功能描述:添加新账号时,如果是重复的学生编号,或是重复的教师职工编号,提示有误
void initVector()
初始化容器 //初始化容器
void initVector();
//学生容器
vector<Student> vStu;
//教师容器
vector<Teacher> vTea;
添加位置如图:
在Manager的有参构造函数中,获取目前的学生和教师信息
代码如下:
void Manager::initVector()
{
//读取学生文件中信息
ifstream ifs;
ifs.open(STUDENT_FILE, ios::in);
if (!ifs.is_open())
{
cout << "文件读取失败" << endl;
return;
}
vStu.clear();
vTea.clear();
Student s;
while (ifs >> s.m_Id && ifs >> s.m_Name && ifs >> s.m_Pwd)
{
vStu.push_back(s);
}
cout << "当前学生数量为: " << vStu.size() << endl;
ifs.close(); //学生初始化
//读取老师文件信息
ifs.open(TEACHER_FILE, ios::in);
Teacher t;
while (ifs >> t.m_EmpId && ifs >> t.m_Name && ifs >> t.m_Pwd)
{
vTea.push_back(t);
}
cout << "当前教师数量为: " << vTea.size() << endl;
ifs.close();
}
在有参构造函数中,调用初始化容器函数
//有参构造
Manager::Manager(string name, string pwd)
{
this->m_Name = name;
this->m_Pwd = pwd;
//初始化容器
this->initVector();
}
测试,运行代码可以看到测试代码获取当前学生和教师数量
在manager.h文件中添加成员函数 bool checkRepeat(int id, int type);
//检测重复 参数:(传入id,传入类型) 返回值:(true 代表有重复,false代表没有重复)
bool checkRepeat(int id, int type);
在manager.cpp文件中实现成员函数 bool checkRepeat(int id, int type);
bool Manager::checkRepeat(int id, int type)
{
if (type == 1)
{
for (vector<Student>::iterator it = vStu.begin(); it != vStu.end(); it++)
{
if (id == it->m_Id)
{
return true;
}
}
}
else
{
for (vector<Teacher>::iterator it = vTea.begin(); it != vTea.end(); it++)
{
if (id == it->m_EmpId)
{
return true;
}
}
}
return false;
}
在添加学生编号或者教师职工号时,检测是否有重复,代码如下:
string errorTip; //重复错误提示
if (select == 1)
{
fileName = STUDENT_FILE;
tip = "请输入学号: ";
errorTip = "学号重复,请重新输入";
}
else
{
fileName = TEACHER_FILE;
tip = "请输入职工编号:";
errorTip = "职工号重复,请重新输入";
}
ofs.open(fileName, ios::out | ios::app);
int id;
string name;
string pwd;
cout <<tip << endl;
while (true)
{
cin >> id;
bool ret = this->checkRepeat(id, 1);
if (ret) //有重复
{
cout << errorTip << endl;
}
else
{
break;
}
}
代码位置如图:
检测效果:
bug描述:
解决方案:
在添加完毕后,加入代码:
//初始化容器
this->initVector();
位置如图:
再次测试,刚加入的账号不会重复添加了!
功能描述:显示学生信息或教师信息
在Manager的showPerson成员函数中,实现显示账号功能,代码如下:
void printStudent(Student & s)
{
cout << "学号: " << s.m_Id << " 姓名: " << s.m_Name << " 密码:" << s.m_Pwd << endl;
}
void printTeacher(Teacher & t)
{
cout << "职工号: " << t.m_EmpId << " 姓名: " << t.m_Name << " 密码:" << t.m_Pwd << endl;
}
void Manager::showPerson()
{
cout << "请选择查看内容:" << endl;
cout << "1、查看所有学生" << endl;
cout << "2、查看所有老师" << endl;
int select = 0;
cin >> select;
if (select == 1)
{
cout << "所有学生信息如下: " << endl;
for_each(vStu.begin(), vStu.end(), printStudent);
}
else
{
cout << "所有老师信息如下: " << endl;
for_each(vTea.begin(), vTea.end(), printTeacher);
}
system("pause");
system("cls");
}
测试查看学生效果
测试查看教师效果
至此,显示账号功能实现完毕
案例需求中,机房一共有三个,其中1号机房容量20台机器,2号50台,3号100台
我们可以将信息录入到computerRoom.txt中
在头文件下,创建新的文件 computerRoom.h
并添加如下代码:
#pragma once
#include<iostream>
using namespace std;
//机房类
class ComputerRoom
{
public:
int m_ComId; //机房id号
int m_MaxNum; //机房最大容量
};
在Manager管理员类下,添加机房的容器,用于保存机房信息
//机房容器
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
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();
位置如图:
因为机房信息目前版本不会有所改动,如果后期有修改功能,最好封装到一个函数中,方便维护
在Manager类的showComputer成员函数中添加如下代码:
//查看机房信息
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");
}

