A destructor of a class A is trivial if all the following are true: It is implicitly defined. All the direct base classes of A have trivial destructors . The classes of all the nonstatic data members of A have trivial destructors.

A class has a non-trivial destructor if it either has an explicitly defined destructor, or if it has a member object or a base class that has a non-trivial destructor .19 Kas 2011
Read moreWhat are the types of destructors?
Destructors cannot be declared const , volatile , const volatile or static . A destructor can be declared virtual or pure virtual . If no user-defined destructor exists for a class and one is needed, the compiler implicitly declares a destructor.
Read moreHow many types of destructor are there?
There has to be only one Destructor in a class . A Destructor has no return type and no parameters. If we do specify a destructor in class then, the compiler creates a default destructor.

Trivial destructor The destructor for class T is trivial if all of the following is true: The destructor is not user-provided (meaning, it is either implicitly declared, or explicitly defined as defaulted on its first declaration) The destructor is not virtual (that is, the base class destructor is not virtual)

A destructor is a member function that is invoked automatically when the object goes out of scope or is explicitly destroyed by a call to delete . A destructor has the same name as the class, preceded by a tilde ( ~ ).
