本文介绍: cout
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。
