{
//教师身份验证
}
else if (type == 3)
{
//管理员身份验证
}
cout << "验证登录失败!" << endl;
system("pause");
system("cls");
}
在mian函数不同分支中,填入不同的登录接口参数
case 1: // 学生身份
loginIn(STUDENT_FILE, 1);
break;
case 2: // 老师身份
loginIn(TEACHER_FILE, 2);
break;
case 3: // 管理员身份
loginIn(ADMIN_FILE, 3);
break;
在student.txt文件中添加两条学生信息,用于测试
添加信息:
1 张三 123
2 李四 123456
其中:
//学生身份验证
int fId;//从文件中读取的id
string fName;//从文件中获取的姓名
string fPwd;//从文件中读取的密码
while (ifs >> fId && ifs >> fName && ifs >> fPwd)
{
//与用户输入的信息做对比
if (fId == id && fName == name && fPwd == pwd)
{
cout << "学生验证登录成功!" << endl;
system("pause");
system("cls");
person = new Student(id, name, pwd);
//进入到学生身份的子菜单
return;
}
}
测试验证:
在teacher.txt中添加一条老师信息用于测试
添加信息:
1 张老师 123
其中:
int fId;
string fName;
string fPwd;
while (ifs >> fId && ifs >> fName && ifs >> fPwd)
{
if (fId == id && fName == name && fPwd == pwd)
{
cout << "教师验证登录成功!" << endl;
system("pause");
system("cls");
person = new Teacher(id, name, pwd);
//进入教师的子菜单界面
return;
}
}
在admin.txt中添加一条管理员信息,由于我们只有一条管理员,因此本案例中乜有添加管理员信息功能
添加信息:
1 admin 123
其中:admin代表管理员用户名,123代表管理员密码
效果图:
在loginIn函数的管理员分支中加入如下代码,验证管理员身份
int fId;
string fName;
string fPwd;
while (ifs >> fName && ifs >> fPwd)
{
if (fName == name && fPwd == pwd)
{
cout << "管理员验证登录成功!" << endl;
system("pause");
system("cls");
person = new Manager(name, pwd);
//进入管理员的子菜单界面
return;
}
}
//有参构造(管理员姓名、密码)
Manager::Manager(string name, string pwd)
{
this->m_Name = name;
this->m_Pwd = pwd;
}
//进入管理员子菜单页面
void ManagerMenu(Identity*& manager)
{
while (true)
{
//调用管理员子菜单
manager->openMenu();
//将父类的指针转为子类的指针,调用子类的其他特有接口
Manager* man = (Manager*) manager;
int select = 0;
//接收用户的选项
cin >> select;
if (select == 1)//添加账号
{
cout << "添加账号!" << endl;
man->addPerson();
}
else if (select == 2)//查看账号
{
cout << "查看账号!" << endl;
man->showPerson();
}
else if (select == 3)//查看机房
{
cout << "查看机房!" << endl;
man->showCompter();
}
else if (select == 4)//清空预约
{
cout << "清空预约!" << endl;
man->cleanFile();
}
else
{
delete manager;//销毁掉堆区的对象
cout << "注销成功!" << endl;
system("pause");
system("cls");
}
}
}
//选择菜单
void Manager::openMenu()
{
cout << "=== 欢迎管理员:" << this->m_Name <<"===登录 " << endl;
cout << endl << "请输入您的身份" << endl;
cout << "\t\t ------------------------------\n";

cout << "\t\t | |\n";
cout << "\t\t ------------------------------\n";
cout << "请选择您的操作:";
}
功能描述:
给学生或者教师添加账号
工能要求
添加时学生学号不能重复,教师职工号不能重复
在Manager的addPerson成员函数中,实现添加新账号功能,代码如下:
//添加账号
void Manager::addPerson()
{
cout << "请输入添加账号类型:" << endl;
cout << "1、添加学生" << endl;
cout << "2、添加教师" << endl;
string fileName;
string tip;
ofstream ofs;
int select = 0;
cin >> select;
if (select == 1)
{
fileName = STUDENT_FILE;
tip = "请输入学号";
}
else
{
fileName = TEACHER_FILE;
tip = "请输入职工号";
}
ofs.open(fileName, ios::out | ios::app);
int id;
string name;
string pwd;
cout << tip << endl;
cin >> id;
cout << "请输入姓名:" << endl;
cin >> name;
cout << "请输入密码:" << endl;
cin >> pwd;
ofs << id << " " << name << " " << pwd << " " << endl;
cout << "添加成功!" << endl;
system("pause");
system("cls");
ofs.close();
