You run four computer labs. Each lab contains computer stations that are numbered as shown in the table below:-

Lab Number	Computer Station Numbers
1	1-5
2	1-6
3	1-4
4	1-3

Each user has a unique five-digit ID Number. Whenever a user logs on, the user's ID, Lab Number, and the computer station are transmitted to your station. For example, if user 49193 logs onto station 2 in Lab 3, your system receives (49193, 2, 3) as input data. Similarly, when a user logs off a station, your system receives the Lab Number and computer station number.

Write a computer program that could be used to track, by lab, which user is logged onto which computer. For example, if user 49193 is logged into station 2 in lab 3 and user 99577 is logged into station 1 of lab 4, then your system might display the following:-

Lab Number Computer Stations

1 1: empty 2: empty 3: empty 4: empty 5: empty

2 1: empty 2: empty 3: empty 4: empty 5: empty 6: empty

3 1: empty 2: 49193 3: empty 4: empty

4 1: 99577 2: empty 3: empty

Task:-

1. Create a menu that allows the administrator to simulate the transmission of information by manually typing in the login or logoff data. Whenever someone logs in or out, the display table should be updated.

2. Write a search option so the administrator can type in a user Id and the system will output what Lab Number and station number the user is logged into, or "None" if the user Id is not logged into any computer station.

You should use a fixed array of length 4 for the labs. Each array entry points to a dynamic array that stores the user login information for each respective computer station.

// Sample Function prototypes void createArrays(IntPtr labs[], int labsizes[]);

// This function should create the dynamic arrays for the labs. The first array is the array of labs, the second array contains the size (or number of computers) we will put in each //lab. This dictates the size of the dynamic array. void freeArrays(IntPtr labs[]); // Releases memory we allocated with "new".

void showLabs(IntPtr labs[], int labsizes[]); //Displays the status of all labs (who is logged into which computer). void login(IntPtr labs[], int labsizes[]); //Simulates a user login by asking for the login info from the console.

void logoff(IntPtr labs[], int labsizes[]); //Searches through the arrays for the input user ID and if found logs that user out. void search(IntPtr labs[], int labsizes[]); //Searches through the arrays for the input user ID and if found outputs the station number.

Write this in C++

++++

Instead of a dynamic array to store the list of user ID's for each computer station, use a linked list. The node for the lists should contain the station number and user ID of the person logged in on that station. If nobody is logged on to a computer station, then no entry should exist in the linked list for that computer station.

Adding to it! Please Write it in C++ with comment to explain and understand how you did it. Thank you and Have a Nice DAy!
