C++ 用new动态创建对象

#include<iostream>using namespace std;class TPoint1{int x, y;public:TPoint1(int x1, int y1){//构造函数x = x1;y = y1;}void dispoint(){//输出点的信息cout<<"("<<x<<", "<<y<<")"<<endl;}};int main(){TPoint1 a(12,6);TPoint1* p = new TPoint1(5, 12);cout<<"First point: ";a.dispoint();cout<<"second point: ";p->dispoint();return 0;}
