Ok, lets see if I understand you correctly.

So the size of your array size = 0. and iBalance is != 0 a couple of lines down.

I'm really confused about your output. The array size you declared above is =
0, therefore the is no space for anything. But still you manage to print out
things from iLabelNode[0] and iLabelNode[1], which don't exist because the size
of iLabelNode = 0. I think iBalance should be initialized to 1 (int iBalance =
1) so there is 1 space in that array. This looks like a mistake I make a lot.
I get initialization of arrays and referencing arrays confused. if I type:
int array_of_int[1] ;
It means that I have only space for one thing:
array_of_int[0] = something;
If I initialize the array like this:
int array_of_int[2] ;
That means I have to spots to put information:
array_of_int[0] = something, array_of_int[1] = something + 1 ;
I hope it helps, but if you could send in some more code (preferably so we can
duplicate your error) we might be able to understand your problem a little
better.
