Richard is wrong when he says that there exists an H/D pair such
that D simulated by H ever reaches past its own line 03.
Yes, in the same way that you are wrong. The above "C code" is garbage;
as already pointed out, it doesn't even compile. So any talk of
"reaching line 3" or "matching" that "code" is vacuous nonsense.

Since nobody knows who has verified this fact en there have been counter examples,

Before we can talk about this, first there must be 100% agreement about:

I am ONLY referring to expressions that are PROVEN

How do we know that 2 + 3 = 5?
If needed we can write out the proof for this, starting from the axioms for natural numbers. That proof is well known.

But nobody here knows the proof for your assertion above, that it is a verified fact that it cannot reach past line 03. So, we would like to see that proof. Just the claim that it has been proven is not enough.

Are you honest? Please, give the proof, instead of keeping away from it.
I have been an expert C/C++ programmer for decades.
If you knew C will enough yourself you would comprehend
that my claim about:

This is a simple software engineering verified fact.

Again no trace of a proof. Only your authority and personal attacks about lack of knowledge and ignorance. So, the text below still stands:
>
*The only sufficient proof is being an expert in C yourself*
Again no trace of a proof. Do you understand what a proof is?
The proof of 2+3=5 is not 'Being a mathematician'.
You give the impression that you are clueless about how to prove it.

The proof of 2 + 3 = 5 is through comprehending arithmetic.
No, it follows with very simple reasoning from the axiomatic properties of natural numbers.

do not understand them then the proof is impossible.

It cannot be proved to anyone failing to comprehend the semantics of C.
Since we understand C, that is not an excuse. It seems that you are looking for excuses to hide the fact that you have never seen such proof.

If you understand C and understand proofs then you
understand that a single counter-example would refute
my claim if one exists. You would also understand that
that when no such counter-example exists that would
prove that I am correct.
So I ask you to do one of three things:
(a) Admit that I am correct
(b) Provide a single counter example
(c) Admit that you simply don't understand this.
*Any other response will be construed as intentional deception*
Intentional deception certainly meets the requirement of
reckless disregard for the truth of defamation lawsuits.
