Akshully, there are more levels below the machine code, with the mind-boggling complexity of modern CPUs and SoCs - but that doesn’t diminish the value of understanding it.
That’s why I said “modern.” You know exactly what’s happening on a MOS 6502, for example, but when your top-of-the-line ARM SoC starts throwing bus faults because a CRC function returned a value that looked like a pointer to restricted SRAM …

To learn more, attend my upcoming CEC course January 27-31: Expert C Techniques to Master Bare-Metal Programming. You’ll discover how to master one of C’s most powerful tools—function pointers—and use them to design flexible, efficient systems. From building cooperative schedulers and command parsers to creating configurable, reusable code, you’ll gain hands-on insights that can transform your approach to embedded programming.

Depends on what CPU is getting used but it’s really fascinating.

…yep, sounds about right.
Aren’t function pointers against the MISRA standard?
I’m not saying they are bad because they can be really useful but when it comes to writing safe code I believe their usage is heavily discouraged
