c语言学生信息管理系统 ，建立学生信息包括姓名学号，年龄，电话号码，生日，籍贯

跪求，急啊！！！急！！！！C语言学生管理系统~

大一的时候C的作业，代码不一定很好，你看着改下就行了

原题：
请定义一个描述学生基本信息的结构，包括姓名，学号，籍贯，身份证号，年龄，家庭住址，性别，联系方式等。并定义一个结构体数组。编程：
a)
编写函数
input() , 输入基本信息（3～5条记录）；
b)
编写函数
print()，输出全体记录信息；
c)
编写函数
search(), 检索一个指定的学生信息并返回, 由主函数打印到屏幕上；
d) 说明，访问结构的时候，什么时候应该用运算符“.”，什么时候应该用运算符“->”。

说明：访问时用结构体的话用成员运算符，用指针则用指向运算符。

这个学期一开学两个星期没有上课，就搞了一个下面的小软件：

学生籍贯信息管理系统

可以实现功能：1.学生学号、姓名、籍贯等信息的录入

2.学生信息保存到磁盘，并能够从磁盘读取、显示

3.学生信息查询：
1）用学号查询并输出所查到信息

2）用姓名查询并输出查到的所有学生信息

3）用籍贯查询并输出查到的所有学生信息

4.学生信息处理：包括修改、增加、删除学生信息

在这个学生基本信息管理系统中，定义了函数void getInfo()、void SaveTxt()、void stuSaveTxt()、void showInfo()、void searchmenu()、void searchnum()、void searchname()、void searchsex()、void searchdormitory()、void countmenu()、void altermenu()、void alterstudent()、void erase()、int huoqu(int i)、进行学生信息的录入、保存、显示学生信息、按学号、姓名、性别、寝室号查询；统计学生信息、修改学生信息、删除学生信息等的实现，另外用函数实现了程序中的清屏和退出。在函数中，多次运用switch()，do while()函数，使程序简单顺利的进行。
当然，通过menu()等的菜单函数，来实现功能菜单显示在运行窗口以提示用户如何进行操作。
另外，主函数main()中，不再是全部在一个函数中实现，而是通过对函数的调用，让函数的功能进行实现。
另外，在函数中也用了大量的清屏和退出函数，使整个管理系统更为合理和完善

　　单纯只用多个数组管理学生成绩信息，不使用结构体，该程序最主要的难点是依据学号或总成绩对学生信息进行排序，借助了临时数组来标记排好序的下标。
