static struct in C/C++

Question

static struct K {  int x; };

Is this valid in C and C++?

Why not just try it and see? When you find out that it _isn't_ ask what your error is. — San Jacinto, Mar 05 '11 at 17:47
@Darin these days everyone who has access to internet has access to compiler: http://ideone.com/YqWd8 — Andrey, Mar 05 '11 at 17:50
I think it's a reasonable question. What one compiler accepts, another may reject, and this doesn't really help to work out whether it's valid C and C++. — , Mar 05 '11 at 17:55
@Brone In this case, wouldn't any reasonable C compiler accept it and any reasonable C++ compiler reject it? It's certainly a reasonable question; I just get tired of getting excited and then clicking on a link for a question the OP could have answered on their own in about 30 seconds. — San Jacinto, Mar 06 '11 at 19:59

In C, it's valid but useless.

In C++ it's invalid. You can only specify storage class for objects and functions.

Valid in C. Ill-formed in C++

In C++, specifiers extern/static can only be applied to names of objects or functions

No... That is not valid in C++. An alternative is (C++) : unnamed namespace

namespace 
{
   struct K {  int x; };
}
