KFC点餐模拟

其他 2020-01-23 13:34:47 阅读次数: 0

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。
3.实现当天营业额和餐品销量计算和统计，用数据库记录。
