Splitting into function files
显示 更早的评论
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);
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
My Professor wants me to split this into multiple function files, I'm not entirely sure how he wants me to accomplish that.

Just call the function's name.
I will give U first sample code :)
Replace code below :
fid = fopen('hangman.txt','r');
if fid < 0, error('Cannot open file'); end
data = textscan(fid,'%s');
data = data{1};
fclose(fid);
with :
filename = 'Hangman.txt';
data = load_data(filename);
Now, create a m-file then type this code :
function data = load_data(filename)
fid = fopen(filename,'r');
if fid < 0,
error('Cannot open file');
end
data = textscan(fid,'%s');
data = data{1};
fclose(fid);
Save the code above with filename : 'load_data.m'.
And try to run your code modified now.

@Chris : Hi,
Would you finish the rest with your own ideas? :)
You said that your professor want to divide it into multiple files.
I have suggested you that your code can be divide into 5 function file as my version.
So, I hope my suggestion would helps you :)

Hello, Chris
Was your professor wants to divide or split this code into multiple function files?
I have tried with my own code,
and I can divide it into 5 function files.
1] load_data.m => function data = load_data(filename)
2] select_word.m => function [word masked] = select_word(data)
3] update.m => function [masked letter_guessed wrong]= update(word, masked, wrong, letter_guessed, letter)
4] check_win => function [complete fail] = check_win(masked, wrong)
5] display_message => function display_message(fail, masked)
And I have main file that named 'main.m'. So, totally I have 6 m-files.

"Open"? Do you mean how to use/call the functions from the main file? Just like you would with any MATLAB function. So it looks like Chandra has moved lines 3 - 7 into the load_data function. This function takes a filename as input and returns data as an output. Hence, in the main code, lines 3 - 7 would be replaced with a single call to load_data:
data = load_data('hangman.txt');

Hello,
After modification, I get my code becomes shorter :
clear, clc;
filename = 'Hangman.txt';
data = load_data(filename);
[word masked] = select_word(data);
complete = 0; wrong = 0;
letter_guessed = '';
while complete == 0
clc; fprintf('%d letters word\n', length(word));
fprintf('Letter guessed : %s\n',letter_guessed);
letter = char(input('Guess a letter : ','s'));
[masked letter_guessed wrong]= update(word, masked, wrong, letter_guessed, letter);
[complete fail] = check_win(masked, wrong);
end
display_message(fail, masked);
But you need to build 5 functions.

I will give you one more.
function [complete fail] = check_win(masked, wrong)
if isempty(findstr(masked,'*'))
complete = 1; fail = 0;
elseif wrong >= 6
complete = 1; fail = 1;
else
complete = 0; fail = 0;
end
Now, you have 3 function files.
See my shorten main file.
So, now you can replace
if isempty(findstr(masked,'*'))
complete = 1;
fail=0;
end
if wrong==6
complete=1;
fail=1;
end
with :
[complete fail] = check_win(masked, wrong);
