Answer to Question #284945 in C++ for Shayan

Question

Create a class Shape and two additional classes (each derived from Shape) named Rectangle and Triangle. The member attributes and functions for each class are given below:

Shape:

private:

int width;

int height;

public:

virtual int getArea();

Rectangle:

public:

virtual int getArea();

Triangle:

public:

virtual int getArea();

Driver Program:

Rectangle r1(3,2);

Triangle t1(3,2);

Shape *s1 = &r1;

s1->getArea();

Shape *s2 = &t1;

s2->getArea();

Answer 1

class Shape
{
	public:
	int width;
	int height;
	void getdimension(int w, int h)
	{
		width = w;
		height = h;
	}
};


class Rectangle:public Shape
{
	public:
	void getArea(void)
	{
		int Area;
		Area = width*height;
		cout<<"\n\tArea of Rectangle = "<<Area;
	}
};


class Triangle:public Shape
{
	public:
	void getArea()
	{
		int Area;
		Area = width*height/2;
		cout<<"\n\tArea of Triangle = "<<Area;
	}
	
};


//Driver Program:
int main()
{
	Rectangle r1;
	Triangle t1;
	
	r1.getdimension(3,2);
	t1.getdimension(3,2);
	
	r1.getArea();
	t1.getArea();
	return(0);
}
