C++ Simulator of a Nondeterministic Turing Machine has been added at : * http://alexvn.freeservers.com/s1/turing.html * http://sourceforge.net/projects/turing-machine/ Currently those sites contain C++ Simulators for both Deterministic and Nondeterministic Turing Machines. The Simulators contain examples of Turing Machines as well.

I've made no secret of the fact that I really dislike the C preprocessor in C++. No aspect of the language has caused me more trouble. No aspect of the language has cause more code I've read to be difficult to understand. I've described it as GOTO's on steroids, and that's what it is!.
