I'm learning C++ now, and these videos showing the code being written while explaining the concepts are most valuable.

"oh man, this hair today, it's just, just perfect" - xD. I love it. xD

even though i know 99% percent of these stuff, i still watch the whole video for cherno's wisdom nuggets

I'm a Computer Science major and with the whole online learning thing, its been a but hard to learn things. Thanks for these videos !! They really are a big help.

Had been programming since decades and love ur description. It gives a new way of thinking and understanding.

I go back and watch these videos every time I forget something. And Cherno always gives me the answer

Love the way you explain these things. The way you explain things is exactly the way I like to learn. Very talented teacher. Thanks

Cherno has helped me massively in my CS education these last few years. Thank you so much, my Ozz brotha.

You‘re doing a very good job at explaining the things. Thank you for sharing that with us.

Your tutorials are great, you edit out when your not talking to reduce the tutorial time making learning faster. You also talk fast and don't stutter also reducing the time. Its quick and concise unlike some people that don't do any editing and just talk without much idea of were they are going from there.

Personal notes: - Example: “Cat : Animal” now Cat class has not only type cat but also has type Animal. That is, it is actually both of those types -Polymorphism ~= being able to use the same fuction for different type of objects thanks to inheritance

you explain things so clearly and concisely, really helps with my c++ textbook and examples for class. The textbook is actually great but this video is more compressed and helped me get a clear understanding easily. I tend to use these videos as a supplement to what i'm learning in class and it helps so much. Thank you for taking the time to explain this.

Fast, summarize and precise. Good job man. Love to know you

this guy is amazing, taught me something in 8 minutes that my teacher failed to do in a whole semester

Excellent. It is good to have this video and have a look at it every time I forget something.

Thank you for explaining it that well, this looks super useful.

That light coming through the window is somehow ethereal.

YOU HAVE EARNED ALL MY RESPECT , I AM LEARNING EXCITING THINGS FROM U SINCE 2019 WHEN I STARTED C++ FROM TIME TO TIME IF DONT UNDERSTAND SOMETHIN I COME TO THESE VIDEOS OF YOURS ,YOUR VIDEOS ARE APPRECIATED

Speedrun of learning. I loved it :D

This hair today, perfect. Only took 8 hours of restless sleep to make.

Notes: Inheritance is one of the most fundamental and powerful part of classes. It allows us to have a hierarchy of classes which relate to each other, it allows us to have a base class which contains common functionality and then it allows us to branch off from that class and create sub-classes from that initial parent class. The reason why this is so useful is because it allows us to avoid code duplication. Instead of us repeating ourselves over and over again we can put all of our common functionality between classes into a parent class and then simply make sub-classes from that base class, which either change the functionality in subtle ways or introduce new functionality. The idea behind inheritance is that it gives us a way to put all of our common code into a base class so we don’t have to repeat ourselves.

Thanks! Love your videos man

This is exactly what i learned, is avoiding of code duplication, but many peoples doing tutorials don't understand that and they do it opposite way. Misleading many peoples who want learn inheritance.

Just found your channel studying for my data structures exam, really great content! I'll be checking out the rest soon!

Thank you for making this.

Really awesome, Thankyou so much dear

class BjarneStroustrup { // stuff }; class TheCherno : public BjarneStroustrup { // extra stuff };

Hey Cherno! Love you're videos man, please keep it up! I am quite experienced with C++, been programming for almost 4 years now. I just have couple of question regarding these tutorials. Are these tutorials going to be made with c++14 or up standart in mind? I find it really hard to find quality modern C++ tutorials online.

After watching this video, I finally understand inheritance. All of the other tutorials just made no sense to me.

Perfect example. The example of having different entities inheriting from 1 main class for the generic entity stuff makes complete sense

biggest issue with my murach's textbook. it tries to teach inheritance with a MASSIVE project of code. having a base class with 4 subclasses and other forms of nested functions without showing the entire code. this video kept it simple to teach the basic principle of inheritance. well done.

"Types in C++ are quite a complicated topic because on one hand they don't really exist, however on the other hand they kind of do." is just perfect.

excellent job

Great video very helpful explanation 👍

Your videos are perfect. It would be great if you made video about multiple inheritance! Thank you.

did this man just explain polymorphism in 23 seconds? (mind = blown)

That lens effect is like the default post processing setup in Unreal but with better bokehs.

Great video

This was your clearest video yet.

thanks for your videos, there are really helpful. which one of them is talking about overriding a function?

