The subroutine you've written takes an array, not a reference to an
array.
To call it use printarray(@flintstones); alternatively recode it as
Sundara Rajan suggests to take a reference to an array. Note
there is no real need to use a reference in this case, it might be
faster, I don't know.
Personally, I only use references to arrays when more than one
must be passed to a subroutine.
