Question

Design a base class Shape with virtual functions

void draw(GraphicWindow& win) const;
void move(double dx, double dy);

The Circle, Line, and Message classes of Chapter 2 are not derived from the Shape
class. Supply three adapter classes CircleShape, LineShape, and MessageShape. Supply
a test program that populates a vector<Shape*> with adapted objects, and demon-
states the draw and move functions.

#include "ccc_win.h"

int ccc_win_main()

{  

   Point p(1, 3);

   cwin << p << Circle(p, 2.5);

   return 0;

}

#include "ccc_shap.h"

#if defined(_MSC_VER)

   #define CCC_MSW

#endif

#if defined(_WINDOWS_) || defined (_Windows) || defined(WINVER) || defined(__WIN32__)

   #define CCC_MSW

#endif

#if defined(__GNUC__) && !defined(CCC_MSW)

   #define CCC_X11

#endif

#if defined(CCC_ASC)

#include "ccc_asc.h"

#elif defined(CCC_WXW)

#include "ccc_wxw.h"

#elif defined(CCC_X11)

#include "ccc_x11.h"

#elif defined(CCC_MSW)

#include "ccc_msw.h"

#else

#include "ccc_asc.h"

#endif
