It seems that you are trying to use the Ada terminology with regard to
C, which has its own terminology. And, by the way, its own standard.

As I have already pointed out some posts before, your recognized style
of discussing is to warp definitions indefinitely just to prove your
point, whatever it is.
The problem is - C has its own standard and that standard says *black
on white* that this is an assignment. The standard says so. Amen. End
of story. If you say something else, then you are going nowhere.

No. Assignment does not destroy anything and does not construct
anything. Especially in the languages that has no destructors and no
constructors. The standard says so.

Ironically, you got it wrong not only for C (by completely ignoring
its own standard), but you have even got it wrong for Ada (5.2/1):

"An assignment_statement replaces the current value of a variable with
the result of evaluating an expression."

No destruction and no construction is mentioned in this chapter. Not
even once.

And it would be surprising to see them there, because in Ada, as in C,
the identity of the mutable object is preserved across assignment.
Atomicity of the process is yet another story. You would have to
invent a lot of additional stuff up in order for your theory to be
self consistent.

> No, I am applying a typed language terminology.

Your own terminology? Destruction and construction are processes that
do not need to occur in order for the assignment to take place and
this has nothing to do with any given language being typed or not. You
are just making things up now.

We are going nowhere with this discussion.
