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;
wrong=0;
while complete == 0
clc;
fprintf('Word : %s\n',masked);
letter = char(input('Guess a letter : ','s'));
stat = findstr(word,letter);
fprintf('letters used so far',letter);
if ~isempty(stat)
masked(stat) = 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
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?

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

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

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

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
Chris 2011-12-6
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.