}
功能描述:添加新账号时,如果是重复的学生编号,或者是重复的教职工编号,提示有误
//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的有参构造中获取目前的学生和教师信息
代码如下:
//初始化容器
void Manager::initVector()
{
//确保容器为清空状态
vStu.clear();
vTea.clear();
//读取信息,学生和老师
ifstream ifs;
ifs.open(STUDENT_FILE, ios::in);
if (!ifs.is_open())
{
cout << "学生文件读取失败!" << endl;
return;
}
//读取学生信息
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();
//读取老师信息
ifs.open(TEACHER_FILE, ios::in);
if (!ifs.is_open())
{
cout << "教师文件读取失败!" << endl;
return;
}
Teacher t;
while (ifs >> t.m_EmpId && ifs >> t.m_Name && ifs >> t.m_Pwd)
{
vTea.push_back(t);
}
cout << "当前老师数量为:" << vTea.size() << endl;
ifs.close();
}
在有参构造中,调用初始化容器函数
//有参构造(管理员姓名、密码)
Manager::Manager(string name, string pwd)
{
this->m_Name = name;
this->m_Pwd = pwd;
//初始化容器,并获取到所有文件中的学生、老师
this->initVector();
}
测试,运行代码可以看到测试代码获取当前文件中的学生和教师数量
在manager.h中添加成员函数bool checkRepeat(int id,int type);
//检测去重,true代表重复,false代表不重复
bool checkRepeat(int id, int type);
在manager.cpp中是吸纳成员函数bool checkRepeat(int id,int type);
//检测去重,true代表重复,false代表不重复
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;
}
在添加学生或者教职工是,检测是否有重复,代码如下
string errorTip;//重复错误提示信息
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;
}
}
bug描述:
在添加完毕后,加入代码:
//舒适化容器
this->initVector();
功能描述:
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;
}
//查看账号
void Manager::showPerson()
{
cout << "请选择查看内容:" << endl;
cout << "1、查看所有学生" << endl;
cout << "2、查看所有教师" << endl;
int select = 0;
cin >> select;
if (select == 1)
{
cout << "所有学生信息显示如下:" << endl;
for_each(vStu.begin(), vStu.end(), printStudent);
}
else
{
cout << "所有教师信息显示如下:" << endl;
for_each(vTea.begin(), vTea.end(), printTeacher);
}
system("pause");
system("cls");
}
案例需求中,机房总共有三个,其中一号机房容量20台机器,2号50台,3号100台
我们可以将信息记录到computerRoom.txt中
在头文件下创建新的文件:computerRoom.h
并添加如下代码:
///@brief computerRoom.h 机房信息类
///@date 2022-12-13
///@author zhichengMa
/
#pragma once
#include
using namespace std;
#include
#include
#include "identity.h"
//机房类
class ComputerRoom
{
public:
int m_ComId;//机房编号
int m_MaxNum;//机房最大容量
};
存在Manager管理类下,添加机房的容器,用户保存机房信息
//机房容器
vector<ComputerRoom> vCom;
在Manager的有参构造中,追加如下代码,初始化机房信息
//初始化容器,并获取到所有文件中的学生、老师
this->initVector();
//获取机房信息
ifstream ifs;
ifs.open(COMPUTER_FILE, ios::in);
ComputerRoom c;
while (ifs >> c.m_ComId && c.m_MaxNum)
{
vCom.push_back(c);
}
cout << "当前机房数量为:" << vCom.size() << endl;
ifs.close();
在Manager类的showComputer成员函数中添加如下代码:
//查看机房信息
void Manager::showCompter()
{
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 << " \t机房最大容量:" << it->m_MaxNum << endl;
}
system("pause");
system("cls");
}
功能描述:
清空生成的order.txt预约文件
在Manager的cleanFile成员函数中添加代码:
//清空预约记录
void Manager::cleanFile()
{
ofstream ofs(ORDER_FILE, ios::trunc);
ofs.close();
cout << "预约清空成功!";
system("pause");
system("cls");
}
测试清空,可以随意写一写信息到order.txt中,然后调用cleanFIle后查看文件是否清空干净
//有参构造
Student::Student(int id, string name, string pwd)
{
this->m_Id = id;
this->m_Name = name;
this->m_Pwd = pwd;
}
添加全局函数 void studentMenu(Identy * &manager)代码如下:
//学生子菜单
