Advanced Inheritance & Polymorphism - example with Array of Objects (in-depth Data Structures & OOP)

This video provides an in-depth explanation of the relationship between Arrays of objects and OOP concepts such as Inheritance and Polymorphism. It is a programming tutorial designed to teach you about data structures, object-oriented programming, and best practices for writing code. Through a practical example, you will learn how to create arrays that hold a collection of different objects. By the end of this coding exercise, you will have a solid understanding of how to implement parent-child relationships between classes and write reusable code. Additionally, you will learn how to implement polymorphic behavior and write efficient code.
To put your knowledge into practice, I have also prepared a practical task for you. This hands-on challenge will ensure that you understand these concepts and are able to use them in your own programming projects.

standing ovation for this video, your effort in simplifying these concepts deserves a big round of applause

[codeoasis]

your breakdown of arrays of objects, along with insights into polymorphism and inheritance, has given me a solid grasp on these topics, thank you Saldina

[dundyd]

You're an excellent teacher, and have a great gift to explain these complex topics so well. I admire you even more now that I know English is not your native language!

[deanmorrison]

just wanted to drop a quick shoutout for your video, your teaching style rocks, many thanks

[Sam-kii]

hey there Saldina, your video seriously helped me wrap my head around complex programming topics such as this one, just wanted to say thank you <3

[MilesGerome]

can't thank you enough for this video, you are truly empowering me on my coding journey. Fantastic instructor

[anwar]

Thanks, watching all these series of videos related to array of objects

[lamienali]

Thank you for this insightful lesson your coding videos are incredibly valuable for learners like me.

[milkamilkica]

excelent explanation as always, thank you Saldina

[l.p.]

i wish there is more instructors like you, thanks <3

[OzzFan]

Excellent explanation on inheritance and polymorphism! Thank you so much.

[hilgicamala]

great content Saldina, superb explanation, thx <3

[pedrolobo]

Hi, can you please make a video about Lybiscovist Substitution Principle? This is deeply related to this topic.

[HexShank]

Your videos are filled with highly inspirational and generous instructions. Thank You Saldina Thank You. You’re by far the best most legendary C++ instructor I’ve ever met over the internet. Be well Saldina. Peace and Blessings through our Blessed Mother.

[lamienali]

Could you possibly delve into the use of different scripting languages like Python and C++ to create a login page?

[nvusb]

just what i needed, thank you Saldina

[christopherrice]

I thought English was Saldina's native language. What IS her native language then🤔?

[salihbarknakkaya]

Well it is done. I watched all of the oop lessons here. It was totally a masterpiece. I will do more practice and in a few days I will start data structures playlist in your channel. (maybe pointers as well) Thanks for the all cool informations, It was the best so far I have ever seen, u r great!

[johnmichaelisaac]

I didn't know I could do arrays of pointers for every object I make. This is super helpful thank you so much, learned a lot just from this vid🎉
