Destruction is often viewed as just another operation, albeit with Specific semantics that make nonvirtual phone calls unsafe or Incorrect. For a foundation class destructor, thus, the choice is concerning enabling it for being termed by means of a pointer to Base pretty much or by no means; “nonvirtually” will not be a possibility.

Some regulations aim to enhance numerous types of basic safety while others intention to lessen the probability of mishaps, numerous do the two.
Corollary: When producing a foundation course, generally create a destructor explicitly, as the implicitly created one is general public and nonvirtual. You are able to often =default the implementation In case the default entire body is fine and you also’re just composing the operate to provide it the appropriate index visibility and virtuality.
