스마트 포인터 심플예제

 

처음 스마트포인터를 봤을때 참 기발하다고 생각했다~~ 캬캬

 

 

 

#include<iostream>
using namespace std;

 

class Point
{
     int x;
     int y;
public:
     Point(int _x = 0, int _y = 0) : x(_x) , y(_y) { }
     void Print() const { cout<< x << ',' << y << endl;}
};

class PointPtr
{
     Point *ptr;
public:
     PointPtr(Point *p): ptr(p) {}
     ~PointPtr()
 {
      delete ptr;
 }
 Point* operator->() const
 {
      return ptr;
 }
 Point& operator*() const
 {
      return *ptr;
 }
};

 

int main()
{
     PointPtr p1 = new Point(2,3);
     PointPtr p2 = new Point(5,5);

     

p1->Print();
p2->Print();
     

cout<<endl;

     

(*p1).Print();
(*p2).Print();

 

 

return 0;

}
