C++ template metaprogramming

Template metaprogram sample

template<int N> struct Factorial
	{
	enum
		{
		value = N * Factorial<N-1></n-1>::value
		};
	};

templatestruct Factorial<1>
	{
	enum { value = 1 };
	};

int	i = Factorial<10>::value;

This simple template can be used to calculate factorial during compilation.
