Re: HOW Can I pass the array into my subroutine?

I'm a fan of Params::Validate. It's a great module that help you deal with lack of parameter checking in Perl.

This is how you declare your module with it:

use Params::Validate ':all';

sub sortArray
{
    my ($unsorted) = validate_pos(@_, { type => ARRAYREF });

    my @sorted = sort @{ $unsorted };

    return @sorted;
}

And this is how you can use it:

my @unsorted = (9, 4, 2, 6, 1);
my @sorted = sortArray(\@unsorted);

You can also use it's validate method for named parameter if your subroutine is likely to get bigger

Hi Perl Monks! I posted a message here was because I didn't find any reference in my reading book that mentioned about passing an array as the argument into the subrutine. And i was writing a perl script, which will do exactly what quick sort does. In this script i need write some subrutine as my functions..there is no extra trouble here... Anyway, I got all answers I wanted from your great replys. Thank you!!	[reply]

note that sort does exactly what quick sort does (for some versions of Perl anyway). Unless you are doing this as a learning exercise Perl's built in sort is generally a much better choice than rolling your own. DWIM is Perl's answer to Gödel	[reply]
