This guy really deserves 100M+. Really the best RUclipsr. The way he teaches is wonderful. I am from Nepal 🇳🇵, heart this comment.
@THE Programming Fool! Wtf
😂😂😂 nice joke
Summary-
// As we have seen in tut55.cpp that BASE class pointer pointing to DERIVED class object can only access BASE class inherited members which is a default behavior.
// But if you want to change default behavior and want to access the members of derived class by a pointer pointing to derived class object then use virtual keyword in front of BASE class member function.
Exactly
but what if you have passed different arguments to the display function in both the class? its not working then.
If they contain exactly same fn (name and argument) then the BASE class pointer pointing to THE DERIVED class can call only BASE class fn.
To call the derived class fn we declare the BASE class fn virtual

Harry bhai...I have shared your channel to all my friends....I don't know why do you get such low views... ..bhai esa content to aajtak kisine nahi diya.....pura practical samjate ho aap....thank you soo.. much.....
Harry Bhai, i started learning C++ from this playlist on 12th October 2021, and today it is 24th December 2021. It is going to complete soon. Thank you so much for this course.🤩😇 Motivated++
how r u bro what is ur situvation now
i am first year cse student what about u
what uses did u get from this course
please reply it will be usefull for me bro
On 12 oct there is birthday of rm of bts oh im bts army😃
@@sudheepro All the concepts of Object Oriented programming are covered in this course. Once you have completed this course, you will be able to switch to any other language which supports object oriented programming.
The topics are explained to the point, and in a very different manner than other tutorials. The examples given by Harry bhai are still fresh in my mind. ❤️
@@vikasrathore3955 bro operator overloading toh nhi hai isme
@@deepikakar5394 haanji.. operator overloading is missing in this course.
You are the best teacher because you help to the poor people . You had made a lot of courses for us!
NOTE: You can also use "void virtual" instead of '"virtual void "
shukriya bhai jaan
Thank you Bhai for making quality videos for us. I love your videos.
Sir! Your channel is growing really fast
Yes, thanks a lot for all the love and support!
@@CodeWithHarry Thanks for providing quality Content
@@CodeWithHarry sir will you please make some more videos on android development please please bhaiya ji i m in class 8 and i am really interested in programming and also thank you very very much for such awesome and free content 👍😊.

abbbe par isse ye bhi poocho ki operator overloading kaha hai😭😭
Finally Completed this series ! Harry Bhai - Ab taq ki yatra safal ! Bahoot Bahoot Dhanywaad ! Cheers & Peace !
Your teaching method is extra outstanding 🔥🔥🔥🔥
I liked u r videos sir..... I just started to see u r first videos of c++. Iam glad to say that u r videos are awesome
i didn't find operator overloading in your playlist bro
No operator overloading in his playlist
Padhaya hai bhai
@@yogendranathsingh2576 video no. kya hai isme
yeaaa even i could'nt find. so i did refer to Simplilearn for operator overloading and its super easy!!
Great work Harris bhai, kindly also give the concept of Shallow copy vs Deep copy as this question was asked in an inteview on basic level of programming.
THANKS
1:11 literally jab mai easy hota hoon
Le harry bhai:
dehaan se sunna baat ko.
Love you sir 300000 times.... I'm of 13 and I regularly watch your videos please reply
Harry bhai super se bhi uper🤘🤘
Virtual functions in C++ allow runtime polymorphism, where the function called is determined at runtime based on the object type, not the pointer type.
Key moments:
00:00 Virtual functions in C++ allow a function in a base class to be overridden in a derived class. Making a function virtual enables runtime polymorphism, executing the derived class function when called through a base class pointer.
-Understanding the concept of pointer to derived class and polymorphism is crucial for comprehending virtual functions in C++. This knowledge forms the foundation for implementing runtime polymorphism.
-By making a function virtual in the base class, you ensure that the derived class's version of the function is executed when called through a base class pointer. This dynamic behavior enhances code flexibility and extensibility.
06:29 Polymorphism in C++ allows objects from different classes to respond to messages, achieving runtime polymorphism through virtual functions. Compile-time polymorphism involves function and operator overloading for different behaviors based on arguments.
-Explanation of polymorphism in C++. Objects from different classes can react to messages, enabling runtime polymorphism with virtual functions.
-Compile-time polymorphism in C++. Function and operator overloading create different behaviors based on arguments, determining the function binding during compilation.
08:29 The video discusses virtual functions in C++, providing examples and rules for implementation. It emphasizes understanding and practice for effective learning.
-The importance of practicing virtual functions to enhance understanding and learning in C++. Encouragement to create more examples for better comprehension.
-Upcoming content on rules of virtual functions, late binding implementation, and examples in the next video. Emphasis on grasping the virtual keyword and functions.

congratulations bro :)
All dout clear thanks🙏
Harry bhai
Your teaching is really amazing... thanks a lot.. you've changed my life 🙂
Mast hai mast bahut badiya coder hai tu
Great series
watched many videos brother but you cleared all the doubts that i had on virtual function. Thank you😍
Best course for C++
with the pointer of base-type we can use functions of derived class if and only if the base function is virtual,
however, the derived variables won't change with pointer.
U r the best
assalam alaikum bro from pakistan love you you are such a nice guy
Question ?
Bro, as you have said in tut55.cpp, we can use derived class members if we use derived_class_pointer pointing to derived_class. (like base_class_pointer= &obj_derived), so why there is a need of "Virtual functions" to access derived class member function. We can do the same by creating a pointer pointing to derived class (like derived_class_pointer= &obj_derived).
that's was a type of compile time example.., and in that we weren't able to get the derived function functions using base class pointers. So virtual functions is made for accessing the derived class functions using base class pointers.
Wow.. You are amazing👍👍🤩

Harry vai you are great 🔥🔥🔥
please make tutorial on reactjs in one video, very much needed
i don't know why but 5:47 that OK!! was funny XD
U r explanation is always best harry bhai
Thanks Excellent & keep me update time by time
Best tutorial in the world 🔥🔥
thank you sir explaining virtual fuction 🔥 it help me a lot🙂
An important point , we can point an object of base class to an object of derived class but VICE-VERSA IS NOT POSSIBLE.
Thank you very much sir 🙏🏻
This is another easy example of Virtual Function...
#include
using namespace std;
class BasicCar {
public:
virtual void car() {
cout

harry bhai you can create an module in python
which gives the the time and space complexity of program it will be a great module in python
whats your perspective
thank you for your efforts for us
great content
harry bhaiya is great always : our tribal chief --> Acknowledge You bhaiya
very helpful video
Sir muze main function me derived class ke variable ko initialize karna hai to kya muze derived class ka pointer create karna padega?
you missed the operator overloading topic :o
