C++ typeid operator - Exercise

Using typeid

Objective: Use the typeid operator instead of the virtual function you wrote that returns the name of a shape as a char* value.

Instructions

Write a main() function that uses the typeid operator to return the name of a shape as a char* value. Print out the name of each shape subtype defined for the shape class. Your system will need to have type_info.h to complete this exercise.
Here is the shape class hierarchy for reference:

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.
