如何使用C++編寫實(shí)現(xiàn)圖書管理系統(tǒng)

這篇文章將為大家詳細(xì)講解有關(guān)如何使用C++編寫實(shí)現(xiàn)圖書管理系統(tǒng)，小編覺得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。

具體內(nèi)容如下

為圖書管理人員編寫一個(gè)圖書管理系統(tǒng)，圖書管理系統(tǒng)的設(shè)計(jì)主要是實(shí)現(xiàn)對(duì)圖書的管理和相關(guān)操作，包括3個(gè)表：
圖書信息表——存儲(chǔ)圖書的基本信息，包括書號(hào)、書名、作者、出版社、出版日期、存館數(shù)量、定價(jià)等。
讀者信息表——存儲(chǔ)讀者的基本信息，包括學(xué)號(hào)、姓名、學(xué)院、專業(yè)班級(jí)等。
圖書借閱表——存儲(chǔ)讀者借書的相關(guān)信息，包括學(xué)號(hào)、姓名、書號(hào)、書名、借閱日期、應(yīng)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(hào)、書名、作者、出版社、出版日期、存館數(shù)量、定價(jià)等。

2、圖書信息查詢：分別按書名, 按作者名,
按出版單位等進(jìn)行查詢。

3、圖書信息排序：按書號(hào)、書名等按升序進(jìn)行排序。

4、圖書信息的修改、刪除：按書號(hào)或書名進(jìn)行圖書的修改和刪除。

5、讀者信息添加功能：包括學(xué)號(hào)、姓名、學(xué)院、專業(yè)、班級(jí)等。

6、讀者信息查詢：分別按學(xué)號(hào)、姓名、班級(jí)等進(jìn)行查詢。

7、讀者信息排序：按學(xué)號(hào)、學(xué)院等按升序進(jìn)行排序。

8、讀者信息的修改、刪除：按學(xué)號(hào)+姓名進(jìn)行讀者信息的修改和刪除

9、圖書借閱：輸入學(xué)號(hào)+書號(hào)，如果該書圖書信息表中的存館數(shù)量大于0，則可以借出，借出相應(yīng)數(shù)量后修改圖書信息表中的存館數(shù)量，在圖書借閱表添加該同學(xué)的借閱。

10、圖書歸還：輸入學(xué)號(hào)+書號(hào)，修改圖書信息表中的存館數(shù)量，在圖書借閱表中記錄該同學(xué)的歸還時(shí)間。

11、圖書借閱查詢：分別按學(xué)號(hào)、書名、學(xué)院等進(jìn)行查詢。
