Our Body has a Color

#ifndef __BODY_H__

#define __BODY_H__

#include "Color.h"

class body {

public:

// the constructors for body

body();

body(Color *c);

// the destuctor

~body();

// the member functions we already know

virtual float GetVolume() =0;

virtual float GetSurface() =0;

// two more functions which deal with the color

virtual void setColor (Color *c);

virtual Color * getColor();

protected:

Color * color;

int our_color;

};

#endif /* __BODY_H__ */

#include "body.h"

// the standard constructor first

body::body()

{

// since we didn't specify a color...

color = new Color(0.,0.,0.);

our_color = 1;

}

// the constructor setting a color

body::body(Color *c)

{

// we just grab the pointer to the color provided.

color = c;

our_color = 0; // we did not make the color class.

}

// and the destructor

body::~body()

{

// if we made the color object, we must delete it here.

if (our_color) delete color;

}

// now the color-handling

void body::setColor (Color *c)

{

if (our_color) delete color;

our_color = 0;

color = c;

}

Color * body::getColor()

{

return color;

}

Warning: this class design works but is flawed. We will later improve the design.
