再系统地过一次,夯实基础
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、教师创建账号机房总共有三件
1号机房 — 最大容量20人2号机房 — 最大容量50人3号机房 — 最大容量100人功能描述:
设计主要菜单,与用户进行交互在main函数分支0选项中,添加退出程序代码:
case 0://退出系统 cout << "欢迎下一次使用" << endl; system("pause"); return 0; break;功能描述:
不同的身份可能会用到不同的文件操作,我们可以将所有的文件名定义到一个全局的文件中在头文件中添加 globalFile.h 文件并添加如下代码: #pragma once //管理员文件 constexpr auto ADMIN_FILE = "admin.txt"; //学生文件 constexpr auto STUDENT_FILE = "student.txt"; //教师文件 constexpr auto TEACHER_FILE = "teacher.txt"; //机房信息文件 constexpr auto COMPUTER_FILE = "computerRoom.txt"; //订单文件 constexpr auto ORDER_FILE = "order.txt";并在同级目录下创建相关.txt文件
功能描述:
根据用户的选择,进入不同的身份登录在预约系统的.cpp文件中添加全局函数 void LoginIn(string fileName, int type) 参数:
fileName — 操作的文件名type — 登录的身份 (1代表学生、 2代表老师、 3代表管理员) #include <iostream> #include "globalFile.h" #include "Identity.h" #include <fstream> #include <string> using namespace std; //登录功能 参数1 操作文件名 参数2 操作身份类型 void LoginIn(string fileName, int type) { //父类指针 用于指向子类对象 Identity* person = nullptr; //读文件 ifstream ifs; ifs.open(fileName, ios::in); //判断文件是否存在 if (!ifs.is_open()) { cout << "文件不存在" << endl; ifs.close(); return; } //准备接受用户信息 int id = 0; string name; string pwd; //判断身份 if (type == 1) { //学生身份 cout << "请输入您的学号:" << endl; cin >> id; } else if (type == 2) { cout << "请输入您的职工号:" << endl; cin >> id; } cout << "请输入用户名:" << endl; cin >> name; cout << "请输入密码:" << endl; cin >> pwd; if (type == 1) { //学生身份验证 } else if (type == 2) { //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"); return; } int main() { int select = 0; while (true) { cout << endl << "请输入您的身份" << endl; cout << "\t\t ---------------------------------\n"; cout << "\t\t | |\n"; cout << "\t\t | 1.学生代表 |\n"; cout << "\t\t | |\n"; cout << "\t\t | 2.老 师 |\n"; cout << "\t\t | |\n"; cout << "\t\t | 3.管 理 员 |\n"; cout << "\t\t | |\n"; cout << "\t\t | 0.退 出 |\n"; cout << "\t\t | |\n"; cout << "\t\t ---------------------------------\n"; cout << "请输入您的选择:"; cin >> select;//接受用户选择 switch (select) { 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; case 0://退出系统 cout << "欢迎下一次使用" << endl; system("pause"); return 0; break; default: cout << "输入有误,请重新选择!" << endl; system("pause"); system("cls"); break; } } system("pause"); system("cls"); return 0; }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:
第一列代表 学号第二列代表 学生姓名第三列代表 密码在LoginIn函数的学生分支中加入如下代码,验证学生身份
if (type == 1) { //学生身份验证 int fId; string fName; string fPwd; while (ifs >> fId && ifs >> fName && ifs >> fPwd) { //与用户输入的信息做对比 if (id == fId && name == fName && pwd == fPwd) { cout << "学生验证登录成功!" << endl; system("pause"); system("cls"); person = new Student(id, name, pwd); //进入学生身份的子菜单 return; } } }在teacher.txt文件中添加一条老师信息,用于测试
添加信息
1 laowang 123在LoginIn函数的教师分支中添加如下代码,验证身份
else if (type == 2) { //教师身份验证 int fId; string fName; string fPwd; while (ifs >> fId && ifs >> fName && ifs >> fPwd) { //与用户输入的信息做对比 if (id == fId && name == fName && pwd == fPwd) { cout << "教师验证登录成功!" << endl; system("pause"); system("cls"); person = new Teacher(id, name, pwd); //进入老师身份的子菜单 return; } } }在admin.txt文件中添加一条管理员信息,由于只有一条管理员,因此没有添加管理员的功能
admin 123在LoginIn函数的管理员分支中添加如下代码,验证身份
else if (type == 3) { //管理员身份验证 string fName; string fPwd; while (ifs >> fName && ifs >> fPwd) { //与用户输入的信息做对比 if (name == fName && pwd == fPwd) { cout << "管理员验证登录成功!" << endl; system("pause"); system("cls"); person = new Manager(name, pwd); //进入管理员身份的子菜单 return; } } }添加全局函数 void managerMenu(Identity*& manager)
//进入管理员子菜单界面 void managerMenu(Identity*& manager) { while (true) { //调用管理员子菜单 manager->operMenu(); //将父类指针 转为子类指针,调用子类里其他接口 Manager* man = (Manager*)manager; int select = 0; //接受用户的选项 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) { //查看机房信息 cout << "查看机房" << endl; man->showComputer(); } else if (select == 4) { //清空预约 cout << "清空预约" << endl; man->cleanFile(); } else { delete manager;//销毁堆区对象 cout << "注销成功" << endl; system("pause"); system("cls"); return; } } }功能描述:
给学生或教师添加新的账号功能要求:
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
