Re: Odd g++ results

[Jeffrey Holle]

This is likely because the order of execution of parameters in C/C++ 
shouldn't be relied on.  The "operator <<" is just a function after all...

If one codes like:

int main()
{
  int a = count();
  int b = count();
  int c = count();

  cout << "first " << a
       << " second " << b
       << " third " << c
       << " \n";

}

The output is as you expected.
