C++ pass enum as parameter

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?

Solution 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.

Solution 2

Suit is part of the class Card's namespace, so try:

Card::Suit suit = Card::CLUBS;

WTF, Card.CLUBS doesn't give you an error??? I'd think it needs to be Card::CLUBS... x_x

use Card.CLUBS as it will match with question.
