/* The class Rectangle inherits from the abstract class Shape,
   providing definitions for the virtual members of the Shape class. 

The data attributes of the Rectangle class are declared as protected:
(1) client programs that use Rectangle objects have no access to
    the data attributes;
(2) classes that inherit from Rectangle have access to the data members.

We override the virtual members of the abstract class shape
and provide two constructors via overloading. */