Hey Cherno, I have been enjoying this series on C++ and learning a lot from you, but as far as I can tell, you have not done a video on polymorphism like you suggested you might in this video. I would love to see that from you. Cheers, Russ

thanks bro

Hi thanks for good videos . Please make a video on friend classes and functions.

you are the best

3:09 Schrodinger's cat

If you say 'Exactly' in a whole 10 hours video again and again i can watch it

perfect timing for exams

interesting concept. Subclass actually contain more from superclass.

thanks a lot~

at the end of the video had me in laugh :D :D

great video, still need more in depth stuff...

You should have covered the protected keyword

Thank you .. 🌹🌹

I've had this model for understanding inheritance for years. It's adequate until you learn about multi-ctor call and ctor initializer list, polymorphism vtables/vptrs, object slicing problem, and multi-inheritance and the diamond-inheritance problem. You then have to refine this basic understanding of inheritance to include the idea of "subobjects": if B inherits from A, it's not that B just has members from A, B actually "owns" a subobject of type A. In addition, to create a B object, the ctor of A must be called to initialize B's A subobject. Subobjects can be seen in visual studios while step debugging. When you inspect a B object, you'll see that it contains an A subobject!

My book and teacher are terrible. You have taught me what was making me second guess getting my cs degree lol. Stress has been slightly lessened! I still have an A in my c++ course but I’m starting to become a tad concerned on how all this operator overloading, inheritance and polymorphism is making me struggle..

Use ctrl + f5 to build-run and keep the console open.

Hey man! Love your videos! I have a question. Before you write your programs do you plan them out on paper? If so, can you share how exactly you do this and when do you know that you're ready to start writing code? If anyone else can share their method, please do. Thanks!!!

How do static variables get inherited? Is there still just one copy for all instances of BaseClass and its subclasses, or is there a separate copy for each of its subclass types?

Amazin

Epic

So why is inheriting different than including? for example: if in this video we included the Entity class inside the Player class.. will this be the same or there are differences?

I have an exam tomorrow and this is very helpful. THANK YOU!

hey one question. can we not have a function and a class of same name. for eg if we write void player(float xa,float ya) and we have a derived class player. if we create an obj and try to call the player function it shows an error

the end lol

May I request a video on virtual inherence please?

Is there also a video about Composition... i mean they say try to avoid Inheritance as much as possible. Use composition.

Tell your teacher this: "This is how you teach."

Question: So if we have two classes split between 4 files, two headers and two cpp files, we only need to use #include in the child class?

Great

Hey, can you make some tutorials for parallel programming in c++ ?

Really good video. Can you explain why ` class Player : public Entity ` needs the public, whats the purpose of the "public " ?

Hello :). Love the videos. Thank you so much! Have you made one on polymorphism yet?

is the __declspec and stuff like that explained in the c++ series?

Why don't the functions PrintName and Move occupy any memory in the sizeof calculation? Wouldn't the object need to hold a pointer to them, at least?

What happens if you change "public Entity" into "private Entity"? does private make all the Entity fields and methods only accessible to player?

could we just move printName to entity class ? and how its gonna look like ?

good

hair god

Is it better to write the Player- and Entity class in the same cpp file (Entity) or would it be cleaner to make a new file for the Player class?

I subscribed because we share the same fashion statement.

I'm only going to learn C++ if you promise my hair will look as cool as yours!

After this video, something is missing. How to reuse the constructor from super class?

oh we aren't even scraping the surface *sees 27/95 oh yea we aren't

Super! But sometimes the subtitles disappear somewhere.

I Always see the line "priorise composition over inheritance". Can you explain this concept in c++ ?

so it is basicaly the same concept of a function but for classes.

How/Why do the variables X, Y get initialized to 0? player.X = 0; player.Y = 0; Yet, entity.X and entity.Y are uninitialized???

3:08 lmao

I tested the same code, somehow I get total of 16 bytes but not 12 like you presented in the video? Is it something wrong with my machine or setup?

showing off to my high school teacher

i am new to c++ can any explain what is meant by this statement i could not find answer to this online in example give in video class Player : public Entity::something ::something can anyone explain this what is meant by above state have seen similar in a code base trying to understand

And when you want an entity that can't move...?

hello , the size of char is 1 byte ! so the size of const* char Name is equal to 1 byte and not 4 bytes !

Hey guys, hoping somene can help with a syntactic doubt here, english is not my native language so sometimes I struggle a bit.. In the example of the video, would it be correct to say that the functionality of Entity class is inherited to the Player class?

👍👍👍

pls show altr for super key word in c++

How do I use the const char *name ?

can someone please answer me , why did he use const char instead of just char

Everyone out here in the comments talking about how they're computer science majors while I'm just bored.

Now your name is "Acherno" !?
