二、設計與實現

1. 模塊結構圖及各模塊的功能

模塊結構圖如下：

本酒店客房管理系統有兩個模塊：管理員模塊和操作員模塊。

管理員模塊的功能有：

• 管理員登錄：根據輸入賬號密碼登錄進入管理員權限

• 操作員管理

  • 查看操作員信息
  • 增加操作員信息
  • 刪除操作員信息
  • 修改操作員信息

• 酒店客房管理

  • 查看酒店客房信息
  • 修改酒店客房信息

操作員模塊的功能有：

• 操作員登錄：根據輸入賬號密碼登錄進入操作員權限
• 查看客房信息
• 客房的預訂
• 客房的入住
• 客房的退房
• 預訂查詢：根據房號和姓名查詢預訂信息
• 客房查詢：根據房號查詢房間信息
• 住客查詢：根據姓名查詢住客信息

2. 數據類型的設計和説明

函數調用關係

Room類

Room類的數據類型如下：

​ 在本項目的設計中，Room是酒店客房的抽象，而Room數組是酒店的抽象。

​ 友元函數RoomInit：進行酒店房間初始化。本項目初始化了20間客房的類型和價格，並將酒店客房信息保存在“酒店房間信息.xls”文件中。

Operator類

​ 在本項目中，Operator是酒店操作員的抽象，並用一個Operator數組保存操作員信息。

​ 友元函數OperatorInit()：進行操作員信息的初始化。本項目初始化了10位操作員的賬號和密碼，並將酒店客房信息保存在“操作員賬户信息.txt”文件中。

​ 友元函數OperatorLogin()：登錄操作員賬號。該函數傳入Operator數組並返回登錄操作員在數組的第幾個元素。

​ 成員函數WriteRoomInformation(Room*)：將Room數組中的信息寫入到“酒店房間信息.xls”文件中。該函數是一個輔助函數，當Room數組的信息進行修改時，將調用該函數修改文件相應內容。

​ 實現操作員相應功能的成員函數如下：

• ViewRoomInformation(Room*)：查看酒店客房的基本信息。該信息不包括住客的基本信息。
• ReserveRoom(Room*)：預訂客房。該函數打印空閒房間讓用户選擇、並輸入用户的姓名、身份證號、聯繫方式等基本信息。
• CheckIn(Room*)：入住房間。該函數先詢問客户是否預訂房間，若預訂需對比信息才能入住，若未預訂則打印空閒房間並輸入個人信息實現入住。
• CheckOut(Room*)：住客退房。該函數輸入退房的房號並比對住客信息，如一致方可退房、將該房間的信息置空。
• RoomQuery(Room*)：客房查詢。輸入查詢房號可打印房間信息。
• BookQuery(Room*)：預訂查詢。輸入預訂房號和姓名可查詢預訂信息。
• GuestQuery(Room*)：住客查詢。輸入客户姓名可查詢客户信息。
• OperatorQuit()：操作員退出登錄。返回主登錄菜單或退出程序時將調用該函數。

​ 以上操作員的所有操作均會保存在“操作員工作日誌.xls”文件中。工作日誌的時間由當前系統時間獲得。

Administrator類

​ 在本項目中，Administrator是酒店管理員的抽象。

​ 構造函數Administrator()：初始化管理員賬號和密碼。在本項目中，管理員賬號和密碼被初始化後不可在程序中進行修改。

​ 友元函數OperatorLogin()：登錄管理員賬號。該函數比對輸入賬號密碼與管理員賬號密碼是否一致。

​ 成員函數WriteOperatorInformation(Operator*)：將Operator數組中的信息寫入到“操作員賬户信息.txt”文件中。該函數是一個輔助函數，當Operator數組的信息進行修改時，將調用該函數修改文件相應內容。

​ 實現管理員相應功能的成員函數如下：

• ViewOperatorInformation(Operator*)：查看所有操作員的賬號、密碼。
• AddOperatorInformation(Operator*)：增加操作員信息。
• DeleteOperatorInformation(Operator*)：刪除操作員信息。
• ModifyOperatorInformation(Operator*)：修改操作員信息。
• ViewRoomInformation(Room*)：查看酒店所有客房的類型與價格。
• ModifyRoomInformation(Room*)：修改酒店客房數量、類型和價格。修改後將酒店客房信息寫入“酒店房間信息.xls”文件中。

3. 關鍵功能的實現

修改操作員信息

​ 修改操作員信息的功能通過Administrator::ModifyOperatorInformation函數實現。

​ 流程圖如下：

​ 實現源代碼如下：

void Administrator::ModifyOperatorInformation(Operator* operators)
{
    ViewOperatorInformation(operators);
    int choose;
    string UserName_,Password_;
    cout<<"\t\t#請選擇要修改的操作員信息的序號: ";
    cin>>choose;
    int num = choose;
    for(int x=0;x<=choose;x++){
        if(operators[x].UserName==""){
            num++;
        }
    }
    if(operators[num-1].UserName==""){
        cout<<"\t\t#修改失敗！該操作員不存在！"<<endl;
        system("pause");
        return;
    }
    cout<<"\t\t#請輸入修改操作員賬號: ";
    cin>>UserName_; operators[num-1].UserName=UserName_;
    cout<<"\t\t#請輸入修改操作員密碼: ";
    cin>>Password_; operators[num-1].Password=Password_;
    WriteOperatorInformation(operators);
}

三、課程設計總結

Pains

​ 在設計本系統的過程中，我花費了很多時間和心思讓該程序對用户更友好，努力設計使得程序更方便使用。在調試過程中我也遇到不少異常，包括由於編譯器編碼語言導致的程序運行異常，我查詢多篇文章後將所有異常解決，最終完成了本課程設計。

​ 在編寫本設計報告的過程中，發現自己的程序中，結構化設計等方面仍有不足，對於實際問題的解決還可以進一步改進（如增加金額結算功能等）。在後續的程序設計中，我會對本項目進行完善，達到更優。

​ 本程序設計花費了我不少心思，但是苦中有樂，我在編寫程序的過程中獲得了樂趣與滿足感，也進一步加深了自己對於程序設計的思考，有很大收穫。

Gains

​ 通過本系統的設計，我提高了分析和解決實際問題的能力，鞏固所學C++的知識，加強對結構化程序設計的思想。我全面系統地學習了面向對象程序設計的基本概念、基本語法和編程方法，獨立完成了有一定工作量的程序設計任務，強調好的程序設計風格。
