某马机房预约系统 C++项目（二） 完结

8.4、查看机房

8.4.1、添加机房信息

根据案例，我们还是先在computerRoom.txt中直接添加点数据

//几机房  机器数量
1 20
2 50
3 100

8.4.2、机房类创建

​ 同样我们在头文件下新建一个computerRoom.h文件

添加如下代码：

#pragma once
#include<iostream>
using namespace std;

class ComputerRoom {
public:
	//机房id
	int m_ComId;
	//机房最大容量
	int m_MaxNum;
};

8.4.3、初始化机房信息并显示

在Manager管理类下，添加机房的容器，用于保存信息

//机房容器
#include "computerRoom.h"
vector<ComputerRoom> vCom;

在Manager有参构造函数中，追加如下代码，初始化机房信息

//获取机房信息
void Manager::getComputerNumber()
{
	// 文件名
	string computerFile = COMPUTER_FILE; // 替换为机房文件名

	ifstream  ifs;
	ifs.open(COMPUTER_FILE, ios::in);

	ComputerRoom c;

	while (ifs>>c.m_ComId && ifs>>c.m_MaxNum)
	{
		vCom.push_back(c);
	}

	cout << "当前机房数量为: " << vCom.size() << endl;

	ifs.close();
}

然后我们修改showComputer成员方法

void Manager::showComputer()
{
	cout << "机房信息如下： " << endl;
	for (vector<ComputerRoom>::iterator it = vCom.begin(); it != vCom.end();it++) {
		cout << "机房编号:" << it->m_ComId << " 机房最大容量:" << it->m_MaxNum << endl;
	}

	system("pause");
	system("cls");
}

效果图：

8.5、清空预约功能

接着我们来实现cleanFile成员方法

由于我们order文件中没有东西，如果需要测试可以自己添加一点

//清空预约系统
void Manager::clearFile()
{
	ofstream ofs(ORDER_FILE, ios::trunc);
	ofs.close();

	cout << "清空成功！" << endl;
	system("pause");
	system("cls");
}

9、学生模块

9.1、初始化信息

接下来我们对学生有参构造进行实现

student.cpp

//有参构造
Student::Student(int id, string name, string pwd)
{
	this->m_Id = id;
	this->m_Name = name;
	this->m_Pwd = pwd;
}

9.2、菜单实现

首先添加一个学生菜单函数，在机房预约系统.cpp中添加

void studentMenu(Indentity*& student);

然后我们来实现一下具体的步骤

void Student::studentMenu(Indentity*& student)
{
	while (true)
	{
		//学生菜单
		student->operMenu();
		Student* stu = (Student*)student;

		//接受用户选项
		int select = 0;
	
		cin >> select;
		switch (select)
		{
		case 1: //申请预约
			cout << "申请预约" << endl;
			stu->applyOrder();
			break;
		case 2://查看预约
			cout << "查看预约" << endl;
			stu->showMyOrder();
			break;
		case 3://查看所有预约
			cout << "查看所有预约" << endl;
			stu->showAllOrder();
			break;
		case 4://取消预约
			cout << "取消预约" << endl;
			stu->cancelOrder();
			break;
		default:
			//注销登录
		//销毁掉堆区对象
			delete student;
			cout << "注销成功" << endl;
			system("pause");
			system("cls");
			return;

		}
	}
}

接着我们来添加一下菜单，回到student.cpp

void Student::operMenu()
{
	cout << "欢迎：" << this->m_Name << "同学登录！" << endl;
	cout << endl;
	cout << "--------------       1、申请预约      -----------------" << endl;
	cout << endl;
	cout << "--------------       2、查看预约      -----------------" << endl;
	cout << endl;
	cout << "--------------       3、查看所有预约  -----------------" << endl;
	cout << endl;
	cout << "--------------       4、取消预约      -----------------" << endl;
	cout << endl;
	cout << "--------------    输入其他数字退出    -----------------" << endl;
	cout << "-------------------------------------------------------" << endl;
	cout << "请输入序号进行操作:";

}

然后回到机房预约系统.cpp

在这里添加方法，测试一下

9.3、申请预约实现

然后我们也要来获取一下机房信息，在studen.h中

#include"computerRoom.h"
#include "globalFile.h"
#include<fstream>
//机房信息
vector<ComputerRoom> vCom;

