To build:

make

To run:

./prog < input > output

Try:

echo Hello | ./prog > hello.c
make hello

Selected Judges Remarks:

If you look closely at the source, you will see code that appears to puts C code that includes itself. How and why? Perhaps it is in the DNA code of the code? Perhaps there are 23 reasons? :-)

Remarks

This chromosome program synthesizes a double helix. The helix can also be compiled as a C program.

Enjoy DNA programming!

For more information / backgroud reading:

This program was inspired by Acme::DoubleHelix: http://search.cpan.org/~xern/Acme-DoubleHelix-0.01/
The synthesized helix just includes the original program at the head. Do you see how prog.c determines whether it was invoked as a standalone program or included as a header file? Note that it does not use any gcc extension such as __INCLUDE_LEVEL__.
The synthesized helix of course follows the base-pairing rules for DNA: A is bonding only to T, and C is bonding only to G.
