in reply to Comparing Arrays -> storing results in a third Array

Try...

#!/usr/bin/perl -w use strict; my @array_1 = ('a','b','c'); my @array_2 = ('x','y','c'); my $index1 = 0; my $index2 = 0; for ( @array_1 ) { # Reset the index of the second array because we're # going to read through it again $index2 = 0; my $element1 = $_; for ( @array_2 ) { my $element2 = $_; if ( $element1 eq $element2 ) { print "Index # $index2 of array_2 " . "($array_2[$index2]) = index # " . "$index1 of array_1 ($array_1[$index1])\n"; } $index2++; } $index1++; }
     This is probably not the most elegant solution, but I it will work.

Here's the output...
Index # 2 of array_2 (c) = index # 2 of array_1 (c)
