A constructor is a special method that is created when the object is created or defined. This particular method holds the same name as that of the object and it initializes the instance of the object whenever that object is created. The constructor also usually holds the initialization of the different declared member variables of its object.
As opposed to a constructor, a destructor is called when a program has finished using an instance of an object.
As we begin the study of C++ and object oriented programming, a few comments are in order to help you get started. Since the field of object oriented programming is probably new to you, you will find that there is a significant amount of new terminology for you to grasp. This is true of any new endeavor and you should be warned not to be intimidated by all of the new concepts.
The principle of inheritance is available with several modern programming languages and is handled slightly differently with each. C++ allows you to inherit all or part of the members and methods of a class, modify some, and add new ones not available in the parent class. You have complete flexibility, and as usual, the method used with C++ has been selected to result in the most efficient code execution.
Encapsulation is a fundamental concept in Object Oriented Programming (OOP) that involves bundling data (attributes) and methods (functions) into a single unit known as a class. This encapsulated unit acts as a self-contained module which enhances code organization and promotes a more intuitive and manageable structure for programmers.
Welcome to the another C++ article where we will uncover the language’s flexibility and power through various data types. In this article, we’ll explore the compounded types such as Enumerated Types, Simple Structures, Very Simple Classes, the intriguing concept of the union and Type Conversions in C++. So, buckle up, aspiring programmers, as we embark on a journey to demystify these essential building blocks of C++.
Everyone knows that memory management is a difficult and dangerous chore in C++. This series of three articles will show you that the conventional wisdom is not true. When approached correctly, C++’s seemingly archaic memory-management scheme actually provides an opportunity to create spectacular programs – programs that would not be possible with more modern languages that handle memory automatically.
In Object Oriented Programming Inheritance is the process by which objects of one class acquire the properties and functionality of objects of another class. In the last tutorial on inheritance in C++ we developed a model using modes of transportation to illustrate the concept of inheritance. In this article we will use that model to illustrate some of the finer points of inheritance and what it can be used for.

The goal of these columns is to explore object-orientation through practical object-oriented programming. This time, we look at C++, but in the future we will explore other areas of object-orientation. Learning an object-oriented language-a whole new way of programming-will pave the way for many exciting topics down the road.

Simply speaking, polymorphism is the ability of something to be displayed in multiple forms. Let’s take a real life scenario; a person at the same time can perform several duties as per demand, in the particular scenario. Such as, a man at a same time can serve as a father, as a husband, as a son, and as an employee. So, single person possess different behaviors in respective situations. This is the real life example of polymorphism. Polymorphism is one of the important features of Object Oriented Programming (OOP).
