In the below code Add a main menu to manage the employees data, which will include a choice of: 1) Access employee record based on employee ID only (can be the index of the array, you may not to perform a search, this is called Hashing 2) Add an employee to the database 3) Delete an employee (delete the index), if an ID is available use it for the new employee

#include #include using namespace std;

class Employee { private: string name; // Employee's name int idNumber; // ID number string department; // Department name string position; // Employee's position

void setPosition(string p) { position = p; }

// Accessors string getName() { return name; }
