Landon Curt Noll a1c86c8a7a add original C links to entry navigation bars
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.

<p>Some terminal applications do not handle all Unicode characters adequately.</p>
<p>On Linux, it is better to enjoy this entry on <code>gnome-terminal</code> or an equivalent modern terminal emulator.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
<p>We had a few minutes of amazement and fun while figuring that the is
something fishy 🐠 wit the <a href="https://github.com/ioccc-src/winner/blob/master/2024/cable2/prog.c">prog.c source code</a>.</p>
<p>Those who follow the philosophy of “<em>seeing is believing</em>” are
likely to be “<em>deceived</em>” when they try to view the
<a href="https://github.com/ioccc-src/winner/blob/master/2024/cable2/prog.c">prog.c source code</a> in a terminal window:</p>
<pre><code> cat 2024/cable2/prog.c</code></pre>
<p><strong>HINT</strong>: There is a command line flag to the <code>cat(1)</code> tool may provide a clue.</p>
<p><strong>HINT</strong>: For those who might not be familiar with the
<a href="https://en.cppreference.com/w/cpp/language/string_literal.html">U”string” literal prefix</a>:
When using the U literal prefix, anything inside the quotes is encoded as <strong>UTF-32</strong>.</p>
<p><strong>HINT TO FUTURE SUBMITTERS</strong>: Now that we have awarded
this <strong>clever entry</strong>, please understand that this
<a href="https://en.wikipedia.org/wiki/Salmon_hat">salmon is now old hat</a>.
What was <strong>murky waters</strong> for <strong>IOCCC28</strong> in 2024 will, in the future,
be immediately seen through when analyzing future submissions to the IOCCC.
In other words, to win a future IOCCC, you will need to do <strong>MORE</strong>
than simply employing this fun obfuscation trick! :-)</p>
<h2 id="authors-remarks">Author’s remarks:</h2>
<p>Salmon: a most fishy submission</p>
<h4 id="about">About</h4>
<p>This program obviously prints the squares of the numbers from 1 to 10. Or does it? The author got a little hungry for char-grilled salmon, and there’s clearly something fishy going on with those unused #defines. Or is there? What the actual f*sh is going on here? Follow the three steps below for maximum enjoyment.</p>
<p><strong>Step 1:</strong></p>
<pre><code> cat prog.c</code></pre>
<p><strong>Step 2:</strong></p>
<pre><code> make clobber all</code></pre>
<p><strong>Step 3:</strong></p>
<pre><code> ./prog</code></pre>
<p>Scratch head. Then, <a href="https://www.youtube.com/watch?v=T8XeDvKqI4E">slap head with fish</a>.</p>
<p>You may suspect there’s something fishy with the <code>Makefile</code>, but you would be wrong. It just invokes <code>cc -o prog prog.c</code></p>
<p>You may suspect <code>cat</code> might be eating the salmon in step 1 (see <code>2015/endoh2</code>), but you would be even wronger. Confirm by looking at the program source using GitHub or <code>emacs</code> or <code>nano</code>.</p>
<p>You are probably now even more confused, in which case, return to step 1.</p>
