#include"Date.h"
class  Books{
public:
	string  m_ID;//编号

	Date m_publicDate;//出版日期
	double m_price;	
public:
	Books();//无参
	Books(string _id,string _bookName,string _author,string _press, Date _publicDate,double _price);//有参
	Books(Books & b);//拷贝构造函数	
	Books *next;
	friend ostream & operator<<(ostream & output,Books &b);
	friend istream &operator >>(istream & input,Books &b);
