The Rectangleclass, demonstrated in Listing 10.1, has two DrawShape()functions.
One, which takes no parameters, draws the rectangle based on the class’s current values.
The other takes two values, width and length, and draws the rectangle based on those
values, ignoring the current class values.LISTING10.1 Overloading Member Functions
