C語(yǔ)言課程設(shè)計(jì)行編輯系統(tǒng)

1、c語(yǔ)言課程設(shè)計(jì)目 錄1、需求分析；2、系統(tǒng)總框圖；3、每個(gè)模塊的設(shè)計(jì)分析；4、列出所有定義的函數(shù)及說(shuō)明；5、舉例說(shuō)明1、2個(gè)比較有特點(diǎn)的算法；6、數(shù)據(jù)分析。完備性、健壯性等；7、存在的問(wèn)題與不足及對(duì)策；8、使用說(shuō)明（操作手冊(cè)）；9、學(xué)習(xí)心得前 言計(jì)算機(jī)科學(xué)技術(shù)的發(fā)展，不僅極大地促進(jìn)了整個(gè)科學(xué)技術(shù)的發(fā)展，而且明顯地加快了經(jīng)濟(jì)信息化和社會(huì)信息化的進(jìn)程。因此，計(jì)算機(jī)教育在全國(guó)備受重視，計(jì)算機(jī)知識(shí)與能力已成為21世紀(jì)人才素質(zhì)的基本要素之一。如今，高等教育的計(jì)算機(jī)教育發(fā)展十分迅速。十多年前，只有部分理工科專業(yè)開(kāi)設(shè)計(jì)算機(jī)課程。今天，幾乎所有高校的所有專業(yè)都開(kāi)設(shè)了程度不同的計(jì)算機(jī)課程。人們已經(jīng)認(rèn)識(shí)到，計(jì)算機(jī)

2、知識(shí)已成為當(dāng)代知識(shí)分子知識(shí)結(jié)構(gòu)中不可缺少的重要組成部分。而除了掌握計(jì)算機(jī)的基礎(chǔ)知識(shí)和操作的基本能力外，掌握一門(mén)高級(jí)編程語(yǔ)言，并可以熟練運(yùn)用它，已成為當(dāng)代大學(xué)生綜合能力必要組成。計(jì)算機(jī)技術(shù)發(fā)展如此迅猛，計(jì)算機(jī)應(yīng)用如此廣泛，需要學(xué)習(xí)的東西愈來(lái)愈多，而我們的總學(xué)時(shí)是有限的。一般來(lái)說(shuō)，計(jì)算機(jī)課程學(xué)習(xí)可以分為兩部分：一部分是理論課程學(xué)習(xí)，一部分是上機(jī)應(yīng)用實(shí)習(xí)。根據(jù)我們專業(yè)的性質(zhì)和要求，則應(yīng)側(cè)重于上機(jī)操作運(yùn)用。為此，學(xué)校特意在暑期最后一星期安排了32個(gè)學(xué)時(shí)的上機(jī)實(shí)習(xí)?，F(xiàn)將一星期的實(shí)習(xí)內(nèi)容及結(jié)果分析分列如下：簡(jiǎn)單的行編輯器一 題目要求1 設(shè)置一個(gè)簡(jiǎn)單的行編輯器，每行以回車結(jié)束。2 數(shù)據(jù)以文件形式存儲(chǔ)。3 編

3、輯器具有查找，替代，修改數(shù)據(jù)的功能。二 需求分析根據(jù)題目要求，數(shù)據(jù)以文件的形式存儲(chǔ)，所以應(yīng)提供文件的輸入，輸出等操作；還需要文件具有查找，替換，修改數(shù)據(jù)的功能。三 總體設(shè)計(jì)根據(jù)上面的需求分析，可以將這個(gè)系統(tǒng)的設(shè)計(jì)分為如下七大模塊：編輯，查找，修改，刪除，替換，保存，退出。簡(jiǎn)單的行編輯器系統(tǒng)編輯替換刪除修改保存退出查找四 詳細(xì)設(shè)計(jì)1 主函數(shù)為了各模塊的獨(dú)立性，主函數(shù)一般設(shè)計(jì)得比較簡(jiǎn)單，本系統(tǒng)主要用主函數(shù)打開(kāi)上次保存的數(shù)據(jù)和進(jìn)入主菜單函數(shù)流程圖main()file *fp;fp=fopen(record.txt,w);/*在c:documents and settingsadministrator
