The objectives of this project:
- Connect to the database (the database name is passed as an argument).
- Create table "card" if it doesn't exist.
- Generate a bank card number using the Luhn algorithm (the bank card number must start with 4000 00).
- Generate a random pin.
- Create a menu for the user, where you can:
- Check balance;
- Add amount;
- Do transfer;
- Close your account.
- When doing transfer, process errors if you enter:
- Your bank card number;
- Bank card number that does not correspond to the Luhn algorithm;
- A bank card number that does not exist;
- The transfer amount is greater than the user's current balance.
