Hi Everyone,

I'm new here and a fellow ChucK addict.

How do I get the size of a multidimensional array? I'm passing a multidimensional array to a function in a new class and I want that function to determine the array size.

I'm writing a very simple non-uniform random number generator that will use multi-dimensional array containing target numbers and weights (propability of selection).

For example, here's skeleton code.

Code:
// Non-Uniform Random Generator
class Nurg
{
    int weightMap[][];

    public void SetMap ( int newMap[][])
    {
        newMap @=> weightMap;
    }
}


[ [ 0,1 ], [1,1], [2,3], [3,3], [4,1], [5,1], [6,1] ] @=> int myWeightMap[][];

Nurg myNurg;
myNurg.SetMap (myWeightMap);


So how can I know the size of the newMap array inside my SetMap function?

Sorry if this is a silly question. I'm just starting to learn..

Thanks Smile

Well,
Code:

newMap.cap()


Will give you the size of the first dimension. The length of the others need not be the same but


Code:

newMap[0].cap()


Will give you the size of the first, which will be the size of the others as well if you never change their length.

Does that help?

You were lucky, I'm off to bed now so the next answer from me may take 8 hours. Clearly we need ChucKists in more time-zones for strongly timed answers! :¬)
