clear all clc

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};

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
