Using Protected Instead of Private

A base class BankAccount has been provided with a protected int accountNumber and a constructor that initializes it.

A derived class CheckingAccount publicly inherits from BankAccount. The displayAccount() function has been declared.

Your task is to implement displayAccount() so that it prints:
Account: [accountNumber]

Because accountNumber is protected (not private), it can be accessed directly in the derived class.

Do NOT include a main function. Your code will be tested automatically.

Expected Output:

Account: 12345↵

= newline. The output ends with a newline — print one after the last line.
