There is an alternate version which uses fgets(). See the Alternate code section below as well as the bugs.md file for more details as to why it is worth having as an alternate version.

To run:

./hague 2>/dev/null
# enter some text

Try:

./hague 2>/dev/null
IOCCC
International Obfuscated C Code Contest
Jim Hague

Also try:

echo IOCCC | ./hague 2>/dev/null

Alternate code:

Whereas with some entries the change to fgets() (see the FAQ for details on why this has been done) can be done in the original code this entry is more complicated in that although both forms of input show the correct output, one form segfaults after the output.

If you wish to use this alternate code, do:

make alt

Use hague.alt as you would hague above. As for which form will segfault after outputting the text it is when text is piped into the program. Again see the bugs.md file for more details.

Judges' remarks:

Compile this program and feed ASCII text into standard input. This program is known to pass lint on some systems and abort lint on others.

This program was selected for the 1987 t-shirt collection.

Think Morse code when you ponder this program. Note how the use of similar variables can be obfuscating! The author noted that this program implements the international Morse standard. Now for extra credit, what Morse message does the program spell out?
