     b) . Create a base class called 'SHAPE' having                                                                             10

-       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.

the base class.  Using these three classes design a program that will accept

dimension of a triangle / rectangle interactively and display the area.
