Not at all, all languages are connected to assembly language in the sense
that you can write assembly language that corresponds to the semantics of
the language. How WYSIWYG the language is does indeed vary. C is very close
to meeting this criterion 100%, but that's a far cry from calling it an
assembly language itself. Of course I did not "deny any connection" with
asm. You did not read anything even vaguely saying that in what I wrote.
