What is order of retrieving the values from Hash??
Hash data items are retrieved in the "natural" order in which they're stored in the hash. It's hard to say what that order is, but we know what it's not. It's not alphabetical order, and it's not the order that elements were stored into the hash. It's not random order, which might be nice, and it's not sorted by value, as convenient as that would be. It's not an order that is sure to be the same for every release of Perl, for every implementation of Perl, or even every time you run your program with the same perl binary on the same OS on the same day. It's not any order that's useful for anybody but Perl, in fact, so we may as well say it's in no order at all. But it is in _some_ order; keys(), values(), and each() all use the same, repeatable, order (at least, until you add new items to the hash). If you need any particular order, of course, that's easy to get. You can either sort items directly into the order you want, or you could use a module that keeps a hash in order for you.
