简单的C++项目之机房预约系统（五）

教师模块

1 教师登录和注销

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 (职工编号，姓名，密码)
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;
}

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

添加全局函数 void TeacherMenu(Person * &teacher) 代码如下：

//教师菜单
void TeacherMenu(Identity * &teacher)
{
     
	while (true)
	{
     
		//教师菜单
		teacher->operMenu();

		Teacher* tea = (Teacher*)teacher;
		int select = 0;

		cin >> select;

		if (select == 1)
		{
     
			//查看所有预约
			tea->showAllOrder();
		}
		else if (select == 2)
		{
     
			//审核预约
			tea->validOrder();
		}
		else
		{
     
			delete teacher;
			cout << "注销成功" << endl;
			system("pause");
			system("cls");
			return;
		}

	}
}

1.3 菜单功能实现

• 在实现成员函数void Teacher::operMenu() 代码如下：

//教师菜单界面
void Teacher::operMenu()
{
     
	cout << "欢迎教师：" << this->m_Name << "登录！" << endl;
	cout << "\t\t ----------------------------------\n";
	cout << "\t\t|                                  |\n";
	cout << "\t\t|          1.查看所有预约          |\n";
	cout << "\t\t|                                  |\n";
	cout << "\t\t|          2.审核预约              |\n";
	cout << "\t\t|                                  |\n";
	cout << "\t\t|          0.注销登录              |\n";
	cout << "\t\t|                                  |\n";
	cout << "\t\t ----------------------------------\n";
	cout << "请选择您的操作： " << endl;
}

1.4 接口对接

• 教师成功登录后，调用教师的子菜单界面
• 在教师登录分支中，添加代码：

//进入教师子菜单
TeacherMenu(person);

2 查看所有预约

该功能与学生身份的查看所有预约功能相似，用于显示所有预约记录
在Teacher.cpp中实现成员函数 void Teacher::showAllOrder()

void Teacher::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 << i + 1 << "、 ";

		cout << "预约日期： 周" << of.m_orderData[i]["date"];
		cout << " 时段：" << (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：" << of.m_orderData[i]["roomId"];
		string status = " 状态： ";  // 0 取消的预约   1 审核中   2 已预约 -1 预约失败
		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 += "审核未通过，预约失败";
		}
		else
		{
     
			status += "预约已取消";
		}
		cout << status << endl;
	}

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

3 审核预约

功能描述：教师审核学生的预约，依据实际情况审核预约
在Teacher.cpp中实现成员函数 void Teacher::validOrder()
代码如下：

//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");
		return;
	}
	cout << "待审核的预约记录如下：" << endl;

	vector<int>v;
	int index = 0;
	for (int i = 0; i < of.m_Size; i++)
	{
     
		if (of.m_orderData[i]["status"] == "1")
		{
     
			v.push_back(i);
			cout << ++index << "、 ";
			cout << "预约日期： 周" << of.m_orderData[i]["date"];
			cout << " 时段：" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
			cout << " 机房：" << of.m_orderData[i]["roomId"];
			string status = " 状态： ";  // 0取消的预约   1 审核中   2 已预约  -1 预约失败
			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");
}
