I have a question.. @13:14 Why we did not use /* Android* android=new Android(); */ instead or maybe /*Android android; android.TakeASelfie(); */
@EvilSapphireR2 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.

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!

@matrixtoogood56013 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)

Thanks for the video it was really useful. In general, abstraction is about two things: 1- Hide the detail of implementation. 2- Generalize by identifing common essense. here in your example you folllowed these two goals.

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.
