A1:	Here's a prototype for the class definition file and a function definition for the methods file: // prototype Stonewt operator*(double mult); // definition -- let constructor do the work Stonewt Stonewt::operator*(double mult) { return Stonewt(mult * pounds); }
2:	What are the differences between a friend function and a member function?
