C++

Consider a graphics system that has classes for various figures, say rectangles squares, triangles, circles, and so on. For example, a rectangle might have data members height, width, and center point, while a square and circle might have only a center point and an edge length or radius, respectively. In a well-designed system these would be derived from a common class, Figure. It is your job to implement this system First, implement the base class Figure. Then, implement two classes that are derived from Figure - Rectangle and Triangle. Each class should have stubs for the member functions erase) and draw). Each of these member functions outputs a message telling what function has been called and what the class of the calling object is. Since these are just stubs, they should do nothing more than output the message Also implement the member function center). Typically, center) would call erase and draw to erase and redraw the figure at the center. However, since our functions are only stubs, center) will simply print a message saying that center has been called from the respective class. It will then call erase) and drawO, which will each print out their own messags You should implement the base class functions as virtual functions. Finally, test your program in main() by creating a Triangle obiect and a Rectangle obiect and calling draw), erase), and center on each object SAMPLE RUN #0: . /Figures Interactive Session Hide Invisibles Triangle.object.called draw-function. .. .
