String help!?

fid = fopen('hangman.txt', 'r'); if fid < 0, error('Cannot open file.'); end CC = textscan(fid, '%s'); C = CC{1}; fclose(fid); index = ceil(rand * numel(C)); word = C{index};

stars = word; stars(~isspace(stars)) = '*';

first_guess=char(input('Enter letter \n'));

result1 = ~isempty(findstr(word,first_guess));

first_guess = 'l'; stars(original == first_guess) = first_guess;

When I try entering a letter to see if it matches one in the word, it returns an error. Enter letter l ??? Error using ==> input Undefined function or variable 'l'.

first_guess=char(input('Enter letter \n','s'));

use letter=input('Enter One letter: \n','s') to get the letter directly.
