    double Area ;
	
    public :

	friend ostream & operator << (ostream &, rectangle &);
 };


 istream & operator >> (istream &din, rectangle &r)
 {
	cout << "Enter rectangle Height: " ; din >> r.H ;
	cout << "Enter rectangle Width : " ; din >> r.W ;
	return (din) ;
}
ostream & operator << (ostream &dout, rectangle &r)
{
	dout << endl << endl;
	dout << "Height of rectangle: " << r.H << endl ;
	dout << "Width of rectangle: " << r.W << endl ;
	
        r.Area = r.H * r.W ;
	
        dout << "The Area of the rectangle is : " << r.Area << endl;
        getch() ;
       
        return(dout) ;
 }
