Subroutines vs. Functions
2025-05-29
TL;DR
CPUs implement subroutines at the hardware level, not functions in the mathematical sense.
Subroutines and functions are both reusable blocks of code, but they differ in a key way: return values.
In C, there isn't technically a separate "subroutine" construct - everything is a function.
Computer Science is fundamentally about mathematical functions and computational processes, not CPUs specifically.
