SECTION-B
What is the use of default & copy constructors? Is a constructor mandatory for a Class? Explain by giving examples in each case.
Explain how base class member functions can be invoked in a derived class if the derived class also has a member function with the same name.
What is a virtual function? Explain its usage with example.
Write a program to exchange values between two classes using the concept of friend functions.
SECTION-C
Write a class to represent a vector (a series of float values). Include member functions to perform the following tasks :
a) To create the vector
c) To multiply by a scalar value
d) To display the vector in the form (10, 20, 30,...)
e) Write a program to test your class
Write a program to overload the plus operator to add two complex numbers.
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any page of Answer Sheet will lead to UMC against the Student.
