我正在建立一个航班预订系统,从我在大学的OOP课程的规范.系统必须用C#编写.我想知道解决以下问题的最佳方法是什么
The company currently operates a discount scheme. Western Isles residents get a 10% discount.
Scotia also records the island of residence of these passengers for marketing purposes. Business
travellers get a 25% discount and must supply their company name. Ordinary passengers do not
normally receive a discount unless it is part of a current promotion,in which case they receive a
5% discount.
我是否应该有乘客舱,每个独立类型的客户都是从哪一类继承的？任何有关这方面的帮助将不胜感激
