#include <iostream>
#include <cmath>
using namespace std;
class Complex{
private:
double Real,Image;
public:
Complex (double r=0.0,double i=0.0){Real=r;Image=i;}
Complex(Complex &com){
Real=com.Real;
Image=com.Image;
}
void Print(){
cout<<"Real="<<Real<<'\t'<<"Image="<<Image<<endl;
}
Complex operator+(Complex);
Complex operator+(double);
Complex operator=(Complex);
Complex operator+=(Complex);
double abs(void);
Complex operator*(Complex);
Complex operator/(Complex);
};
Complex Complex::operator +(Complex c){
Complex temp(Real+c.Real,Image+c.Image);
return temp;
}
Complex Complex:: operator+(double d){
return Complex(Real+d,Image);
}
Complex Complex::operator =(Complex c){

temp.Real=c.Real;

return temp;
}
Complex Complex::operator+=(Complex c){

return temp;
}
double Complex::abs(void){
return sqrt(Real*Real+Image*Image);
}
Complex Complex::operator*(Complex c){

return Complex(Real*c.Real -Image*c.Image,Real*c.Image+c.Real *Image);
}
Complex Complex::operator/(Complex c){
double d=c.Real*c.Real+c.Image*c.Image;
return Complex((Real*c.Real+Image*c.Image)/d,(Image*c.Image-Real*c.Real)/d);
}
int main(){

c1.Print();

cout<<"c3的模为:"<<c3.abs()<<endl;

return 0;
