## Unanswered: Acessing Dynamic Array elements by number

Hi all...

I know you can access normal array elements using the myarray[1] type of syntax, but is it possible to access the elements of a dynamic array using the same type of syntax?

I.e instead of dynArr["name"] use dynArr[2] ?

Thanks foir the help! Thought I'd accessed them this way before but now it doesn't seem to work!

Cheers!

## A little juggling

keys in dynamic arrays are always strings instead of integers but you can get around it with a little juggling:

Say you have a dynamic array "lottastuff" with 12 elements,

you need to add a fixed string array variable say "lskeys"

Now you load the elements from lottastuff into lskeys with

lottastuff.getkeys(lskeys).

At this point lskeys[1] = the first element in lottastuff
lskeys[2] = the second element in lottastuff etc.

Now to address an element in lottastuff directly using integers you simply use

lottastuff[lskeys[3]] which would be the value of the third element in lottastuff[].

Thanks very much, didn't think of it that way...

I got round what I was doing, albeit in a crappy way.. But it wasn't a very nice project I was working on and was glad to finish it heh

Thanks again!

The order in which keys appear in a DynArray (e.g. with forEach) may change at any time. There is no concept of "ordering" of a dynamic array.

Likewise, in an ordinary Array, there is no concept of keys.

Actually the "order" of the keys don't change. There is no concept of "order." But a virtual order can be established using a standard array as a proxy.

The solution to the problem is not found in answering the question asked, but in understanding it.
