The const qualifier used on a declaration of a non-local non-volatile
non-template (since C++14) non-inline (since C++17) variable that is not
declared extern gives it internal linkage. This is different from C
where const file scope variables have external linkage.
Interesting, thanks.
But it doesn't make sense to me. I've always understood 'extern' has
'defined somewhere but not here'. In other words 'extern' must be
part of a declaration, and not of a definition as that would be
a contradiction in terms.
Ciao,
