bool insertappointment(const int& date):尝试租借小会议室,如果租借成功返回tru

一个结课级别的C++项目,模拟学校机房的运行和管理。

项目需求如下：

使用者身份

机房简介

申请规则

系统按身份登录，每个身份通过账号密码的验证之后进入子菜单：

1. 学生菜单

2. 教师菜单

3. 管理员菜单

1. 主页面

  1. int main() {
  2. 	while (true)
  3. 	{
  4. 		int select = 0;
  5. 		cout << "================== Welcome to Computer Room Reserving System ==================" << endl;
  6. 		cout << endl << "Please Enter Your Identity" << endl; 
  7. 		cout << "\t\t ----------------------------------------------\n";
  8. 		cout << "\t\t|                                             |\n";
  9. 		cout << "\t\t|                 1. Student                  |\n";
  10. 		cout << "\t\t|                                             |\n";
  11. 		cout << "\t\t|                                             |\n";
  12. 		cout << "\t\t|                 2. Teacher                  |\n";
  13. 		cout << "\t\t|                                             |\n";
  14. 		cout << "\t\t|                                             |\n";
  15. 		cout << "\t\t|               3. Administrator              |\n";
  16. 		cout << "\t\t|                                             |\n";
  17. 		cout << "\t\t|                                             |\n";
  18. 		cout << "\t\t|                  0. Quit                    |\n";
  19. 		cout << "\t\t|                                             |\n";
  20. 		cout << "\t\t|                                             |\n";
  21. 		cout << "\t\t ----------------------------------------------\n";
  22. 		cout << "Please enter: ";
  23. 		cin >> select; 
  24. 		switch (select) {
  25. 		case 1:
  26. 			LogIn(STUDENT_FILE, 1);
  27. 			break;
  28. 		case 2:
  29. 			LogIn(TEACHER_FILE, 2);
  30. 			break;
  31. 		case 3:
  32. 			LogIn(ADMIN_FILE, 3);
  33. 			break;
  34. 		case 0:
  35. 			cout << "Thanks! Bye" << endl;
  36. 			system("pause");
  37. 			return 0;
  38. 			break;
  39. 		default:
  40. 			cout << "Wrong input! Please re-enter !" << endl; 
  41. 			system("cls");
  42. 			break;
  43. 		}
  44. 		
  45. 	}
  46. 	system("pause");
  47. 	return 0; 
  48. }

 死循环+switch实现界面选择，算是基操了

身份类创建

基类

  1. #pragma once
  2. #include <iostream>
  3.  
  4. // 身份抽象类
  5. class Identity {
  6. public:
  7. 	// 操作菜单  纯虚函数
  8. 	virtual void openMenu() = 0;
  9. 	
  10. 	// 用户名
  11. 	std::string m_name;
  12. 	// 密码
  13. 	std::string m_password;
  14.  
  15. };

 学生类

  1. #pragma once
  2. #include <iostream>
  3. #include "identity.h"
  4.  
  5. class Student : public Identity {
  6. public:
  7. 	int student_id;
  8.  
  9. 	// 默认构造
  10. 	Student();
  11. 	// 有参构造 学号、姓名、密码
  12. 	Student(int student_id, std::string name, std::string pwd);
  13.  
  14. 	// 菜单界面
  15. 	virtual void openMenu();
  16.  
  17. 	// 申请预约
  18. 	void applyOrder();
  19.  
  20. 	// 查看自身预约
  21. 	void showMyOrder();
  22.  
  23. 	// 查看所有预约
  24. 	void showAllOrder();
  25.  
  26. 	// 取消预约
  27. 	void cancelOrder();
  28.  
  29. };

教师类

  1. #pragma once
  2. #include <iostream>
  3. #include "identity.h"
  4.  
  5. class Teacher : public Identity {
  6. public:
  7. 	int teacher_id;
  8.  
  9. 	// 默认构造
  10. 	Teacher();
  11.  
  12. 	// 有参构造 工号、姓名、密码
  13. 	Teacher(int teacher_id, std::string name, std::string pwd);
  14.  
  15. 	// 菜单界面
  16. 	virtual void openMenu();
  17.  
  18. 	// 查看所有预约
  19. 	void showAllOrder();
  20.  
  21. 	// 审核预约
  22. 	void validOrder();
  23.  
  24. };