回到student.cpp中的学生构造中填一下以下代码

//有参构造
Student::Student(int id, string name, string pwd)
{
	this->m_Id = id;
	this->m_Name = name;
	this->m_Pwd = pwd;

	// 文件名
	string computerFile = COMPUTER_FILE; // 替换为机房文件名

	ifstream  ifs;
	ifs.open(COMPUTER_FILE, ios::in);

	ComputerRoom c;

	while (ifs >> c.m_ComId && ifs >> c.m_MaxNum)
	{
		vCom.push_back(c);
	}

	ifs.close();
}

然后我们来实现预约功能在applyOrder()中实现

void Student::applyOrder()
{
	cout << "机房开放时间为周一到周五!" << endl;
	cout << "请输入预约时间!" << endl;
	cout << "1、周一!" << endl;
	cout << "2、周二!" << endl;
	cout << "3、周三!" << endl;
	cout << "4、周四!" << endl;
	cout << "5、周五!" << endl;
	int date = 0;
	int interval = 0;
	int room = 0;

	while (true)
	{
		cin >> date;
		if (date>=1&&date<=5)
		{
			break;
		}
		cout << "输入有误，请重新输入" << endl;
	}

	cout << "请输入申请预约时间段" << endl;
	cout << "1、上午" << endl;
	cout << "2、下午" << endl;

	while (true)
	{
		cin >> interval;
		if (interval >= 1 && interval <= 2)
		{
			break;
		}
		cout << "输入有误，请重新输入" << endl;
	}

	cout << "请选择机房：" << endl;
	cout << "1号机房容量：" <<vCom[0].m_MaxNum << endl;
	cout << "2号机房容量：" << vCom[1].m_MaxNum << endl;
	cout << "3号机房容量：" << vCom[2].m_MaxNum << endl;

	while (true)
	{
		cin >> room;
		if (room>=1&&room<=3)
		{
			break;
		}
		cout << "输入有误，请重新输入" << endl;
	}

	cout << "预约成功！等待审核" << endl;

	ofstream ofs(ORDER_FILE, ios::app);
	ofs << "data:" << date << " ";
	ofs << "interval:" << interval << " ";
	ofs << "stuId:" << this->m_Id << " ";
	ofs << "stuName:" << this->m_Name << " ";
	ofs << "roomId:" << room << " ";
	ofs << "status:" << 1 << endl;;

	ofs.close();
	system("pause");
	system("cls");
}

9.4、显示预约

接着我们来创建一个预约类，用于获取所有记录和显示，以及更新

文件名为orderFile.h 和 orderFile.cpp文件

orderFile.h

#pragma once
#include<iostream>
#include<map>
#include "globalFile.h"
#include<string>
using namespace std;

class OrderFile {
public:

	//构造函数
	OrderFile();

	//更新预约记录
	void updateOrder();

	//记录容器 key 记录条数 value -- 具体记录的键值对
	map<int, map<string, string>>m_orderData;

	//记录预约的条数
	int m_size;
};

orderFile.cpp

OrderFile::OrderFile()
{
	ifstream ifs;
	ifs.open(ORDER_FILE, ios::in);

	string date; //日期
	string interval; //时间段
	string stuId; //学生编号
	string stuName; //学生姓名
	string roomId; //机房号
	string status; //预约状态

	this->m_size = 0; //记录条数

	while (ifs>>date && ifs >> interval&&
			ifs>>stuId&&ifs>>stuName&&ifs>>roomId
			&&ifs>>status)
	{
		map<string, string> m;
		insertInfo(m, date);
		insertInfo(m, interval);
		insertInfo(m, stuId);
		insertInfo(m, stuName);
		insertInfo(m, roomId);
		insertInfo(m, status);

