/**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*/

C语言：宾馆客房信息管理系统
那只是语法上没有错误，但是写出来没实现功能是另外一回事，分模块儿进行应该好点。
C语言程序设计 客房管理系统
这个很简单的，就是一个读写文件功能和指针。
读写文件 fopen() fread() fwrite() ，其中需要打开为binary，或者将结构转化为字符数组。
当读入一个结构，就将它当作结构指针赋值。得到指针后就可以操作了。
查询功能可能需要遍历文件。应有一个循环。并且可以判断是哪个条件。while( 指针-成员 == 条件 ){ 处理 }。
当然新用户登记也是读写文件，如果要安全好一点的可以查个MD5算法加密一下。
以下是一个保存的实例（手写的，错误难免）：
bool saveto(char *filename, hotel *proom)
{
//检查是否有信息
FILE *fp = fopen(filename, "r");
if( fp )//打开失败
{
fp = fopen(filename, "w");//写方式打开
if( !fp )//打开成功
{
goto _WRITE;
}
else return false; //又失败了，退出
}
else //只读方式打开成功了！
{
fclose(fp); //关闭原来的
}
//追加方式打开
fp = fopen(filename, "a");
if( !fp )
{
goto _WRITE;
}
else return false; //如果追加方式没打开
_WRITE:
//写入数据
fwrite((void*)proom, sizeof(hotel), sizeof(hotel), fp);
//关闭文件
fclose(fp);
//退出
goto _END;
_END:
return true;

求一个C语言程序段可以在酒店客房管理系统中实现计时的功能，谢谢啦！
这。。 太简单了。。
cus 的结构体，增加 日期时间 描述。。。 如：struct tm inDateTime;
struct tm {//time.h 头文件中结构定义
int tm_sec; /* Seconds */
int tm_min; /* Minutes */
int tm_hour; /* Hour (0 - 23) */
int tm_mday; /* Day of month (1 - 31) */
int tm_mon; /* Month (0 - 11) */
int tm_year; /* Year (calendar year minus 1900) */
int tm_wday; /* Weekday (0 - 6; Sunday is 0) */
int tm_yday; /* Day of year (0 -365) */
int tm_isdst; /* Nonzero if daylight saving time is in effect. */
};
struct tm *gmtime(const time_t *timer);//相关函数,获取当前时间
gettime(cus.inDateTime);
printf("\n\r顾客可以住在:"); 的上面加入代码：gettime(cus.inDateTime); 保存信息的时候，记录保存信息时的时间。
结算的时候。。。 再用 gettime(tmpCurDateTime);
然后自己在 tmpCurDateTime 和 cus.inDateTime 做加减法。。。
相关定义在 time.h 中
