C++實(shí)現(xiàn)KFC點(diǎn)餐系統(tǒng)

更新時(shí)間：2020年07月23日 10:03:33 作者：Cynthia!

這篇文章主要為大家詳細(xì)介紹了C++實(shí)現(xiàn)KFC點(diǎn)餐系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了C++實(shí)現(xiàn)KFC點(diǎn)餐系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

一、題目名稱：模擬肯德基收銀系統(tǒng)
二、題目?jī)?nèi)容：

同學(xué)們應(yīng)該都去麥當(dāng)勞或肯德基吃過(guò)快餐吧？請(qǐng)同學(xué)們參考肯德基官網(wǎng)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(jié)合設(shè)計(jì)模式（2種以上）至少實(shí)現(xiàn)系統(tǒng)的以下功能：

1.正常餐品結(jié)算和找零。
2.基本套餐結(jié)算和找零。
3.使用優(yōu)惠劵購(gòu)買餐品結(jié)算和找零。
4.可在一定時(shí)間段參與店內(nèi)活動(dòng)（自行設(shè)計(jì)或參考官網(wǎng)信息）。
5.模擬打印小票的功能（寫(xiě)到文件中）。

基本要求：

1.程序設(shè)計(jì)風(fēng)格良好，控制臺(tái)界面友好，最多兩人一組完成任務(wù)。
2.實(shí)現(xiàn)功能測(cè)試代碼，確保程序的健壯性。
3.畫(huà)出使用的設(shè)計(jì)模式圖。

提高要求：

1.實(shí)現(xiàn)可視化界面（使用MFC）。
2.實(shí)現(xiàn)會(huì)員儲(chǔ)值卡功能，完成儲(chǔ)值卡消費(fèi)。
實(shí)現(xiàn)當(dāng)天營(yíng)業(yè)額和餐品銷量計(jì)算和統(tǒng)計(jì)，用數(shù)據(jù)庫(kù)記錄。

三、算法設(shè)計(jì)：

四、代碼

五、結(jié)果展示

六、總結(jié)

1.本次作業(yè)為KFC點(diǎn)餐系統(tǒng)，剛開(kāi)始的想法是用Java做，但是在看了許多資料結(jié)合自己的情況，最終采用C++來(lái)寫(xiě)程序，C++確實(shí)較Java熟悉了很多。
2.這次只做了基本要求，沒(méi)有做提高要求，我會(huì)在后面的學(xué)習(xí)中，結(jié)合可視化界面和數(shù)據(jù)庫(kù)連接，將點(diǎn)餐系統(tǒng)完善。
3.主要運(yùn)用到設(shè)計(jì)模式中的策略模式和工廠模式，其中工廠模式負(fù)責(zé)生產(chǎn)餐廳中的各種食物的對(duì)象，策略模式負(fù)責(zé)在生成小票時(shí)避免出現(xiàn)冗雜的if語(yǔ)句。
4.從RPG游戲和KFC點(diǎn)餐系統(tǒng)兩次的作業(yè)來(lái)看，這兩次的代碼認(rèn)為量來(lái)說(shuō)都是比較大的，對(duì)于其中的一些函數(shù)功能的使用，還有設(shè)計(jì)模式的理解并且不到位。

更多學(xué)習(xí)資料請(qǐng)關(guān)注專題《管理系統(tǒng)開(kāi)發(fā)》。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
