c语言酒店入住系统课程设计

好的，下面是一个基于C语言的酒店入住系统课程设计方案：

1. 系统需求分析
- 酒店管理员需要能够添加、编辑和删除酒店房间信息
- 客人需要能够浏览酒店房间信息，并且进行预订
- 酒店管理员需要能够管理客人的预订信息，并且进行确认或取消操作
- 客人需要能够查看自己的预订信息，并且能够修改或取消预订
- 酒店管理员需要能够查看房间的占用情况和客人入住信息

2. 系统设计
- 数据结构设计：设计房间、客人和预订信息的数据结构，并且建立它们之间的关系
- 系统功能设计：实现管理员添加、编辑和删除房间信息的功能，客人浏览和预订房间的功能，管理员管理客人预订信息的功能，客人查看和修改预订信息的功能，管理员查看房间占用情况和客人入住信息的功能

3. 系统实现
- 使用C语言实现系统的业务逻辑和数据访问层
- 使用控制台展示系统的界面
- 使用文件存储系统的数据，例如使用文本文件存储房间、客人和预订信息

以下是一个基于C语言的酒店入住系统的简单实现代码示例，仅供参考：

#include <stdlib.h>
#include <string.h>

#define MAX_ROOMS 100
