Perl giving errors on array reference

Question

Could someone explain how to correctly reference the arrays @names and @numbers. Currently I am getting warnings saying that using @names->[$count] is deprecated. I've looked around and people said to do $names->[$count] however when I do this it says that $names / $numbers does not exist.

my $ldap = Lib::Phonebook->new();

my (@names, @numbers, $count, $name_number_count);

    @names             = $ldap->list_telephone_account_names();

    @numbers           = $ldap->list_telephone_account_numbers();

    $name_number_count = @names;

    $count = 0;

    for $count (0 .. $name_number_count) {
        print @names->[$count] . " -> " . @numbers->[$count] . "\n";
    }

@names is an array, so to access an element you would use $names[$index].

Also, iterating from 0 .. $name_number_count will take you over the end of the array. You want 0 through "the last element index in @names" which would be @names - 1 or $#names. So:

for my $count (0 .. $#names) {

Perfect thanks! just noticed I'm now getting this: Use of uninitialized value within @names in concatenation (.) is this as a result of using this or something unrelated? Just seen your edit, thanks a lot that's sorted it
