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();
};
