定义一个复数类Complex，重载运算符“+”、“=”，“*”，“、”，使之能进行复数的加、减、乘、除。运算符重载函数作为Complex类得成员函数。编程序，分别求两个复数之和、差、积和商。

解答： 

#include <iostream>

#include <cmath>

using namespace std;

class Complex{

public:

Complex(double r=0,double i=0);

Complex operator +(const Complex& c);

Complex operator -(const Complex& c);

Complex operator *(const Complex& c);

Complex operator /(const Complex& c);

void print() const;

private:

double real, imag;

};

Complex::Complex(double r,double i){

real=r;

imag=i;

}

Complex Complex::operator +(const Complex& c){

double r=real+c.real;

double i=imag+c.imag;

return Complex(r,i);

}

Complex Complex::operator -(const Complex& c){

double r=real-c.real;
