基于C++實現酒店管理系統_C 語言

作者：qq_996852067 ? 更新時間： 2022-05-21 編程語言

現今大多數賓館所提供的服務樣式都各式各樣，規模大小也是各有不同，但是歸總下來，不可或缺的兩類模塊還是顧客和工作人員。由于對賓館行業內部沒有很深刻的理解，此次系統設計包括數據庫和功能模塊都是根據網上收集到的材料和個人認知上，簡單模仿和具體實現的。

為滿賓館管理的實際需求，本系統主要實現以下功能：

1、入住登記：登記所入住房間號碼，登記顧客入住時間，退房時間，個人信息（身份證號，手機號，姓名）
2、退房辦理：輸入已經入住的房間號，確認完畢即可退房。
3、房間查詢：管理員輸入正確的密碼后即可對房間狀態查詢，和具體入住信息查詢。
4、密碼修改：管理員對自身密碼進行修改，前提是先輸入正確密碼后才能實現。
5、以txt文檔的形式存儲信息數據。
6、使用類封裝。

注：代碼使用前需要先向代碼中自定義路徑下的Input.txt文檔中預存信息
