首先是构造函数,重载
#include <iostream>
#include <cstdio>
#include <cstring>
#include <string>
#define maxn 65540
using namespace std;
struct Node
{
int x,y;
Node (int x = 0,int y = 0):x(x),y(y) {} //构造函数
};
Node operator + (const Node& a,const Node& b)
{
return Node(a.x+b.x,a.y+b.y);
}
ostream& operator << (ostream &out,const Node& p) //重载流输出方式
{
out<<"("<<p.x<<","<<p.y<<")";
return out;
}
int main()
{
Node a,b(1,2);
Node c = a+b;
cout<<a+b<<endl;;
}
