1、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；

2、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 #include #include static void init_node(struct stu_info *head, struct stu_info info)strcpy(head-name, info.name

3、);strcpy(head-sex, info.sex);head-age = info.age;strcpy(head-cid, info.cid);strcpy(head-tel, info.tel);strcpy(head-addr, info.addr);strcpy(head-object, info.object);head-next = head;head-prev = head;static void _add(struct stu_info *a, struct stu_info *new, struct stu_info *b)a-next = new;new-next =
