C++ Tutorial: Inheritance, Polymorphism, Virtual Functions, Abstract Base Class

In this video, I write a short program that utilizes the object-oriented programming principles of polymorphism and inheritance.

Inheritance: ~1:30
base class/derived class constructors ~9:00
virtual functions/dynamic binding/abstract base class: ~20:00
polymorphism: ~28:20

Great tutorial :) Thanks. So much better at explaining everything in 35 min than an hour and half class that i'm taking. Much appreciated!

[locallion]

Very clear. Not many explain the motivation behind using polymorphism but yours was very good. Thank you.

[tamburaimashonganyika]

i was struggling with virtual function now you simplified it thanks a lot.

Awesome video! Extremely clear and concise. You wrote everything out even though it would have taken a bit more time, but it actually helps to see every little piece drawn out.

Excellent refresher with some great, straightforward explanations. Thank you!

Thanks a lot, very helpful :)
and btw, because of some other comments that claim this to be the most useful video among others they checked, i consider myself lucky that i found this video first :D on my search

Cleared it all up for me! Hope to see you in my upper divisions next spring!

[seanmurtagh]

Great tutorial man, thanks. Also taught me the use of const in accessor functions which I never knew about.

[splendidzr]

So why dont Triangle class have a word "virtual" ahead of getArea() function?

Great video, really helped me wrap my head around all this sort of stuff. I actually liked how you was slipping up a little since it meant I was identifying where you were making typos and mistakes before you corrected them hahaha. Liked and subscribed (Y)

[sukald]

Excellent video! learned a lot of things.

[TheRobiel]

Thanks a lot Professor Hank. This was very helpful.

[abdelouery]

Thanks Alot, This is the best tutorial about OOP in C++.

One more thing why did you used the const keyword in class functions, i know it's for constants, but why classes?

[cfloresana]

Thank you for the video. It helped further understand the material.

Very good explanation of the example. Although at 8:10, the public access specifier makes the protected members of the derived class protected not private. Also, you should free the shapes array. I don't want to sound like a know it all. I understand it takes a lot of effort in making these videos. Anyways thank you for making nice videos.

[husseinalaa]

Thank you, this was very clear explanation

Two unmentioned pluses: There are actual human pauses between sentences.  Not the usual staccato technique.  And, the cadence is more normally paced.  Seems like lots of  others race along like they have somewhere else they need to be in the next five minutes.  Thanks!
