Just to be explict. You do realise that the fact Zero is returned as the first key has nothing to do with the order of insertion?

All of these print "Zero" on my build of perl (5.8.7)

my %hash = ( "Zero" =>"0", "One" => "1", "Two" => "2", ); my @array = keys %hash; print $array[0] . "\n"; -------------------------- my %hash = ( "One" => "1", "Zero" =>"0", "Two" => "2", ); my @array = keys %hash; print $array[0] . "\n"; -------------------------- my %hash = ( "Two" => "2", "One" => "1", "Zero" =>"0", ); my @array = keys %hash; print $array[0] . "\n";
As a Perl programmer you should never write code which relies on the order returned by keys/each (apart from it being the same as the list time you checked, if you’ve not updated the array).
my name's not Keith, and I'm not reasonable.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
