一、前言

ckquote>

本项目为学生信息管理系统࿰c;使用C语言编写。

二、项目介绍

ckquote>

开发环境：

基于windows 11系统下的Visual Studio 2022开发

提供功能：

  • 学生信息的查询、修改、增加、删除
  • 账户信息的查询、修改、增加、删除

登陆级别：

  • 管理员级别-老师-0࿰c;可使用所有系统功能。
  • 普通 级别-学生-1࿰c;仅查询功能。

配置文件：

  • configure.txt 存放登陆账户信息文件和学生信息文件的绝对路径࿰c;每个路径独占一行。
  • usrer_cfg.txt 登录账户信息࿰c;0表示管理员账户࿰c;1表示普通用户。
  • student_cfg.txt 学生信息。

注意： 配置文件要和可执行文件在同一目录下࿰c;或者在程序中fopen的时候写入配置文件路径。
用户文件和登陆账户文件格式如下
usrer_cfg.txt

<code>账户名 密码 登陆级别 code>

student_cfg.txt

<code>id 姓名 课程id 成绩 课程id 成绩 课程id 成绩 ... code>

登陆界面
首先选择身份c="https://img-blog.csdnimg.cn/b549a3e9e9e44847ad6236c805e44348.png" alt="在这里插入图片描述" />
登录界面输入的账户名和密码应该是usrer_cfg.txt配置文件中存在的记录。
