@@unitornsreal class is a blueprint right? so abstract class is like a blueprint of a blueprint or simply abstract class is a blueprint of default class and virtual function in abstract class have 0 means the child or subclass inherit for that abstract class need to implement that function because if you do not you'll get an error (virtual function without 0 it means that the function has a default implementation in the abstract class like; virtual void makeSound() { cout
@@unitornsreal Abstract class in C++ has at least one or more unimplemented functions which they call pure virtual function. The reason why it is set to 0 is to indicate it is a function that needs implementation for you to use that class. Hence you cannot create an object of abstract class instead it is inherited into another class where the pure virtual function must be implemented. The reason why it is used is to achieve polymorphism meaning it has many forms. Think of an example where you have a function called shape now you could have many different types of shapes so you keep the method shape() abstract so that the class implementing the abstract class can define what shape it intends to make or display.
My C++ college course was so insufferable that I thought I'd never like C++ but you explain it so well and uncomplicated that woke my interest in this language and I may continue learning it. Thank you so much!

I have just finished Saldina's course on her TH-cam channel. I started from the basics and then progressed to functions, data structures, pointers, and OOP. Now, I am revising OOP and I believe that after I finish watching this course, I will follow my own path. I think it's a good time to start learning and creating something by myself, using documentation and other resources. Thank you, Saldina, for everything.

I have been studying all kinds of complex subjects for decades with some extremely gifted teachers at times; still, this is one of the best classes I've ever seen.
Hi beautiful Saldina! I'm a Java italian programmer since decades; I studied and used Ansi C 99 in my past but I always got a gap (or a hole in my brain) about C++; many thanks to your quick and direct tutorial now I can connect lot of dots that I never knew; Java is clearly a huge help to understand your lesson, since the OOP rules are the same and the implementation quite similar. GRAZIE e CIAO! 🙂
The video was incredibly helpful! It clarified the C++ OOP concepts that I had been struggling to understand. I now have a much clearer grasp of them. Thank you so much, Saldina Ma'am!
I just want to say thank you. Thank you for making coding simple.

I dislike online schooling for the simple fact that words are only as useful as the way you interpret them. And your style of teaching is simplified, useful and can be interpreted by any listener.
Day after tomorrow I have C++ exam, I had knowledge about procedural programming language(c) and about classes before watching this video. I swear that I have understood all the concepts explained in this video and I have implemented them in vs code by my own. Found this video very much helpful. Her way of explanation is remarkable. Hats off to you. Love from India.
Saldina, I have been watching this tutorial for under thirty minutes and you have already helped clarify the majority of the questions that I had prior to watching. Thank you! Please, do not take it the wrong way, but I love you. You are awesome. I have been teaching ESL for over ten years and I am learning to develop in the blockchain and you have made things rather simple for me. I love you so much!
to be honest what i aint learned from my teacher in more than three months, I just learned here in one and a half hour video. You did a great job keep it up!
True... most colleges have a introductory OOP class. And they spend a whole semester to cover the topics which are all included in this just 90mins video.