		//将小mpa容器放到大的map容器中
		this->m_orderData.insert(make_pair(this->m_size, m));
		this->m_size++;
		//清空小容器
		m.clear();
	}
	ifs.close();
	//测试代码
	for (map<int, map<string, string>>::iterator it = m_orderData.begin(); it != m_orderData.end(); it++) {
		cout << "条数为：" << it->first << "value = " << endl;
		for (map<string, string>::iterator mit = (*it).second.begin(); mit != it->second.end(); mit++) {
			cout << "key = " << mit->first << " value = " << mit->second << " ";
		}
		cout << endl;
	}
}
//截取字符串
void OrderFile::insertInfo(map<string, string> &m,string keys) {
	string key;
	string value;
	int pos = keys.find(":");
	if (pos != -1)
	{
		key = keys.substr(0, pos);
		value = keys.substr(pos + 1);
		m.insert(make_pair(key, value));
	}
}

9.4.1、查看自身预约

student.cpp

void Student::showMyOrder()
{
	OrderFile of;
	if (of.m_size == 0) {
		cout << "无预约记录！" << endl;
		system("pause");
		system("cls");
		return;
	}

	for (int i = 0; i < of.m_size; i++) {
		//找到自身预约
		if (this->m_Id == stoi(of.m_orderData[i]["stuId"].c_str())) {
			cout << "预约的日期:周" << of.m_orderData[i]["date"];
			cout << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
			cout << " 机房号：" << of.m_orderData[i]["roomId"];
			string status = " 状态: ";
			//1.审核中 2.已预约 - 1 预约失败 0 取消预约
			if (of.m_orderData[i]["status"]=="1")
			{
				status += "审核中";
			}
			else if (of.m_orderData[i]["status"] == "2") {
				status += "预约成功";

			}
			else if (of.m_orderData[i]["status"] == "-1") {
				status += "预约失败,审核未通过";
			}else{
				status += "预约已经取消";
			}
			cout << status << endl;
		}
	}
	system("pause");
	system("cls");
}

9.4.2、显示所有预约

//查看所有预约
void Student::showAllOrder()
{
	OrderFile of;
	if (of.m_size == 0) {
		cout << "无预约记录！" << endl;
		system("pause");
		system("cls");
		return;
	}
	for (int i = 0; i < of.m_size; i++) {
		cout << "预约的日期:周" << of.m_orderData[i]["date"];
		cout << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
		cout << " 学号：" << of.m_orderData[i]["stuId"];
		cout << " 姓名：" << of.m_orderData[i]["stuName"];
		cout << " 机房号：" << of.m_orderData[i]["roomId"];
		string status = " 状态: ";
		//1.审核中 2.已预约 - 1 预约失败 0 取消预约
		if (of.m_orderData[i]["status"] == "1")
		{
			status += "审核中";
		}
		else if (of.m_orderData[i]["status"] == "2") {
			status += "预约成功";

		}
		else if (of.m_orderData[i]["status"] == "-1") {
			status += "预约失败,审核未通过";
		}
		else {
			status += "预约已经取消";
		}
		cout << status << endl;
	}
}

9.5、取消预约

student.cpp

//取消预约
void Student::cancelOrder()
{
	OrderFile of;
	if (of.m_size == 0)
	{
		cout << "无预约记录" << endl;
		system("pause");
		system("cls");
	}
	cout << "审核中或预约成功的记录可以取消，请输入取消的记录" << endl;
	vector<int> v;
	int index = 1;
	for (int i = 0; i< of.m_size; i++)
	{
		if (this->m_Id == stoi(of.m_orderData[i]["stuId"])) {
			//再筛选状态 审核中或预约成功的
			if (of.m_orderData[i]["status"]=="1"||of.m_orderData[i]["Status"]=="2")
			{
				v.push_back(i);
				cout << index++ << "、";
				cout << "预约的日期:周" << of.m_orderData[i]["date"];
				cout << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
				cout << " 机房号：" << of.m_orderData[i]["roomId"];
				string status = " 状态: ";
				//1.审核中 2.已预约 - 1 预约失败 0 取消预约
				if (of.m_orderData[i]["status"] == "1")
				{
					status += "审核中";
				}
				else if (of.m_orderData[i]["status"] == "2") {
					status += "预约成功";

