Friend Function in C++ Welcome to C++ Programming. In this article, we will talk about friend Function and friend Class trying to understand what do they mean and why are they useful in C++ design process. These will be the module outline we will take examples of Matrix Vector Multiplication and Linked List, and finally will end with somenotes. As you know as usual the outline will be available on the left of your slide So, let us first introduce the basic notion of friend function. On the left you have the view of ordinary function. So the situation is like this, that I have a class myclass which as some private data, it has a constructor, and it has; I am sorry if just ignore this line. I have this function written outside of this class which is trying to do something with the class. What is it doing? It takes an object of the class by reference parameter call by reference, and then it tries to print the data element component of that objective. Now, what do we know, this is pr...

Constructor C++

                        Constructor is used to initailize the data members automatically.A constructor is a member function of class.It execute when object of that class created.It means that when object of class created the constructor executes automatically.By default there is constructor even if you dont write it.


 Constructor Syntax 

                         The syntax of constructor is like same name of class e.g if the name of class is A so the constuctor will start with A(){ here is the body }.


Copy Constructor C++

                   Just read about copy constructor and assignment operator they can create a big problem in real world projects they cannot be used but for you should have some knowledge about it.

1.Programming language in C++ C++ is one among the world's hottest programming languages . C++ are often found in today's operating systems , Graphical User Interfaces , and embedded systems . C++ is an object-oriented programing language which provides a transparent structure to programs and allows code to be reused, lowering development costs.The general purpose programming language of c++ is to use the class shape which was not in c language.Which is created by bjarne stroustrup as an extension of c language. 2.Object Oriented Programming Object Oriented programming in c++ as the name suggests, it uses objects in programming. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism, etc in programming. The main aim of OOP ( Object-oriented programming) is to bind together the info and therefore the functions that operate them in order that no other part of the code can access this data except that function...
