Passing a 2D array to a C++ function
...the result as int*, to which it would add j and dereference that location, reading an int. So, no, it needn't know any dimension for this. But, that's the whole point! The compiler takes the programmer's word in faith and if the programmer was incorrect, undefined behaviour ensues. This is the reaso...

Thread.currentThread().getContextClassLoader().getResource(name)
