UNIT – III

1. Write brief on the following:

a) Early and late binding

b) Virtual functions

2. Create a base class called figure and store two double type values

to compute the area of figures. Derive two classes called triangle

and rectangle from this base class. Base class should contain

get_data() to initialize date members and display_area() to compute

the area of figures. Make display_area() as virtual and redefine this

in derived this in derived class to suit their requirements. Include

these classes in a program to accept dimension of a triangle or a

rectangle interactively and display the area.

3. What is pure virtual function? Write a program to demonstrate it.

4. What is virtual function what are the properties of virtual function?

How will you achieve run time polymorphism using virtual

function?

5. Explain the term virtual base class?

6. What are the characteristics and the rules that need to be followed

with friend function?
