      masked(stat) = letter;

  end    
end
if fail==0
  clc; fprintf('You win, the word is : %s\n',masked);
elseif fail==1
  disp('You lose')
end

How would I display all the letters the to the user, so they can see what letters they already guessed? Like if I guess an E, and there is no E, I want the program to show that I guessed E. And continue to do that for every guess, and list all the letters I've guessed.

And how do I get my words to be not be case sensitive? :[

Hello,

I modify my 'hangman.txt' at first line :

Signature
chair
calculator
window
picture
browser
phone
book
table
glass

Note that 'signature' becomes 'Signature'

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 = lower(data{index});
masked = word; 
masked(~isspace(masked)) = '*';
complete = 0;
wrong=0;
letter_guessed = '';
while complete == 0
  clc;
  %fprintf('Word : %s\n',masked);
  fprintf('Letter guessed : %s\n',letter_guessed);
  letter = char(input('Guess a letter : ','s'));
  stat = findstr(word,letter);
  fprintf('letters used so far\n',letter);
  if ~isempty(stat)
      masked(stat) = letter; 
      letter_guessed = strcat(letter_guessed,letter);
  elseif ~isequal(word,letter)
      wrong=wrong+1; 
  end
  if isempty(findstr(masked,'*'))
      complete = 1;
      fail=0;
  end
  if wrong==6
      complete=1;
      fail=1;
  end    
end
if fail==0
  clc; fprintf('You win, the word is : %s\n',masked);
elseif fail==1
  disp('You lose')
end

Thank you! Would you have any idea how to solve my first question?

[Chandra Kurniawan]

Do you mean 'list all the letters I've guessed'??

[Walter Roberson]

Chandra, Chris is doing a school assignment, and you are giving him complete answers for that assignment :(

[Chris]

I've put some things together, but Chandra has helped me tremendously. And yes I mean that.

[Chandra Kurniawan]

Oh sorry before.

It's will be better if I give you hint step-by-step :)

So, dont you see line : letter_guessed = '';

I store every words that has been guessed to variable 'letter_guessed' at line :

letter_guessed = strcat(letter_guessed,letter);

Then I decide not to display the masked word at line :

%fprintf('Word : %s\n',masked);

Have you run my code?

[Chris]

Yes, I've used your code ;].

%Clears all data from previous program

clear

clc

%Opens text file with words

fid = fopen('hangman.txt','r');

%If file name isn't correctly spelt, file fails to open

if fid < 0, error('Cannot open file'); end

data = textscan(fid,'%s');

%Initialize

data = data{1};

%Closes text file

fclose(fid);

%Chooses a random word from text file

index = ceil(rand * numel(data));

%Makes word not case sensitive

word = lower(data{index});

masked = word;

%Replaces characters with astferisks

masked(~isspace(masked)) = '*';

complete = 0;

wrong=0;

letter_guessed = '';

while complete == 0

clc;

fprintf('Word : %s\n',masked);

letter = char(input('Guess a letter : ','s'));

stat = findstr(word,letter)

fprintf('Word : %s\n',masked);

if ~isempty(stat)

masked(stat) = letter;

letter_guessed = strcat(letter_guessed,letter);

elseif ~isequal(word,letter)

wrong=wrong+1;

end

if isempty(findstr(masked,'*'))

complete = 1;

fail=0;

end

if wrong==6

complete=1;

fail=1;

end

end

if fail==0

clc; fprintf('You win, the word is : %s\n',masked);

elseif fail==1

disp('You lose')

end

Try running that, yours left the asterisks out. The letters that were guessed do not appear still.

Good job!
