#include <iostream>using namespace std;class Complex{public:    Complex(){real=0;imag=0;}    Complex(double r,double i){real=r;imag=i;}    Complex operator+(const Complex &c2);    Complex operator-(const Complex &c2);    Complex operator*(const Complex &c2);    Complex operator/(const Complex &c2);    void display();private:    double real;    double imag;};Complex Complex::operator+(const Complex &c2){    Complex c;    c.real=real+c2.real;    c.imag=imag+c2.imag;    return c;}Complex Complex::operator-(const Complex &c2){    Complex c;    c.real=real-c2.real;    c.imag=imag-c2.imag;    return c;}Complex Complex::operator*(const Complex &c2){    Complex c;    c.real=real*c2.real;    c.imag=imag*c2.imag;    return c;}Complex Complex::operator/(const Complex &c2){    Complex c;    c.real=real/c2.real;    c.imag=imag/c2.imag;    return c;}void Complex::display(){    cout<<'('<<real<<','<<imag<<')'<<endl;}int main(){    Complex c1(3,4),c2(5,-10),c3;    cout<<"c1=";    c1.display();    cout<<"c2=";    c2.display();    c3=c1+c2;    cout<<"c1+c2=";    c3.display();    c3=c1-c2;    cout<<"c1-c2=";    c3.display();    c3=c1*c2;    cout<<"c1*c2=";    c3.display();    c3=c1/c2;    cout<<"c1/c2=";    c3.display();    return 0;}

运行结果：
