This is all of main. TODO #3 is where I am currently struggling. Registered and Guest accounts inherit fields from LoginAccount

string first; string last; string username;

string accountType;

RegisteredAccount gets the field string password and GuestLoginAccount gets the field int expirationInSeconds. Id add the header files but I'm out of space. If this is sufficient information for any help with TODO #3 I'd appreciate it. Thanks.
