本文例項為大家分享了C++實現KFC點餐系統的具體程式碼，供大家參考，具體內容如下

一、題目名稱：模擬肯德基收銀系統
二、題目內容：

同學們應該都去麥當勞或肯德基吃過快餐吧？請同學們參考肯德基官網的資訊模擬肯德基快餐店的收銀系統，合理使用C++或Java或Python結合設計模式（2種以上）至少實現系統的以下功能：

1.正常餐品結算和找零。
2.基本套餐結算和找零。
3.使用優惠劵購買餐品結算和找零。
4.可在一定時間段參與店內活動（自行設計或參考官網資訊）。
5.模擬列印小票的功能（寫到檔案中）。

基本要求：

1.程式設計風格良好，控制檯介面友好，最多兩人一組完成任務。
2.實現功能測試程式碼，確保程式的健壯性。

提高要求：

1.實現視覺化介面（使用MFC）。
2.實現會員儲值卡功能，完成儲值卡消費。
實現當天營業額和餐品銷量計算和統計，用資料庫記錄。

三、演算法設計：

四、程式碼

五、結果展示

六、總結

1.本次作業為KFC點餐系統，剛開始的想法是用Java做，但是在看了許多資料結合自己的情況，最終採用C++來寫程式，C++確實較Java熟悉了很多。
2.這次只做了基本要求，沒有做提高要求，我會在後面的學習中，結合視覺化介面和資料庫連線，將點餐系統完善。
3.主要運用到設計模式中的策略模式和工廠模式，其中工廠模式負責生產餐廳中的各種食物的物件，策略模式負責在生成小票時避免出現冗雜的if語句。
4.從RPG遊戲和KFC點餐系統兩次的作業來看，這兩次的程式碼認為量來說都是比較大的，對於其中的一些函式功能的使用，還有設計模式的理解並且不到位。
