Scoped enum as input to function

[kyrresc]

This should be easy but.. I have the following scoped enum defined

enum class Suit{clubs,diamonds,hearts,spades};

how do I pass it to a function and do a switch case on it? I'm getting all kind of errors. I've gotten this far:

string suitToString(Suit suit) {

//switch (suit) {

//case 

[JLBorges]

std::string to_string( Suit s ) {

    switch(s) {

        case Suit::clubs : return "clubs" ;
        case Suit::diamonds : return "diamonds" ;
        case Suit::hearts : return "hearts" ;
        case Suit::spades : return "spades" ;
    }
}

Or

std::string to_string( Suit s ) {

    static const std::string text[] { "clubs", "diamonds", "hearts", "spades" };

    return text[ int(s) ] ;
}
