Re: ifstream "fail()" vs. "eof()" question.

Say I have an ifstream object, like so:

#include <iostream>
#include <fstream>
int main(int, char* Sam[])
{
  std::ifstream Bob;
  Bob.open(Sam[1]);
  std::string buffer;
  while (42)
  {
     getline(Bob, buffer);
     if (Bob.fail()) std::cerr << "Stream failed!" << std::endl;
     if (Bob.eof())
     {
        std::cout << "eof" << std::endl;
        break;
     }
     std::cout << buffer << std::endl;
  }
  return 0;
}

On my compiler, fail() will come up true whenever eof
occurs. And yet, I've read that fail() is supposed to
to be true only when a non-eof stream failure occurs:

So, is my compiler messing up? Or is the info on that
web site wrong? They can't both be right.
