(b) Write an interactive program which processes date of birth using structure.

(c) Explain following with their syntax :

(i) Pointer to structure

(ii) Array of structure.

OR

1. (a) What is difference between structured programming and object oriented programming ?

(b) What is object oriented paradigm ? Explain the various features of object oriented paradigm ?

What is class and object ? Describe the syntax for class and object specification with example. How does it accomplish data hiding ? Give an example.

UNIT – II

2. (a) What is constructor ? How many types of constructors are in C++ ? Describe with the help of a suitable example.

(b) Explain the concept of inline function in C++. How it is beneficial in programming ?

OR

(a) Explain mechanism of accessing a private data member of the class from a non member function and justify it with a program in C++ to swap private data members of two classes.

(b) Explain static data members and static member functions with suitable example.

UNIT – III

(a) What is operator overloading ? State the rules to be followed for overloading operators.

(b) Write a program to overload unary (++) operator ? What are the limitations of overloading unary increment / decrement operator ? How are they overcome ?

OR

(a) What is type conversion in C++ ? How it is achieved in user defined data types?

(b) Write a C++ program to make a class named “string”, which uses concept of operator overloading to concatenate two strings by (+) operator.

UNIT – IV

 

4. (a) What is inheritance ? What are the different forms of inheritance supported by C++ ? Explain each with suitable example.

(b) What is visibility mode ? What are different inheritance visibility modes supported by C++ ?

OR

(a)  What is pure virtual function ? What are the implications of making function pure virtual function ?

(b) What are abstract classes ? Explain the role of abstract class while building the class hierarchy.

UNIT – V

5. (a) Explain the multiple inheritance with example.

(b) What is virtual base class ? When do we make a class virtual ? Explain with example.

OR

(a)  What is generic programming? How is it implemented in C++ ? Write a program to implement swapping using templates.

(b) Explain try, throw and catch constructs used in C++ with their syntax.
