The problem is the single quotes I think.
Try double quotes.
Also are you actually hardcoding the strings in there or getting them from input?
If 'from input' try this:
use CGI qw(:standard);
my $string = param('string');
And feed it input of I love c++ as the string paramater and
that'd be a more acurate test of the regex in actual usage conditions.
C:\SCRIPTS\test>perl lovec.pl 'string=I love c++'
See how that comes out.
