Hello all, newbie here got a few questions:
I am working with pointers and I sort of understand them and then I
don't. I understand that instead of making a variable for a particular
value you can use a pointer to access the same data. So the new
variable stores the pointer to the old data.
ie.... $a = "mom";
$b = \$b;
print $$b --> mom
Ok so what I don't understand is when do I need to dereference the
pointer for hashes. so I have a hash pointer.. \%overData. Now how do
I access this hash. %$overData?
Thanks
confused.
