Personally I prefer to convert all dates to an "offset from an epoch" and do all operations on them that way.
Only converting back to "display format" when I'm done.
Keeping in line with your basic logic I'd probably
parse as follows:
sub isGreater{
my $currDate = shift;
my $oldDate = shift;
my ($currMonth,$currDay,$currYear) = split /\//,$currDate;
my ($oldMonth,$oldDay,$oldYear) = split /\//,$oldDate;
return $currYear <=> $oldYear or $currMonth <=> $oldMonth or $currDa
+y <=> $oldDay;
}
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
