C++詳細(xì)實現(xiàn)完整圖書管理功能
更新時間：2022年05月05日 15:06:29 作者：工藤學(xué)編程
隨著網(wǎng)絡(luò)技術(shù)的高速發(fā)展，計算機(jī)應(yīng)用的普及，利用計算機(jī)對圖書館的日常工作進(jìn)行管理勢在必行，本篇文章涵蓋一個圖書管理系統(tǒng)的全部實現(xiàn)代碼,大家可以查缺補漏，提升水平
圖書管理系統(tǒng)功能概覽：
- 登錄，注冊
- 學(xué)生,老師借書，查看自己當(dāng)前借書情況，還書。
- 管理員增加書，查看當(dāng)前借閱情況，查看當(dāng)前所有借閱人，圖書信息。
代碼概覽：
各個模塊主要負(fù)責(zé)功能
COperationManagement.h 負(fù)責(zé)登錄，注冊，管理員，將圖書，初始化操作，將借閱信息等從文件中讀取出來，放入容器中，便于操作，不用一直對文件進(jìn)行I/O.
CBook.h 用于對書抽象，并實現(xiàn)了>>的重載，便于文件讀入，讀出
CUser.h 工具人，作為老師，學(xué)生的父類
CStudent.h 對學(xué)生進(jìn)行的抽象
CTeacher.h 對老師進(jìn)行的抽象
CAdministrator.h 對管理的抽象
CManagementBooks.h 用戶所有的相關(guān)操作的中間執(zhí)行者，有設(shè)計模式中代理的思想
源.cpp 界面的的實現(xiàn)與系統(tǒng)入口
說明：代碼100%完整，如果大家不想CV，也可以私聊我發(fā)你完整代碼，還有就是文件讀入建議大家都直接放在相應(yīng)項目里面，不然就寫絕對路徑。有問題歡迎大家在評論區(qū)提問，喜歡就點個贊咯！
