精选优质文档-倾情为你奉上程序设计报告基于Linux系统的学生信息管理系统功能：在Linux系统下，实现学生信息的管理功能开发环境：Linux Ubuntu 12.04，Intel 64位处理器开发语言：C语言运行环境：普通PC机编译环境：gcc Makefile本系统对学生信息进行管理，分有学生、老师、老板三种板块，不同权限的用户登录会进入不同的界面进行操作。系统主界面分为注册，登录，忘记密码，关于以及退出，如果没有这个系统的账号和密码可以进行注册，注册时候会问你要注册的权限是什么，并且根据你注册的权限进去相应的界面。登录时候需要输入账号以及密码，如果账号密码均正确将进入账号所属权限的界面；如果有错误，会根据错误类型提醒用户。忘记密码可通过管理员用户查看进行找回。关于则是一点具体信息。退出则会退出此程序。以下具体介绍每个权限中的具体功能：1. 学生界面：学生的功能包括查看学生信息，考试，提交试卷，修改密码，返回以及退出的功能。将各个函数封装成一个box，然后在主函数中进行调用，具体代码如下：box中的各函数：#include "stu_box.h"#include <stdio.h>#include <stdlib.h>#include <string.h>static void init_node(struct stu_info