管理员类

  1. #pragma once
  2. #include <iostream>
  3. #include "identity.h"
  4.  
  5. class Administrator : public Identity {
  6. public:
  7. 	// 默认构造
  8. 	Administrator();
  9.  
  10. 	// 有参构造 账号、密码
  11. 	Administrator(std::string name, std::string pwd);
  12.  
  13. 	// 菜单界面
  14. 	virtual void openMenu();
  15.  
  16. 	// 添加账号
  17. 	void addAccount();
  18.  
  19. 	// 查看账号
  20. 	void showAccount();
  21.  
  22. 	// 查看机房
  23. 	void showRoom();
  24.  
  25. 	// 清空预约
  26. 	void clearOrder();
  27.  
  28. };

登录模块

在头文件中定义所有的使用到的文件名方便不同文件的文件操作

  1. #pragma once
  2.  
  3. // 管理员文件
  4. #define ADMIN_FILE "admin.txt"
  5.  
  6. // 学生文件
  7. #define STUDENT_FILE "student.txt"
  8.  
  9. // 教师文件
  10. #define TEACHER_FILE "teacher.txt"
  11.  
  12. // 机房信息文件
  13. #define COMPUTER_FILE "computerRoom.txt"
  14.  
  15. // 预约文件
  16. #define ORDER_FILE "order.txt"

注：显示中文的话，文件格式采用ansi编码格式保存，utf-8会读出乱码

三种身份的登录及其验证

  1. // 登录功能
  2. void LogIn(string fileName, int type) {
  3.  
  4. 	// 父类指针，用于指向子类对象
  5. 	Identity* person = NULL;
  6. 	ifstream ifs;
  7. 	ifs.open(fileName, ios::in);
  8.  
  9. 	if (!ifs.is_open()) {
  10. 		cout << "No File!" << endl;
  11. 		ifs.close();
  12. 		return; 
  13. 	}
  14.  
  15. 	// 初始化id、名字和密码
  16. 	int id = 0;
  17. 	string name;
  18. 	string pwd;
  19.  
  20. 	// 身份判断
  21. 	if (type == 1) {
  22. 		cout << "Please enter student_ID: " << endl;
  23. 		cin >> id;
  24. 	}
  25. 	else if (type == 2) {
  26. 		cout << "Please enter staff_ID: " << endl;
  27. 		cin >> id;
  28. 	}
  29. 	
  30. 	cout << "Please enter your name: " << endl;
  31. 	cin >> name;
  32.  
  33. 	cout << "Please enter your password: " << endl;
  34. 	cin >> pwd;
  35. 	
  36. 	if (type == 1) {
  37. 		// 学生身份验证
  38. 		int fId;
  39. 		string fName;
  40. 		string fPwd;
  41. 		while (ifs >> fId && ifs >> fName && ifs >> fPwd) {
  42. 		/*	cout << fId << endl; 
  43. 			cout << fName << endl;
  44. 			cout << fPwd << endl; */
  45. 			if (fId == id && fName == name && fPwd == pwd) {
  46. 				cout << "student log in successfully!" << endl;
  47. 				system("pause");
  48. 				system("cls");
  49.                 // 创建学生对象
  50. 				person = new Student(id, name, pwd);
  51. 				studentMenu(person); 
  52. 				return; 
  53. 			}
  54. 		}
  55. 	}
  56.  
  57. 	else if (type == 2) {
  58. 		// 教师身份验证
  59. 		int fId;
  60. 		string fName;
  61. 		string fPwd;
  62. 		while (ifs >> fId && ifs >> fName && ifs >> fPwd) {
  63. 			if (fId == id && fName == name && fPwd == pwd) {
  64. 				cout << "teacher log in successfully!" << endl;
  65. 				system("pause");
  66. 				system("cls");
  67.                 // 创建教师对象
  68. 				person = new Teacher(id, name, pwd);
  69. 				teacherMenu(person);
  70. 				return;
  71. 			}
  72. 		}
  73. 	}
  74. 	else {
  75. 		// 管理员身份验证
  76. 		int fId;
  77. 		string fName;
  78. 		string fPwd;
  79. 		while (ifs >> fName && ifs >> fPwd){
  80. 			if (fName == name && fPwd == pwd) {
  81. 				cout << "admin log in successfully!" << endl;
  82. 				system("pause");
  83. 				system("cls");
  84. 				// 创建管理员对象
  85. 				person = new Administrator(name, pwd);
  86. 				adminMenu(person);
  87. 				return;
  88. 			}
  89. 		}
  90. 	}
  91. 	cout << "Login Fail!" << endl;
  92. 	system("pause");
  93. 	system("cls");
  94. 	ifs.close();
  95. }

