The document contains code for an automated teller machine (ATM) program. It prompts the user to enter a password, and if correct, displays a menu to make transactions. The menu includes options to check the balance, withdraw or deposit money, and exit. Based on the selection, it performs the transaction and displays the new balance. It loops to re-enter the password if an incorrect one is provided.
