std::ctype <char> :: ~ctype

Destructs a std:: ctype < char > facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std:: ctype < char > , like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std:: ctype < char > and implements a public destructor.

If, when this instance of std:: ctype < char > was constructed, a custom classification table was provided and the second argument to the constructor (the boolean del ) was true , then this destructor executes delete [ ] table ( ) .
