  declare instance of custom class Demo
 ---------------------------------------
  #1 demo

  declare and use pointer to demo
 ---------------------------------
  #2 demo

  declare and use reference to demo
 -----------------------------------
  #3 demo

  declare and use pointer to Demo instance on heap

  #5 demo on heap
  destroying demo on heap

  you can declare and use reference to reference to a temporary
 ---------------------------------------------------------------
  #6 another Demo instance

  declare a unique_ptr to refer to heap allocation with automatic destruction
 -----------------------------------------------------------------------------
  #7 referenced by std::unique_ptr

  declare a shared_ptr sharing a reference counted heap allocation
 ------------------------------------------------------------------
  #8 demo referenced by std::shared_ptr sPtr1

  declare a shared_ptr sharing a reference counted heap allocation
 ------------------------------------------------------------------
  #9 demo referenced by std::shared_ptr sPtr2

  ---- end of main ----
  destroying demo referenced by std::shared_ptr sPtr2
  destroying referenced by std::unique_ptr
  destroying another Demo instance
