Struct's Unions and Enumerators... Pointers... I finally realized they were a LOT more complicated than values and addresses... Still makes me "Slightly Crazy"
and I force myself to read 2 hours a day...

I started programming with C in around 1990.
I only truly got to grips with pointers and such about 5 years back. I still get confused by them sometimes even now.
Having come from a hardware machine language background the concept of pointers were very simple to me. Pointers are just variables that contain memory addresses rather then containing data values directly. Indirect addressing used in machine language is the same concept. The inclusion of pointers in the original C language is one of the things that made C such a powerful 'low level' language and could compete with assembly language. That being said, I have had no use to actually use pointers in any of my arduino sketches so I would most likely trip up badly actually trying to utilize pointers successfully.
