C++课程设计--毕业选题系统（MFC）

课设题目

毕业选题系统

课设要求

设计内容
    针对大四学生毕业设计选题需求，设计毕业设计选题系统。教师可对毕业设计题目进行管理:学生可以选择题目，同一个题目可能会被多个学生选取:
其后教师可对选题学生进行确认。主要功能包括:

1. 用户管理
2. 教师信息(姓名，工号，密码，所在院系等)的录入、修改和删除
3. 学生信息(姓名，学号，密码，所在专业，个人简介等)的录入、修改和删除
4. 毕业设计题目信息(题目名称，适用专业，难度)的录入、修改、删除
5. 根据 不同条件查询毕业设计题目信息
6. 学生查看所在专业的毕业设计题目，并且进行选题
7. 教师查看选题情况，并确认选题学生
8. 可按专业统计并显示学生最终的选题结果，并将报表导出到文件中
