I am just starting out with Perl and I am reading the 6-part tutorial on perl.com. I am working on their first exercise which is a word frequency counter and I am stuck. I'm reading the array or words into a hash and the hash values seem to be correct but I am having trouble formatting the report. Thanks in advance for any help.
use strict;
use warnings;
my(@phrase) = ("apple", "apple", "banana", "banana", "pear", "pear", "
+pear", "kiwi", "kiwi");
my($i) = 0;
my($j) = 0;
my(%wordfreq) = ();
for $i (@phrase) {
$wordfreq{"$phrase[ $j ]"}++;
# print "$wordfreq{\"$phrase[ $j ]\"} appears $wordfreq{\"$phrase[
+$j ]\"}\n";
$j++;
}
print keys %wordfreq;
print $wordfreq{"apple"};
print $wordfreq{"banana"};
print $wordfreq{"pear"};
print $wordfreq{"kiwi"};
