本文实例为大家分享了C语言实现酒店管理系统的具体代码，供大家参考，具体内容如下

代码如下：

#include<bits/stdc++.h> #include<conio.h>#include <windows.h>#include<string.h>#include<time.h> #define NUM 1000 //控制房间个数int j;void LoginRoom();//登记房屋void SearchRoom();//搜寻房屋void ChangeRoom();//更换住房void OutRoom();//退房void save();//保存信息void load();//载入信息//struct Totalstruct Total{ char Name[20];