i normally get bored or distracted while watching programming courses like this, but somehow she was very engaging. it was as good, if not better than a 1 on 1 lesson. learning cpp from python has been seeming quite difficult but with this lesson it started to feel much easier :)
Yeah I wonder why... lol... Also, scrolling through tiktok can decrease attention spans… Lastly, watching any tutorial is easy but implementing what it covered actually addresses what we’ve learned.
"As you can see we have an error, but it's a different error. Which means we're making progress!" This sums up everything I'm doing in college and in life 🤣❤
Thank you for explaining how Inheritance works. In our class, we use headers and implementation files, but this works the same and it helps make more sense.
Amazing Tutorial. Tomorrow is my exam for OOP and i already studied a lot on it but this single video cleared my many concepts. Thanks Salina and i'm already watching your tutorials.
I've watched so far just 30 min from it and this is a very good tutorial . I am gonna put in Visual Studio every second from this tutorial Thank you very much ! I hope there are more and will be more on your yt-channel Edit : wish you the best !
I'm amazed to see how the IT industry helps people to get desired qualifications and new skills and most of it for free.. it's a wonderful community .. huge respect and love
Very well done. You've done in little more than an hour what my teacher refuses to do at all. We're well below his contempt, it would seem. I've finally understood why this can be fun and powerful at the same time.
I must thank you for making this wonderful video. I am a beginner in C++ and I truly benefited from this very well organised teaching. No other videos have come close to this one.
Hi Saldina, I watched the whole video and it was awesome. I understood all the concepts very clearly and I want to thank you for teaching so well to us. Hope to see more such informative videos soon.
We can't access the properties directly because they are private. That's why we need to use the getter in the derived class. Okay you already answered 😂 my bad P.s. Amazing explanation. I was lagging behind in OOP concepts but now i have a much clearer idea! much Love💕💕💕
I don't know how much this video solidified OOP for me. CodeBeauty is amazing for this tutorial! Very straightforward and easy to code along with without getting lost. Thank you, thank you, thank you!
I wish you were my cpp lecturer.. feels like at my collage nobody knows how to teach after watching the whole playlist in 2 days. Thank you Saldina! You are the real Beauty not the Code :) ♥
Basically, CLASSES are a collection of more than one same or different data types. Simple. Thanks for the simple explanation by always giving daily life problems as examples. This really helps me in learning fast.
Perfect explanation, simple enough, to start with C++, i definetely recommend this course some one else. You really know the subject in deep and clearly explain it. I just have one question, by creating public getter setter methods, i try to understand that, in what sense we avoid our props in private? In anycase they still can read/write it. By means of that do we protect their data type ? So they can not change data type but they can read the value or load a value. This part is not clear on my mind? I d appeeciate if you can explain how do we protect them ?
> I just have one question, by creating public getter setter methods, i try to understand that, in what sense we avoid our props in private? Not everything gets setters. The point of encapsulation is to prevent an invalid state as a result of a series of member function calls. The simplest example would be to have a dynamic array of int class with member functions like so: ``` class simpleArray{ /*private members*/ public: // inserts at the back void push_back(int); // removes last element void pop_back(); // returns size int get_size(); /*constructor, operator[], etc...*/ }; ``` If we call our member functions in any order, as many times as we want, then check size, there has to be no way, such that the size is wrong ie.: size=/=min(0, (count_of_pushes - count_of_pops)) given the array was empty at the start of the test. set_size(size_t); would allow us to shoot ourselves in the knee, so we don't create it.
@@b1rds_arent_real thank you for the explanation. You mention about to validation of the method calls, right ? I still stick on my question, how actually we protect a private property lets say private: int age; so we create extra methods to assign a value for this variable, of course we can validate the input here. But still it is accessible out from class. So this the point that i could not understand encapsulation thanks in advance
@@volkangundogdu1008 Let me start off by saying your intuition is awesome and you should definitely persue coding. As you've pointed out, a setter in this case isn't a great call. In a realistic scenario, you'd not have a set_age(int) at all. You'd have something like increment_age(), which increments it by one and says "Happy birthday!". Her example in this case is quite bad, since something representing a person doesn't grow younger suddenly or get from 32 to retirement age.
@@Ihavetoreturnsomevideotapes A, we found the 15 year old edgelord with no opinions of his own who repeats the latest fashionable terms of his peer group...
I'm about to take this course next semester, and I appreciate your effort to explain a somewhat 'scary' concept to me in very simple terms. Having taken a course in python before and not understanding its OOP fundamentals has been pushing me away from learning OOP again for a long time. Thanks!
Amazing tutorial, thank you so much! One question though! At 26:14, is there a good reason to write: Employee employee1 = Employee("Saldina", "YT-CodeBeauty", 25); instead of: Employee employee1("Saldina", "YT-CodeBeauty", 25); ? Or is it just a matter of personal preference?
@@tomatocultivator2456 No, it does not matter, I believe in Java Script you would have to say "Employee employee1 = New Employee("Saldina", "YT-CodeBeauty", 25);" notice the new just after the equals sign. Im assuming she has experience in Java Script and does this out of habit.
I cannot imagine more excellent explanation than this one. You are the sweetest, the most amazing person on the planet. Enjoyed every second of the video. Thank you!!!
@@santiagooarg6990 actually what happens that when ur in college no matter u r tired or not in mood to study u have to attend the lecture but in home we mostly study these concepts when we are in a mood to study. i will give u a suggestion that study the topic before ur teacher teaches and see u will start to understand them very easily. btw ik my english is not good

i normally get bored or distracted while watching programming courses like this, but somehow she was very engaging. it was as good, if not better than a 1 on 1 lesson.
learning cpp from python has been seeming quite difficult but with this lesson it started to feel much easier :)
Yeah I wonder why... lol... Also, scrolling through tiktok can decrease attention spans… Lastly, watching any tutorial is easy but implementing what it covered actually addresses what we’ve learned.
"As you can see we have an error, but it's a different error. Which means we're making progress!"
This sums up everything I'm doing in college and in life 🤣❤
Damned spoilers!
My life, except for the progress bit!
lmfao I salute your honesty!

