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.
I need help with pointers and how to take the user input of id,lab,and station to update the output screen.
