IDENTIFY THESE BODY PARTS OF THE FROG? Put structure under its images

Identify all you can recognize. I know that some are hard to see.

COMPUTER LABS PROJECT

You run four computer labs.Each lab contains computer stations that are numbered as 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
users's ID,lab number,and the computer station number are transmitted
to your system.For example,if the user 49193 logs onto station 2 in lab 3,
then your sytem recieves(49193,2,3) as input data.Similarly,when a user
logs off a station,then your system recieves 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 users 49193 is logged into staion 2 in lab 3 and
user 99577 is logged into station 1 of ab 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

Create a menu that allows the administrator to simulate the transmssions of information by
manually typing in the login or logoff data. whenever someone logs in or out the display
should be updated. also write a search option so that the administrator can type in a user
ID and the system will output what lab and station number that 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.

I would like to use these functions below this as far i got.

Create Arrays(Int Ptr labs [],int lab sizes)Creates dymanic arrays for users

Free Arrays(Int Ptr,Labs[])//Releases memory allocated with "new"

Show Labs(Int Ptr,Labs[],int lab sizes[])//Displays the status of all labs who are logged into which computer.

Login(Int Ptr Labs[],int lab sizes[])//Simulates a user logging in searches through arrays for I.P user Id

Logoff(Int Ptr Labs[],int lab sizes[])//Searches through arrays for I.P user Id if found logs that user out.

Search(Int Ptr labs[],Int lab sizes[])//Searches through the arrays for the I.P user Id if found outputs the station number.
