I think it's best to start with assembly language, without
pre-processor macros, micros and such, to begin. It's more
genuine. There's less clutter. Pointers are just
addresses. You can add off-sets to a base address, etc.
Unfortunately, Intel assembly languages are kind of messy,
too, but still worth the effort because it builds a solid
foundation for understanding all of the languages layered
on it.
C is close enough to the processor to learn how it works. And Intel
assembly language is a mega sucker. From the standpoint of learning
4040, 8080, 8051, 8096 and 8086 assembler after writing apps in DBase,
Basic, C, 1st gen C++, 68k assembler and debugging PPC assembler.
The problem with messing with pointers in C, C++ and
Objective-C is that the notation is messy and not
suggestive of what's going on.
A good tutorial will take care of that. And except for image and raw
data manipulation, pointer arithmetic is sooo 90ies, read: obsolete.
