Confused between anonymous array and anonymous hash
 

my $ref = [{Shu => 21}, {Zee => 22}, {Haa => 11}];

a) hash containing anonymous hashes.
b) anonymous array of references to anonymous hashes.
c) array of arrays
d) anonymous hash of hash references.
e) multi-dimensional array

i am confused between (b) and (d).Which one is appropriate. Can anyone please explain me the difference.
Thank You..

"man perlreftut" should help you out.

First, check out http://www.perlmonks.org

Now on to your question: the variable $ref:

• Is a scalar (since "$foobar")
• Which contains a reference to an array (i.e. an "arrayref"),
• Each element of which is a reference to a hash (a "hashref").

In Perl, an array is a one-dimensional structure whose elements are accessed by a zero-based numeric index.

A hash is a one-dimensional structure whose elements are accessed by string key-values, such as (in this case) "Shu," "Haa," and "Zee."

A reference is simply "a thing," specifically a scalar thing, which "refers to" something else ... that is to say, "indirectly." A reference can refer to any sort of thing.

It is a good idea to prefix all programs with: use strict; use warnings;. Do this as a strict matter of routine, every time. Perl is otherwise "do what I (think you) mean." It can allow you to write stuff that isn't what you thought you were writing, unless you, in this way, ask for more stricture and warnings. Do so.

Moved: This thread is more suitable in <Programming> and has been moved accordingly to help your thread/question get the exposure it deserves.

In Perl there are no (strictly speaking) anonymous arrays and there are no anonymous hashes.

Instead anonymous array references and anonymous hash references do exist.

For simplicity/brevity the above references are called anonymous arrays and anonymous hashes. Unofficially :).

From your description and from all of the above description i came to a conclusion that it is an anonymous array of references to anonymous hashes..because i know for sure that anonymous array starts with a square bracket.

Thank you very much..it helped me alot..

You just think you know. But you don't. Here is a one-liner:

- the 'ref' function tells it's a reference of type ARRAY. From 'perldoc -f ref':
