the length function returns the length (in bytes), your code is fine but you haven't chomped the new-line character (\n) which is embedded into the string the moment you press the return key.

The Return key press would be treated as part of the input and you have to trim it using chomp before going further. chomp after the 7th line worked just fine for me!!! 

use strict;
use warnings;

print "Enter the string =";
my $str = <STDIN>;
chomp $str;
print "Enter the size =";
my $n = <STDIN>;
chomp $n;