管理员身份登录，功能模块：

  1. void adminMenu(Identity*& admin) {
  2. 	while (true) {
  3. 		// 父类指针调用子类共同接口
  4. 		admin->openMenu();
  5. 		// 将父类指针转为子类指针，调用子类其他接口
  6. 		Administrator* ad = (Administrator*)admin; 
  7. 		int select = 0; 
  8. 		cin >> select;
  9. 		// 添加账号
  10. 		if (select == 1)  {
  11. 			cout << " add account " << endl;
  12. 			ad->addAccount();
  13. 		}
  14. 		// 查看账号
  15. 		else if (select == 2) {
  16. 			cout << " show account " << endl;
  17. 			ad->showAccount();
  18. 		}
  19. 		// 查看机房
  20. 		else if (select == 3) {
  21. 			cout << " show room " << endl;
  22. 			ad->showRoom();
  23. 		}
  24. 		// 清空预约
  25. 		else if (select == 4) {
  26. 			cout << " clear order " << endl;
  27. 			ad->clearOrder();
  28. 		}
  29. 		// 注销登录
  30. 		else {
  31. 			cout << "log out" << endl;
  32. 			return;
  33. 			// delete admin;
  34. 		}
  35.  
  36. 	}
  37. }

先写管理员部分，因为学生和老师的账号都由其创建，其职能如下：

头文件定义如下：

  1. #pragma once
  2. #include <iostream>
  3. #include <fstream>
  4. #include "identity.h"
  5. #include "globalFile.h"
  6. #include <vector>
  7. #include "student.h"
  8. #include "teacher.h"
  9. #include "computerRoom.h"
  10. #include <algorithm>
  11.  
  12. void printStudent(Student& s);
  13. void printTeacher(Teacher& t);
  14.  
  15. class Administrator : public Identity {
  16. public:
  17. 	// 默认构造
  18. 	Administrator();
  19.  
  20. 	// 有参构造 账号、密码
  21. 	Administrator(std::string name, std::string pwd);
  22.  
  23. 	// 菜单界面
  24. 	virtual void openMenu();
  25.  
  26. 	// 添加账号
  27. 	void addAccount();
  28.  
  29. 	// 查看账号
  30. 	void showAccount();
  31.  
  32. 	// 查看机房
  33. 	void showRoom();
  34.  
  35. 	// 清空预约
  36. 	void clearOrder();
  37.  
  38. 	// 初始化容器
  39. 	void initVector();
  40.  
  41. 	// 检测重复，参数1是学号/工号，参数2是检测类型
  42. 	bool checkRepeat(int id, int type);
  43.  
  44. 	// 学生容器
  45. 	std::vector<Student> vStu;
  46.  
  47. 	// 老师容器
  48. 	std::vector<Teacher> vTea;
  49.  
  50. 	// 机房容器
  51. 	std::vector<computerRoom> vCom;
  52. };

