c語(yǔ)言圖書管理系統(tǒng)附源碼是一款由C語(yǔ)言編寫的圖書管理系統(tǒng)，它是由吾愛(ài)論壇網(wǎng)友分享提供的，對(duì)于學(xué)習(xí)C語(yǔ)言的朋友可以借鑒參考學(xué)習(xí)代碼的編寫，這也是在大學(xué)里初學(xué)C語(yǔ)言經(jīng)常會(huì)遇到的課題，歡迎大家下載學(xué)習(xí)。

系統(tǒng)說(shuō)明

猜測(cè)大一的同學(xué)只要是學(xué)習(xí)C語(yǔ)言的應(yīng)該最后都會(huì)有課程設(shè)計(jì)，我們一組當(dāng)時(shí)分配到的題目是寫圖書館管理系統(tǒng)。

系統(tǒng)并不是很完善，只是實(shí)現(xiàn)功能，望大佬勿噴。

其中程序的主要貢獻(xiàn)者是我舍友范同學(xué)（Robin），我是負(fù)責(zé)了其中一部分函數(shù)。

為了在課上方便演示，我們把所有的代碼全都放到一個(gè)源文件里了。

這里把源代碼給大家供大家參考。

大家在查看圖書信息之前一定要先導(dǎo)入信息（也就是7號(hào)功能），不然是讀取不到的，導(dǎo)入之前提前在盤符準(zhǔn)備好圖書 .txt 文件。

使用說(shuō)明

管理員賬戶密碼皆為admin(學(xué)習(xí)C語(yǔ)言的朋友應(yīng)該都懂)
