If a withdrawal is requested, prompt the user to enter the amount of the withdrawal (use a double for this). if the proposed withdrawal amount is less than or equal to the initial balance, print "your current balance is $x. xx" where x. xx is the new balance after the withdrawal, and then re-display the prompt and await the next transaction type. if the proposed withdrawal amount exceeds the initial balance, print "insufficient funds. your current balance is $x. xx" where x. xx is the initial balance, and then re-display the prompt and await the next transaction type.
