HELP!! Any assistance would be awesome, including any .h files and comments please!!

Programming Assignment 3

Using the same employee class developed in the Week 2 programming assignment, develop a new program that simulates the hiring and processing of new employees for your company. The queue should be a First In First Out (FIFO) based queue.

Input Data about current employees should be on the file "Employee.txt". You will need to create your own employee file and submit it with the final project.

Each employee should have the following attributes:

Employee_Number Integer

Employee_Last_Name String

Employee_First_Name String

Employee_Years_of_Service Integer 3 employees must be loaded from the Employee.txt file on program start up.

Functionality

Command	Processing
ADD NEW EMPLOYEE	Allows the user to Add add a new employee to the queue
REMOVE EMPLOYEE	Allows the user to Remove an employee from the queue
SIZE	Returns the number of Employees in the queue
QUIT	Stops processing

Output

All output should be on the console.

Data Structures

This program should implement a queue as a linked structure (5.4).

Below is what I have for the previous week.
