The document contains code for an automated teller machine (ATM) program. The program prompts the user to enter a password, and if correct, displays a menu to make transactions including: checking balance, withdrawing money, depositing money, and exiting. Based on the user's selection, it performs the appropriate transaction by updating the balance variable and displaying the current balance. This repeats until the user chooses to exit the program.
