C++ Virtual Function - Exercise

Adding a virtual function

Objective: Add a virtual function to the shape class that returns the name of a shape as a char* value.

Background:

Here is the Shape class hierarchy for reference:
In Java, all classes becuse with a capital letter.

class Shape {
public:
 virtual double  area() const { return 0; }
 //virtual double area is default behavior 
 protected:
  double  x, y;
};

class rectangle : public shape {
 public:
  double  area() const { 
   return (height * width); 
  } 
 private:
  double  height, width;
};

class circle : public shape {
public:
 double  area() const{ 
  return (PI * radius * radius);
 }
private:
 double   radius;
};

This code is also available in a file named shape.cpp, which can be found in the compressed course download file available on the Resources page.
