Destructors are functions with the same name as the class but with a tilde before them.
The declaration of destructors is governed by several rules:
It is possible to declare it as virtual. You can destroy objects without knowing their type by utilizing virtual destructors; the virtual function mechanism calls the correct destructor for the object. For abstract classes, destructors can also be defined as pure virtual functions.
Destructors are a type of destructor that is used to destroy anything.
When one of the following events occurs, destructors are invoked:
When an item is removed from the scope or deleted, the following series of actions occur:
