Perl's length function

Why would perl's length function add an extra character in its result?

I have this simple code.

#!/usr/bin/perl
print "enter text ->";
my $variable;
my $variable = <>;
$length = length($variable);
print "$length\n";

But when I enter the text "hi" for example, the output of length is 3, while I'm expecting it to be 2.

The newline at the end of the input is part of the value. Remove it with chomp:

my $variable = <>;
chomp $variable;
print length $variable;

Also, use warnings to be notified of duplicate declaration of $variable.
