Inheritance and Polymorphism

[salomonthesav]

I need help writing the formulas in my implementations. I also need help instantiating and populating random Circle and Rectangle objects into an array of “Shape pointer” type, making the array a size of 5.

  #include <iostream>
#include <string>
#include "Classes.h"
using namespace std;

int main()
{
	Shape* ptr1[5];
	/*ptr1[0] = new Circle();
	ptr1[1] = new Circle();
	ptr1[2] = new Circle();
	ptr1[3] = new Rectangle();
	ptr1[4] = new Rectangle();*/

	for (int i = 0; i < 5; i++)
	{
		cout << "-------" << endl;
		ptr1[i]->getArea();
	}
	return 0;
}





#include <string>
#include <iostream>
using namespace std;

//Shape
class Shape
{
public:
	virtual void getArea() const = 0;
};



//Circle
class Circle : public Shape
{
public:
	void getArea() const;
	Circle();
	Circle(double);
protected:
	double m_radius;
};



//Rectangle
class Rectangle : public Shape
{
public:
	void getArea() const;
	Rectangle();
	Rectangle(double, double);
protected:
	double m_height;
	double m_width;
};





#include <string>
#include <iostream>
#include "Classes.h"
using namespace std;


void Shape::getArea() const
{
	cout << "Area: " << endl;
}



Circle::Circle() :Shape()
{
	m_radius = 1;
}
Circle::Circle(double p_radius) :Shape()
{
	m_radius = p_radius;
}
void Circle::getArea() const
{
	Shape::getArea();
	cout << "Radius: " << m_radius << endl;
}



Rectangle::Rectangle() :Shape()
{
	m_height = 1;
	m_width = 1;
}
Rectangle::Rectangle(double p_height, double p_width) :Shape()
{
	m_height = p_height;
	m_width = p_width;
}
void Rectangle::getArea() const
{
	Shape::getArea();
	cout << "Height: " << m_height << endl;
	cout << "Width: " << m_width << endl;
}
