How to Ensure a Class is not Copyable or Movable

by Sandor Dargo

From the article:

If we follow the classification proposed by Sebastian Theophil, we can talk about 4 different class types:

ItΓÇÖs up to us to ensure that a class we create implements the right special member functions (SMFs from now on). And the Hinnant table is here to guide us.
