機房機位預(yù)約模擬系統(tǒng)—C語言課程設(shè)計

1、C語言課程設(shè)計報告機房機位預(yù)約模擬一題目要求20臺機器,從早八點到晚八點,每兩個小時一個時間段.需要實現(xiàn)的功能:(1) 查詢,根據(jù)輸入的時間,輸出機位信息.(2) 機位預(yù)定,根據(jù)輸入的日期和時間段查詢是否有空機位,若有則預(yù)約,若無則提供最近空機時間段.另:若用戶要求在非空時間上機,則將用戶信息插入該時間段的等待列表.(3) 退出預(yù)定,根據(jù)輸入的時間,撤消該時間的預(yù)定.(4) 查詢是否有等待信息,若有則按順序顯示聯(lián)系方式,若無則顯示提示信息.二需求分析根據(jù)題目要求，在程序中應(yīng)實現(xiàn)查詢，機位預(yù)定，插入等待列表，退出預(yù)定，查詢等待信息等功能。還應(yīng)提供鍵盤式選擇菜單實現(xiàn)功能選擇。而等待信息放在文件里，

2、所以在相關(guān)的模塊應(yīng)提供文件的輸入、輸出操作。三總體設(shè)計根據(jù)上面的需求分析，將這個系統(tǒng)的設(shè)計分為下面4個模塊：機房機位預(yù)約模擬系統(tǒng)狀態(tài)查詢模塊預(yù)訂模塊取消預(yù)訂模塊查詢等待信息模塊4詳細設(shè)計 1.預(yù)處理命令及函數(shù)聲明#include<stdio.h>#include<stdlib.h>#include<string.h>#define N 20#define T (time-8)/2int sum6=0;int computer620=1,1,1,1,1,1,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,
