Thread: Global and static global

Hi,

What is the difference between static and global static variable?
I am not able to find any differences. Well they both seem the same to me.
Do they differ in storage or the place where they are stored?

Code:

#include <stdio.h>

unsigned int a ;
static unsigned int b ;

int main(void )
{
printf("\nGlobal : %u and %u\n",a,&a) ;
printf("\nStatic Global : %u and %u\n",b,&b) ;
return 0 ;
}

Please explain me with an example.
