Incidentally, the Draft is broken as regards

  bool b;
  cin >> boolalpha >> b;

It's quite embarrassing, but the code above has indeterminate results 
because the Draft says if b (going in) is true, >> will try to match
"true", or if false, then "false", and report an error otherwise.  
In other words, you have to know what you're about to read before you
read it.  There will be a defect report about this.
