complex0.h

我学习C++ Primer Plus过程中写下的课后作业的编程代码

#ifndef COMPLEX0_H_
#define COMPLEX0_H_
#include <iostream>

namespace COMPLEX
{
	class complex
	{
	private:
		double real;	//实数
		double imaginary;	//虚数
	public:
		complex();		//默认构造函数
		complex( double r, double i );
		~complex();
		complex operator + (const complex & c )const;
		complex operator - (const complex & c )const;
		complex operator * (const complex & c )const;
		complex operator * ( double	x )const;
		complex operator ~ ()const;
		//friends
		friend std::istream & operator>> ( std::istream & os, complex & c);
		friend std::ostream & operator<< ( std::ostream & os, const complex & c);
		friend complex operator * ( double x, const complex & c);
	};
}
