Computer sign-in/sign-out

Deadweight77 (98)
So I've been trying to code a simulation in which you can sign into a computer in a computer lab. First you must enter in the lab you wish (1-4) and a seat. Each lab has their own specified seats available such as lab 1 has 5 seats while lab 2 has 6. I only have the login function for now because when I call upon the status function, which is supposed to display all seats that are taken and not taken, it doesn't work.

I don't know if you're required to have your functions the way they are, but generate should be a constructor. Why? Because that way, it's harder to forget to call it before you call status, as you do in your program.

Are you allowed to use std::vector? I think it would help you here.

Yea I could use vectors,but I'm not sure how I should incorporate it.
