C++实现KFC点餐系统

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

一、题目名称：模拟肯德基收银系统
二、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。

三、算法设计：

四、代码

五、结果展示

六、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。
