C++ 运算符的重载

#include <iostream>
#include <stdio.h>

using namespace std;

class Complex //复数类
{
public:
double real;//实数
double imag;//虚数
Complex(double real=0,double imag=0)
{
  this->real=real;
  this->imag=imag;
}
};

Complex operator+(Complex com1,Complex com2)//运算符重载函数
{
return Complex(com1.real+com2.real,com1.imag+com2.imag);
}

int main()
{
    Complex com1(10,10),com2(20,20),sum;
    sum=com1+com2;//或sum=operator+(com1,com2)

    cout<<"sum的实数部分为"<<sum.real<<endl;
    cout<<"sum的虚数部分为"<<sum.imag<<"i"<<endl;
    getchar();
    return EXIT_SUCCESS;
}
