TwoDimensionalShape:

            Member functions: pure virtual function for GetArea

Circle:     Private data member: radius

            Member function: constructor, GetArea

Square:     Private data member: length

            Member function: constructor, GetArea

Triangle:   Private data members: base and height

            Member function: constructor, GetArea

Each TwoDimensionalShape should cotain a virtual function GetArea to calculate the area of the shape. Use the following main function to test your classes.

int main()

{

Circle c(10);

Square s(10);

Triangle t(10,5);

c.GetArea();                                  // will display
