Now we see it at work...

#include "cube.h"

#include "cylinder.h"

#include "iostream.h"

#include "Color.h"

main()

{

Color *yellow = new Color( 1.0, 1.0, 0.0 ); // yellow

Color *green = new Color( 0.0, 1.0, 0.0 ); // green

body *c1 = new cylinder (1.,2.); // default-colored cylinder

body *c2 = new cylinder (1.,2.,*green); // green cylinder

body *c3 = new cube (1.,*yellow); // yellow cube

cout << *c1 << endl;

cout << *c2 << endl;

cout << *c3 << endl;

}

$ main

cylinder of radius 1 height 2 Color ( 0, 0, 0 )

cylinder of radius 1 height 2 Color ( 0, 1, 0 )

cube of length 1 Color ( 1, 1, 0 )

Here we had ‘cylinder” and “cube” before

That’s it! The fully functional, fully by-the-rules body class and its children.
