In a class, there can be multiple constructors. Here, itвЂ™s name is also same as the class name preceded by tiled (~) operator. The constructorвЂ™s name is same as the class name. While it is used to deallocate the memory of an object of a class. Constructor is used to allocate the memory to an instance or object. It is called while object of the class is freed or deleted. A constructor is called when an instance or object of a class is created. Constructor can either accept an arguments or not. It is declared as Classname( arguments if any ). Whereas destructor is used to destroy the instances. Constructor helps to initialize the object of a class. Note: If we do not specify any access modifiers for the members inside the class then by default the access modifier for the members will be Private.Д®xample/Implementation of Constructor and Destructor: class ZДifference between Constructor and Destructor in C++ : S.NO Constructor Destructor 1. if a class is inherited by another class and both the classes have a destructor then the destructor of the child class is called first, followed by the destructor of the parent or base class. It is always called in the reverse order of the constructor. In a class, there is always a single destructor without any parameters so it canвЂ™t be overloaded. It helps to deallocate the memory of an object. Like constructor, deconstructor is also a member function of a class that has the same name as the class name preceded by a tilde(~) operator. There is a concept of copy constructor which is used to initialize a object from another object. It can be overloaded but it can not be inherited or virtual. It can be defined manually with arguments or without arguments. It is called whenever an instance of the class is created. It is used to allocate the memory to an object of the class. It can either accept the arguments or not.