Thank you for explaining how Inheritance works. In our class, we use headers and implementation files, but this works the same and it helps make more sense.
one of the most amazing videos for oops with a clear and to the point explanation!!!! Loved the effort
You can access data from the employee class directly.
You teach more than anyone I can find on the internet.
Thank you, Saldina

Super objasnjen OO concept! :)
Awesome explanation!
The way of explanation is so well that we can easily understand the applications of OOPS in real life problems.
Excellent job.

Finally get this after after 3 years of c++ in university and 3 years of working as a python developer, thankyou very much and God Bless.
CodeBeauty is the best channel to learn C++. Great content.
I've watched so far just 30 min from it and this is a very good tutorial .
I am gonna put in Visual Studio every second from this tutorial
Thank you very much !
I hope there are more and will be more on your yt-channel
Edit : wish you the best !

Вітаю вас з України! Дуже гарний урок, щиро дякую!
Very well done, thank you Saldina! Your presentation of the fundamental concepts was simple and effective! Appreciate you and your passion to share!
What I like most is when Saldina tries to create humour purposefully and she smiles and then she gets serious again within no time
god bless this woman and everyone that is envolved with this channel thanks for the help
Finished the video without getting exhausted. Man, this was so helpful! Keep up the good work.
Everytime I'm thinking of a software engineering topic I'd like to learn a video pops up the same day explaining that very topic.
TH-cam understand you more than your parents, i guess.
Lucky you. I've had that streak sometimes in the past

I'm amazed to see how the IT industry helps people to get desired qualifications and new skills and most of it for free.. it's a wonderful community .. huge respect and love
She explained everything perfectly clear! Best talk I have ever watched.
just covered everything for my end of semester exams in 1.5 hours. thankyou so much
even just 30 minutes of this course has more knowledge than 10 pages of class explanation.
Thank you Saldina for explaining Getters\ Setters ! Especially so simply, I appreciate it ! 😊👏
very good explanation !!!!!!!!!
keep doing more videos and we keep supporting!!
love from india!!!!
Simp
thank you so much, i learned 1hour OOP that is equal to a month of OOP teaching from my teacher ,, thank you so much, im from the Philippines
introduction has taught me more than my lecturers together with thr ancestors.. you are a born teacher
Very well done. You've done in little more than an hour what my teacher refuses to do at all.
We're well below his contempt, it would seem.
I've finally understood why this can be fun and powerful at the same time.
I've learnt many things from this course, Thank you for making OOP so easy :).
my Exams are coming soon i was looking for short course for oop, you saved me ty
You’re a genius. The way you explained abstraction was extraordinary.

I must thank you for making this wonderful video. I am a beginner in C++ and I truly benefited from this very well organised teaching. No other videos have come close to this one.
I attended this class before my job interview and it helped me answer the questions !! Thanks a lot for your wonderful explanation!
I have an interview in 2 days and am watching this video for the same reason
Hi Saldina, I watched the whole video and it was awesome. I understood all the concepts very clearly and I want to thank you for teaching so well to us. Hope to see more such informative videos soon.

