Hi,

Is there a way to assign the starting array address to another variable? If it can, how can I do that? I have a lot of arrays and I am picking one that is to be used in certain situations. I want to avoid repeating line of codes or using select every time.

In cpp you can assign something like this:

int *arrayptr;
int sample[10];
int sampleAgain[5];

arrayptr = sample; 'where sample holds the address of index-0

Monkey doesn't have pointers, so no.

I see... but can it at least be referenced?

What be referenced? The memory address of the array? If that's what you're asking about, then no.

If on the other hand you're asking: If 'a' is an array datatype and 'b' is an initiated array when 'a' assigns 'b', 'a' becomes a reference to 'b'. Then the answer is yes.

Function Main:Int()
    Local a:Int[]
    Local b:Int[] = [0]
    
    a = b
    a[0] = 1
    
    Print b[0]
End

That's a good alternative. Thanks Goodlookingguy.

P.S. Your name makes me look like I'm flirting. -_-"

You can pass arrays around, but you can't re-assign them (without losing the reference).


Local a:Int[] = [ 3, 4, 5 ]
DoSomething( a )

Function DoSomething( arr:Int[] )

' This works to change a to [ 3, 10, 5 ]
arr[ 1 ] = 10


' This has no effect on a
arr = [ 3, 20, 5 ]

End

The second line in DoSomething doesn't affect a because arr is set to point to a completely new array (which will be forgotten about when the function returns). The first line works because arr points to the original array a.
