基于Linux系統(tǒng)的學生信息管理系統(tǒng)(共13頁)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上程序設計報告基于Linux系統(tǒng)的學生信息管理系統(tǒng)功能：在Linux系統(tǒng)下，實現(xiàn)學生信息的管理功能開發(fā)環(huán)境：Linux Ubuntu 12.04，Intel 64位處理器開發(fā)語言：C語言運行環(huán)境：普通PC機編譯環(huán)境：gcc Makefile本系統(tǒng)對學生信息進行管理，分有學生、老師、老板三種板塊，不同權限的用戶登錄會進入不同的界面進行操作。系統(tǒng)主界面分為注冊，登錄，忘記密碼，關于以及退出，如果沒有這個系統(tǒng)的賬號和密碼可以進行注冊，注冊時候會問你要注冊的權限是什么，并且根據(jù)你注冊的權限進去相應的界面。登錄時候需要輸入賬號以及密碼，如果賬號密碼均正確將進入賬號所屬權限的界面；

2、如果有錯誤，會根據(jù)錯誤類型提醒用戶。忘記密碼可通過管理員用戶查看進行找回。關于則是一點具體信息。退出則會退出此程序。以下具體介紹每個權限中的具體功能：1. 學生界面：學生的功能包括查看學生信息，考試，提交試卷，修改密碼，返回以及退出的功能。將各個函數(shù)封裝成一個box，然后在主函數(shù)中進行調(diào)用，具體代碼如下：box中的各函數(shù)：#include "stu_box.h"#include <stdio.h>#include <stdlib.h>#include <string.h>static void init_node(struct stu_i
