酒店管理系统
给定酒店管理和用户数据: 酒店数据:
Hotel Name Room Available Location Rating Price per Room
H1 4 Bangalore 5 100
H2 5 Bangalore 5 200
H3 6 Mumbai 3 100
用户数据:
User Name UserID Booking Cost
U1 2 1000
U2 3 1200
U3 4 1100
任务是回答以下问题。
- 打印酒店数据。
- 按名称对酒店进行排序。
- 按最高等级对酒店进行排序。
- 打印班加罗尔位置的酒店数据。
- 按最大可用房间数对酒店进行排序。
- 打印用户预订数据。
机器编码回合涉及在几个小时内解决一个设计问题。 它要求基于一组特定的需求设计和编码一个干净的、模块化的和可扩展的解决方案。
进场:
- 为酒店数据和用户数据创建类。
- 初始化存储酒店数据和用户数据的变量。
- 为访问酒店数据和用户数据的酒店和用户类创建对象。
- 初始化保存酒店数据和用户数据的两个向量数组。
- 逐一解答以上问题。
下面是上述方法的实现。
