clear all clc

original='Hello World'; Word = word; Word(~isspace(Word)) = '*'
first_guess=char(input('Guess a letter \n','s'));
result1 = ~isempty(findstr(word,first_guess));
selected = first_guess; stars(original == first_guess) = first_guess
OUTPUT Word =
*******
Guess a letter i
stars =
Empty string: 1-by-0
The word is signature, but I don't unerstand how it outputs an empty string. Also, how would I get the letter to replace the asterisk after each guess? Would I end up using a while loop to keep the user guessing until the word is uncovered? This is a lot harder than I thought it would be.

Hangman text is just a document filled with different words.My program is supposed to be a hangman game.It chooses a random word from that document.The asterisks are there to shield the user from the answer. Although, I did figure some of the problem out, I still do not know how to get the asterisks show up with the letters if the user guesses correctly.
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};
Word = word;
Word(~isspace(Word)) = '*'
first_guess=char(input('Guess a letter \n','s'));
result1 = ~isempty(findstr(word,first_guess));
selected = first_guess;
Progress(word == first_guess) = first_guess
OUTPUT
Word =
*********
Guess a letter
e
Progress =
e

Hello,
So long time you have waiting. Here I give you my code.
I have 'Hangman.txt'
signature
chair
calculator
window
picture
browser
phone
book
table
glass
And this is my code :
clear; clc;
fid = fopen('Hangman.txt','r');
if fid < 0, error('Cannot open file'); end
data = textscan(fid,'%s');
data = data{1};
fclose(fid);
index = ceil(rand * numel(data));
word = data{index};
masked = word;
masked(~isspace(masked)) = '#';
complete = 0;
while complete == 0
clc;
fprintf('Word : %s\n',masked);
letter = char(input('Guess a letter : ','s'));
stat = findstr(word,letter);
if ~isempty(stat)
masked(stat) = letter;
end
if isempty(findstr(masked,'#'))
complete = 1;
end
end
clc; fprintf('Word : %s\n',masked);
Just try to run it.

Wow, thank you! I do have a couple more questions. How would I add a break to that after the user guesses 6 times.

You do not need a CHAR in "char(input('Guess a letter : ','s'))".

Use ismember to determine if the letter 'is a member' of the word.
%Sample word, disguised word and letter guess
word = 'signature';
word_disguised = repmat('*',size(word));
letter = 'q'; %try various letters
%Engine
idx = ismember(word,letter); %index of members
if ~any(idx)
disp('Fail Lose an arm!');
else
word_disguised(idx) = letter;
end
