我們在入門C++后都會自己設(shè)計一個系統(tǒng)，來檢驗自己的c++基礎(chǔ)是否牢固。而博主最近在某站上跟著黑馬一起看視頻學(xué)習(xí)c++，其中有個機(jī)房預(yù)約系統(tǒng)，博主也跟著敲了一下，接下來讓我們一起來看看程序吧。

在設(shè)計一個系統(tǒng)之前我們應(yīng)該思考系統(tǒng)的結(jié)構(gòu)，系統(tǒng)的功能以及客戶的需求等等。我設(shè)計的這個系統(tǒng)有以下功能：學(xué)生，老師及管理員三種身份登入，學(xué)生功能：申請預(yù)約，查看預(yù)約，取消預(yù)約
老師功能：查看預(yù)約，處理預(yù)約信息
管理員功能：添加用戶成員，查看機(jī)房信息，清空訂單信息，查看成員信息。

有任何問題請在下面評論，謝謝。

接下來直接上代碼：

文件結(jié)構(gòu)如下圖：
