programming C++ for potentiometer

could someone post a sample code for reading the output of a potentiometer? We’ve got ours hooked up to AnalogChannel(1), and upon pressing a certain button on the gamepad, want to run a motor until the potentiometer reaches a certain value.
i have searched all over for sample code here, but have found what’s there to be of limited use to us, being the novices with this as we are.
Thanks so much!

this always happens to me - I can spend an hour searching for a thread, then as soon as I post my question, I finally find the thread. for anyone looking for the same topic, check out
