帮忙改代码 给高分 （28号结帖）

[kakalong]

题目：



学生信息管理系统
至少有学号、姓名、性别、系名、班级名、出生年月、学院住址、电话号码
要求：至少有输入数据，显示数据，进一步可以设计编辑、修改、删除等功能。增加排序，查询数据等功能。
界面要求全屏设计，比较好看，所有功能可以反复使用，最好是用一个菜单管理起来。
数据类型至少要用到结构体和数组，进一步可以使用文件进行存储和管理。



设计的大致过程和步骤:
1,首先要明确,这个主要是对结构体数组进行操作!考虑学生信息主要分为这样几个变量,
学号, 姓名,性别,系名,班级名，出生年月，学院地址，电话号码！
2,排序: 排序是根据学号来排名次的,然后按降序方式排列记录到数组中!
3,插入,修改,删除: 在记录学生信息的数组中,第一,找到所要操作的记录,然后对相应的记录进行操作(寻找一条记录,可以根据,姓名,编号,成绩等来查找)
1>插入操作,输入一条

行有点不太对齐，复制下来就好了。
9是后来改的，case‘9’那里注释应为查询。
也希望有高手给我的程序提提意见~：）
