C++實現(xiàn)簡易圖書館管理系統(tǒng)

更新時間：2022年03月11日 15:03:51 作者：維維sanguine

這篇文章主要為大家詳細介紹了C++實現(xiàn)簡易圖書館管理系統(tǒng)，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了C++實現(xiàn)簡易圖書館管理系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

思路

在本程序中共有四個類：

book類：此類有書的基本信息：書名，編號，作者，價格等，和基本的get()和set()方法。類圖如下：

library類：此類中有一個存放的書的數(shù)組，并且可以對書進行，查詢，借閱，歸還，添加，等相關(guān)操作。類圖如下：

reader_infor類：此類中有讀者的相關(guān)信息：名字，學(xué)號，年級，借書數(shù)量。和基本的get()和set()方法，類圖如下：

reader_admin類：此類中有一個存放讀者對象的數(shù)組，并且可以進行添加讀者，修改讀者信息等操作。類圖如下：

登陸頁面如下

讀者頁面

管理員頁面

在本程序過程中的不足：

1.書和讀者的存儲是通過靜態(tài)數(shù)組實現(xiàn)的，如果用動態(tài)數(shù)組的話更好一點。
2.還有一些其他點感覺寫的不是很好，但還不知道要怎么改。
后面有時間會再完善一下。
