Complex（复数运算）

复数的运算规则在下面代码中有具体说明

#include 
#define EXP 0.0000000000
using namespace std;

class Complex 
{ 
public: 
// 1.完成四个默认成员函数 
	Complex(double real = 8.0, double image = -6.0)//构造函数
	{
		_real=real;
		_image=image;
		cout<<"Complex(double real,double image)"<EXP)
		{
			cout<<_real<<"+"<<_image<<"i"<(const Complex& d)
	{
		if(this->_image==0 && d._image==0)
			return this->_real>d._real;
		else 
			cout<<"error";
	}
	bool operator<(const Complex& d)
	{
		if(this->_image==0 && d._image==0)
			return this->_real_real==d._real&&this->_image==d._image;
	}
	bool operator!=(const Complex& d)
	{
		return  this->_real != d._real
			|| this->_image != d._image;
	}
// 3.前置后置++和+/+=的实现 
	Complex& operator++()//前置++
	{
		this->_real+=1;
		return *this;
	}
	Complex operator++(int)//后置++
	{
		Complex tmp(*this);
		this->_real+=1;
		return tmp;
	}
	Complex& operator+=(Complex& d)
	{
		this->_real=(this->_real + d._real);
		this->_image=(this->_image  + d._image) ;
		return *this;
	}
	Complex operator+(const Complex& d)
	{
		Complex ret;
		ret._real = (this->_real + d._real);
		ret._image = (this->_image + d._image);
		return ret;
	}
protected: 
	double _real; 
	double _image; 
};
