Rule #1: You must have an declarative keyword like Dim/Global/Local before the declaration.

Not if you are returning it from a fuction.

$aArray = StringSplit("123", "");

wouldnt an empty array be

Local $aEmptyArray[0]

as your current example is a 1D array with a single element, and that single element is an empty string.

 

#include<array.au3>

Local $aEmptyArray[1]
_ArrayDisplay($aEmptyArray) ;array with 1 entry
msgbox(0, '' , $aEmptyArray[0]) ;empty string

Local $aEmptyArray[0]
_ArrayDisplay($aEmptyArray) ;array with 0 entries
msgbox(0, '' , $aEmptyArray[0]) ;nothing because the array is empty

@TheDcoder , This could be useful when you have .NET in your PC. 

Local $aAlist = ObjCreate("System.Collections.ArrayList")

$aAlist.Add ("Test")
$aAlist.Add("Sample")

@kcvinu Oh :o, It seems that you created an object which acts as an array... As I am like fresh out of the school in objects, I can't use your example efficiently enough :P, Also it would confuse any newbies reading :wacko:... Anyways lets stick to the native AutoIt way :)

 

P.S _ArrayAdd would be the same as the "Add" method :P

Basically i don't like to use ReDim. So this is my first choice.  _ArrayAdd uses ReDim. But this is not.

@TheDcoder here is the result. For a small array with 10 element, _ArrayAdd is the faster method.  This is the result

ArrayAdd Time = 0.46618648011839 ms
ArrayList Time = 2.82040846777807 ms

But for a large array with 2225 elements, ArrayList is faster.This is the result

ArrayAdd Time = 1449.32797699147 ms
ArrayList Time = 48.0397075617342 ms

Nice! :D, Why won't you try to make an alternative to ReDim using the "Add" method? Perhaps a snippet would do the magic! :sorcerer:

ArrayList is a horrible choice, because it's not a generic collection and therefore you have a lot of boxing and unboxing to do during execution. Anyhow, you are aware that under the hood, List and ArrayList are basically arrays that hold the length and current index position? They essentially use Array.Copy() when a new item is added which is outside the current length of the array. If people didn't realise, that's all ReDim is, a syntactic sugary array copying method!

@guinness , i didn't know that the under the hood secrets. But why did the speed varies when working with the large arrays ?

@kcvinu AutoIt is slower than NET, I think NET has a constant work load with arrays, where as AutoIt has a constant work load with elements of an array...

So more elements = more slower in AutoIt

Well then you pretty much hate every popular language out there.

@TheDcoder, maybe you could answer this question...why does the index value start from zero and not one?

Yes. And now i am fighting with myself to learn javascript. When i look into a piece of code, my mind is tempting to close the page and go to any other off side rule languages. :)

Rule #1: You must have an declarative keyword like Dim/Global/Local before the declaration (Note that a function can still return an array to an undeclared variable, therefore creating an array without a declarative keyword)

The Variable is declared as soon as you type it in.

Here is a suggestion

"You must have a declarative keyword like Dim/Global/Local before the declaration unless the array is assigned a value from a functions return."
