Where to define enums

Question

Say I want to create a card class. and want to have enums for the cards

2,3,4,5,6,7,8,9,J,Q,K,A

Where's the best place to define this, the header file Card.h or Card.cpp?

Answer 1

It's going to be a new type. So I would probably put it on the header file in case I need it in other compilation units.
