Function Overloading In C++


                                  

C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.

Function Overloading is compile time polymorphism.

Function Overloading is the practice of declaring the same function with different signature.

same function name used with different number of parameters and parameters of different type.

Overloading of Function with different data types is not allowed.

A Function is overloaded when same name is given to the different functions.

Two functions with same name is must differ in at least one of the following.
                          
  1.  The data type of parameters
  2.  The order of appearance
  3.  Number of parameters

C++ Inheritance  C++ inheritance : In The Language C++, inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. Different way you can reuse, extend or modify the attributes and behaviors which are defined in other class. What Is Inheritance In C++? In the language C++, the class which inherits the members of another class is called derived class and the class whose members are inherited is called base class. In this C++ The derived class is the specialized class for the base class. Advantage of C++ Inheritance A Code reusability : Now you can reuse the members of your parent class. That's Why there is no need to define the member again. So less code is required in the class. Types Of Inheritance There are five types of inheritance: Single inheritance Multiple inheritance Hierarchical inheritance Multilevel inheritance Hybrid inheritance Types Of Inheritance?

Basic Concepts Of OOPC !!                                 OOPC is a object oriented programming which is contain many concept of class and objects. There are many concept like Inheritances, Polymorphism, Abstraction, Encapsulation etc ...  List Of Concepts :   Class Objects Inheritance Polymorphism Abstraction Encapsulation Message passing Class Class is a blueprint for any functional entity. It defines attributes and methods. a class is a implementation of abstract data type. a class is template that specifies the attributes and behaviour of objects.
