Question

Would someone be able to compose the following program to be written in C++, along with a constructed text file to run with it. If you could most importantly comment your code, that would be helpful to a beginner. Just need something neat, and efficient. Showing sample output to confirm it will compile is important. Please see code snippet below:

Your assignment is to implement a singly linked pointer based list using an employee class. The employee class should contain the empl oy ee information listed in the "input" section below. The program should contain all functions listed in the functionality section below. 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: Integer String String Integer .Employee_Number Employee Last_Name . Employee_First Name Employee_Years_of Service 3 employees must be loaded from the Employee.txt file on program start up. Functionality Command ADD REMOVE COUNT PRINT QUIT Processing Select table columnle user to "Add" an employee to the list ows the user to "Remove" an emplovee from the list Returns the number of emplovees in the list Prints the emplovee information in the list to the console Stops processin Output All output should be on the console. Data Structures This program should utilize a singly linked pointer based list.
