Question...
I have not been able to post here for quite a while, mainly due to lack of time. So thought of updating the blog with a question that I heard today. Its technical of course ;-)
Write a program to find out if the system stack is growing from higher address to lower address or from lower address to higher address... Pretty simple actually, but worth a shot.
Send your answers to me by mail (mailto: thisisgiri@gmail.com) and I will publish the answer after a couple of days...
P.S: This is very simple, and hence there are no prizes for cracking it ;-)

Like I said, this one was pretty simple. All you had to do was compare the addresses of local variables from 2 consecutively called functions. As in:
int * bar()
{
int x;
return &x;
}
void foo()
{
int x;
int *px = &x;
int *py = bar();
/* (px > py) ? Higher to lower : Lower to higher */
}
int main()
{
foo();
return 0;
}
Incidentally, HP on PA_RISC seems to be the only case that I have seen where the stack grows from lower address to higher address. Most others like AIX on PowerPC, Solaris on SPARC and Linux on x86 all seem to grow the stack from higher address to lower address.
