Part A
ans all ques..

1. What do you mean by dynamic binding? How is it useful in OOP?
2. Distinguish ranging from the subsequent terms Data abstraction and Data encapsulation.
3. When do we declare a member of a class static?
4. How do we invoke a constructor function?
5. What is function overloading?
6. discuss syntax of binary operator overloading? How many arguments are needed in the definition of an overloaded binary operator?
7. What do you mean by multiple and multilevel inheritance?
8. What is an abstract class?
9. What does this pointer point to?
10. elaborate new and delete?
(10 X four = 40 marks)

Part B
11. define the features that characterize object oriented programming.
Or
12. elaborate the guidelines that need to be followed for deciding whether to make the member function inline or not?

13. With an example discuss how an object may be used as a function argument.
Or
14. elaborate constructors and destructors? discuss how they differ from normal functions? Illustrate with an example.

15. Write a C++ program to overload arithmetic operators for manipulating vectors.
Or
16. elaborate friend functions and friend classes? Write a normal function which adds objects of the complex number class. Declare this normal function as friend of Complex class.

17. With an example discuss the concept of base class, derived class and visibility modes.
Or
18. define the different approaches by which we can detect the end-of-file condition successfully.

19. Write a program to illustrate the use of pointers to derived class.
Or
20. Distinguish ranging from Virtual function and Pure Virtual function.
