Hello,
Here you are right about variable p in add function that it retains it's
value even though function loses its scope. And for main function error you
are seeing has nothing to do
i think guys are confuse between scope of variable and lifetime of
variable.
p scope is add function and lifetime of p is till the program run.
so u can't access variable outside the scope of variable whatever is the
lifetime of variable.
u can look at peter ven den linden Deep C secrets.

I think rahul has given a clear solution i.e why the static variable is not
accessible in main() function because of its scope.
I would like to add one more point in this...that Static variables may be
initialized in their declarations;
however, the initializers must be constant expressions, and

thanx for the explanation..

void add(int,int);
int main(int argc, char *argv[])
{
add(6,3);
printf(%d,p);
system(PAUSE);
return 0;
}
void add(int a, int b)
{
static int p;
p = a+ b;
}
here the memory layout says variable p is in BSS segment ... so
I think you are right about p being in BSS segment and it does last even
the function finishes, however, you may need a pointer to get the data out
of p. Then you can read the data.
Correct me if i am wrong

Hello,

It is about the scope of that variable C compiler sees the scope of static
