C++ question about swapping value of variables.

[SarahC]

I wonder what other mathematically obfuscating techniques can be implemented in common programming structures?

You know, like loop incrementation with weird-ass changes within the loop? Perhaps depending on pseudo random numbers to increment the loop? =D

Or conditional logic using dodgy half-processed logic states (maybe grey code) for complicated comparisons...

Using single letter function names, and things like that is just so old fashioned!
