这篇CFSDN的博客文章C++实现KFC点餐系统由作者收集整理，如果你对这篇文章有兴趣，记得点赞哟.

本文实例为大家分享了C++实现KFC点餐系统的具体代码，供大家参考，具体内容如下 。

1、题目名称：模拟肯德基收银系统 2、题目内容:

同学们应该都去麦当劳或肯德基吃过快餐吧？请同学们参考肯德基官网的信息模拟肯德基快餐店的收银系统，合理使用C++或Java或Python结合设计模式（2种以上）至少实现系统的以下功能:

1.正常餐品结算和找零。 2.基本套餐结算和找零。 3.使用优惠劵购买餐品结算和找零。 4.可在一定时间段参与店内活动（自行设计或参考官网信息）。 5.模拟打印小票的功能（写到文件中）.

基本要求:

1.程序设计风格良好，控制台界面友好，最多两人一组完成任务。 2.实现功能测试代码，确保程序的健壮性。 3.画出使用的设计模式图.

提高要求:

1.实现可视化界面（使用MFC）。 2.实现会员储值卡功能，完成储值卡消费。 实现当天营业额和餐品销量计算和统计，用数据库记录.

3、算法设计:

C++实现KFC点餐系统

6、总结 。

1.本次作业为KFC点餐系统，刚开始的想法是用Java做，但是在看了许多资料结合自己的情况，最终采用C++来写程序，C++确实较Java熟悉了很多。 2.这次只做了基本要求，没有做提高要求，我会在后面的学习中，结合可视化界面和数据库连接，将点餐系统完善。 3.主要运用到设计模式中的策略模式和工厂模式，其中工厂模式负责生产餐厅中的各种食物的对象，策略模式负责在生成小票时避免出现冗杂的if语句。 4.从RPG游戏和KFC点餐系统两次的作业来看，这两次的代码认为量来说都是比较大的，对于其中的一些函数功能的使用，还有设计模式的理解并且不到位.

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我.
