Hello,
I am working on a project for a class I have making a Hangman game. I am trying to input guessed letters into a blank array, but when they are inputted, they show up as the number associated with each letter.
Here is the code I am using:
letters = ismember(word,guess); %letters is a logical array with 1s where the guess, a single letter, is in the word
word_display(letters == 1 ) = guess; %where letters==1, guess is inputted into word display, a zeros array with length of the word.
How do I make it where the word_display displays the letters and not their number that is given them by MATLAB
Thanks!

Start with
word_display = blanks(length(word));
then at each iteration
[letters, idx] = ismember(word,guess);
word_display(letters) = guess;

If I use this method, then I loose my placeholders in my display array. Are there any other methods I am unaware of?

Start with
word_display = repmat('_', 1, length(word));
