The biggest difference is that in C, you have to allocate memory before
you can point at something or you will get a null pointer exception, and
then deallocate the memory when you are done. Perl does this
automagically.

Careful -- use parentheses here, not braces.

I would suggest also, especially for beginners, to use the infix arrow
syntax -- it makes things a little clearer, especially when you get into
multidimensional arrays (and using references is the nly way to do so).
$array2[1]->[$x];
