I have some confusion in the last case you mentioned. From my understanding what "# include somefile.h " will do is basically paste the entire section of that header file there. So basically you will have definition and an extern decleration of the same variable in the same file right ? so .. do you really need extern in this scenario ?? .. kindly post if I am wrong.

In the 3rd case what will happen if we write
extern int var = 0;
...?
I think the memory will be given to the var variable and it will work fine?
