How do I change this to “idiomatic” Perl?

Question

I am beginning to delve deeper into Perl, but am having trouble writing \"Perl-ly\" code instead of writing C in Perl. How can I change the following code to use more Perl idiom

Answer 1

One simple change is to use for loops like this:

for my $i (0 .. $num_of_rows){
    # Do stuff.
}

For more info, see the Perl documentation on foreach loops and the range operator.
