About this subtrack

x86 Assembly (Intel syntax) teaches the language your CPU actually executes on common PCs. Hello world via syscalls, loops in registers, System V calling conventions, stack frames, and debugging habits show up as tasks with expected outputs.

If you have only seen assembly as compiler output, this subtrack forces you to write it. Pair with C Programming so you can map high-level constructs to instructions. Primary intent: "learn x86 assembly hands-on" and "calling convention tutorial."
