1. Write a program to illustrate the manipulation using pointer to objects and pointer to member of a

2. Explain with suitable program to demonstrate how a function can be overloaded in different
ways. [16]
3. Illustrate the use of friend function with example program [16]
4. Write a program to find maximum between two numbers using friend class. [16]
5. (i) Explain object oriented paradigm with all its essential elements. [12]
    (ii) state the merits and demerits of OOP. [4]
6. (i) Explain the usage of friend keyword with an example program. [8]
    (ii) Write a C++ program to illustrate static function. [8]
7. What are friend functions and friend classes? Write a normal function which adds objects of the complex
