本文详细介绍了如何使用C++实现复数的加法运算，包括构造复数、加法操作及显示复数的方法。

#include <iostream.h>
class Complex{
public:
	Complex()
	{
	 real=0;
	 imag=0;
	}
	Complex(double r,double i)
	{
	 real=r;
	 imag=i;
	}
    Complex operator +(Complex &);
	Complex operator +(int &);
	friend Complex operator +(int &,Complex &);
	void display()
	{
	 cout<<"("<<real<<"+"<<imag<<"i)"<<endl;
	}
private:
	double real;
	double imag;
};
Complex Complex::operator +(Complex &c2)
{
 return Complex(real+c2.real,imag+c2.imag);
}
Complex Complex::operator +(int &i)
{
 return Complex(real+i,imag);
}
Complex operator +(int &i,Complex &c3)
{
 return Complex(i+c3.real,c3.imag);
}
int main()
{
 int i=2;
 Complex c1(2,4),c2(1,2),c3,c4,c5;
 c3=c1+c2;
 cout<<"c3=c1+c2=";
 c3.display();
 c4=c1+i;
 cout<<"c4=c1+i=";
 c4.display();
 c5=i+c2;
 cout<<"c5=i+c2=";
 c5.display();
 return 0;
}
