why did you think that? I just wanted to show you a case where an uninitialized pointer actually is initialized. That was all.
I didn't imply that I use only global variables...

Previously you said, I'm quoting: "and pointer declaration depends on the compiler (but you are right it should be undefined)". But Now you say they are initialized...

How can "uninitialized pointer" be actually "initialized". There is no such thing as global unitialized variable from users point of view. C standard requires all global variables to be initialized to 0 or by calling C++ constructor.
