:::::Associative array is not an array, just like butterfly is not a fly. Of course it is possible that the data of an associative array is internally stored in an array. After all, a real associative array can not exist in normal computer memory, you would need special hardware. Array is quite a clear concept, as specified in Wikipedia. For example, it is always indexed with integer. (Note: enumeration type ''is'' integer).
:::::I think this page should be an encyclopedia article. Then, some tasks could be created for performing some specific array operations. There is already at least [[Array Initialization]] and [[Creating an Array]]. Maybe there could be a category for grouping these. --[[User:PauliKL|PauliKL]] 16:25, 3 April 2009 (UTC)
:::::: <nowiki>[</nowiki>Please do not feed my interest in word-playing or filology by writing such a nonsense thing like "associative array" ≠ "array" deduced by "butterfly" ≠ "fly"; it's a completely different thing! I couldn't help answering this with at least this ''bit'' :D<nowiki>]</nowiki> --[[User:ShinTakezou|ShinTakezou]] 22:42, 3 April 2009 (UTC)
::::::Enumeration is not an integer, except than in C, which, honestly, does not have enumerations. Let us not confuse ''named integer constants'' with enumeration type. Integer is a datatype that provides a certain set of operations ([http://en.wikipedia.org/wiki/Peano_arithmetic Peano arithmetic]). Enumeration is a set of values without such operations except for comparison and copy.
::::::The key logical difference between associative and "plain" arrays is that the index of former is not necessarily dense, which does not allow iteration. The commonality is that both are maps of index to element. --[[User:Dmitry-kazakov|Dmitry-kazakov]] 08:27, 4 April 2009 (UTC)
