pow (power) template implementation from wiki
c++, enums, templates
Solution
There could be a difference if you ever try to take an address of an `static const int`. In that case, the compiler will generate storage for the `static const int`. You can't take the address of an `enum` and the compiler will never generate storage for it.

Possible Duplicate: Template Metaprogramming - Difference Between Using Enum Hack and Static Const please explain what for is `enum` used in following implementation of power template. ``` template<int B, int N> struct Pow { // recursive call and recombination. enum{ value = B*Pow<B, N-1>::value }; }; template< int B > struct Pow<B, 0> { // ''N == 0'' condition of termination. enum{ value = 1 }; }; int quartic_of_three = Pow<3, 4>::value; ``` I found it on wikipedia. Is there a difference between `int` and `enum` in this case?
