Trying to get the program to display if the letter is in the word.

And word = any word

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};

first_guess=input('Enter letter'); result1=findstr(word,'first_guess')

在 MATLAB Online 中打开

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

I am taking you at your word here that you just want to display if the letter is in the word -- as opposed to displaying the positions that it occurs in the word.

Note: findstr() has been recommended against for a number of years now -- since before I started using MATLAB. strfind() is recommended in its place.
