C is a little more vague and hides the details. typedef void (*ptr)(); int HHH(ptr P); // simulating termination analyzer void DDD() { HHH(DDD); return; } Each HHH of every HHH that can possibly exist definitely emulates zero to infinity instructions of DDD correctly. Every expert in the C language sees that this emulated DDD cannot possibly reaches its own "return" instruction halt state. Every rebuttal that anyone can possibly make is necessarily erroneous because the above paragraph is a tautology. HHH computes the mapping from its finite string of x86 machine code to the actual behavior that this finite string specifies which includes recursive emulation. -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
