C++學(xué)籍管理系統(tǒng)課程設(shè)計報告含代碼

1、摘要：學(xué)籍管理信息系統(tǒng)是高校管理的重要組成部分，為老師、同學(xué)提供存檔、查詢等手段。根據(jù)教學(xué)安排，我們有兩周的時間進行學(xué)籍管理信息系統(tǒng)課程設(shè)計，我們小組團結(jié)一心，分工明確，積極討論，終于在組員的努力下及老師的指導(dǎo)幫助下，我們順利完成了本次課程設(shè)計，系統(tǒng)包括學(xué)生資料設(shè)置，成績設(shè)置，成績、排名查詢，修改資料關(guān)鍵字：系統(tǒng)查詢課程設(shè)計論文管理目錄第一章緒論（1）1.1 課程設(shè)計背景11.2 課程設(shè)計目的11.3 課程設(shè)計思路1第二章系統(tǒng)總體規(guī)劃（2）2.1 前期準備22.2 系統(tǒng)功能2第三章系統(tǒng)分析設(shè)計（3）3.1 建立MFH界面及代碼設(shè)計33.2 學(xué)生資料設(shè)置及代碼設(shè)計103.3 學(xué)生成績設(shè)置及代碼設(shè)

3、信息進行管理，能夠極大的提高學(xué)生管理的效率，節(jié)約教育經(jīng)費，這也是適應(yīng)學(xué)校信息化建設(shè)發(fā)展趨勢的重要因素。因此我們有必要開發(fā)學(xué)籍管理信息系統(tǒng)。1.2 課程設(shè)計目的全面系統(tǒng)的學(xué)習(xí)面向?qū)ο蟪绦蛟O(shè)計的基本概念、基本語法和編程方法。正確理解掌握C+胸向?qū)ο蟪绦蛟O(shè)計的基本特性：類、對象、繼承與派生、多態(tài)、虛函數(shù)、模板、流類庫等。遵循軟件過程的各個環(huán)節(jié)進行系統(tǒng)分析、設(shè)計、實現(xiàn)、集成、測試，并相應(yīng)給出軟件規(guī)格說明書等制品。了解當(dāng)前常用的軟件開發(fā)工具(VisualC+),要求熟練掌握基于MFC勺程序設(shè)計，培養(yǎng)解決實際問題的能力。1.3 課程設(shè)計思路實現(xiàn)學(xué)生基本情況的錄入、修改、刪除等基本操作；能實現(xiàn)學(xué)生成績的錄入

4、、修改、刪除等基本操作；能方便的對學(xué)生的各個學(xué)期成績進行統(tǒng)計；能具有成績統(tǒng)計、排名等功能；可行性分析由于本系統(tǒng)管理的對象單一，都是在校學(xué)生，且每個數(shù)據(jù)內(nèi)容具有較強的關(guān)聯(lián)性，涉及的計算過程不是很復(fù)雜。第二章系統(tǒng)總體規(guī)劃2.1 前期準備學(xué)習(xí)C+6.0課本理論知識，查找、搜集相關(guān)資料，討論出具體思路、方法，在整個過程中周老師給了我們必不可少的許多指導(dǎo)，使我們能夠順利地完成前期各項工作。2.2 系統(tǒng)功能基于系統(tǒng)需求分析，該系統(tǒng)具有以下基本功能：用戶管理：管理系統(tǒng)操作人員，設(shè)置操作人員賬號、密碼、用戶資料等。用戶資料：學(xué)生通過登錄，可以查詢到自己的資料、成績、排名，同時可以修改密碼。成績管理：管理員根據(jù)

5、學(xué)生成績保存到系統(tǒng)中，同時可計算出綜合排名、平均分等信息。功能圖登錄系統(tǒng)。管理員登陸查詢成績排名平均分設(shè)置成績基礎(chǔ)數(shù)據(jù)管理：維護學(xué)生資料，主要包括院系、專業(yè)設(shè)置，聯(lián)系方式、學(xué)號等個人信息設(shè)置等。學(xué)生登錄查詢用戶資修改密碼第三章系統(tǒng)分析設(shè)計3.1 建立MF3界面及代碼設(shè)計#include"stdafx.h"/頭文件#include"學(xué)生信息管理系統(tǒng).h"#include"學(xué)生信息管理系統(tǒng)Dlg.h"#include"xueshengziliao2.h”#include"xueshengziliao1.h”#inclu
