In this video we will learn about "Polymorphism in C++" programming language. It's a very important topic on oops.
POINS:
There are two types of Polymorphism
A. Compile Time Polymorphism / Static Binding / Early Binding
a. Function Overloading
b. Operator Overloading
B. Runtime Polymorphism / Dynamic Binding / Lazy Binding
a. Function Overriding (Using virtual functions)
For more details please watch full video and do let me know if there is any doubts in comment section.

Extremely thorough, covering all nuances. Thank you!

[@gagaantic9009]

Thanks for the videos! I’m a college student getting ready for interviews your videos really help me refresh!! :)

[@CppNuts]

You are most welcome Gaga Antic!!

[@yohanesSlamet]

Thx a lot For your work hard on The Video. I am Old enough for become beginner in C++, but because you are good teacher ... I have a lot of courage to work on it .....

[@CppNuts]

Glad to help..

[@tianmingguo8271]

great explanation!!!!! Thank you so much!!! one thing that makes me love your video so much is that your video always includes very sufficient information about one subject and inspires me to explore more about it.

[@CppNuts]

Thanks..

Could you please share the video links for below topics?
->Interface
->virtual table and virtual pointer

Sure...

I didn't know that problem with the hidden overloaded virtual function. I will definitely return to this video one more time and take notes.

What is the use of override in derived class its behaviour same with this word and vice versa

[@abhishekrai617]

Very Good Sir

[@CppNuts]

Thanks and welcome

[@RahulBhadana_cse]

please make video on overload new and delete operator

[@CppNuts]

Sure man!!
Coming in 2-3 days.

[@konstantinrebrov675]

Please publish some lectures on advanced exception handling: rethrowing exceptions, stack unwinding, exceptions and destructors, and some possible bugs that may happen.

[@CppNuts]

Yess dude, trying to push as fast as possible.
As this is my part-time sometimes it hard even to think about it. But will definitely push these topics, they are really interesting topics.

[@sugasinipalanisamy7892]

Could you please make video of vtable and vptr

[@frostypanda9317]

Thanks a lot.

[@CppNuts]

Thanks man.

[@xxxxx-l6g]

Hello Rupesh, thank you for the video!
I'd like to see from you some video on the topic where you will be discussing C++ books out there from the standpoint of your own experience and providing some details on what was beneficial for you from that book, what was not that good, etc..

[@CppNuts]

Noted.. thanks man..

[@sabbulingineni]

please share virtual table and vptr concept

[@CppNuts]

Sure, wait for some time.

[@michadudkiewicz3902]

15:36- that's not true what You are saying here. Actually using these two keywords (override and virtual) in same method will give You a warning while compiling saying there is no point in marking an overridding method virtual as all methods that override are automatically virtual (as You mentioned in the beginning, but somehow forgot about the fact) :)

[@ibrahimkeita2839]

So if i understand correctly, you can only override functions in the derived class and not the base class?

[@CppNuts]

You can override function from both derived and base class.
It's just that if you want to override base then you will inherit base and override or if you want to override derived then you inherit derived class in your class and then override meaning whatever you inherit you can override.

hi @CppNuts,
We can use double pointers in polymorphism?

[@CppNuts]

what do you mean by using double pointer in polymorphism?

[@harshalshirole2157]

How we can use double pointer in Polymorphism?
is It possible or not?

Which IDE is this?
Because in our college they still use Borland's Turbo C++ 3.0

[@CppNuts]

Its sublime test editor, but you will have to attach compiler with it.

[@pritamdevdare5232]

please tell me how runtime polymorphism actually applied?

[@biswaranjan3550]

Hello Sir I have one doubt why function overloading cannot distinguished with there return type any specific reason .

[@CppNuts]

One reason i could say is, it would be very much confusing and compiler will have to do hell lot of work to actually verify that it is binding to the right function. And another thing is i really fail to see any benefits of that. So may be its of no use so this feature is not provided.

[@aparnasa8688]

Why function overloading when we can use template classes?

[@CppNuts]

Let's suppose you want to add two variables so if they are int, float, double, sort then it is fine you can use one function temple and it will work, but if data type is char then you don't want to add you want to append them then you need explicit function in case of char. Now you can overload that function with explicit char data type.
So we need both.

[@KaramAbuGhalieh]

you did not made it clear about overriding with different parameters

[@AshokKumar-mk1nr]

Thanks for the videos...
Can you tell, How that object calling works, like c3 = c1 + c2.. c1 contain 1,3 and c2 contain 2, 5, then c3 = c1 + c2.. when object c1 called how c2 takes as reference, please make it clear once..

the runtime polymorphism examples are poorly chosen.

Can you explain how virtual functions are implemented internally?

Sure..
