#include <iostream>
using namespace std;

{
public:
	Complex(){real=0;imag=0;}
	Complex(int r,int i)
	{

		imag=i;
	}
	Complex complex_add(Complex &c2)//复数相加函数

	c3=c1.complex_add(c2);
	cout<<"c1=";

	c2.display();
	cout<<"c1+c2=";
	c3.display();
	return 0;
}

#include <iostream>
using namespace std;
class Complex
{
public:
	Complex(){real=0;imag=0;}
	Complex(int r,int i)
	{
		real=r;
		imag=i;
	}
	Complex operator+(Complex &c2)//重载运算符的函数，用于复数相加
	{
		Complex c;
		c.real=real+c2.real;
		c.imag=imag+c2.imag;
		return c;
	}
	void display();
private:

};
void Complex::display()
{
	cout<<'('<<real<<','<<imag<<"i)"<<endl;
}
int main()
{
	Complex c1(3,4),c2(-5,10),c3;
	c3=c1+c2;//系统自动调用c1.operator+(c2)来完成c1+c2;
	cout<<"c1=";
	c1.display();
	cout<<"c2=";
	c2.display();
	cout<<"c1+c2=";
	c3.display();
	return 0;
}
重载运算符函数的一般格式如下：
函数类型 operator运算符名称(参数列表)
{对运算符重载的处理}
