exists.5, take the point class as an example, the workaround is: Add a new class Upoint, including the point object and the reference count U, as follows:Class Point{PublicPoint (): _x (0), _y (0) {}Point (int x,int y): _x (x), _y (y) {}Point (const point RHS): _x (rhs._x), _y (rhs._y) {}point SetX (int x){_x = x;return *this;}int GetX (){return _x;}point sety (int y){_y = y;return *this;}int GetY (){return _y;}Privateint_x;int_y;};#include "Point.h"
