Decoding the Virtual Functions of C++ Programming Language

: : Probably the least understood and often misunderstood part of learning C++ programming the virtualization of a function in a C++ class. The mnajor reason behind the confusion of cplusplus or c++ virtual functions is that as part of implementing the virtual mechanism, the C++ compiler change the code written by the programmers and the programmers have no obvious mehcnism of visualizing the same.

This mechanism is sometimes also called as run time polymorphims or dynamic binding. So to properly understand this concept of C++ virtual functions or run time polymorphism or dynamic binding we can actually implement the mechanism on our own without using the C++ Compiler.

So in this video, I've talked about the theoritical concepts of virtual function and validated the same using the same for the implementation of my own virtual mechanism.

I do hoppe and believe that this video was helpful to all of you.. Thanks for watching
