paralax rfid code help

i am trying to read an rfid card and if it equal to a defined user allow them access to something.
i have read the codes in fine however im not sure if im defining the user correctly. this is how im defining the user
const char Stephen[11] = “8400338A85”;
is this the correct way of doing this? i previously had them declared by just
char Stephen[11] = “8400338A85”;

So far so good. Const or not won't make a huge amount of difference.

This may give you some inspiration:
