I have a very basic query on finding number of elements in an array from array reference.

    my @sss = ("1","3","4");
    my $reee = [];
    for $entry (@sss){
    push (@$reee, $entry);}
    my $asdad = length @$reee;
    print "$asdad";

Assuming, I don't know number of elements in @sss, How to find number of elements form @$reee.

Command "length @$reee" returns value 1, which is right, because it is a scalar. But I want to obtain result as 3. How to get it ?

Update: got it ! Array reference (@$ree) should be considered as array.

 my $asdad = @$ress

in line line 5 of code will give correct result !

Thanks every one
