求两个复数的加减乘除。

要求使用c++ class编写程序。可以创建如下class

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>

using namespace std;

class Complex {
public:
    Complex(double r = 0.0, double i = 0.0): real(r), imag(i) {}
    Complex operator+ (const Complex &c2) const;
    Complex operator- (const Complex &c2) const;

    /*实现下面三个函数*/
    Complex operator* (const Complex &c2) const;
    Complex operator/ (const Complex &c2) const;
    friend ostream & operator<< (ostream &out, const Complex &c);

private:
    double real;
    double imag;
};

Complex Complex::operator+ (const Complex &c2) const {
    return Complex(real + c2.real, imag + c2.imag);
}

Complex Complex::operator- (const Complex &c2) const {
    return Complex(real - c2.real, imag - c2.imag);
}

int main() {
    double real, imag;
    cin >> real >> imag;
    Complex c1(real, imag);
    c
