Programming Language: C++

With the Abstract Class Shape, Make the Implementation by heritage of the derived classes Circle, Rectangle and Square. Also add them in main.cpp.

Circle and Rectangle must inherit from Shape, and Square must inherit from Rectangle.

----------------------------------------- Shape Functions: getArea(): double getPerimeter(): double ---------------------------------------

Circle's data members: -radius: double Circle Functions: Circle() Circle(aRadius: double) setRadius(r: double):void

-------------------------------------------

Rectangle's data members: -width, height: double

Rectangle Functions: Rectangle() Rectangle(w: double, h: double) setWidth(w: double): void

setHeight(h: double): void

-----------------------------------------

Square Functions: Square() Square(s: double) setSide(s: double): void

-----------------------------------

Codes for Shape.h:

#ifndef SHAPE_H #define SHAPE_H

Codes for shape: class Shape { public: double getArea() const = 0; double getPerimeter() const = 0; };

#endif // SHAPE_H -----------------------------------------

Codes for Shape.cpp

#include "Shape.h"

double Shape::getArea() const { return area; }

double Shape::getPerimeter() const { return perimeter; } ----------------------------------------------------

Codes for Rectangle.h

#include "Shape.h"

#ifndef RECTANGLE_H #define RECTANGLE_H

class Rectangle : public Shape { protected: double width; double height; public: void setWidth(double w); void setHeight(double h); };

#endif // RECTANGLE_H -------------------------------------------------

Codes for Rectangle.cpp

#include "Rectangle.h"

void Rectangle::setWidth(double w) { }

void Rectangle::setHeight(double h) { } --------------------------------------------------------------
