Question

谁能帮忙写一个学生公寓管理系统的C语言程序啊？？谢谢啦 ！！！

2：项目背景
学生公寓管理软件
（1） 需要处理的基础数据
该校区拥有学生公寓不超过1500套，每套房可住2人，3人或4人，公寓信息包括：房间号，面积，层次，朝向，基本设施，定价，现状（应住人数，实住人数）。学生信息包括：姓名，学号，所在学院，年级，入住日期，打算离开日期，所住房间号，预订房间号。
（2） 用菜单选择并完成下述功能
1） 入住，即将学生信息添加到公寓信息库中
2） 预定，根据公寓信息，学生可预订某套房间
3） 换房，修改公寓信息库
4） 统计，公寓入住情况统计，月，年公寓出租情况
5） 查询，查询房源和学生信息

Answer 1

你看一下这个有没有错，有些地方你可以改一下，好比不超过1500套，看看其他地方有没有需要改的，或者有什么错误，有什么不符合的，你可以稍微修改一下，我觉得这个应该 差不多符合你的要求了，大体上差不多，有必要自己修改吧
