I can't really ever tell the difference just by looking   :P

.... a single source.  a .c file and then do a gcc compile to make a ... .bin?
..exe?

this one:

I have never "built" anything from scratch, so I really have no idea what I'm
doing or why.

Sure, whatever.   but that guy's code is redundant to the gsl library.  If I've
already installed that - isn't that ... built? (*)

I used to write a bunch of stuff for different Arduinos - ATMega and Leonardo...
 still some confusion as to whether that's C or c++


But I'm sure I could learn.  I _would_ rather stick with one language, to
minimize confusion, and if POV-Ray source is in c++, then I'd prefer that, but
I'm sure one translates over to the other to some extent.

 The GNU Scientific Library (GSL) is a collection of routines for
 numerical analysis.  The routines are written from scratch by the GSL
 team in C, and present a modern API for C programmers, while allowing
 wrappers to be written for very high level languages.
