Copy constructor example

• How are copy constructors defined ?

  
      // point.h
      class Point
      {
          public:
              Point( Point& other ); // copy constructor
          private:
              int m_x;
              int m_y;
      };
  
      // point.cpp
      Point::Point( Point& other )
      {
          m_x = other.m_x;
          m_y = other.m_y;
      }
