ATMcontroller

ATM Controller that allows you to see your bank balance according to the flowchart above.

Description

ATM Controller works as follows:

1. User inserts a card.
2. If valid, user is prompted to enter the PIN number.
3. If PIN valid, the user is prompted to select between savings or checking account.
4. Once account type is selected, user can choose among three options: see balance, make deposits or withdraw cash.
5. If invalid PIN is entered three times, account will be locked and will only be able to be unlocked by calling the bank.
6. If not enough bank account balance, the user will not be able to withdraw cash.
7. If not enough cash in the ATM, the user will not be able to withdraw cash.
