這篇文章將為大家詳細講解有關如何使用C++編寫實現圖書管理系統，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。
具體內容如下
為圖書管理人員編寫一個圖書管理系統，圖書管理系統的設計主要是實現對圖書的管理和相關操作，包括3個表：
圖書信息表——存儲圖書的基本信息，包括書號、書名、作者、出版社、出版日期、存館數量、定價等。
讀者信息表——存儲讀者的基本信息，包括學號、姓名、學院、專業班級等。
圖書借閱表——存儲讀者借書的相關信息，包括學號、姓名、書號、書名、借閱日期、應還日期、歸還日期等。
用菜單選擇方式完成了以下功能：
1、圖書信息添加功能：包括書號、書名、作者、出版社、出版日期、存館數量、定價等。
2、圖書信息查詢：分別按書名, 按作者名,
按出版單位等進行查詢。
3、圖書信息排序：按書號、書名等按升序進行排序。
4、圖書信息的修改、刪除：按書號或書名進行圖書的修改和刪除。
5、讀者信息添加功能：包括學號、姓名、學院、專業、班級等。
6、讀者信息查詢：分別按學號、姓名、班級等進行查詢。
7、讀者信息排序：按學號、學院等按升序進行排序。
8、讀者信息的修改、刪除：按學號+姓名進行讀者信息的修改和刪除
9、圖書借閱：輸入學號+書號，如果該書圖書信息表中的存館數量大于0，則可以借出，借出相應數量后修改圖書信息表中的存館數量，在圖書借閱表添加該同學的借閱。
10、圖書歸還：輸入學號+書號，修改圖書信息表中的存館數量，在圖書借閱表中記錄該同學的歸還時間。
11、圖書借閱查詢：分別按學號、書名、學院等進行查詢。
