Cpp - c++ Destructors

Destructors are usually used to deallocate memory and do other cleanup
for a class object and its class members when the object is destroyed.
A destructor is called for a class object when that object passes out of scope or
is explicitly deleted.

A destructor is a member function with the same name as its class
prefixed by a ~ (tilde). For example:

class X {
public:
  // Constructor for class X
  X();
  // Destructor for class X
  ~X();
};
