16. Access control declarations

• Use as many access specifiers as you want, in any order.

• Each one is in effect until the next one, or the end of the declaration.

• Specifiers go only in class declarations, nowhere else.

  
      // point.h
      class Point
      {
      private:
          int m_x;
          int m_y;
          void reset_coordinates();
      public:
          double distance_to_origin();
      };
