Answer ONE Question from each Unit

All Questions Carry Equal Marks

All parts of the question must be answered in one place only

UNIT - I

1. (a) Discuss the concept of implicit type conversion with a suitable example. [7M]
   (b) Write a C program that calculates and prints the average of entered integers. Assume the user will enter control-d to end the input. [7M]

   Sample Run:
   Enter an integer (control-d to end): 23
   Enter an integer (control-d to end): 123
   Enter an integer (control-d to end): 45
   Enter an integer (control-d to end): 987

   Enter an integer (control-d to end): 87
   Enter an integer (control-d to end): 098
   Enter an integer (control-d to end):
   The average is : 227.17
2. (a) A palindrome is a number or a text phrase that reads the same backwards as forwards. Write a C program that reads in a five-digit integer and determines whether or not it is a palindrome. [7M]

   Hint: Use the division and modulus operators to separate the number into its individual digits.
   Sample Run 1:
   Enter a five-digit number: 12345
   12345 is not a palindrome
   Sample Run 2:

   Enter a five-digit number: 12321
   12321 is a palindrome
   (b) Discuss the concept of identifiers and data-types in C. [7M]

UNIT II

1. (a) With a suitable example, discuss the following categories of user defined functions in C [10M]
   1. functions with arguments and return values
   2. function with no argument and return type

   (b) Explain briefly how do you pass a 2D array as a parameter in C? [4M]
2. (a) The factorial of a integer N, denoted by N! is the product of all positive integers less than or equal to N. Factorial does not exist for negative numbers and factorial of 0 is 1. Write a recursive routine to compute factorial of a number. Write a test driver for the same. [8M]
   (b) What is an array? How is an array declared and initialized? [6M]

UNIT - III

1. (a) Bring out the significance of pointers to void with a suitable example. [8M]
   (b) In C, a string can be referred either using a character pointer or as a character array. Explain it with examples. [6M]

2. (a) Explain briefly pointer arithmetic in C with suitable examples. [6M]
   (b) What are the unformatted string input and output functions available in C? Is the input function safe? If yes, why and If no, Justify? [8M]

UNIT - IV

1. (a) With a suitable example explain the concept of typedef. [6M]
   (b) A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, satisfying the equation i² = −1. Write a C Program to add two complex numbers by passing structure to a function. [8M]
2. (a) Write a C program using nested structures to read 3 employees details with the following fields; emp-id, name, designation, address, basic, da, hra and calculate gross salary of each employee. [9M]
   

   --- Content provided by FirstRanker.com ---

   (Hint : gross salary = basic + da + hra).
   (b) Bring out the advantage of using Bit Fields in C with a suitable example. [5M]

UNIT - V

1. (a) Why is fseek() preferred over rewind() in C? [6M]
   (b) Write a C Program to Copy Contents of one file to another file. [8M]
2. (a) Discuss how reading and writing w.r.t binary file done in C. [8M]
