All good, it's working now after I've initialized the values :) the output is all the phone models in Uganda with the number of users having these phones. However, there are duplicates of models, with different values. Can you think of a way to add those values and have a unique model with all the values added up?
#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;
open (IMEI, 'IMEI.txt');
open (TAC, 'tac.txt');
my %mapToModel;
my %keyCount;
my $key;
my $model;
my $subs;
my $keyCount;
my $mapToModel;
my $count;
my %dictionary;
while (<TAC>){
$key = substr $_,0,8;
$model = substr $_,9;
$keyCount{$key} = 0;
$mapToModel{$key} = $model;
}
close (TAC);
while (<IMEI>){
$subs = substr $_, 0, 8;
if(exists $keyCount{$subs}){
$keyCount{$subs} = $keyCount{$subs} +1;
}
}
close (IMEI);
foreach my $key (keys %keyCount){
if (exists $mapToModel{$key}){
$model = $mapToModel{$key};
$count = $keyCount{$key};
foreach my$model (keys )
if( $count !=0){
print "$count\t$model";
}
}
}
