What is a destructor example?

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

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.

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)
