#include<iostream>using namespace std;class Wages//“工资”类{    double base;//基本工资    double bonus;//奖金    double tax;//税金public:    Wages(double CBase, double CBonus,double CTax):  base(CBase), bonus(CBonus),tax(CTax) {}    double getPay()const;//返回应付工资额    Wages operator+(Wages w)const;//重载加法};double Wages::getPay()const{    return base+bonus-tax;}Wages Wages::operator+(Wages w)const{    return Wages(base+w.base,         bonus+w.bonus,tax+w.tax);}int main(){    Wages wl(2000,500,100),w2(5000,1000,300);    cout<<(wl+w2).getPay()<<endl;    return 0;}

运行结果：

8100

分析：

+号运算符重载，实现奖金基本工资和税金的加法，类的成员函数做运算符重载
