机房机位预约模拟系统—C语言课程设计(共15页)

1、精选优质文档-倾情为你奉上机房机位预约模拟一题目要求20台机器,从早八点到晚八点,每两个小时一个时间段.需要实现的功能:(1) 查询,根据输入的时间,输出机位信息.(2) 机位预定,根据输入的日期和时间段查询是否有空机位,若有则预约,若无则提供最近空机时间段.另:若用户要求在非空时间上机,则将用户信息插入该时间段的等待列表.(3) 退出预定,根据输入的时间,撤消该时间的预定.(4) 查询是否有等待信息,若有则按顺序显示联系方式,若无则显示提示信息.二需求分析根据题目要求，在程序中应实现查询，机位预定，插入等待列表，退出预定，查询等待信息等功能。还应提供键盘式选择菜单实现功能选择。而等待信息放在

2、文件里，所以在相关的模块应提供文件的输入、输出操作。三总体设计根据上面的需求分析，将这个系统的设计分为下面4个模块：机房机位预约模拟系统状态查询模块预订模块取消预订模块查询等待信息模块4详细设计 1.预处理命令及函数声明#include<stdio.h>#include<stdlib.h>#include<string.h>#define N 20#define T (time-8)/2int sum6=0;int computer620=1,1,1,1,1,1,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,
