Black jack function for hiding dealers card

I have the game pretty much completed. its a text based version of blackjack just focusing on random integers since suits dont really matter.

I need a function to store the hole card, display an empty string (ex: __ / 9 / 2) and then display the value once the player "stays".

Thank you!

I'll assume the dealer's cards are stored as an array with the hole card being first. Then here's a function that takes two input arguments: (1) dealer's card array, (2) a logical indicating whether to hide the hole card, and returns a character array representing the cards:

function str = get_str(d,do_hide)
    d = num2cell(d);
    str = sprintf('%2d / ',d{:});
    str(end-2:end) = [];
    if do_hide
        str([1 2]) = '_';
    end
end

Wouldn't that be sprintf() or fprintf()?

No so in the beginning it deals, and then it needs to store the card but not show the value of the card until the end. Does that make sense?

Nope.
