【C++中级项目】机房预约系统-阿里云开发者社区

引言

机房资源在现代社会中起着越来越重要的作用，为了高效地管理和利用机房资源，我们设计了一个基于C++的机房预约系统。该系统能够实现学生或教职工对机房进行预约、查询和管理等操作，提高机房资源的利用率和管理效率。

背景和需求分析

当前，大学机房资源管理普遍存在以下问题：

学生和教职工需要手动填写纸质申请表格，工作效率低下。
预约冲突经常发生，造成资源浪费和冲突处理困难。
难以对机房使用情况进行统计和分析。

因此，我们的机房预约系统有以下主要需求：

学生和教职工可以通过登录系统进行机房预约。
系统能够检测预约冲突并及时提示用户。
管理员能够对机房进行管理和统计。

系统设计

基于以上需求，我们设计了如下系统模块：

用户模块：包括学生和教职工用户，负责用户登录、注册和修改个人信息等功能。
机房模块：负责机房资源的维护，包括增加、删除和查询机房等操作。
预约模块：负责预约机房和处理预约冲突等操作。
管理模块：负责管理员登录和对机房资源进行管理和统计。

系统实现

我们使用C++语言进行系统开发，主要采用以下技术和方法：

面向对象编程思想：使用类和对象进行模块封装和功能实现。
文件读写操作：使用文件存储机房和用户信息，实现数据的持久化。
错误处理机制：通过异常处理和错误提示，保证系统的稳定性和可靠性。

结果与分析

经过实际测试，我们的机房预约系统实现了预约、查询和管理等功能，并且能够准确检测出预约冲突并及时提示用户。系统界面操作简单直观，用户易于上手。通过系统统计功能，管理员能够方便地获取机房使用情况和预约记录，便于管理和决策。

首先，选择身份后进入系统

若选择学生身份，输入用户名密码之后进入学生子菜单，可申请或查看、取消预约

预约流程：

查看预约：

若选择教师身份，输入职工号，用户名和密码后，进入教师子菜单

在这里审核预约：

若选择管理员身份，输入用户名和密码后进入管理员子菜单

可添加学生或老师账号

可查看学生或老师的账号

查看机房或清空预约

总结与展望

本次开发了一个基于C++的机房预约系统，实现了高效的机房资源管理。然而，目前系统还存在一些局限性，比如用户界面可视化程度不高，操作不够友好。后续也希望读者提出宝贵的意见，我会进一步改进系统的用户界面，增加更多的功能模块，提高系统的稳定性和可扩展性。

总之，基于C++的机房预约系统是一项具有实际意义和应用前景的工作。通过不断优化和改进，该系统将在实际运行中发挥更大的作用，提高机房资源的利用率和管理效率。

代码实现：

用于定义身份的抽象类：identity.h

#pragma once
#include<iostream>
#include<string>
using namespace std;
class Identity {
public:
  string name;
  string pwd;
  virtual void operMenu() = 0;
};

继承它的子类：manager.h

#pragma once
#include<fstream>
#include"identity.h"
#include"student.h"
#include"teacher.h"
#include"computerroom.h"
#include"orders.h"
using namespace std;
class Manager : public Identity {
public:
  vector<Student> vStu;
  vector<Teacher> vTea;
  vector<ComputerRoom> vCom;
  Manager() = default;
  Manager(string name, string pwd);
  //菜单界面
  void operMenu();
  //添加账号
  void addPerson();
  //查看账号
  void showPerson();
  //查看机房信息
  void showComputer();
  //清空预约记录
  void cleanFile();
  //初始化容器
  void initVector();
  //检查是否重复
  bool isRepeat(int id, int type);
};
