Answer / nischal bansal
Static global variable can be used only in the file, it is
declared whereas global variable can be used in other files
also. we have to include the file, in which we have
declared the variable

Answer / sheela
hello...
what r all above said is false. global static also can
access using extern in other files.
file 1:
#include<stdio.h>
#include <conio.h>
#include "file2.c"
int a=10;
static int b=20;
main()
{
send();
}
file 2:
#include<stdio.h>
#include<conio.h>
void send()
{
extern int a;
extern int b;
printf("%d%d",a,b);
getch();
}
this program prints both a and b values.. then how can u
say global statics has file scope.
please if anybody knows correct answer give me.