ofstream ofs(ORDER_FILE, ios::trunc);
ofs.close();
cout << "清空成功!" << endl;
system("pause");
system("cls");
}
测试清空,可以随意写入一些信息在order.txt中,然后调用cleanFile清空文件接口,查看是否清空干净
//有参构造(学号、姓名、密码)
Student::Student(int id, string name, string pwd)
{
//初始化属性
this->m_Id = id;
this->m_Name = name;
this->m_Pwd = pwd;
}
添加全局函数 void studentMenu(Identity * &manager)
代码如下:
//学生菜单
void studentMenu(Identity * &student)
{
while (true)
{
//学生菜单
student->operMenu();
Student* stu = (Student*)student;
int select = 0;
cin >> select;
if (select == 1) //申请预约

}
else if (select == 2) //查看自身预约
{
stu->showMyOrder();
}
else if (select == 3) //查看所有预约
{
stu->showAllOrder();
}
else if (select == 4) //取消预约
{
stu->cancelOrder();
}
else
{
delete student;
cout << "注销成功" << endl;
system("pause");
system("cls");
return;
}
}
}
void Student::operMenu()
代码如下://菜单界面

更新预约记录的成员函数updateOrder代码如下:
void OrderFile::updateOrder()
{
if (this->m_Size == 0)
{
return;
}
ofstream ofs(ORDER_FILE, ios::out | ios::trunc);
for (int i = 0; i < m_Size;i++)
{
ofs << "date:" << this->m_orderData[i]["date"] << " ";
ofs << "interval:" << this->m_orderData[i]["interval"] << " ";
ofs << "stuId:" << this->m_orderData[i]["stuId"] << " ";
ofs << "stuName:" << this->m_orderData[i]["stuName"] << " ";
ofs << "roomId:" << this->m_orderData[i]["roomId"] << " ";
ofs << "status:" << this->m_orderData[i]["status"] << endl;
}
ofs.close();
}
首先我们先添加几条预约记录,可以用程序添加或者直接修改order.txt文件
order.txt文件内容如下: 比如我们有三名同学分别产生了3条预约记录
在Student类的void Student::showMyOrder()
成员函数中,添加如下代码
//查看我的预约
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++)
{
if (atoi(of.m_orderData[i]["stuId"].c_str()) == this->m_Id)
{
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";
}
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");
}
测试效果如图:
在Student类的void Student::showAllOrder()
成员函数中,添加如下代码
//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 << 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");
}
测试效果如图:
在Student类的void Student::cancelOrder()
成员函数中,添加如下代码
//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");
return;
}
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 (atoi(of.m_orderData[i]["stuId"].c_str()) == this->m_Id)
{
if (of.m_orderData[i]["status"] == "1" || of.m_orderData[i]["status"] == "2")
{
v.push_back(i);
cout << index ++ << "、 ";//后置++,先输出index本身的值,然后再加一
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";
}
else if (of.m_orderData[i]["status"] == "2")
{
status += "预约成功";
}
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
{
// cout << "记录所在位置: " << v[select - 1] << endl;
of.m_orderData[v[select - 1]]["status"] = "0";
of.updateOrder();
cout << "已取消预约" << endl;
break;
}
}
cout << "输入有误,请重新输入" << endl;
}
system("pause");
system("cls");
}
测试取消预约:
再次查看个人预约记录:
查看所有预约
查看order.txt预约文件
至此,学生模块功能全部实现
//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;
}
添加全局函数 void TeacherMenu(Person * &manager)
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;
}
}
}
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;
}
//进入教师子菜单
TeacherMenu(person);
添加效果如图:
测试对接,效果如图:
登录验证通过:
教师子菜单:
注销登录:
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");
}
运行测试教师身份的查看所有预约功能
测试效果如图:
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");
}
测试 - 审核通过
审核通过情况
测试-审核未通过
审核未通过情况:
学生身份下查看记录:
审核预约成功!
