1）录入：录入信息（学号，宿舍号，性别，姓名，所属院系）
2）插入：给出姓名和学号执行插入后，查询是否被插入；
3）删除：给出姓名或学号执行删除后，查询是否被删除；
4）交换：给出两学生的姓名或学号执行交换后，查询是否被交换；
5）查询：给出房间号，列出该房间的入住学生即可
6）统计：每个宿舍没住满情况，显示
问题补充：帮个忙啦，哪位大哥可以编出来？
设计一个结构类型和一维数组类型，用来保存作业登记信息。
(1) 按照分析、设计、编码、调试和测试的软件开发过程完成这个应用程序；
(2) 为各项操作功能设计一个菜单。应用程序运行后，先显示这个菜单，然后用户通过菜单项选择希望进行的操作项目。
大家帮帮忙啊，谁能写个啊！急用！！！！