void studentMenu(Identity*& student)
{
//学生菜单
student->openMenu();
Student* stu = (Student*)student;
int select = 0;
cin >> select;
if (select == 1)//申请预约
{
stu->applyOrder();
}
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 << "学生注销成功!" << endl;
system("pause");
system("cls");
return;
}
}
//菜单界面
void Student::openMenu()
{
cout << "=== 欢迎学生代表:" << this->m_Name << "===登录 " << endl;
cout << endl << "请输入您的身份" << endl;
cout << "\t\t ------------------------------\n";
cout << "\t\t | |\n";
cout << "\t\t |-------- 1、申请预约-------- |\n";
cout << "\t\t | |\n";
cout << "\t\t |------ 2、查看我的预约 ----- |\n";
cout << "\t\t | |\n";
cout << "\t\t |------- 3、查看所有预约 ------ |\n";
cout << "\t\t | |\n";
cout << "\t\t |-------- 4、取消预约 ------- |\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:";
}
//进入到学生身份的子菜单
studentMenu(person);
//机房容器
vector<ComputerRoom> vCom;
在学生的有参构造中追加如下代码:
//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);
}
ifs.close();
代码位置如图:
在student.cpp中实现成员函数 void Student::applyOrder()
//申请预约
void Student::applyOrder()
{
cout << "机房开放时间一般为周一至周五!" << endl;
cout << "请输入预约的时间:" << 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 << "请输入预约的时间段:" << endl;
cout << "1、上午" << endl;
cout << "2、下午" << endl;
while (true)
{

cout << "3号机房容量" << vCom[2].m_MaxNum << endl;
while (true)
{
cin >> room;
if (room >= 1 && room <= 3)
{
break;
}
cout << "输入机房信息有误,请重新输入!" << endl;
}
cout << "预约成功,审核中!" << endl;
ofstream ofs(ORDER_FILE, ios::app);
ofs << "date:" << date << " ";

ofs << "stuId:" << this->m_Id << " ";
ofs << "stuName:" << this->m_Name << " ";
ofs << "roomId:" << room << " ";
ofs << "status:" << 1 << " ";// 1-审核中
}
功能描述:
显示预约记录时,需要从文件中获取所有记录用于显示,创建预约类来管理记录以及更新记录
在头文件基于稳健下分别创建orderFile.h 和orderFile.cpp 文件
orderFile.h中添加如下代码
///@brief orderFile.h 预约类

更新预约记录的成员函数updateOrder代码如下:
//更新预约记录
void OrderFile::uodateOrder()
{
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"] << " ";
}
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:
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-取消预约,1-审核中,2-已预约,3-预约失败
if (of.m_orderData[i]["status"] == "1") {
status += "审核中";
}
else if (of.m_orderData[i]["status"] == "2")
{
status += "已预约";
}
else if (of.m_orderData[i]["status"] == "3")
{
status += "审核为未通过,预约失败";
}
else
{
status += "预约已取消";
}
cout << status << endl;
}
}
system("pause");
system("cls");
}
在Student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 << "\t";
cout << "预约日期:周" << of.m_orderData[i]["date"] << "\t";
cout << "时段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午") << "\t";
cout << "学号:" << of.m_orderData[i]["stuId"] << "\t";
cout << "姓名:" << of.m_orderData[i]["stuName"] << "\t";
cout << "机房:" << of.m_orderData[i]["roomId"] << "\t";
string status = "状态:";//0-取消预约,1-审核中,2-已预约,3-预约失败
if (of.m_orderData[i]["status"] == "1") {
status += "审核中";
}
else if (of.m_orderData[i]["status"] == "2")
{
status += "已预约";
}
else if (of.m_orderData[i]["status"] == "3")
{
status += "审核为未通过,预约失败";
}
else
{
status += "预约已取消";
}
cout << status << endl;
