Hi All
I have a doubt and want to be cleared I am using
As you can see the $rr contains the reference to the first element of the array , now as the definition say array contains the continuous memory location, so when I incremented the $rr with 1 so it should now print the value for $array[1]..
Please correct me if I am wrong.

io::lines5.18
IO::Lines(3) User Contributed Perl Documentation IO::Lines(3)NAME
IO::Lines - IO:: interface for reading/writing an array of lines
SYNOPSIS
use IO::Lines;
### See IO::ScalarArray for details
DESCRIPTION
This class implements objects which behave just like FileHandle (or IO::Handle) objects, except that you may use them to write to (or read
from) an array of lines. They can be tiehandle'd as well.
This is a subclass of IO::ScalarArray in which the underlying array has its data stored in a line-oriented-format: that is, every element
ends in a "
", with the possible exception of the final element. This makes "getline()" much more efficient; if you plan to do line-
oriented reading/printing, you want this class.
The "print()" method will enforce this rule, so you can print arbitrary data to the line-array: it will break the data at newlines
appropriately.
See IO::ScalarArray for full usage and warnings.
