C Programming. Control System. The name constructor was initially used for an object to initialize. A destructor is initially used for a person who helps to delete an object. Both the constructor and destructor are two terms that arise from the same ring, but two have differences.

The difference between constructor and destructor is that a constructor is used by a person who helps to allocate an object in a specific term for a specific period, and on the other hand, a destructor is used by a person which helps him or her to dislocate an object in a specific term for a particular period.

There are many functions present and out of those is the function of the constructor, which helps in allocating memory of an object to help it get Initialized. It is very easy to indicate which is a constructor as they are well defined to their name with the same classes.

It is called while object of the class is freed or deleted. It is always called in the reverse order of the constructor. Skip to content. Change Language. Related Articles. Table of Contents.

A destructor, on the other hand, is called when instance of a class is deleted from the memory which in turns de-initializes objects that were created using constructors to free up memory for new objects.

A constructor is nothing but a method that has no Return Type, not even void, whereas destructors are exactly the opposite of constructors. Both constructors and destructors are called automatically after creation and deletion.

However, unlike constructors, destructors cannot be overloaded. Overloading is an object-oriented programming concept that allows you to define two or more functions with the same name so that you can call them with different argument lists. In object-oriented programming, constructors often accept arguments that they use to set required member variables, whereas destructors do not accept any arguments.

The purpose of destructors is to de-initialize objects that were created using constructors in order to free up memory space to accommodate new objects. Difference Between Constructor and Destructor.
