【机房预约系统(C++版)】

一、机房预约系统需求

1.1、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。

1.2、身份简介

分别有三种身份使用该程序
·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

1.3、机房简介

机房总共有3间
·1号机房 --- 最大容量20人
·2号机房 --- 最多容量50人
·3号机房 --- 最多容量100人

1.4、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，依据实际情况审核预约通过或者不通过

1.5、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

二、分模块代码

2.1、identity身份基类

#pragma once
using namespace std;
#include
#include "globalFile.h"

//身份抽象基类
class Identity
{
public:
	//用户名
	string m_Name;

	//密码
	string m_Pwd;

	//纯虚函数 - 操作函数
	virtual void operMenu() = 0;
};

2.2、manager管理员

	//查看账号
	void showPerson();

	//查看机房信息
