Part a) Create a base class called shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add to the base class, a member function get_data() to initialize base class data members and another member function display_area() to compute and display the area of figures. Make display_area() as a virtual function and redefine this function in the derived classes to suit their requirements. Using these three classes, design a program that will accept dimensions of a triangle or a rectangle interactively, and display the area.

Q1.
Part a) Create a base class called shape. Use this class to store two double type values
that could be used to compute the area of figures. Derive two specific classes called
triangle and rectangle from the base shape. Add to the base class, a member function
get_data() to initialize base class data members and another member function
display_area() to compute and display the area of figures. Make display_area() as a virtual
function and redefine this function in the derived classes to suit their requirements.
Using these three classes, design a program that will accept dimensions of a triangle or a
rectangle interactively, and display the area.
Part b) Overload the +' operator in triangle and rectangle classes. The overload function
should add the values of (sides of) two triangles (and similarly the sides of two rectangles)
and make a bigger triangle (and bigger rectangle) and return the area of big triangle(and
big rectangle).
