為什么這里加 system（“pause”）; 運(yùn)行不出來(lái)？

#include <iostream>
using namespace std;
class Coordinate
{
???
public:
?Coordinate(int x, int y)
?{
??// 設(shè)置X,Y的坐標(biāo)
??m_iX=x;
??????? m_iY=y;
?}
public:
?int m_iX;
?int m_iY;
};

int main(void)
{
??? // 在堆上創(chuàng)建對(duì)象指針
?Coordinate *p=new Coordinate(3,5);
??? // 打印坐標(biāo)
?cout <<"("<<p->m_iX<<","<<p->m_iY<<")"<< endl;
?
?//cout<<"("<<(*p).m_iX<<","<<(*p).m_iY<<")"<< endl;
??? // 銷毀對(duì)象指針
?delete p;
??? p=NULL;
??? //system（“pause”）;
?return 0;
}
