b. Using a Sequence Diagram model the following scenario: withdrawing money from an ATM (10 points). i. There are two objects (cardholder, and ATM system). ii. The cardholder is attempting to withdraw money therefore: iii. We must have an insert card function. iv. You must have a validation function (insert PIN with a loop for incorrect inputs) v. You must have an insert amount to withdraw function. vi. You must have a balance check function when a withdrawal of amount xyz is requested, if the amount requested is less than the amount available then you can dispense the cash, and if the amount requested is more than the amount that is available then you must send an error. vii. Typical completion of an ATM transaction such as returning the card and printing a receipt (or not hint: another conditional statement). viii. Now that you have all this information you are ready to construct the Sequence Diagram for this system.
