机房预约系统 C++

机房预约系统

1、系统简介

学校现有几个规格不同的机房，由于使用时经常出现“撞车”现象，现开发一套机房预约系统，解决这一问题。

2、身份简介：

• 学生代表：申请使用机房
• 教师：审核学生的预约申请
• 管理员：给学生、教师创建账号

3、机房简介

机房一共有3间：

• 1号机房——最大容量20人
• 2号机房——最大容量50人
• 3号机房——最大容量100人

4、申请简介

• 申请的订单每周由管理员负责清空
• 学生可以预约未来一周内的机房使用，预约的日期为周一至周五，预约时需要选择预约时段（上午、下午)
• 教师来审核预约，根据实际情况审核通过或者不通过

5、系统具体需求

首先进入登录界面，可选登录身份有：

• 学生代表
• 老师
• 管理员
• 退出

每个身份都需要进行验证后，进入子菜单

• 学生需要输入：学号、姓名、登录密码
• 老师需要输入：职工号、姓名、登录密码
• 管理员需要输入：管理员姓名、登录密码

学生具体功能

• 申请预约——预约机房
• 查看自身的预约——查看自己的预约状态
• 查看所有预约——查看全部预约信息以及预约状态
• 取消预约—— 取消自身的预约，预约成功或审核中的预约均可取消

教师具体功能

• 查看所有预约——查看全部预约信息以及预约状态
• 审核预约——对学生的预约进行审核
• 注销登录——退出登录

管理员具体功能

• 添加账号——添加学生或教师的账号，需要检测学生编号或教师职工号是否重复
• 查看账号——可以选择查看学生或教师的全部信息
• 查看机房——查看所有机房的信息
• 清空预约——清空所有预约记录
• 注销登录——退出登录

---

在文本文件中添加机房信息（房间号和最大容量）和管理员信息（姓名和登录密码），

老师和学生的账号可以通过登录管理员，选择添加账号进行添加，也可直接在文本文件中添加。
