Regarding the unwanted items in your report: There are three general ways to approach it:
- Remove unwanted characters before counting,
- Delete them after counting but before reporting, or
- Delete or ignore them during the report.
Each method has situations where it is better than the others, but frequently any of them are good enough. Examples:
# Case 1: don't count unwanted characters
for my $char(@letters) {
++$charCount{$char} if $char !~ /[a-zA-Z]/;
}
# Case 2: delete unwanted characters
my %t = %charCount;
$t{$_}=$charCount{$_} for grep {/[a-zA-Z]/} keys %charCount;
%charCount=%t;
# Case 3: ignore unwanted items during report
for my $char (sort keys %charCount) {
next unless $char =~ /[a-zA-Z]/;
# print report entry
}
