Two bank account: current and saving. User has to be asked to choose one, then withdraw money. How can I do a decrement of the balance each time I loop in this function?? if balance = 10 euro , withdraw 5 so remaining is 5. User is asked to quit or continue , if continues the new withdrawal will be deducted from the new balance 5 euro not from 10 Euro.??? Could do all code but no idea how to let the decrement from new balance?????
