1 【课程设计】教务信息管理系统
Time Limit:1000MS Memory Limit:65535K
题型: 人工评判题 语言: 无限制
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、宿舍号码、电话号码等。
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级课程。
（6）实现单词组合查询课程名，例如输入“JAVA+设计”查询，可以查到如下课程
《JAVA语言与程序设计》
《JAVA程序设计》
《JAVA语言与算法设计》
注：因为上面课程名中均包含“设计”和“教程”两个单词
同理，输入“JAVA+算法+设计”查询，则只能查到《JAVA语言与算法设计》
任务要求：
（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）记录添加删除操作时，先从文件载入数据，用链表存放，批量操作完后，数据从链表写入文件。
（7）【加分选做】根据学生的选课，能够生成一个学生的课表（形式与我校教务处系统中的课表相似），并将时间有冲突的课程标记为红色
输入格式
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。