}
system("pause");
system("cls");
}
在Student类的void Student::cancleOrder()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 << "审核中或者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 == atoi(of.m_orderData[i]["stuId"].c_str()))
{
if (of.m_orderData[i]["status"] == "1" || of.m_orderData[i]["status"] == "2")
{
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-取消预约,1-审核中,2-已预约,3-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表示返回" << endl;
int select = 0;
while (true)
{
cin >> select;
if (select >= 0 && select <= v.size())
{
if (select == 0)
{
break;
}
else
{
of.m_orderData[select - 1]["status"] = "0";
of.uodateOrder();
cout << "已取消预约";
break;
}
}
cout << "输入有误,请重新输入" << endl;
}
system("pause");
system("cls");
}
//有参构造(职工编号,姓名,密码)
Teacher::Teacher(int empId, string name, string pwd)
{
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:
//教师子菜单
void TeacherMenu(Identity*& teacher)
{
while (true)
{
//教师菜单
teacher->openMenu();
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;
}
}
}
//菜单界面
void Teacher::openMenu()
{
cout << "=== 欢迎教师:" << this->m_Name << "===登录 " << endl;
cout << endl << "请输入您的操作" << 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:";
}
//进入教师的子菜单界面
TeacherMenu(person);
该功能与学生身份的查看所有预约相似,用于显示所有的预约记录
在Teacher.cpp中实现成员函数void Teacher::showAllOrder()
//查看所有预约
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 << "\t";
cout << "预约日期:周" << of.m_orderData[i]["date"] << "\t";
cout << "时段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午") << "\t";
cout << "学号:" << of.m_orderData[i]["stuId"] << "\t";
cout << "姓名:" << of.m_orderData[i]["stuName"] << "\t";
cout << "机房:" << of.m_orderData[i]["roomId"] << "\t";
string status = "状态:";//0-取消预约,1-审核中,2-已预约,3-预约失败
if (of.m_orderData[i]["status"] == "1") {
status += "审核中";
}
else if (of.m_orderData[i]["status"] == "2")
{
status += "已预约";
}
else if (of.m_orderData[i]["status"] == "3")
{
status += "审核为未通过,预约失败";
}
else
{
status += "预约已取消";
}
cout << status << endl;
}
system("pause");
system("cls");
}
功能描述:
教师审核学生的粤语,依据实际情况审核
在Teacherl.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 << "待审批预约记录如下:" << 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"] << "\t";
cout << "时段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午") << "\t";
cout << "学号:" << of.m_orderData[i]["stuId"] << "\t";
cout << "姓名:" << of.m_orderData[i]["stuName"] << "\t";
cout << "机房:" << of.m_orderData[i]["roomId"] << "\t";
string status = "状态:";//0-取消预约,1-审核中,2-已预约,3-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) {
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.uodateOrder();
cout << "审核完毕!" << endl;
break;
}
cout << "输入有误,请重新输入" << endl;
}
system("pause");
system("cls");
}
创建文件夹MachinRoom,并在文件夹中创建lib、include、src
g++ -c -fpic teacher.cpp student.cpp orderFile.cpp manager.cpp
g++ -shared teacher.o student.o orderFile.o manager.o -o libmachine_room.so
3. 将生成的动态库文件libmachine_room.so放到lib目录下
g++ MachineRoomReservation.cpp -o main -I ./include/ -L lib -l machine_room
./main