				}
				else if (of.m_orderData[i]["status"] == "-1") {
					status += "预约失败,审核未通过";
				}
				else {
					status += "预约已经取消";
				}
				cout << status << endl;
			}
		}
	}

	cout << "请输入取消的记录，0代表返回" << endl;
	int select = 0;
	while (true)
	{
		cin >> select;
		if (select>=0 && select<=v.size())
		{
			if (select==0)
			{
				break;
			}
			else {
				of.m_orderData[v[select - 1]]["status"] = "0";
				of.updateOrder();
				cout << "已经取消预约" << endl;
				break;
			}

		}
		cout << "输入有误，请重新输入" << endl;
	}
	system("pause");
	system("cls");
}

10、教师模块

10.1、教师登录和注销

10.1.1、构造函数

• 在Teacher类的构造函数中，初始化教师信息，代码如下：

//有参构造
Teacher::Teacher(int empId, string name, string pwd)
{
	//初始化属性
	this->m_EmpId = empId;
	this->m_Name = name;
	this->m_Pwd = pwd;
}

10.1.2、教师子菜单

• 在机房预约系统.cpp中，当用户登录的是教师，添加教师菜单接口
• 将不同的分支提供出来
  • 查看所有预约
  • 审核预约
  • 注销登录
• 实现注销功能

首先我们还是回到机房预约系统.cpp中，创建一个teacherMenu方法,同样的在LoginIn中创建类并链接此方法

//老师子菜单界面
void teacherMenu(Indentity*& teacher)
{
	while (true)
	{
		//学生菜单
		teacher->operMenu();
		Teacher* tea = (Teacher*)teacher;

		//接受用户选项
		int select = 0;

		cin >> select;
		switch (select)
		{
		case 1: //查看所有预约
			cout << "查看所有预约" << endl;
			tea->showAllOrder();
			break;
		case 2://审核预约
			cout << "审核预约" << endl;
			tea->validOrder();
			break;
		default:
			//注销登录
		//销毁掉堆区对象
			delete teacher;
			cout << "注销成功" << endl;
			system("pause");
			system("cls");
			return;

		}
	}
}

teacher.cpp中 operMenu()

	cout << "欢迎：" << this->m_Name << "老师！" << endl;
	cout << endl;
	cout << "--------------       1、查看所有预约      -----------------" << endl;
	cout << endl;
	cout << "--------------       2、审核预约          -----------------" << endl;
	cout << endl;
	cout << "--------------      输入其他数字退出      -----------------" << endl;
	cout << "-------------------------------------------------------" << endl;
	cout << "请输入序号进行操作:";

10.1.2、审核预约

根据学生的申请进行审核

teacher.cpp

//审核预约
void Teacher::validOrder()
{
	OrderFile of;
	if (of.m_size == 0)
	{
		cout << "无预约记录" << endl;
		system("pause");
		system("cls");
	}
	cout << "审核中或预约成功的记录可以取消，请输入取消的记录" << endl;
	vector<int> v;
	int index = 1;
	for (int i = 0; i < of.m_size; i++)
	{
			//再筛选状态 审核中或预约成功的
			if (of.m_orderData[i]["status"] == "1")
			{
				v.push_back(i);
				cout << index++ << "、";
				cout << "预约的日期:周" << of.m_orderData[i]["date"];
				cout << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
				cout << " 机房号：" << of.m_orderData[i]["roomId"];
				string status = " 状态: ";
				//1.审核中 2.已预约 - 1 预约失败 0 取消预约
				if (of.m_orderData[i]["status"] == "1")
				{
					status += "审核中";
				}

				cout << status << endl;		
			}
	}
	cout << "请输入审核的预约记录，0代表返回" << endl;
	int select = 0;
	int ret = 0;
	while (true)
	{
		cin >> select;
		if (select >= 0 && select <= v.size())
		{
			if (select == 0)
			{
				break;
			}
			else {
				cout << "请输入审核结果" << endl;
				cout << "1.通过" << endl;
				cout << "2.不通过" << endl;
				cin >> ret;
				
				if (ret == 1)
				{
					of.m_orderData[v[select - 1]]["status"] = "2";
				}
				else {
					of.m_orderData[v[select - 1]]["status"] = "-1";
				}
				of.updateOrder();
				cout << "审核完毕!" << endl;
				break;
			}
		}
		cout << "输入有误，请重新输入" << endl;
	}
	system("pause");
	system("cls");
}
