You can't. The above should produce a compile error. You're trying to
create an array that has no size.

Use it for what?

Which C++ book(s) are you reading?

In turbo C++ from Borland Version 1 1990, a .c file raised a compile
time error while a .cpp file didn't. Is this up to the Compiler used?

If you have a question that is not related to a thread, please don't
post it as reply to it.
