8. Rectangle name setter and getter functions

• Besides naming the rectangle when we create it, we also want to copy rectangles and rename them any way we want.

• Thus, new member functions provide read/write access to the object's name:

  
  struct Rectangle {
      int width;  // member variable
      int height; // member variable
      char const* ptr_name;
  
      //...
  
      void set_name( char const* ptr_name_ )
      {
          ptr_name = ptr_name_;
      }
  
      char const* get_name() const
      {
          return ptr_name;
      }
  
      //...
  };//struct Rectangle
  
  

• Since get_name() makes no changes in the object's state, it is declared const.
