// Exercise 15.1:
// What is a virtual member?
//  A virtual member in a base class expects its derived class define its own version.
//  In particular base classes ordinarily should define a virtual destructor, even if
//  it does no work.
//
// Exercise 15.2:
// How does the protected access specifier differ from private?
//      private members     :   base class itself and friend can access
//      protected members   :   base class itself, friend and derived classes can access
// Exercise 15.3:
// Define your own versions of the Quote class and the print_total function.
//
//

#include <string>
