Question:What is Method Overloading? 

Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. In the last tutorial we discussed constructor overloading that allows a class to have more than one constructors having different argument lists.

Question:Define Operator Overloading. 

In programming, operator overloading—less commonly known as operator ad hoc polymorphism—is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by the language, the programmer, or both.

Question:Define Object Cloning. 

Object cloning method in the programming language for object duplication. In Object Oriented Programming, objects are manipulated through reference variables, and there is no operator for copying an object—the assignment operator duplicates the reference, not the object. The cloning method provides this missing functionality.

Question:Define Abstract Class.
