Thread: static variable result

Does this confuse you less?

Code:

#include<stdio.h>

static int i = 0;

void foo ()
{
	    printf("i = %d \n", i);
	    i = 1;
		printf("i = %d \n", i);	 
	    i = 2;
		printf("i = %d \n", i);	
		i = 3;
		printf("i = %d \n", i);	
}
int main ()
{
	foo ();
	printf("\n");
	foo ();
	return 0;
}

The only difference here is that the variable called i now has a scope that extends to the whole file, and not just the foo() function.
