What exactly is grooving and shortening of the array?
Consider the following example #! /bin/perl use strict; sub sample { my @arr=(1,2,3,4); return @arr; } my ($a,$b,$c,$d) = &sample; print "$a\n$b\n$c\n$d\n"; In the above code, How can I get the $c without using the arguments such as $a,$b. I don't want to use any array to get the return values.
