The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.
Ran `make www timestamp` to perform the above.

|
||
<h2 id="judges-remarks">Judges’ remarks;</h2>
|
||
<p>Everyone talks about how data hiding can produce clearer code; I am
|
||
pleased to offer this charming refutation.</p>
|
||
<p>The program is a simple game. A bit of observation reveals that the
|
||
game has some data - but where? It’s unclear which of the contents of
|
||
the program are used.</p>
|
||
<p>Curiously, the program only works if its source is in the directory
|
||
it’s run in. More curiously, the program would fail if the program’s
|
||
name’s second letter wasn’t <code>r</code> (the source has been changed for your
|
||
convenience and this restriction no longer exist).</p>
|
||
<p>Modern design has come a long way since the unreadable, tightly-coupled
|
||
systems we used to have.</p>
|
||
<p>Extra credit questions:</p>
|
||
<ul>
|
||
<li>Where are the words stored?</li>
|
||
<li>How many words does this entry use?</li>
|
||
<li>Can you add more words to the program and still make it work?</li>
|
||
<li>Are there any misspelt words? If yes what are they?</li>
|
||
</ul>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This program lets you guess English words. It displays an underscore
|
||
for each letter in the word; guessing a letter that actually is in
|
||
the word replaces the corresponding underscores with the letter
|
||
itself. You can guess a letter simply by typing it in. If your C
|
||
implementation requires it, you may have to hit Return before it
|
||
is recognized. In this case, you can also type multiple guesses
|
||
on the same line (completely solve it by entering
|
||
<code>abcdefghijklmnopqrstuvwxyz</code>). Execution stops when all underscores
|
||
have been replaced.</p>
|
||
<p>The program offers a number of different words to guess, <code>time()</code> is
|
||
used to pick one at random. All words are eight characters long.</p>
|
||
<p>The source should compile with any ANSI C compiler (I used CodeWarrior
|
||
w/ ANSI strict). Using non-ANSI compilers that implement the ANSI
|
||
features it uses will not work (unless they defined <code>__STDC__ 1</code>
|
||
which they shouldn’t). Due to space restrictions, I did not use
|
||
any trigraph sequences. It does not require any special <code>-D</code> defines.</p>
|
||
<p>The source passes lint without any complaint (if invoked with
|
||
<code>>/dev/null</code>). (My lclint is unable to recover from some parts of it.)</p>
|
||
<p>Actually, the code not only is compliant with the ANSI specifications, but uses
|
||
a near minimum subset of them. C keywords that were not used have been
|
||
re(de)fined to avoid unnecessary introduction of new, unknown character
|
||
patterns. The source also includes all ANSI headers it needs (after most of the
|
||
functions have been used), and the declaration of <code>main()</code> follows the
|
||
guidelines (but the return type has a different meaning and the arguments are
|
||
either misused or unused). There also may be some compiler warnings. These are
|
||
not bugs, but features. The more warnings, the better the compiler. There
|
||
wouldn’t be any if I had been allowed to use some extra space for prototypes
|
||
etc.</p>
|
||
<p>Multiple defines are used (but not all of them define), and <code>#define y define</code> is used with <code>#y</code> but the code doesn’t assume <code>#y</code> to expand
|
||
to <code>#define</code>. I have also included comments in the code, and vital
|
||
code in the comments. And of course there is code that doesn’t do
|
||
anything but will crash the program if it is removed (just like
|
||
those comments I mentioned above). Additionally, since you said
|
||
you’d be preprocessing entries ignoring <code>#include</code>s I figured I should
|
||
use some more of them instead of other obfuscation methods. Did
|
||
I mention that preprocessed or beautified sources will crash or
|
||
hang your system? The program will also crash on non-ASCII machines.</p>
|
||
<p>The executable needs its source file present in the current directory
|
||
or, depending on your system, in your path. The name of the source
|
||
file is not hard-coded, <code>__FILE__</code> is used instead.</p>
|
||
<p>In the original version which was sent in to the contest, there were
|
||
some restrictions on the file name:</p>
|
||
<ul>
|
||
<li>The second letter had to be a lowercase <code>r</code>.</li>
|
||
<li>The third letter could never be a <code>+</code> or a <code>b</code>.</li>
|
||
</ul>
|
||
<p>Valid names would have been <code>pr4.c</code>, <code>pr.c</code>, <code>prog.c</code>, <code>brownie.c</code> etc.
|
||
My first private version would only run when compiled on a Friday.
|
||
I decided it would be better this way…
|
||
These restrictions have been removed for your convenience.</p>

|
||
<p><strong>If you want a greater challenge, don’t read any further</strong>:
|
||
just try to understand the program via the source.</p>
|

<p>If you get stuck, come back and read below for additional hints and information.</p>
|

<h3 id="how-this-entry-works">How this entry works:</h3>
|
||
<p>The following lines describe how this program works; if you don’t
|
||
want to know it at this time, please skip them. If this entry would
|
||
by some mistake win the contest, please do not rot13 this - I hate
|
||
rot13 spoilers since it is somewhat complicated on a Mac to
|
||
reverse them. Anyone out there should have enough discipline and
|
||
rot13 shouldn’t be required, really. After all, we are not children
|
||
anymore :-)</p>

<hr style="width:10%;text-align:left;margin-left:0">
|
||
<p>This paragraph is not part of the author’s remarks, but is a helpful
|
||
gift from the judges; if you read too fast to stop yourself, this should
|
||
give you enough time to stop, which you really need to do RIGHT NOW if
|
||
you don’t want to read the obfuscation information: we mean it.</p>
|
||
<hr style="width:10%;text-align:left;margin-left:0">
|
||
<p>The source file needs to be present because the words are read from
|
||
it. The wordlist is encoded within the source using a 24 entry
|
||
sliding dictionary where lowercase letters are offsets into the
|
||
dictionary, uppercase letters are new letters not yet in the
|
||
dictionary, and all other characters are ignored. The words are
|
||
spread over six lines in the source; decoding starts on a line
|
||
after a tab and a whitespace have been found, and stops on a newline.
|
||
The grin after the “Demonic Smiley” actually is one encoded letter
|
||
while the string is completely ignored; and the <code>cut</code> in “cut here”
|
||
is required while <code>here</code> is not.</p>
|
||
<p>“For extra credit”, explain why the words are sorted alphabetically
|
||
(because I extracted them from a dictionary :-) )</p>
|
||
<p>The file name had to fulfill the restrictions mentioned above
|
||
because <code>__FILE__+1</code> was used as a second parameter to <code>fopen()</code>. (It
|
||
essentially was <code>fopen(__FILE__,__FILE__+1)</code> ). This was an extra joke
|
||
that doesn’t exist in the released version.</p>
|
||
<p>You probably discovered that the <code>while(FILE)</code> in <code>main()</code> is not a while loop
|
||
but the statement that opens the file and initializes the dictionary.
|
||
Similarly, <code>int</code> and <code>signed</code> have been redefined (to save space, of course).</p>
|
||
<p>The main function (the guessing part) is between the last <code>#else..#endif</code>,
|
||
but still is declared before <code>main()</code>. The <code>5[O]()</code> in <code>main()</code> calls
|
||
this function. Similarly, most indexing operations have been
|
||
changed to this form and I tried to write each such operation
|
||
different.</p>
