Question

Problem description Caf´e Wafflelicious, as its very name signifies, is a cafe that sells waffles. When customers arrive at this cafe, they design the waffle they want according to the kinds of waffles, their ingredients and their prices. The waitress delivers these orders to the cook from the customer. The cook is responsible for making the waffle. You will prepare an order system in which you will check the company’s waffle orders.For example, there is a waffle order from the customer. You need to expand the functionality of the class in a transparent and dynamic way.Waffle Types (Concrete component): Normal Waffle - $13.0 Belgian Waffle - $16.0 Wrap Waffle - $13.0 Wheat Waffle - $15.0 1 Free Gluten Waffle - $17.0 Toppings (Concrete decorator): chocolate - $2.0 for each (white, milky, dark, nutella and caramel) fruits - $0.5 for each (strawberry, kiwi, pineapple and banana) sauces - $1.0 for each (chocolate, caramel and raspberry) nuts - $1.0 for each (pistachio, almond, hazelnut and walnut)
