Using numeric_limits::max() in constant expressions

Question

I would like to define inside a class a constant which value is the maximum possible int. Something like this:

class A
{
    ...
    static const int ERROR_V         


        

Answer 1

You want:

#include 

struct A {
static const int ERROR_VALUE;
}; 

const int A::ERROR_VALUE = std::numeric_limits::max();

Put the class/struct in a header and the definition in a .cpp file.
