C++實現(xiàn)KFC點餐系統(tǒng)
更新時間：2020年07月23日 10:03:33 作者：Cynthia!
這篇文章主要為大家詳細介紹了C++實現(xiàn)KFC點餐系統(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)KFC點餐系統(tǒng)的具體代碼，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(tǒng)
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信息模擬肯德基快餐店的收銀系統(tǒng)，合理使用C++或Java或Python結合設計模式（2種以上）至少實現(xiàn)系統(tǒng)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(yōu)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信息）。
5.模擬打印小票的功能（寫到文件中）。
基本要求：
1.程序設計風格良好，控制臺界面友好，最多兩人一組完成任務。
2.實現(xiàn)功能測試代碼，確保程序的健壯性。
3.畫出使用的設計模式圖。
提高要求：
1.實現(xiàn)可視化界面（使用MFC）。
2.實現(xiàn)會員儲值卡功能，完成儲值卡消費。
實現(xiàn)當天營業(yè)額和餐品銷量計算和統(tǒng)計，用數(shù)據庫記錄。
三、算法設計：
四、代碼

五、結果展示
六、總結
1.本次作業(yè)為KFC點餐系統(tǒng)，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，最終采用C++來寫程序，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，我會在后面的學習中，結合可視化界面和數(shù)據庫連接，將點餐系統(tǒng)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對象，策略模式負責在生成小票時避免出現(xiàn)冗雜的if語句。
4.從RPG游戲和KFC點餐系統(tǒng)兩次的作業(yè)來看，這兩次的代碼認為量來說都是比較大的，對于其中的一些函數(shù)功能的使用，還有設計模式的理解并且不到位。
