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.
Polymorphism
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.
Polymorphism in Object-Oriented Programming: Overloading, Overriding and Duck Typing in C++, Java and Python
How one call runs different code for different objects: overloading, overriding, virtual functions, generics and duck typing in C++, Java and Python.
Object-Oriented Programming in C++: Classes, Encapsulation, Inheritance and Polymorphism
How C++ does OOP differently from Java and Python, with one program that uses all four pillars and the slicing and override mistakes that still compile.

Queue Implementation with Inheritance and Polymorphism
Following is the source code of simple queue implementation with the help of Inheritance and Polymorphism i.e. Late Binding.
Object-Oriented Programming: Concepts, Pillars and Techniques in C++, Java and Python
How OOP differs from procedural code, what its four pillars mean, and the techniques that keep object-oriented code easy to change, in three languages.
