儀器儀表管理系統(tǒng)—C語(yǔ)言課程設(shè)計(jì)

1、儀器儀表管理1.題目要求.【要求】 系統(tǒng)功能的基本要求：（1） 新的儀器儀表信息的錄入；（2） 在借出、歸還、維修時(shí)對(duì)儀器儀表信息的修改；（3） 對(duì)報(bào)廢儀器儀表信息的刪除；（4） 按照一定的條件查詢(xún)符合條件的儀器儀表信息；查詢(xún)功能至少應(yīng)該包括儀器儀表基本信息（如儀器儀表名字、儀器儀表編等）的查詢(xún)、按時(shí)間點(diǎn)（借入時(shí)間、借出時(shí)間、歸還時(shí)間）查詢(xún)等（5） 對(duì)查詢(xún)結(jié)果的輸出。 【提示】 數(shù)據(jù)結(jié)構(gòu)采用結(jié)構(gòu)體。儀器儀表信息包括儀器儀表名、儀器儀表編號(hào)、購(gòu)買(mǎi)時(shí)間、借入時(shí)間、借出時(shí)間、歸還時(shí)間、維修時(shí)間、狀態(tài)信息（0代表可借出，1代表已借出，2代表正在維修）等。.需求分析根據(jù)題目要求，需要把儀器儀表信息的的數(shù)

2、據(jù)存儲(chǔ)在文件里，所以需要提供文件的輸入輸出等操作；在程序中要提供修改，刪除，查找等操作；另外還應(yīng)該提供鍵盤(pán)式選擇菜單實(shí)現(xiàn)功能選擇。2.功能實(shí)現(xiàn)設(shè)計(jì)2.1總體設(shè)計(jì) 儀器儀表管理系統(tǒng)添加查詢(xún)修改刪除退出系統(tǒng)功能模塊圖2.2詳細(xì)設(shè)計(jì)1. 主函數(shù)主函數(shù)一般設(shè)計(jì)得比較簡(jiǎn)潔，只提供輸入輸出和功能處理的函數(shù)調(diào)用。其各功能模塊用菜單方式選擇。本題將main（）函數(shù)體內(nèi)的界面選擇部分語(yǔ)句單獨(dú)抽取出來(lái)作為一獨(dú)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?！境绦颉?main()menu();菜單部分設(shè)計(jì)如下：【流程圖】顯示一系列功能選項(xiàng) 輸入n，判斷n是否是17 N Y根據(jù)n的值調(diào)用各功能模塊函
