C++ 用运算符重载 实现复数相加

#include "stdafx.h"
#include <iostream>
using namespace std;
class Complex
{public:
    Complex(){real = 0;imag = 0;}
    Complex (double r, double i){real = r ;imag = i;}
    Complex operator+(Complex &c2);
    void display();
private:
    double real;
    double imag;
};

Complex Complex :: operator+(Complex &c2)
{
    Complex c;
    c.real = real + c2.real;
    c.imag = imag + c2.imag;
    return c;
}

void Complex::display()
{
    cout<<"}"<<real<<","<<imag<<"i)"<<endl;
}

int _tmain(int argc, _TCHAR* argv[])
{
    Complex c1(3,4),c2(5,-10),c3;
    c3 = c1 + c2;
    cout<<"c1="; c1.display();
    cout<<"c2="; c2.display();
    cout<<"c1+c2="; c3.display();
    return 0;
}
