This forum is dedicated to the Computer Algebra System (CAS) Mathematica. Since your request is about programming in C++ and Stephen Wolfram's New Kind of Science (NKS), I would strongly encourage you to post your question in one of the NKS forums available at http://forum.wolframscience.com/ or/and on one of the newsgroups dedicated to C++ programming: you will.
