pyqt5的kfc点餐系统问题

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）。

本题采用工厂方法模式和抽象工厂模式：

工厂方法模式：

核心工厂类不再负责所有产品的创建，而是将具体创建的工作交给子类去做，成为一个抽象工厂角色，仅负责给出具体工厂类必须实现的接口，而不接触哪一个产品类应当被实例化这种细节。

抽象工厂模式:

客户类和工厂类分开。消费者任何时候需要某种产品，只需向工厂请求即可。消费者无须修改就可以接纳新产品。缺点是当产品修改时，工厂类也要做相应的修改。如：如何创建及如何向客户端提供。

抽象食物——AbstractFood

食物接口——Food

抽象基类——汉堡类，鸡肉类，甜点类，饮品类和套餐

具体食物类

抽象工厂——生产汉堡类，鸡肉类，甜点类，饮品类和套餐

具体工厂——生产具体食物

客户类——调用抽象工厂

测试类——建立客户点餐

public abstract class AbstractFood {

    protected String kind;

    //数量

    protected int num;

    //价格

    protected float price;

 

    //合计

    public float totalPrice(){

        return this.num * this.price;

    }
