Question

If I have a simple class like this one for a card:

class Card {
        public:
            enum Suit { CLUBS, DIAMONDS, HEARTS, SPADES };
            Card(Suit suit);
    };

and I then want to create an instance of a card in another file how do I pass the enum?

#include "Card.h"
using namespace std;
int main () {
    Suit suit = Card.CLUBS;
    Card card(suit);
    return 0;
}

error: ‘Suit’ was not declared in this scope

I know this works:

#include "Card.h"
using namespace std;
int main () {
    Card card(Card.CLUBS);
    return 0;
}

but how do I create a variable of type Suit in another file?

Answer 1

Use Card::Suit to reference the type when not inside of Card’s scope. …actually, you should be referencing the suits like that too; I’m a bit surprised that Card.CLUBS compiles and I always thought you had to do Card::CLUBS.
