What are the use of destructor function in class? What are its characteristics? Can a destructor accept arguments?

Destructor are used to destroy the objects that have been created by a constructor during the execution of C++ program. It has the same name as that of the class but is preceded by a tilde sign. 

For example, If A is a class then A() is known as its default constructor and ~A() as its destructor.

class A // Class declaration with class_name A

{

//declaration of data members.

public:

A() // declaration of class constructor 

{

statement 1...n;

}

~A() // declaration of class destructor 

{

statement 1...n;

}

};

Characteristics of destructor in C++ language:

1. A destructors is executed automatically by the compiler when program terminate.

2. A destructors releases memory space for future use after execution.

3. A destructors never accepts any argument or don't return anything.

4. It is not possible to take the address of a destructor.

5. A destructors can not be inherited in the derived classes.

6. A destructors cannot be overloaded.
