Question

Both arguments are guaranteed to be integers.

How do I write myMax such that:

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

I want this to be evaluated at compile time, not run time. (Need to then use this with sizeof for a typelist to allocate space for a variant.)

Thanks!

Answer 1

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

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