Hi everybody,
I am a beginner of programming ( so I am a beginner of perl programming
too :-) ) and I have this very basic problem but cannot handle it.
I'm trying to match only a one single digit and wrote this code:
use strict;
my $number = 11; # two-digit number
if ( $number =~ /\d{1}\b/ ) {
print "Match\n";
} else {
print "No Match\n";
}
But I get a match !?
I also tried:
$number =~ /\d?\b/
because ? stands for no or one character
But that didn't work either.
Can someone give me a hint and maybe a source for more
basic dokumentation about reg exp.
Thanks for your time and have a nice day
