it keeps showing unreferenced local variable for 'pick'and 'userticket'... I'm so confused with using references and pointers!!!!

This is only a warning and isn't a problem.

You have a problem with ans. Since you declared it as int you cannot enter a non numeric value. If you do you have an infinite loop (cin doesn't stop for input anymore). Change the type of ans to char.
