<p>By changing the compile line you can make this program do anything

you want. This is a very efficient way to transfer source, though it

increases the size of Makefiles.</p>

<p>With only slight variations, this program can be set to many uses.

Consider how easy it would be to release Un*x source in this form; so

what if the make files grow a little! :-)</p>

<p>FYI: We will let Mark get away with this truly sick entry this time,

<p>This program was designed to maximize the bother function for

structured programmers. This program takes goto statements to their
|

logical conclusion. The layout and choice of names are classic.</p>
|

<p>We consider this to be a beautiful counter-example for Frank Rubin’s
|

letter to ACM form titled: <em>“GOTO Considered Harmful” Considered

<p>1987 marked the “The Fourth International Obfuscated C Code

Contest”</p>

|
||||
<p>The rules for 1987 suggested even more categories than in 1986. Hints
|
||||
for what to do and not to do were also given in the rules. For example,
|
||||
a simple excessive abuse of /lib/cpp was discouraged unless the abuse
|
||||
was unusual. The mailboxes for the contest were moved from nsc to
|
||||
amdahl. The practice of posting a preliminary set of rules for the next
|
||||
year was started this year.</p>
|
||||
<p>Rules and results were posted to comp.lang.c, comp.unix.wizards with
|
||||
an announcement in news.announce.important. Micro/Systems Journal
|
||||
published the 1987 winners. Mark Horton included a version of the 1987
|
||||
winners in an appendix of his C book. The first announcement of winners
|
||||
at the Summer 87 Usenix was helped by a small fly that danced all over
|
||||
the foils.</p>

<h2 id="judges-comments">Judges’ comments:</h2>
|
||||
<p>The Judges believe that this is the best one line entry ever
|
||||
received. Compile on a UN*X system, or at least using a C implementation
|
||||
that fakes it. Very few people are able to determine what this program
|
||||
does by visual inspection. I suggest that you stop reading this section
|
||||
right now and see if you are one of the few people who can.</p>
|
||||
<p>Several points are important to understand in this program:</p>
|
||||
<ol type="1">
|
||||
<li><p>What is the symbol ‘unix’ and what is its value in the program?
|
||||
Clearly ‘unix’ is not a function, and since ‘unix’ is not declared to be
|
||||
a data type (such as int, char, struct foo, enum, …) what must ‘unix’
|
||||
be?</p></li>
|
||||
<li><p>What is the value of the symbol “have”? (hint: the value is NOT 4

|

</ol>
|

<p>defines a pointer to a character (i.e. an address), and that the ‘=’

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>We believe that you too will be amazed at just how much power
|
||||
Mr. Lievaart packed into 1024 bytes!</p>
|
||||
<p>This Plays the game of reversi (Othello)! Compile and run. It then
|
||||
asks for a playing level. Enter 0-10 (easy-hard). It then asks for your
|
||||
move. A move is a number within 11-88, or a 99 to pass. Illegal moves
|
||||
(except for an illegal pass) are rejected. Then the computer does its
|
||||
move (or a 0 to pass), until the board is full.</p>
|
||||
<p>It plays rather well, for such a small program! Lievaart had to leave
|
||||
out the board printing routine, so you’ll have to take a real game board
|
||||
to play it. … Also due to space-limitations (the rules for 1987 had a
|
||||
limit of 1024 byes), Lievaart took out the passing-handler, which makes
|
||||
its ending-game rather poor. But further it knows all the rules, uses
|
||||
alpha-beta pruning, and it plays f.i. on mobility(!). Most important: it
|
||||
can play a pretty good game of Reversi!</p>
|
||||
<p>The Author was kind enough to supply the fully functional version of
|
||||
the program. The file lievaart2.c contains what the program would have
|
||||
been without the size restriction. This version has the full end game
|
||||
logic and displays the board after each move!</p>
|
||||
<p>NOTE: This entry requires a non-standard K&R C compiler to
|
||||
compile.</p>

<p>What we found amazing was how the flow of control was transferred
|
||||
between subroutines. Careful inspection will show that the array of
|
||||
pointers to functions named ‘vi’ refers to functions which seem to not
|
||||
be directly called. Even so, these pointers to functions are being used
|
||||
as an argument to signal. Can you determine why this is being done and
|
||||
how it is being exploited?</p>
|
||||
<p>Some compilers complained about this file, so we changed: ‘=++I’ to
|
||||
‘= ++I’.</p>

|

<p>Putchar must exist in the C library and not just as a macro. If it
|
||||
fails to compile, add the line: <code>#include <stdio.h></code> at
|
||||
the top of the program.</p>
|
||||
<p>Line by line symmetry performed better than any C beautifier. Think
|
||||
of if it as a C ink blot. :-)</p>
