Question 1

codingan Polymorphism?

Answer 1

#include 
using namespace std;

class CPolygon
{
	protected:
		int width, height;
	public:
		void setup (int first, int second)
		{
			width= first;
			height= second;
		}
};

class CRectangle: public CPolygon
{
	public:
		int area()
		{
			return (width * height);
		}
};

class CTriangle: public CPolygon
{
	public:
		int area()
		{
			return (width * height / 2);
		}
}; 

int main ()
{
CRectangle rectangle;
CTriangle triangle;

CPolygon * ptr_polygon1 = &rectangle;
CPolygon * ptr_polygon2 = ▵

ptr_polygon1->setup(2,2);
ptr_polygon2->setup(2,2);

cout << rectangle.area () << endl;
cout << triangle.area () << endl;

return 0; }
