The OP comment is so cringe.

Computer scientists: "ah yes this is an implementation of polymorphism and encapsulation" Also Computer Scientists: "This some spaghetti code right here"

Encapsulation : grouping related variables and functions operating on them. (Reduce complexity) Abstraction: hiding complex data and methods from user (simple interface) Polymorphism: many forms .. to avoid long if else statements RENDER Inheritance: inherent the qualities of a code (to remove redundant code)

I have tried many times to understand what object oriented programming really is. This was the first successful try. Thanks and congrats for the very high quality video!

For me encapsulation is not only about storing properties together and decreasing number of arguments, but what is more important it is all about HIDING implementation details and PROTECTING code from random access. At the same time abstraction is about ignoring unimportant parts of objects providing only essential interface for 'outer world'.

The harsh reality is, though, that you probably don't understand from watching this video to pass an OOP exam. It takes years to get to a professional level of understanding of OOP. It's a major dedication, as opposed to something that can abstracted and encapsulated into a short video. And that's not even telling you that this video contains errors, despite the speaker's voice being very confident.

This is the simplest, precise and easy to understand explanation I have found until now.

Thank you for focusing in this one topic, I've been having a hard time wrapping my head around this. Your video really helped.

@@One.Zero.One101 I didn't miss the point of what the guy was saying: "College text books are too hard". OOP takes years to get good at, assuming one's brain is worthy of the challenge and the commitment. And yes, I'm tired of people lying on their resume claiming to be good at OOP, when in reality they were just intrigued by a fancy KZread video and have just dabbled in writing classes . I saw one misuse of the word "interface", and then jumped a little past half way and found another mistake @ 4:39 (confusing abstraction with encapsulation). So as pleasing as it may appear to a newbie, they easily could walk away misinformed. It's easy to be attracted to easy material, indeed, but it's also easy to be misinformed and not realize it. That's my complaint about the majority of people who quickly fall in love with an educational video, not realizing the information is not quite right. I think people should read OOP books written by authors with well-established expertise, and not be so attracted to fancy youtube vids.

you're insane man. i'm reaaaaaly proud of having a compatriot like you. you know our difficulties from iran. for example i can't buy your tutorials. so i will be reeeaaallly thankfull if you publish more contents with us.

Thanks, Mosh! I learned a lot! I just learned to code recently, but I am really passionate about it. I hope I can always be a better programmer over time.

This is only of the best one can find! Thank you so much. :)

Encapsulation is just not about making variables private, it is much more. It is about breaking up the application into different logical and organized parts. So that you can change one part without generally changing all the other parts. Therefore encapsulate the parts that vary from the parts that remain the same.

Been programming for 22 years and going to try OOP for the first time. Looks like it will make my programming easier in some aspects. All this time I got away with procedural programming and my current job (programming automation) does not need me knowing OOP but I hope to get a job in software engineering, and I feel OOP is a must to master.

But in reality, you couldn't watch this video and pass a test over OOP. Not to mention the mistakes in the video, where he uses the wrong word, like "abstraction", which has nothing to do with reducing impact of change. So in reality, just because this video made you feel good, you have a long road ahead of you to become an expert at OOP.

I don't even know why I'm watching OOP-oriented videos - I was simply searching for UE4 Blueprints tutorials, so only loosely related topic - but that was a very solid explanation. Thank you, I'm glad I've watched it.

Polymorphism : you gave the best example with inheritance 🔥🔥🔥 many of them will never appreciate it...

Very clear and you make the subject interesting! :)

This is the best OOP explanation i've ever seen. Thank you so much for that!

This was very good, I read 5 different explanations of OOP before coming here, I had the basic idea about the terms but it's definitely clearer now, what each term actually means.

C++ gives you all of those benefits, plus procedural when need along with lambdas, functions pointers, function objects and templates consisting of function templates, class templates, and variadic templates... but c++ also gives you the added benefit when a set of classes that are related can reference or modify internal protected or private members by labeling them as a friend. This doesn't account for the fact that C++ is a strongly typed language, and has various storage type classifiers such as static, const, mutable, inline, etc... Modern C++ also has constexpr which is a very useful precompile feature. Suppose you have a class called Motor this could be a nested class within a Car class, however, you might want the Motor class to be an independent class because you can have a motor in a Boat, a Bike, Train, Plane, ATV, or it can even be an electrical motor to some kind of power tool. So in this situation, your base Motor class would be complete abstract, then your VehicleMotor class would derive from that. Then your derived Vehicle class objects such as a Car would have friend access to the VehicleMotor class so that it can change its internal properties such as HorsePower, NumberOfCylinders, etc. Now the Vehicle Motor class might not be able to access the Car's private members directly but could be a friend to access its private methods or its protected members... This doesn't even account for the preprocessor directives and macros. Yes, many people frown upon Macros, but in some contexts and if done carefully and correctly, they can make for good text expansion and replacement. I wouldn't rely on them for setting or changing values, or passing data types around, but they can still be useful. With the current release of C++20 in which I do not have a current compiler as of yet, we are now being introduced to Concepts, Coroutines, Modules and more! It's just that with C++ you need to know what you are doing as C++ will allow you to write code to shoot yourself in the foot as long as it compiles and links and provided you don't have any run time errors or crashes. You can still have memory leaks, dangling pointers or references, invalid pointers, and references, etc. Other things such as out of bounds indexing or accessing memory that doesn't belong to you will cause unhandled exceptions. Knowing when to cache something into a local variable within its a specific scope or stack frame is vital compared to knowing when to put something on the heap. Dynamic programming is good in many contexts but one has to be careful, that's why the standard library is so versatile with its containers and algorithms, smart pointers, etc. C++ gives you almost all of the concepts of OOP without the garbage collection of C# and Java with very minimal overhead and more. It is also considered a lower layer of the high-level languages next to C and Objective C, any lower and you'd be working with ASM. It is very fast and efficient and when done correctly, the source code for the application or the program is practically invisible as modern C++ compilers are excellent at what they do and are only improving. They aren't completely perfect as they do have bugs, but they can generate object code or assembly code much better than you can! They will utilize specific operating system functionality and CPU instructions in manners that you would never think of! Their error messaging systems are becoming much better along with their linker and debugger tools. I've messed around with C# a little, JavaScript a little and Python but when it comes to the type of programming that I'm into doing such as 3D Graphics Rendering Engines, Hardware Emulators, Sound Processing, Compiler Design, etc. this is where languages such as C, Objective C, and C++ excel above your high-end languages. If you're looking to do something quick and fast such as an online interactive program for quick access and basic functionality then yes, by all means, Java, JavaScript, C#, Python and others are perfect for the job. However, when you are writing the backend, frameworks, libraries, server code, etc. that's where these languages are usually preferred. This is why C++ is considered a multi-paradigm language! It can still work like C, it has the ability to inline assembly blocks as their own scope within a function for optimizing loops, etc. the capabilities such as C# and Java without the overkill of the garbage collection, and it isn't restricted to have everything as a class or an object or a smart pointer behind the scenes such as seen in Python, C#, or Java. However, it is a strongly typed language which makes it a great tool to master! Happy Coding!

"We can change or modify one of the methods and it will not impact the rest of the code" - famous last words ;) Class extending, sharing "this" all around the place, mutating the state - that's all the consequences of OOP and it WILL impact the whole program. Granted - it's all about the patterns. But we all know how you can end up with "Spaghetti" code even with OOP. Not to mention presented "Procedural" programming claims should be also contrasted with Functional Programming since Procedural would focus highly on imperatives rather than abstraction functions. Beginners could easily confuse Procedural with Functional at this point. With that being said - thanks for gr8 video :)
