//Defining a class
class Rectangle {
public:
  int width, height;

  //Normal Constructor
  Rectangle(int w, int h)
  {
     width = w;
     height = h;
  }

  //Copy Constructor
  Rectangle(Rectangle &r)
  {
    width = r.width;
    height = r.height;
  }
};

void main()
{
  // Create object using Normal Constructor
  Rectangle r1(10, 15);

  // Create object using Copy Constructor
  Rectangle r2(r1);

  std::cout << r2.width << " " << r2.height<<std::endl;
  return 0;
}
