9、;···················（30）一、 题目要求要求编写一个旅馆客房管理系统，系统包括新用户登录功能、统计功能、查询功能、修改功能。建立如下结构体：struct Clientchar name20; int sex; int age; char ID_card20;/身份证号码； int year; int month; int date;/居住时间； ;struct Hotel int ro

10、om_ID;/房间号； int tel; int price; int sign;/标记房间是否为空； struct Client Client_list;/实现结构体的嵌套； sumN;二、需求分析根据题目要求，房间信息数据存放在一个文本文件中；通过文件的输入和输出来实现新用户登录、统计、查询、修改等各项功能；且各项功能能独立完成，不受其它工程是否完成的影响；程序中应设有主菜单函数，通过主菜单函数可以调用各个功能函数，各个功能函数操作完成后可以回到主菜单，等待下一个操作；还应设有菜单选项，能通过键盘操作实现选择；同时，应有通道退出程序；三、总体设计通过分析，整个系统应包括以几个模板：登录模板
