Why is C++ numeric_limits::max() == 0?

Question

Here\'s a bit of code that might seem like it would work:

#include 
#include 

enum test { A = 1 };

int main()
{
    int max =          


        

Answer 1

For non-specialized versions of the template, max returns T(). You have not written a numeric_limits specialization for your test type, so you get the default implementation.
