rooms.h

这是一个我的课后习题,要求编译一个酒店管理程序.做的不好~多多执教

#include <iostream.h>
#include <stdlib.h>
#include "Tags.h"

class Rooms
{
	//struct link list for rooms
	struct Node_tag
	{
		int reservation_Number;
	    int arrival_Day;
	    int departure_Day;
		
		Node_tag *next;
	};

private:
	//all fields
	int room_number;
	bool smoking;
	static int count;
	bool empty;

public:
    //two points to contain linked list
	Node_tag *head;
	Node_tag *tail;

    //constructor(Rooms)
    Rooms(bool s=false)
	{
		empty=true;
        room_number=count++;

	}

    //add a tag object into rooms linked list
    void enTags(Tags &a)
	{

        add->reservation_Number=a.get_Reservation_Number();

		add->next=NULL;
		tail=add;
	}
	
	//remove a tag from rooms linked list
    bool deTags(Tags &a)
	{

	}
