TIMTOWTDI (and not quite redundant):

This alternate also works:

#!/usr/bin/perl
use 5.016;
use warnings;

# 1048190

my @arr = ("Hello, my name is John",
           "How are you?",
           "blah (blah)",
           "",
           "blivitz is in the last line.",
          );

my $count = 0;

for my $line(@arr) {
    say $count . " " . $line;
    $count += length($line);
}

Producing:

C:\>1048190.pl
0 Hello, my name is John
22 How are you?
34 blah (blah)
45
45 blivitz is in the last line.

Use of printf or sprintf is left as an exercise for the OP... altho the initialization of $counting = '00000000'; should be satisfactory too.

If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post.