void Manager::addPerson() { cout << "请输入添加账号的类型" << endl; cout << "1、添加学生" << endl; cout << "2、添加老师" << endl; string fileName;//操作的文件名 string tip;//提示id号 ofstream ofs;//文件操作对象 int select = 0; cin >> select;//接受用户的选项 if (select == 1) { //添加的是学生 fileName = STUDENT_FILE; tip = "请输入学号:"; } else { fileName = TEACHER_FILE; tip = "请输入职工编号:"; } //利用追加的方式 写文件 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; //向文件中添加数据 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,或是重复的教师职工编号,提示有误
在Manager.cpp中实现
void Manager::initVector() { //确保容器清空状态 vStu.clear(); vTea.clear(); //读取学生信息 ifstream ifs; ifs.open(STUDENT_FILE, ios::in); if (!ifs.is_open()) { cout << "文件读取失败" << endl; return; } Student s; while (ifs >> s.m_Id && ifs >> s.m_Name && ifs >> s.m_Pwd) { vStu.push_back(s); } //测试 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 << "文件读取失败" << endl; return; } Teacher t; while (ifs >> t.EmpId && ifs >> t.m_Name && ifs >> t.m_Pwd) { vTea.push_back(t); } //测试 cout << "当前老师数量为:" << vTea.size() << endl; ifs.close(); }在有参构造函数中,调用初始化容器函数
Manager::Manager(string name, string pwd) { this->m_Name = name; this->m_Pwd = pwd; //初始化容器 this->initVector(); }在manager.h文件中添加成员函数 bool checkRepeat(int id, int type);
//检查重复 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中实现
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; }在添加学生学号或教师职工号时,检测是否有重复
if (select == 1) { //添加的是学生 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 = "学号重复,请重新输入"; } //利用追加的方式 写文件 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, select); if (ret)//有重复 cout << errorTip << endl; else break; }bug描述:
虽然可以检测重复的账号,但是刚添加的账号由于没有更新到容器中,因此不会做检测导致刚加入的账号的学生号或者职工编号,再次添加时依然可以重复解决方案:
在每次添加新账号时,重新初始化容器在添加完毕后,加入init代码:
//向文件中添加数据 ofs << id << " " << name << " " << pwd << " " << endl; cout << "添加成功" << endl; system("pause"); system("cls"); ofs.close(); //初始化容器 this->initVector();在Manager的showPerson成员函数中,实现显示账号功能
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 << "学号:" << t.m_EmpId << " 姓名:" << t.m_Name << " 密码:" << t.m_Pwd << endl; } //查看账号 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 << "学号:" << 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、查看所有的学生" << endl; cout << "2、查看所有的老师" << endl; int select = 0;//接受用户选择 cin >> select; if (select == 1) { //查看学生 cout << "所有学生信息如下:" << endl; for_each(vStu.begin(), vStu.end(), printStudent); } else { //查看老师 cout << "所有老师信息如下:" << endl; for_each(vTea.begin(), vTea.end(), printTeacher); } system("pause"); system("cls"); }案例需求中,机房一共有三个,其中1号机房容量20,二号50,三号100台 将信息录入到computerRoom.txt中
在头文件下,创建新的文件 computerRoom.h
#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,追加代码,初始化机房信息
Manager::Manager(string name, string pwd) { this->m_Name = name; this->m_Pwd = pwd; //初始化容器 this->initVector(); //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(); }在Manager类的showComputer成员函数中添加如下代码
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"); }功能描述: 清空生成的 order.txt 预约文件
在manager的clean成员函数中添加如下代码:
void Manager::cleanFile() { ofstream ofs(ORDER_FILE, ios::trunc); ofs.close(); cout << "清空成功!" << endl; system("pause"); system("cls"); }添加main全局函数 void studentMenu(Identity*& student)
//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 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 << "注销成功" << endl; system("pause"); system("cls"); return; } } }在学生的有参构造函数中追加代码:
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; //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(); }在student.cpp中实现成员函数 void Student::applyOrder()
void Student::applyOrder() { cout << "机房开放时间为周一至周五" << endl; cout << "请输入申请预约的时间:" << 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"; } cout << "请输入申请预约的时间段:" << 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!审核中" << endl; ofstream ofs(ORDER_FILE, ios::app); ofs << "date:" << 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"); }功能描述:显示预约记录时,需要从文件中获取到所有记录,用来显示,创建预约的类来管理记录以及更新
在头文件以及源文件下分别创建orderFile.h和orderFile.cpp文件 orderFile.h添加代码:
#pragma once #include <iostream> using namespace std; #include <map> #include "globalFile.h" class OrderFile { public: //构造函数 OrderFile(); //更新预约记录 void updateOrder(); //记录的容器 key --- 记录的条数 value ---具体记录的键值对信息 map<int, map<string, string>> m_orderData; //预约记录条数 };构造函数中获取所有信息,并存放在容器中,添加如下代码:
