you will design and implement a script that operates an ATM machine. Your script should be able to let users withdrawn money from their checkings or savings account, transfer money between accounts, and check the accounts' balances. Your sscript should also identify the user by its username and check the user's password before completing any operation.
you must have some ideas. Is this a bash script?
I assume you know how to do SQL queries.
its just a bash script. we do have txt file with it which contains 3 usernames, passwords and their balances...the file is not suppose to get updated with balance...no SQL queries etc..Im new to this field so need some help with it. Thanks
To design and implement a script that operates an ATM machine, you can follow these steps:
1. Create a database or data structure to store user information, including their username, password, checking account balance, and savings account balance. You can use a dictionary or a database management system like SQLite or MySQL.
2. Set up a user interface for the ATM machine. This can be a command-line interface or a graphical user interface, depending on your preference.
3. Prompt the user to enter their username and password to log in. Ensure that the username and password match what is stored in the user database.
4. Once the user logs in successfully, present them with a menu of options, such as withdrawing money, transferring funds, or checking balances.
5. If the user selects the option to withdraw money, prompt them to choose which account (checking or savings) they want to withdraw from. Then, ask for the withdrawal amount. Subtract the withdrawal amount from the selected account's balance and update the database accordingly.
6. If the user chooses to transfer funds between accounts, ask them to specify the source account (checking or savings) and the destination account. Then, prompt them for the transfer amount. Subtract the transfer amount from the source account's balance and add it to the destination account's balance, updating the database accordingly.
7. If the user selects the option to check balances, display the current balance of both the checking and savings accounts.
8. After completing any operation, give the user the option to perform another transaction or to exit the program.
Remember to handle error cases, such as incorrect login credentials, insufficient funds, or invalid input.
This is just an outline to get you started. You can expand and customize the script as per your requirements.
