/*使用说明：1.初始化各房间数目不可轻易改动，若改动必须保证当前住户全部结账情况下。这里假定房间数60、单人间20、双人间30、三人间10*/ 代码主体设计的流程基本没问题。
主函数:
1、初始化房间
2、读取文件中原有信息
3、主菜单循环
1、录入新客人
2、结账
3、查询
4、退出
4、退出前保存信息到文件
5、释放内存
这个问题：
读取访问权限冲突
因为结构体成员变量顺序问题导致的对齐错误。
根据错误信息可以看出，问题出现在读取history成员时。
尝试修改：

char name;
char idnumber;
char telenumber;
char address;
int roomnumber;
int price;
time_t intime;
time_t outtime;
Node3* next;
