No it can't. It can be hidden from direct access from an outer scope or
from another translation unit, but nothing anywhere in a C program's
address space can be absolutely protected from any other part of
itself.

Maybe you can clarify your question?

"He" is wrong. C does not have these features. Compiling code that is
/claimed/ to be C with a C++ compiler doesn't make it true.

C has no "private" or "protected" or "public" scope.
Are you thinking of some other language?

No. There are no scopes private, protected and public in C.

You are looking for C++. And C++ cannot really protect (as in
prevent access) either. The protection only works if everyone obeys
the rules. All you have to do is invoke the wrath of undefined
behavior, often by loading up a pointer with something illegal, and
then using it.

In C There is no Private, Public,protecte d so there is no case of
protection.
in C++ There is Private ,Public Protected. If you follows rules it is
protected . if you are not following you still can access Private Data
even in C++.
