Task 5 You are working at a bank, and you are responsible for setting up the ATM machines programming. These are the function and related guidelines: Once the customer inserts the card (program starts) > The ATM displays a request to the customer to enter the password. > If the entered password is incorrect, the ATM will ask the customer to re-enter the password. > If the second try is also unsuccessful, then the ATM will ask the customer to re-enter the password for the third, and last, trial. > If all three trials failed, the ATM machine will capture the card and display a message to the customer about the situation > If any of the three trials was successful, the ATM screen will display three options Option 1: current balance. > If chosen by customer, the ATM would display the current balance (amount of money) in the customer's account. > The ATM also displays a question if the customer wants to go back to the 'Options' display, with a Y/N acceptable inputs by customer. Option 2: cash withdrawal. > If chosen by customer, the ATM asks to enter the amount to be withdrawn. > The ATM will compare against the available account balance. If all good, withdrawal will be successful, and the account balance will be updated (inside the ATM memory). If not, a message will be displayed that the balance is less that the requested withdrawal amount. The ATM also displays a question if the customer wants to go back to the 'Options' display, with a Y/N acceptable inputs by customer. Option 3: end transaction. > If chosen by customer, the ATM displays a thank you note with a message that the transaction is completed and another message that the customer should pick up the card. 5-A) Draw a flowchart that illustrates how ATM works. 5-B) Write a MATLAB code that resembles a fully functioning ATM. Assume that the current password of a specific card is 1234, and that the current balance is 10,000 JD. (Hint: your program should have these info as a pre-set data)
