Abstraction is one of the most important Object-Oriented Programming principles that confuses many beginners. The idea of abstraction is to show only the most important and essential information while hiding the unimportant and complex details.
There are many examples of abstraction in real life:
- When you drive a car, you don't need to know how the internal components of the car work in order to be able to drive it. All of that complexity is hidden behind simple procedures that make the process of driving a car easier.
The same rule applies in programming. When we make a class that has a lot of functionalities, we can hide the inner details and complex logic related to these functionalities behind a simple interface that will make it easy for other developers to use our class, without having to know how those functionalities are implemented.
In this video, I'm explaining what is abstraction, how to use it, and its purpose in real-life examples and using C++ code as well.

I have a question.. @13:14 Why we did not use /* Android* android=new Android(); */ instead or maybe /*Android android; android.TakeASelfie(); */

@EvilSapphireR 2 жыл бұрын

@@footballCartoon91 Because that is the entire point of abstraction. The client code doesn't need to know anything about the child classes (implementations of the interface), not even the names of the child class. You can visualize this as the actual code of the Iphone class methods being implemented in a already compiled library that has simply been shipped to you , and all you've been told is you can get a smartphone from this library by calling a API like [Smartphone *GetSmartphone()]. Then you, as the user (client developer) of library, to take a selfie with a smartphone would simply write : Smartphone *s1= GetSmartPhone(); s1->TakeASelfie(); If the library now changes to a Android smartphone library, the actual TakeASelfie() method code would now be different since this is now an android smartphone and a different library, but you, the client developer, don't need to change the code one bit! That's the beauty of abstraction.

Amazing - the power of abstraction and your intuitive and clear explanation of it. Thanks!

@matrixtoogood5601 2 жыл бұрын

My takeaways:- 1. Abstract classes are an abstraction around base classes which can be used to enforce certain functionality in all base classes. 2. Abstract classes can be instantiated using pointers only and not by creating objects of the abstract class. 3. Abstract class pointers can point to memory addresses of instances of any of its base class 4. Pure virtual functions can be used to enforce certain functionality in all base classes of an abstract class. 5. Pure virtual functions will not have an implementation in the abstract class definitions, but will use a pure specifier (= 0) 6. Virtual functions can have an implementation in the abstract class (think of it like the default functionality if none of the base classes have an implementation of that function)

@jojo_v5395 3 жыл бұрын

come from virtual fonction and abstract function. So grateful for what you're doing. I would say this is the most outstanding explanation video for abstract functions I've ever seen. this is a good example of using coding as a weapon to help more people. That's my purpose too. So Thank you so much

You are the best teacher on KZfaq good job Saldina Greetings from Spain. saludos desde España

@EvilSapphireR 2 жыл бұрын

This is, hands down, the best tutorial that I've seen that lucidly describes the abstraction standard C++ was invented for. Only thing that in my opinion that would improve this explanation is to briefly mention how the definition of the Android/IPhone classes can be in a completely separate library that the client code only needs to link to and get a pointer to the interface of the object from an exported API without knowing anything about the library code. This would make the process of abstraction completely clear to a newcomer who still may struggle with this example since the implementation of the class methods are inside the same page (translation unit) as the client code that invokes the methods. Seriously, amazing job, and thank you!

So an abstract class can help ensure that things are following a kind of convention so that actions can be performed in a similar manner across different objects of that type. I suppose this is even more important when working on a project with multiple coders as well as keeping things clean and readable.
