C++ Will Never Die
Wow. I can't believe this compiles in C++. The 'msg' that I am passing to the constructor is the same 'msg' that I am trying to create. Needless to say, that call to getNeighbor() puts a bunch of garbage in the object. It took me a very long time to track down the source of this garbage from some seg faults located in another thread. Boo.

I've been trying to think of a circumstance when it might be helpful to be able to reference an object on the same line as it's instantiation, but I really just can't. I can't wait until I have the opportunity to get out of my c++ hole and learn a language that's actually fun to program in. btw you missed a sweet dance party at girl house the night you left. I got drunk, and broke the lamp above the pool table with my head while dancing. We all missed you dearly.

I've got a C Code, not written by me, sent by a friend of mine. Do check it out. I am sure, the output shall amaze you. It uses Recursion with Pointers, just see if you could follow its trace?
