C语言程序设计 酒店管理 急急急急 求编程高手

、酒店房间登记与计费管理

问题描述：

已知在酒店中有10个房间，每个房间的信息包括房间号，每天住宿价格，设计一程序，完成以下功能：

1) 从键盘输入客户的入住信息（包括：客户姓名，身份证号，开始入住时间、退房时间（假设客户入住时就确定什么时候退房）、入住房间号），需要完成以下功能：

l 入住房间号是否存在，开始入住时间，退房时间格式是否合法（格式为：YYYY-MM-DD,如2009-01-02）

l 输入入住信息时需要完成以下校验：该房间是否当前已经入住，如果是提示用户不能入住，检查身份证号是否为15位或18位，如果不是则提示错误

l 输入入住信息时，需要根据入住时间和退房时间，自动计算入住天数（假设入住时间不会跨年），并根据相应房间的住宿价格，计算住宿费用

2) 根据房间号，查询住宿情况

3) 根据房间号和统计时间段（开始和结束时间，不跨年）统计房间产生的住宿费用

提示：

l 酒店中的10个房间，可以采用结构体数组实现，每个数组元素表示一个房间，房间的信息表示为：房间号，价格

l 定义一个日期结构体保存日期，具体信息为：年、月、日

l 定义一个链表表示客户的入住信息，结构体信息包括：客户姓名，身份证号，开始入住时间、退房时间，入住房间号，入住天数，入住价格、住宿费用（入住天数，入住价格、住宿费用的信息在输入入住信息时计算出来）

l 判断入住时间和退房时间的格式是否合法时，需要判断长度是否为10，第5位和第8位是否为’-’，字符，将1-4位表示的年份，6-7位表示的月份，9-10位表示的日期分别转换成整数。判断是否满足构成日期的条件闰年月份只能是1-12之间的数，如果是闰年，二月可以是29天否则不能大于28，1，3，5，7，8，10，12月可以是31天，其余只能小于等于30（建议写成函数）。

l 计算入住天数，因为入住时间不会跨年，因此，可以根据月份和日期，计算入住时间到退房时间之间的天数。

l 判断房间是否当前已经入住需要查询入住信息链表，在该链表中是否存在退房时间比入住时间大的记录，如果有，则表示已经入住

l 统计时间段内房间产生的住宿费用时，需要根据开始统计的时间和结束统计时间查询入住信息链表，会有四种情况：1、查询记录的入住日期大于开始统计时间、退房日期小于结束统计时间，累加该记录的住宿费用；2、查询记录的入住日期小于开始统计时间，但退房日期大于开始统计时间，需要计算退房时间到开始统计时间的天数乘以价格再累加；3、查询记录的入住日期小于结束统计时间，但退房日期大于结束统计时间，需要计算入住时间到结束统计时间的天数乘以价格再累加；4、开始统计日期大于入住时间，结束统计日期小于退房时间，需要计算结束统计日期到开始统计日期的天数，乘以价格再累加。其余表示不在该统计时间段内，不产生入住费用

/**该函数为内部数据维护，不提供输入数据服务。实体完整性，参照完整性，用户自定义完整性
出现错误则将错误输出到doc文档。
错误范围暂时定义如下：
1.同一房间的客户房间号不同(同房搜索！)

2.实缴费用大于应缴费用。(同房搜索！)

3.同一个客户在同一天两次住进宾馆(全表搜索！身份证号和入住日期相同)

4.同一身份证号，姓名和性别不同(全表搜索！)

另外，应该完成的任务有：
5.计算客户的应缴费用->对cost操作，需要用到：time,unit_price

6.计算客房的总住户人数（包括当前住户）->对totalclient操作，需要用到：没有

7.重新修订当前住户数->对currentclient进行操作，需要用到：time

8.计算客房的总计收入->对income进行操作，需要用到：fee

9.当前住户的实缴费用清零->对fee进行操作，需要用到：time

完成这些操作的先后顺序为：7->6->5->9->8->2->1->3->4*/
