What is the difference between a constructor and a destructor?
A Destructor is a method for a class that gets called automatically whenever an object of the class is deleted. Its name is always the class name preceded by a ~, it takes no arguments, and there is no return value, not even void. Point(); ~Point(); A Constructor is defined like any other method, but it never has a return value (not even void).
What is a class destructor?
A class may define one or more constructor. It is up to us to decide which constructor to call during object creation by passing an appropriate parameter list to the constructor. We may set the default value for the constructor parameter. class destructor is a class method having the same name as the class name and is prefixed with tilde (~) sign.
Why can't I use references and pointers on constructors and destructors?
References and pointers cannot be used on constructors and destructors because their addresses cannot be taken. Constructors cannot be declared with the keyword virtual. Constructors and destructors cannot be declared static, const, or volatile. Unions cannot contain class objects that have constructors or destructors.
