Hello, I am having a problem doing a simple array comparison. I know that I probably should have used a hash to do this but I would rather stick with the array approach just because I am not sure of what is wrong with it....Any how, basically I got 2 txt files that I want to compare and have a list printed out of the ones that are not in one of the lists when the script is done. The master list is the list of all possible numbers/codes and the compiled list is the ones that I have already done and want to rule out. I would like the final result to be a list of the numbers that were in the master list but not the compiled. I have posted my code. Thank you in advance. Any advice or feedback would be greatly appreciated!
#!/usr/bin/perl
use strict;
use warnings;
#open master list
my @masterCodes;
open(MASTER,"<master.txt") or die "Couldn't open file 1: $!\n";
while(<MASTER>)
{
chomp();
push(@masterCodes,"$_");
}
#open compiled list
my @compiledCodes;
open(COMPILED,"<compiled.txt") or die "Couldn't open file 2: $!\n";
while(<COMPILED>)
{
chomp();
push(@compiledCodes,"$_");
}
my $totalSize = $#masterCodes;
my $i = 0;
foreach my $code (@compiledCodes)
{
while ($i < $totalSize)
{
if ($code = $masterCodes[$i])
{
print "$code\n";
}
$i++;
}
}
