>>anywhere (not just in a header file) it's a definition and it's tentative.
nothing is tentative in the C paradigm unless you have created your own . there is absolutely no confusion about the fact that unless a header file is included in a C file a declaration never gets into a definition as it doesn't still have a memory allocated....Leave a comment:

so as I do ..... and just one more information when you are talking about a header file it's always declaration not definition .... until the header file is included in a C/C++ file it never gets it's memory allocated ... so it's a declaration in a...Leave a comment:

and you don't want multiple copies of your static variable... right ? why does one in the first place declare a variable as a static variable in a header file ? one can only do that assuming this would be unique across the compilation units and so ( by mistake of course). but otherwise there can be no sesible reason on wants to declare something as static in a header file. that's...Leave a comment:

a static variable defined in the global space in a file cannot be accessed from other files because it doesn't have an external linkage. the example I have given exactly says that. look below for once again:
/*Illegal use of static variable*/
/*File: test1.c*/
#include<stdio. h>
#include "header.h"
int i = 100;
