Don't let the llama to discourage you. You do not need to pay to learn this. If you are a C++ beginner there's no way that you can understand how to do that anyways. If you are a beginner try to get better(at least intermediate if not advanced). Then you can use GMP( https://gmplib.org/ ) to do what you're trying to do. Noone will do your "homework" for you for free and if they were to do it, it is not easy to understand someone else's code(especially on a subject that requires libraries and such)! Try too do something and say what did you tried!

You might want to take a look at:
http://stackoverflow.com/questions/2568446/thebestcrossplatformportablearbitraryprecisionmathlibrary http://mathforum.org/library/drmath/view/63866.html http://en.wikipedia.org/wiki/Arbitraryprecision_arithmetic To have an idea about using arbitrarily big numbers like 1000! (factorial of 1000).But keep in mind that using bignum arithmetic is much slower than fixedprecision arithmetic that you use with smaller numbers.
