Clarification on chomp

Question

I\'m on break from classes right now and decided to spend my time learning Perl. I\'m working with Beginning Perl (http://www.perl.org/books/beginning-perl/) and I\'m finish

Answer 1

I think best practice here is to write:

chomp(my $input = );

Here is quick example how chomp function ($/ meaning is explained there) works removing just one trailing new line (if any):

chomp (my $input = "Me\n"); # OK
chomp ($input = "Me"); # OK (nothing done)
chomp ($input = "Me\n\n"); # $input now is "Me\n";
chomp ($input); # finally "Me"

print "$input can be reached at $name_number{$input}\n"; 

BTW: That's funny thing is that I am learning Perl too and I reached hashes five minutes ago.
