本文介绍了一个简单的C++程序，该程序定义了一个Point结构体，并实现了两个Point实例之间的加法运算符重载。此外，还重载了流插入运算符以方便输出Point对象。通过这个例子，读者可以了解到如何在C++中使用结构体以及如何进行运算符重载。

#include<iostream>
using namespace std;
struct Point{
    int x,y;
    Point(int x=0, int y=0):x(x),y(y){}
};
Point operator + (const Point& A, const Point& B){
    return Point(A.x + B.x, A.y + B.y);
}
ostream& operator << (ostream &out, const Point& p){
    out << "(" << p.x << "," << p.y << ")";
    return out;
}
int main()
{
    Point a, b(1,2);
    a.x = 3;
    cout << a+b << "\n";
    return 0;
}

#include<iostream>
using namespace std;
struct Point{
    int x,y;
    Point (int x=0, int y=0) { this->x = x; this->y = y; }
};
Point operator + (const Point& A, const Point& B){
    return Point(A.x + B.x, A.y + B.y);
}
ostream& operator << (ostream &out, const Point& p){
    out << "(" << p.x << "," << p.y << ")";
    return out;
}
int main()
{
    Point a, b(1,2);
    a.x = 3;
    cout << a+b << "\n";
    return 0;
}