对于每次添加账号的查重，需要及时保持管理员类中负责学生和老师账号容器的重新初始化，使得重复检测有效。

然后完成学生部分，因为老师是用来审核预约的，因此需要学生主体先创建预约，学生功能如下：

学生登录部分和管理员类似：

  1. // 学生身份登录
  2. void studentMenu(Identity*& student) {
  3. 	while (true) {
  4. 		// 父类指针调用子类共同接口
  5. 		student->openMenu();
  6. 		// 将父类指针转为子类指针，调用子类其他接口
  7. 		Student* stu = (Student*)student;
  8. 		int select = 0;
  9. 		cin >> select;
  10. 		// 申请预约
  11. 		if (select == 1) {
  12. 			cout << "add order " << endl;
  13. 			stu->applyOrder();
  14. 		}
  15. 		// 查看自身预约
  16. 		else if (select == 2) {
  17. 			cout << "show order " << endl;
  18. 			stu->showMyOrder();
  19. 		}
  20. 		// 查看所有预约
  21. 		else if (select == 3) {
  22. 			cout << "show all orders " << endl;
  23. 			stu->showAllOrder();
  24. 		}
  25. 		// 取消预约
  26. 		else if (select == 4) {
  27. 			cout << "clear order " << endl;
  28. 			stu->cancelOrder();
  29. 		}
  30. 		// 注销登录
  31. 		else {
  32. 			cout << "log out" << endl;
  33. 			return;
  34. 			//delete admin;
  35. 		}
  36.  
  37. 	}
  38. }

学生部分的功能涉及到预约的显示操作，因此定义orderFile类用于处理预约记录和更新。

orderFile.h：

  1. #pragma once
  2. #include <iostream>
  3. using namespace std; 
  4. #include "globalFile.h"
  5. #include <fstream>
  6. #include <string>

  14. 	int m_Size;
  15.  
  16. 	// 预约记录，使用嵌套map存储
  17. 	map<int, map<string, string>> m_Data;

  19. 	// 更新预约记录

  21. };

  208. 	int j = 0; 
  209. 	for (int i = 0; i < od.m_Size; i++) {
  210. 		// 先判断自身学号
  211. 		if (this->student_id == stoi(od.m_Data[i]["stuID"])) {

  258. 	std::system("pause");
  259. 	std::system("cls");

最后来编写教师模块，教师身份的职能如下：

教师身份登录：

  1. // 老师身份登录
  2. void teacherMenu(Identity*& teacher) {
  3. 	while (true) {
  4. 		// 父类指针调用子类共同接口
  5. 		teacher->openMenu();
  6. 		// 将父类指针转为子类指针，调用子类其他接口
  7. 		Teacher* tea = (Teacher*)teacher;
  8. 		int select = 0;
  9. 		cin >> select;
  10. 		// 查看所有预约
  11. 		if (select == 1) {
  12. 			cout << "show all orders " << endl;
  13. 			tea->showAllOrder();
  14. 		}
  15. 		// 审核预约
  16. 		else if (select == 2) {
  17. 			cout << "show order " << endl;
  18. 			tea->validOrder();
  19. 		}
  20. 		// 注销登录
  21. 		else {
  22. 			cout << "log out" << endl;
  23. 			return;
  24. 			//delete admin;
  25. 		}
  26.  
  27. 	}
  28. }

老师模块的功能可以大量复用学生部分的代码。

teacher.cpp：

  1. #include "teacher.h"
  2. #include "student.h"
  3. #include "orderFile.h"
  4. #include <vector>
  5. using namespace std; 
  6. // 将数字转换为星期
  7. string daylist[5] = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" };
  8.  
  9. // 默认构造
  10. Teacher::Teacher() {
  11.  
  12. }
  13.  
  14. // 有参构造 学号、姓名、密码
  15. Teacher::Teacher(int id, std::string name, std::string pwd) {
  16. 	this->teacher_id = id;
  17. 	this->m_name = name;
  18. 	this->m_password = pwd; 
  19.  
  20. }
  21.  
  22. // 菜单界面
  23. void Teacher::openMenu() {
  24. 	cout << "\t\t================= Welcome " << this->m_name << "! ==================" << endl;
  25. 	cout << "\t\t ----------------------------------------------\n";
  26. 	cout << "\t\t|              1. Show All Orders             |\n";
  27. 	cout << "\t\t|                                             |\n";
  28. 	cout << "\t\t|               2. Valid Order                |\n";
  29. 	cout << "\t\t|                                             |\n";
  30. 	cout << "\t\t|               Other. Log Out                |\n";
  31. 	cout << "\t\t ----------------------------------------------\n";
  32. 	cout << "Please enter: ";
  33. }
  34.  
  35. // 查看所有预约
  36. void Teacher::showAllOrder() {
  37. 	orderFile od; 
  38. 	if (od.m_Size == 0) {
  39. 		cout << "no order record!" << endl;
  40. 		std::system("pause");
  41. 		std::system("cls");
  42. 		return;

  78. 		return;
  79. 	}
  80. 	
  81. 	cout << "Here are orders to be valided: " << endl;
