String to enum in C++

Question

Is there a way to associate a string from a text file with an enum value?

The problem is: I have a few enum values stored as string in a text file which I read on

Answer 1

You can calculate the hash of the string and then use this:

template 
E map_hash(H const key, std::initializer_list> const il)
{
  auto const i(
    std::find_if(il.begin(),
      il.end(),
      [key](auto& p)
      {
        return p.first == key;
      }
    )
  );

  assert(i != il.end());

  return i->second;
}
