定義一個復(fù)數(shù)類Complex,重載運算符“+”,“-”,“*”,“/”,使之能用于復(fù)數(shù)的加、減、乘、除.

定義一個復(fù)數(shù)類Complex,重載運算符“+”,“-”,“*”,“/”,使之能用于復(fù)數(shù)的加、減、乘、除.
運算符重載作為Complex的類的成員函數(shù),編程序,求兩個復(fù)數(shù)的和,差,積,商.
程序：
#include
using namespace std;
class Complex //定義complex類
{public:
Complex(){real=0;imag=0;} //定義構(gòu)造函數(shù)
Complex(double r,double i){real=r;imag=i;} //構(gòu)造函數(shù)重載
Complex operator+(Complex &c2); //聲明復(fù)數(shù)相加的函數(shù)
Complex operator-(Complex &c2); //聲明復(fù)數(shù)相減的函數(shù)
Complex operator*(Complex &c2); //聲明復(fù)數(shù)相乘的函數(shù)
Complex operator/(Complex &c2); //聲明復(fù)數(shù)相除的函數(shù)
void display();
private:
double real; //實部
double imag; //虛部
};
Complex Complex::operator+(Complex &c2) //定義復(fù)數(shù)相加的函數(shù)
{Complex c;
c.real=real+c2.real; //實部相加
c.imag=imag+c2.imag; //虛部相加
return c;}
Complex Complex::operator-(Complex &c2) //定義復(fù)數(shù)相減的函數(shù)
{Complex c;
c.real=real-c2.real;
c.imag=imag-c2.imag;
return c;}
Complex Complex::operator*(Complex &c2) //定義復(fù)數(shù)相乘的函數(shù)
{Complex c;
c.real=real*c2.real-imag*c2.imag;
c.imag=imag*c2.real+real*c2.imag;
return c;}
Complex Complex::operator/(Complex &c2) //定義復(fù)數(shù)相除的函數(shù)
{Complex c;
c.real=(real*c2.real+imag*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag);
c.imag=(imag*c2.real-real*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag);
return c;}
void Complex::display() //定義輸出函數(shù)
{cout
