/* 题目5：教务信息管理系统
1、题目描述
设计一个教务信息管理系统，该程序具有以下功能：
（1）录入如下信息：学生基本信息：如学号、姓名、性别、年龄电、宿舍号码、话号码等。
课程基本信息：课程编号、课程名称、考试成绩、平时成绩、综合成绩、
学分、重修否等。如果重修，需要考虑重修学期、重修成绩，并且要考虑多次重修的情况。
（2）录入选课信息
（3）录入学生成绩
（3）按班统计学生选课情况及考试成绩。
（4）按课程统计学生名单及考试成绩。
（5）统计并输出每个同学已修学分及不及三格课程。
2、题目要求
（1）按照分析、设计、编码、调试和测试过程完成应用程序；
（2）学习并使用流程图等工具，并在撰写报告中使用；
（3）程序的各项功能在程序运行时，以菜单方式选择并执行；
（4）要求用户输入数据时，要给出清晰、明确的提示，包括：输入数据的内容、格式及结束方式等
（5）所有的信息存储在文件中，并实现文件读写操作。
（6）程序中用链表存放学生信息并实现增删减功能。
3、提示
（1）学生基本信息可以设计一个结构体类型
（2）自己构思并增加的除规定功能之外的新功能，酌情加分。*/
