这是C++总结性练习,主要以一个综合案例对以前学过的知识进行复习巩固,为以后编程打下基础。
学校有几个规格不同的机房, 由于使用时经常出现“撞车”现象,现开发一套机房预约系统,解决这一问题
分别有三种身份使用该程序
机房总共有三件
首先进入登录界面,可选登录身份有:
每个身份都需要进行验证后,进入子菜单
学生具体功能
教师具体功能
管理员具体功能
功能描述:
设计主要菜单,与用户进行交互
在主函数中添加菜单提示
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
break;
case 2://老师身份
break;
case 3://管理员身份
break;
case 0://退出系统
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;

#pragma once
#include
#include
using namespace std;
//身份抽象类
class Identity {

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:
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) {

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) {

//进入管理员身份的子菜单
return;
}
}
}

Manager::Manager(string name, string pwd)
{
this->m_Name = name;
this->m_Pwd = pwd;
}
在机房预约系统.cpp中,当用户登录的是管理员,添加管理员菜单接口
将不同的分支提供出来
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

功能要求:



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;
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:
解决方案:
//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");
}

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
using namespace std;
#include
#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:
OrderFile::OrderFile()
{
ifstream ifs;
ifs.open(ORDER_FILE, ios::in);
string date;//日期
string interval;//时间段
string stuId;//学生编号
string stuName;//学生姓名
string roomId;//机房编号
string status;//预约状态
this->m_Size = 0;//记录条数
while (ifs >> date && ifs >> interval && ifs >> stuId
&& ifs >> stuName && ifs >> roomId && ifs >> status) {
//测试
//cout << date << endl;
//cout << interval << endl;
//cout << stuId << endl;
//cout << stuName << endl;
//cout << roomId << endl;
//cout << status << endl;
//cout << endl;
string key;
string value;
map<string, string> m;
//截取时间段
int pos = date.find(":"); // 4
if (pos != -1) {
key = date.substr(0, pos);
value = date.substr(pos + 1, date.size() - pos - 1);
m.insert(make_pair(key, value));
}
//截取间隔
pos = interval.find(":");
if (pos != -1) {
key = interval.substr(0, pos);
value = interval.substr(pos + 1, interval.size() - pos - 1);
m.insert(make_pair(key, value));
}
//截取学号
pos = stuId.find(":");
if (pos != -1) {
key = stuId.substr(0, pos);
value = stuId.substr(pos + 1, stuId.size() - pos - 1);
m.insert(make_pair(key, value));
}
//截取姓名
pos = stuName.find(":");
if (pos != -1) {
key = stuName.substr(0, pos);
value = stuName.substr(pos + 1, stuName.size() - pos - 1);
m.insert(make_pair(key, value));
}
//截取机房号
pos = roomId.find(":");
if (pos != -1) {
key = roomId.substr(0, pos);
value = roomId.substr(pos + 1, roomId.size() - pos - 1);
m.insert(make_pair(key, value));
}
//截取状态
pos = status.find(":");
if (pos != -1) {
key = status.substr(0, pos);
value = status.substr(pos + 1, status.size() - pos - 1);
m.insert(make_pair(key, value));
}
//将小map容器放入到大的map容器中
this->m_orderData.insert(make_pair(this->m_Size, m));
}
ifs.close();
//测试最大map容器
//for (map>::iterator it = m_orderData.begin();
// it != m_orderData.end(); it++) {
// cout << "条数为:" << it->first << " value = " << endl;
// for (map::iterator mit = (*it).second.begin();
// mit != (*it).second.end(); mit++) {
// cout << " key = " << mit->first << " value = " << mit->second << " ";
// }
// cout << endl;
//}
}
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();
}
在Student类的 void Student::showMyOrder() 成员函数中,添加如下代码:
//查看自身预约
//查看自身预约
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++) {
//string 转 int
//string 利用 .c_str() 转 const char*
//利用 atoi(const char*) 转 int
if (atoi(of.m_orderData[i]["stuId"].c_str()) == this->m_Id) {
cout << "预约日期: 周" << of.m_orderData[i]["date"];
cout << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午": "下午");
cout << " 机房号:" << of.m_orderData[i]["roomId"];

在Student类的 void Student::showAllOrder() 成员函数中,添加如下代码:
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"];

status += "预约已取消";
}
cout << " " << status;
cout << endl;
}
system("pause");
system("cls");
}

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()

v.push_back(i);
cout << index++ << "、 ";

}

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;
}
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
添加全局函数 void TeachrMenu(Identity*& teacher)
//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()
{
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:";
}
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
TeacherMenu(person);
return;
}
}
}

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 << " 时间段:" << (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:";
//1 审核中 2 已预约 -1 预约失败 0 取消预约
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 += "预约失败,审核未通过";
}
else {
status += "预约已取消";
}
cout << " " << status;
cout << endl;
}
system("pause");
system("cls");
}

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()
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 << " 时间段:" << (of.m_orderData[i]["interval"] == "1" ? "上午" : "下午");
cout << " 学生编号:" << of.m_orderData[i]["stuId"];
cout << " 学生姓名:" << of.m_orderData[i]["stuName"];
cout << " 机房编号:" << of.m_orderData[i]["roomId"];
string status = "状态: 审核中";
cout << status << endl;
}
}
cout << "请输入审核的预约记录, 0代表返" << endl;
int select = 0;//接收用户选择的预约记录
int ret = 0;//接收预约结果记录
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) {
//通过
of.m_orderData[v[select - 1]]["status"] = "2";
}
else {
//不通过
of.m_orderData[v[select - 1]]["status"] = "-1";
}
of.updateOrder();//更新记录
cout << "审核完毕" << endl;
break;
}
}
cout << "输入有误,请重新输入!" << endl;
}
system("pause");
system("cls");
}
