of the queue.
Check whether queue is FULL. (rear == SIZE-1)
If it is FULL, then display "Queue is FULL!!! Insertion is not possible!!!" and terminate
the function.
If it is NOT FULL, then increment rear value by one (rear++) and set queue[rear] =
value
4. Similarly, by using Switch case, select Dequeue() function is used to remove the element
from the front end of the queue.
Check whether queue is EMPTY. (front == rear)
If it is EMPTY, then display "Queue is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then increment the front value by one (front ++). Then
display queue[front] as deleted element. Then check whether both front and rear are
equal (front == rear), if it TRUE, then set both front and rear to '-1' (front = rear = -1).
5. Similarly, by using Switch case, select display() operation to display all element of the
queue.
Step 1: Check whether queue is EMPTY. (front == rear)
Step 2: If it is EMPTY, then display "Queue is EMPTY!!!" and terminate the function.

function program by through #include< Llist.h >
2. Write function for all the basic operations of list - create(), insert(), deletion(), search(),
display().
3. By using Switch case, select create() operation to create the list.
List Will be in the form: A 1, A 2, A 3, .... A n
First Element of the List: A 1
Last Element of the List: A n
ith Element of the List: A i ,
Position of Element A i : i , Position ranges from 0 to N

Aim: To write a C program to implement Stack ADT by using arrays
Algorithm:
1. Create a Stack[ ] with MAX size as your wish.
2. Write function for all the basic operations of stack - PUSH(), POP() and DISPLAY().
3. By using Switch case, select push() operation to insert element in the stack.
Step 1: Check whether stack is FULL. (top == SIZE-1)
Step 2: If it is FULL, then display "Stack is FULL!!! Insertion is not possible!!!" and
terminate the function.
Step 3: If it is NOT FULL, then increment top value by one (top++) and set stack[top]
to value (stack[top] = value).
4. Similarly, By using Switch case, select pop() operation to delete element from the stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!! Deletion is not possible!!!" and
terminate the function.
Step 3: If it is NOT EMPTY, then delete stack[top] and decrement top value by one
(top--).
5. Similarly, By using Switch case, select display() operation to display all element from the
stack.
Step 1: Check whether stack is EMPTY. (top == -1)
Step 2: If it is EMPTY, then display "Stack is EMPTY!!!" and terminate the function.
Step 3: If it is NOT EMPTY, then define a variable 'i' and initialize with top. Display
stack[i] value and decrement i value by one (i--).
Step 3: Repeat above step until i value becomes '0'.
