Sorry no comments in the code yet. I am stuck. The program runs and does almost everything. The problem I am running into is winAmt returns the wrong number (4 199 040) and newAmt returns the same (4 199 040) in slotMachine function. I thought I understood loops but I get the feeling I am not declaring something properly and I am losing betAmt and/or startAmt.

Thank you in advance.

You're never assigning new values (or any values in fact; they're not initialised) to winAmt or newAmt

Why are you wearing that ridiculous respirator, Salem?
