C++关系运算符重载

#include<iostream>
using namespace std;class Person {
public:string name;int age;Person(string n, int a){name = n;age = a;}//friend bool operator==(Person& p1, Person& p2);  使用友元//成员函数实现函数关系符重载==bool operator==(Person& p) {if (name == p.name && age == p.age) {return true;}return false;}//bool operator!=(Person& pp) {if (name == pp.name && age == pp.age) {return true;}return false;}
};
全局函数实现关系符重载
//bool operator==(Person& p1,Person &p2) {
//	if (p1.name == p2.name && p1.age == p2.age) {
//		return true;
//	}
//	return false;
//}
void test01()
{Person p1("huanggang",18);Person p2("huanggang",18);Person p3("huanggang", 11);Person p4("huanggang", 18);if (p1 == p2) {cout << "相等" << endl;}else {cout << "不相等" << endl;}if (p3 == p4) {cout << "相等" << endl;}else {cout << "不相等" << endl;}
}int main()
{//test01();test01();return 0;
