c語言購物系統(tǒng)

1、C語言課程設(shè)計報告班學(xué)號： *姓名： *指導(dǎo)老師： *日期： *中國地質(zhì)大學(xué)（武漢）計算機學(xué)院一、題目要求系統(tǒng)主要功能模塊：1，實現(xiàn)系統(tǒng)內(nèi)制卡，發(fā)卡功能。2，實現(xiàn)系統(tǒng)內(nèi)購物卡帳戶及相關(guān)帳戶管理。3，實現(xiàn)購物卡交易和合法性檢查。4，實現(xiàn)購物卡交易積分功能。5，實現(xiàn)購物卡報表功能。6，數(shù)據(jù)以文件形式存儲。提示：制卡：指申請一個購物卡，但還沒有使用。發(fā)卡：指該卡已經(jīng)起用。實現(xiàn)卡交易：指從卡中消費掉一定金額。二、需求分析根據(jù)題目要求，由于購物卡信息是存放在文件中，所以應(yīng)提供文件的輸入、輸出等操作；在程序中需瀏覽購物卡的信息，應(yīng)提供報表、查詢等操作；另外還應(yīng)提供鍵盤式選擇菜單實現(xiàn)功能選擇。三、總體設(shè)計根

2、據(jù)需求分析，可以將系統(tǒng)分為五大模塊：制卡、發(fā)卡、登陸、報表、積分。購物卡管理系統(tǒng)制卡模塊發(fā)卡模塊登錄模塊積分模塊報表模塊查詢儲蓄修改密碼消費四、詳細(xì)設(shè)計1、主函數(shù)將main()函數(shù)體內(nèi)的界面選擇部分語句單獨抽取出來作為一獨立函數(shù)，目的在于系統(tǒng)執(zhí)行完每部分功能模塊后能夠方便返回到系統(tǒng)界面。void menu()int v,w1;doprintf("tt*MENU*nn");printf("tttt 1.card-maden");printf("tttt 2.card-lifen");printf("tttt 3.card-en
