Hi Everybody,

Greetings!

I got surprised when the following program did not crash.

typedef struct _x{
int a;
char b;
int c;
}x;
main()
{
x *ptr=0;
char *d=&ptr->b;
}

As per my understanding the -> operator has higher precedence over & operator. So I expected the program to crash at the below statement when we try to dereference the NULL pointer tr.

char *d=&ptr->b;

But the statement &ptr->b evaluates to a valid address. Could somebody please explain where I'm wrong?

Thanks & Regards, Arun
