How to write a C ++ template that gives a maximum of two arguments?

Question

Both arguments are guaranteed to be integers.

How to write myMax so that:

myMax<1, 2>; // 2 myMax<3, 2>; // 3 ? 

I want this to be evaluated at compile time, and not at runtime. (You must then use this with sizeof for the type list to make room for the variant.)

Thanks!

Answer 1

 template <int x, int y> struct myMax { static const int value = (x > y) ? x : y; }; 

If you are going to use it only with sizes, you can use std::size_t instead of int .
