Sort of. If you include stddef.h then you are writing C and there are no
namespaces. If you intend to write C++ then you ought to include cstddef
instead. Yes, you can get away with including C headers in C++ but its
handly best practice.
Well, I wasn't really referring to /writing/ C++ code.
Besides that C++ for a long time didn't have namespaces ;-) nor headers
*not* ending with .h, actually a couple of .h headers *were part of the
C++ standard* (but are deprecated now, in preference of their c*
replacements). So, depending on the C++ standard you're using (or, in
other words, some existing code was written for), including a .h header
doesn't necessarily mean you're including a "plain" C header; it may be
a ("fixed") version provided by your C++ compiler.
