Can't incremen int inside funciton call -- bug?

[Ary Manzana]

Hi.

Shouldn't that be ++treeLevel?

In general var++ is an expression that returns var and leaves var with 
the value var + 1. ++var is an expression that returns var + 1 and 
leaves var with var + 1.

int x = 1;
int y = x++; // leaves y = 1, x = 2

int x = 1;
int y = ++x; // leaves y = 2, x = 2

Further, your two codes are differentes. In the first one you increment 
treeLevel in each foreach iteration, while on the second you increment 
it once before the foreach loop.

Best regards,
Ary
