Destructors are members of functions in a class that delete an object when an object of the class goes out of scope. Destructors have the same name as the class preceded by a tilde (~) sign. Also, destructors follow a down-to-top approach, unlike constructors which follow a top-to-down.
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 or delete[] . A destructor has the same name as the class and is preceded by a tilde ( ~ ). For example, the destructor for class String is declared: ~String() .
