![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withdrawn.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)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd8d30b82-61bb-4fd4-8ecf-0a317b430176%2F6c07c3ce-40c9-49ae-9966-f53949a6d07a%2Ft0rm4j_processed.png&w=3840&q=75)
