b) What is type conversion?
2
c) What is inheritance? List out the types of Inheritance. 3
6. a) What is Multiple Inheritance? Write a c++ program to illustrate
Multiple Inheritance
10
b) Explain the concept of Nesting of Classes. 5
7. a) Explain the use of this pointer. 5
b) . Create a base class called 'SHAPE'
having

- two data members of type double
- member function get-data( ) to initialize base class data members
- Pure virtual member function display-area ( ) to compute and display the
area of the geometrical object.
Derive two specific classes 'TRIANGLE' and 'RECTANGLE' from
the base class. Using these three classes design a program that will accept
dimension of a triangle / rectangle interactively and display the area.
