Virtual Functions in C++ — vtables, Pure Virtual Functions, and Abstract Classes
One virtual function grew a class from 4 bytes to 16. Three kept it at 16. What vtables cost, measured, plus the destructor rule nobody mentions.

C++ Programming: Complete Beginner’s Guide to Modern C++ (2026)
C++ powers the software where speed matters most, from game engines to trading systems. This guide takes you from your first program to modern C++, one concept at a time.
Easy ways to cope with C/C++ Assignment
C++ is one of the fastest, most reputable and effective languages in the programming world. In this article, you will learn about the top mistakes people make and how to eliminate them so that your C/C++ homework is bold and clear.
Difference Between [] and {}: Arrays vs. Objects in JavaScript
In JavaScript, we use braces {} for creating an empty object and brackets [] for creating an empty array. I find the Developer console in Mozilla Firefox or Google Chrome more convenient to print out any object and study the details.
Multiparadigm Programming in Standard C++
A multi-paradigm programming language allows programmers to choose a specific single approach or mix parts of different programming paradigms. The power of C++ is such that it can be used to implement any paradigm. It supports procedural and class based object oriented programming as well as there is functional programming support in the modern standard library versions. The free-form nature of C++ can also be used to write obfuscated C++ which in one context can be seen as artful control over the language.
Polymorphism in C++
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).
50 C++ Interview Questions
I have compiled a list of repeatedly asking C++ interview questions here. Some of them are very important C++ questions
An Introduction to C++
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.

This is a simple C++ Program to demonstrate Function Name Overloading. An example of function name overloading within a C++
Advanced C++ Inheritance Techniques for Effective Object-Oriented Programming
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.
Inheritance in C++
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.
Objects: Object Oriented Programming
The basic idea behind the Object Oriented Programming is that it deals with the objects. In real life everything is an object and every object has properties and functionality.
