Code off

Name: Anonymous 2009-07-28 13:59

Welcome to the first annual /prog/ Code off !

The language will be C.

Compeptitors include (in no particular order):

Mr. Ribs
Xarn
FV
Anonymous
W. T. Snacks

Rumor has it, that there may be a special guest appearance from either The Sussman or
Leah Culver.

What's the point of this, you ask?

It's to determine who is an EXPERT PROGRAMMER.

Marking criteria:

Optimization
Elegance

Bonus marks:
indentation

Good luck!

K&R might have the concepts needed for successful C, but the style is pig disgusting. It doesn't surprise me that people that aren't interested in succeeding in C don't read it.

Do they impose their style on you? No, they don't; just pretend it's Allman or some variation thereof.

By this thread I conclude that 2% of /prog/ users can write real code.

Official Winner of Stage 1

+--------------------------------------+
Official Code Off: STAGE 2

2D Graphics

This is the second of three challenges. To complete this stage you must program a 2D graphical application that initializes a new 'Square' on the screen each time the user left-clicks. Each square will move at a constant speed in a random direction. Upon contacting a window border, the square will bounce off and continue in a new direction.

Each contestant has 24 hours to complete. Code must be posted in this thread by 4pm eastern tomorrow. This stage is slightly easier than the first, so I expect more than one legitimate entry!

You know what type of program I would like to see?  A recipe index where you can take different formats from various websites, conversion, grocery list, pictures, etc.

I wonder what would happen if Leah Culver and The Sussman both submitted entries. I wonder who's would win... The Sussman represents old fashioned, classical, elegant programming and Leah Culver represents fast paced, cutting edge, enterprise programming. It would be a monumental event.

I'd go with Culver if it was in C. Especially if it wasn't a math based problem.
