You are writing a program that will act like an atm machine by the end of this course. in order to access the atm, the customer must enter their user name and their passcode. after 3 incorrect attempts at entering the user name and password, the program will end. the list of legitimate users along with their user id, passcode and account balance will be provided to you.

there are only 5 functions that can be carried out by the atm:

1 – deposit (adding money to the account)

2 – withdrawal (removing money from the account)

3 – balance inquiry (check current balance)

4 – transfer balance (transfer balance from one account to another)

5 - log out (exits/ends the program)

allow the user to make up to a maximum of 3 transactions at a time. after 3 transactions, the program will terminate. after a transaction is completed, the program will update the running balance and give the customer a detailed description of the transaction. a customer cannot overdraft on their account; if they try to withdraw more money than there is, a warning will be given to the customer. also note that the atm doesn’t distribute or collect coins – all monetary values are in whole dollars (e. g. an integer is an acceptable variable type). any incorrect transaction types will display an appropriate message and count as a transaction.
