定义一个复数类Complex，重载运算符“+”,“-”,“*”,“/”，使之能用于复数的加、减、乘、除。运算符重载函数作为Complex类的成员函数。编写程序，分别求两个复数之和、差、积和商。

本文介绍了一个使用C++实现的复数类，该类支持加、减、乘、除等基本运算，并通过示例展示了如何使用这个类进行复数的运算。代码中包含了复数的定义、构造函数、运算符重载以及显示方法。

#include <iostream>

#include <iomanip>

using namespace std;

class Complex

{

public:

    Complex();

    Complex(double r,double i);

    Complex operator+(Complex &c2);

    Complex operator-(Complex &c2);

    Complex operator*(Complex &c2);

    Complex operator/(Complex &c2);

    void display();

private:

    double real;

    double imag;

};

Complex ::Complex(){}

Complex::Complex(double r,double i)
 {
	 real=r;
	 imag=i;
 }

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

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

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

Complex Complex::operator/(Complex &c2)
{
	double d=c2.real*c2.real+c2.imag*c2.imag;
	return Complex((real*c2.real+imag*c2.imag)/d,(imag*c2.real-real*c2.imag)/d);
}

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

int main()

{

    double real,imag;

    cin>>real>>imag;

    Complex c1(real,imag);

    cin>>real>>imag;

    Complex c2(real,imag);

    cout<<setiosflags(ios::fixed);

    cout<<setprecision(2);

    Complex 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;

}
