学生考勤信息管理 系统


1 建立文件
(1)考勤记录文件使用指定文件名 ARecord.txt；
(2)可以不保存输入记录，但需要确认是否保存输入记录
2.文件的存取和显示
(1)可以单独存取文件；
(2)可以随时显示内存中记录的全部内容；
3 删除记录
(1)可以按“学号”或“姓名”方式删除记录；
(2)能给出被删除的信息，进行删除，如果没有要删除的信息，输出没有找到的信息；
4 查询记录
(1)可以按“姓名”或“学号”方式查询个人信息和考勤登记信息记录
(2)可以按“任课教师”或“课程名称”方式查询课程信息
(3)能给出查询记录的信息；
(4)如果查询的信息不存在，输出没有找到的信息；
5 统计记录
(1)可以显示某生某门课考勤信息，并统计各类违纪情况次数
(2)可以显示某人所有门课考勤信息，并统计各类违纪情况次数
(3)可以显示某班所有课程考勤信息，并统计各类违纪情况次数
6 备份功能
(1)  编写函数 Backupdata 实现将 ARecord.txt 内容复制到备份文件 backup.txt 中，要求
不能使用该两个文件以外的任何文件。
7 整体功能
(1)可以随时检索、删除、或增加新记录，保存或取消新的记录
(2)姓名可由 16 位字符和数字的混合编码组成

(3)使电话号码可由 11 位字符和数字组成
(4)将输出信息加上输出信息栏，例如
7 测试数据要求
(1)不少于 3 门课信息（高数、英语、程序设计）。
(2)不少于 1 个班，每班不少于 10 个同学。每人每门课的考勤信息不少于 5 次。

只完成功能，未经调试，你可以自行调试

/*
1.阅读完此注释后请删除.
2.自定义path,path2,path3,不支持中文,新建一个空白文档ARecord.txt
3.把本txt重命名为xxx.c
4.在TC上运行程序
5.本程序没有实现功能5-统计信息,正因不完美才完美
6.TC不支持中文,所以本程序运行时显示的都是英文,具体含义查看英文单词对应意思或者看注释

为什么输入班级时候会自动跳出来了？？我用的是TC3.0

自动跳出来是退出了运行的界面

班级没输对吧

是输入了学生学号，再输入要查看的考勤信息就会退出来

没输入对不是应该弹出message no found吗？

输入了这个后就出来了

运行是可以运行的

你看下ARecord.txt里面有没有数据？需要先把数据存进去才能读到
