# 学生信息管理系统
## 概述
本套系统是我大一程序设计进阶课的结课作业，实现了登录、文件读写，以及对数据的查询、排序等操作。
1、单人完成代码的编写（本以为几百行能解决的系统，前前后后写了两千多行，虽然很多是注释...）
2、本套系统基于Windows系统，执行C11标准。
3、项目使用Clion集成环境开发。
4、项目模块化，将不同功能写在不同的源文件中，通过头文件集中管理和调用。
5、用户输入检测，只允许用户输入规则内的数据，不合法的数据一律提示重新输入。
**相关文件的解释：**
| 文件 | 解释 |
| ----------------------------------------- | -------------------------------------------- |
| for_main.h | 包含主函数所需的所有头文件 |
| user.h | 定义登录用户的相关信息结构体 |
| stu_info.h | 定义用于存储学生信息的结构体 |
| for_function_module.h | 包含每个模块函数所需的头文件以及主函数的声明 |
| main.c | 主函数 |
| main_menu.h & main_menu.c | 主菜单模块 |
| secondary_menu.h & secondary_menu.c | 二级菜单模块 |

## 功能详解
### 一、主菜单
本系统设置有权限，只有注册账号后输入正确的账号密码才能进入。
主菜单设置有输入内容的控制功能，即检测输入内容是否合法：

### 二、登录模块
![](https://yvling-blog-image-1257337367.cos.ap-shanghai.myqcloud.com/%E5%8D%9A%E5%AE%A2/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E7%AE%A1%E7%90%86%E7%B3%BB%E7%BB%9F/2022-04-23/%E7%99%BB%E5%BD%95%E6%A8%A1%E5%9D%97.png)
输入正确的账号密码即可进入系统。
### 三、二级菜单
![](https://yvling-blog-image-1257337367.cos.ap-shanghai.myqcloud.com/%E5%8D%9A%E5%AE%A2/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E7%AE%A1%E7%90%86%E7%B3%BB%E7%BB%9F/2022-04-23/%E4%BA%8C%E7%BA%A7%E8%8F%9C%E5%8D%95.png)
二级菜单中提供5个功能，输入代码即可跳转至对应功能。
二级菜单设置有输入内容的控制功能，即检测输入内容是否合法：
![](https://yvling-blog-image-1257337367.cos.ap-shanghai.myqcloud.com/%E5%8D%9A%E5%AE%A2/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E7%AE%A1%E7%90%86%E7%B3%BB%E7%BB%9F/2022-04-23/%E4%BA%8C%E7%BA%A7%E8%8F%9C%E5%8D%95%E6%A3%80%E6%B5%8B%E8%BE%93%E5%85%A5.png)
### 四、学生信息添加模块
![](https://yvling-blog-image-1257337367.cos.ap-shanghai.myqcloud.com/%E5%8D%9A%E5%AE%A2/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E7%AE%A1%E7%90%86%E7%B3%BB%E7%BB%9F/2022-04-23/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E6%B7%BB%E5%8A%A0%E6%A8%A1%E5%9D%97.png)
在此模块中，需依次输入学生的学号、姓名、性别、年龄、语文成绩、数学成绩、英语成绩。
输入结束后，学生信息被保存在stu_info目录下的stu_info.txt文件中：
![](https://yvling-blog-image-1257337367.cos.ap-shanghai.myqcloud.com/%E5%8D%9A%E5%AE%A2/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E7%AE%A1%E7%90%86%E7%B3%BB%E7%BB%9F/2022-04-23/%E5%AD%A6%E7%94%9F%E4%BF%A1%E6%81%AF%E4%BF%9D%E5%AD%98.png)
输入结束后，提示是否继续添加，选择”是“则当前界面清除，进入下一轮的输入，否则返回二级菜单。
本模块同样设置有输入内容检测功能，非法输入无效。
