The title should really state that this is a minimal x86 assembly tutorial written from a C programmer's point of view. It isn't so much about how C gets converted to assembly as it is about how some C structures might get compiled on an x86 system. If it was about
how, it would go into the differences when optimization flags are set, how the resulting assembly code might look nothing like the C source at all, etc, since compiling those same snippets on C won't always produce the code provided even if you only stick to an x86 system with no compiler options set.
Now what would be really cool is to write a second article following the exact format, but covering something like a RISC chipset (Raspberry Pi et al). The comparisons would be quite interesting, and then the title would more closely live up to the wording. And include the different optimizations with it, as well.
