Code Explanation
This is a basic example of how you can use functions to create a bank account management system in C++. This example uses a BankAccount struct to store the account information, and three functions: createAccount(), deposit(), and withdraw().
In the main() function, an instance of the BankAccount struct is created with the help of the createAccount() function, account number, account holder name, and initial balance are passed as arguments. The account number, account holder name, and balance are displayed, and the deposit and withdraw functions are tested.
This is a simple program and you can improve it by adding more functionality like account creation, account deletion, passbook printing, statement generation, and many more.
Please note that this is a simple example and is not meant for any real use. It does not include security measures and error checking that would be needed for a real-world application.
