大二上的时候跟着书做的一个员工管理系统（c++实现，适合拿来混过c++的课程设计）

/*==========================*/
//Database.cpp对员工信息的各种操作

//实现Database类
#include <iostream>
#include <string>

#include "Database.h"

using namespace std;


  Database::Database()
  {
    mNextSlot = 0;
    mNextEmployeeNumber = kFirstEmployeeNumber;
  }

  {
  }
//建立一个新的员工信息
  Employee& Database::addEmployee(string inName)
  {
    if (mNextSlot >= kMaxEmployees) {
      cout << "There is no more room to add the new employee!" << endl;
    }

    Employee& theEmployee = mEmployees[mNextSlot++];
    theEmployee.setName(inName);
    theEmployee.setEmployeeNumber(mNextEmployeeNumber++);
    theEmployee.hire();

    return theEmployee;
  }
//查询某个员工信息by number
  Employee& Database::getEmployee(int inEmployeeNumber)
  {
    for (int i = 0; i < mNextSlot; i++) {
      if (mEmployees[i].getEmployeeNumber() == inEmployeeNumber) {
    return mEmployees[i];
      }
    }

    cout<< "No employee with employee number " << inEmployeeNumber << endl;
  }
//查询某个员工信息by name
  Employee& Database::getEmployee(string inName)
  {
    for (int i = 0; i < mNextSlot; i++) {
      if (mEmployees[i].getName() == inName) {
    return mEmployees[i];
      }
    }

    cout << "No match with name " << inName << endl;

  }
//输出所有员工信息
  void Database::displayAll()
  {
    for (int i = 0; i < mNextSlot; i++) {
      mEmployees[i].display();
    }
  }
//输出所有雇用员工信息getIsHired()返回为ture
  void Database::displayCurrent()
  {
    for (int i = 0; i < mNextSlot; i++) {
      if (mEmployees[i].getIsHired()) {
    mEmployees[i].display();