We can't access the properties directly because they are private. That's why we need to use the getter in the derived class.
Okay you already answered 😂 my bad
P.s. Amazing explanation. I was lagging behind in OOP concepts but now i have a much clearer idea! much Love💕💕💕
Happy to see a Bengali here🤪
I don't know how much this video solidified OOP for me. CodeBeauty is amazing for this tutorial! Very straightforward and easy to code along with without getting lost. Thank you, thank you, thank you!
She is the perfect example of beauty with brain.
Such a beautiful explanation!
Loved This waited for long time
Excellent video. Learned more in less time than several other C++/OOP tutorials by other folks! Thank you!!
Brilliant teacher, thank you very much
I wish you were my cpp lecturer.. feels like at my collage nobody knows how to teach after watching the whole playlist in 2 days.
Thank you Saldina! You are the real Beauty not the Code :) ♥
Basically, CLASSES are a collection of more than one same or different data types. Simple.
Thanks for the simple explanation by always giving daily life problems as examples. This really helps me in learning fast.
Perfect explanation, simple enough, to start with C++, i definetely recommend this course some one else.
You really know the subject in deep and clearly explain it.
I just have one question, by creating public getter setter methods, i try to understand that, in what sense we avoid our props in private?
In anycase they still can read/write it.
By means of that do we protect their data type ? So they can not change data type but they can read the value or load a value. This part is not clear on my mind? I d appeeciate if you can explain how do we protect them ?
> I just have one question, by creating public getter setter methods, i try to understand that, in what sense we avoid our props in private?
Not everything gets setters. The point of encapsulation is to prevent an invalid state as a result of a series of member function calls. The simplest example would be to have a dynamic array of int class with member functions like so:
```
class simpleArray{
/*private members*/
public:
// inserts at the back
void push_back(int);
// removes last element
void pop_back();
// returns size
int get_size();
/*constructor, operator[], etc...*/
};
```
If we call our member functions in any order, as many times as we want, then check size, there has to be no way, such that the size is wrong ie.: size=/=min(0, (count_of_pushes - count_of_pops)) given the array was empty at the start of the test.
set_size(size_t); would allow us to shoot ourselves in the knee, so we don't create it.
@@b1rds_arent_real thank you for the explanation. You mention about to validation of the method calls, right ?
I still stick on my question, how actually we protect a private property lets say
private:
int age;
so we create extra methods to assign a value for this variable, of course we can validate the input here. But still it is accessible out from class. So this the point that i could not understand encapsulation
thanks in advance
@@volkangundogdu1008 Let me start off by saying your intuition is awesome and you should definitely persue coding. As you've pointed out, a setter in this case isn't a great call.
In a realistic scenario, you'd not have a set_age(int) at all. You'd have something like increment_age(), which increments it by one and says "Happy birthday!". Her example in this case is quite bad, since something representing a person doesn't grow younger suddenly or get from 32 to retirement age.
We can protect data type only putting a getter, no a setter
@@b1rds_arent_real ya you are right

It's really a organized and informative tutorial on OOP in C++. Thanks Saldina 💌
Very good mam you are always inspiring me
I'm about to take this course next semester, and I appreciate your effort to explain a somewhat 'scary' concept to me in very simple terms. Having taken a course in python before and not understanding its OOP fundamentals has been pushing me away from learning OOP again for a long time.
Thanks!

This a great course. Thank you ^^
One of the best teaching, everything is great. Thank you very much.
Transition at 28:40 is smooth.
This girl could teach me machine code and i wouldn't even complain
...ok
Amazing tutorial, thank you so much!
One question though!
At 26:14, is there a good reason to write:
Employee employee1 = Employee("Saldina", "YT-CodeBeauty", 25);
instead of:
Employee employee1("Saldina", "YT-CodeBeauty", 25);
? Or is it just a matter of personal preference?
Same question.
No, it's just like
sum = a+b;
return sum;
OR
return a+b;
@@SomeoneScary Thank you!
@@SomeoneScary Thank you!
@@tomatocultivator2456 No, it does not matter, I believe in Java Script you would have to say "Employee employee1 = New Employee("Saldina", "YT-CodeBeauty", 25);" notice the new just after the equals sign. Im assuming she has experience in Java Script and does this out of habit.
I cannot imagine more excellent explanation than this one. You are the sweetest, the most amazing person on the planet. Enjoyed every second of the video. Thank you!!!
You are my third try at an OOP tutorial. You win big time. Very concise explanations! Going to watch more of your tutorials.

braah, i feel like the teacher in my university try to explain the concepts in the hardest way possible, or i am just dumb, idk
hey was the subject OOPS? like in madhya pradesh maybe
@@iqrarahman9265 in Bangladesh also
@@santiagooarg6990 actually what happens that when ur in college no matter u r tired or not in mood to study u have to attend the lecture but in home we mostly study these concepts when we are in a mood to study. i will give u a suggestion that study the topic before ur teacher teaches and see u will start to understand them very easily. btw ik my english is not good
If she was she was my teacher... I promise I would never missed her class😊 and would have been the best student in the class with lots of doubts😁
Thank You So Much for keeping it so simple!
You've got such a positive and warm aura💗
Thank you so much! OOP is thrown in at the end of my current C++ class and I could not get it. You have saved my sanity!
