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.

Try with the following program.
[code]
sub sample
{
my @arr=(1,2,3,4);
return @arr;
}
my $c=(&sample)[2];
print $c;
Variable 'c' will contain the value '3'.

# Here is another solution
use strict;
sub sample {
my @arr = (1,2,3,4);
return \@arr; # return the array reference
}
my $aref = &sample;
print $aref->[2];
