本文主要是介绍一个简单酒店住宿信息管理系统(C++),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
住宿信息包括:住宿编号、姓名、身份证号码、联系电话、入住时间、房号、单价、入住接待人姓名、退房时间、退房接待人姓名、优惠费用、使用房内小物品费用、应付费用、备注。
本酒店住宿信息管理系统具有以下功能:
(1)系统以菜单方式工作,执行一次操作后重新显示一次菜单;
(2)住宿信息利用文件保存;
(3)住宿信息的录入;
(4)修改住宿信息;
(5)删除住宿信息;
(6)按条件(住宿编号、姓名、身份证号码、联系电话、入住时间、房号)查询住宿信息;
(7)退房时根据退房时间与单价自动计算应付费用,应付费用=单价*入住天数﹣优惠费用+使用房内小物品费用,入住天数根据入住时间和退房时间自动计算;
(8)按天、周和月统计酒店的营业额。
