can't wait for your course, your videos are the best, after months of struggling to understand programming, i now understand everything with your videos, and i even won a coding competition thanks to you
Thanks for this video! Copy constructors was one of those things that was confusing for me. It's difficult to test for deallocated memory so I could never be sure whether or not I copied correctly without having memory leak.
your videos helped me to finish university, I'm waiting for your practical programming course now to crash my internship. sending love for you codebeauty
Very good video. I always enjoy watching your videos and being reminded of concepts that I haven't used in c++ that I haven't used in a long time since at work I've only been working on VB projects.
BIG thank you for making this video!!!! Your videos are so comprehensive. I hope you will continue making a lot more good content like this. You truly inspired me
Thanks for your video. Absolutely want to hear more about assignment operator or the Big Three. Appreciate that if you can also talk about deep copy vs shallow copy.
It was really an awesome lecture on copy ctor, you cleared my all doubts in 1 go. i request you to please make a seprate video on copy assignment operator too, or diff b/w copy ctor and copy assignment operator!
thank you for this video dear saldina, when will your course be available, i already subscribed to the waiting list and i can't wait for it. love you so much, and thank you! 🥺❤
Appreciated. I think it would have been even more helpful not using pointers, but demonstrating how you still need to do the copy constructors with modern C++.
yes I searched a lot for the copy constructor why we use the reference in the argument of the copy constructor instead of the simple object .. but this video is really very good to understand it … thank you so much .. and please make the video on the assignment operator and the copy constructor in detail....please
Error: the argument to a copy constructor must be by reference. See standard in §12.8/3: A declaration of a constructor for a class X is ill-formed if its first parameter is of type (optionally cv- qualified) X and either there are no other parameters or else all other parameters have default arguments.
I think what you mean at min 12 is that you have a circular dependency, I already knew about that array trap, Can you do a follow up on the copy and move assignment operators
@CodeBeauty Why the compiler not implitly provide a default copy ctor while there is only a custom constructor and a `Book(Book)` method is defined? If the compiler does so, the `Book(Book)` should work. See 11:25 of the video.
The line "Book 3;" with the class example in the video called "Book" will create a book class named only 3, so it will give you an error when trying to assign it to b1. If the question you were reffering was with the code: Book book3; book3=b1; It would have invoked the copy constructor, even though it could have been written as "Book book3=b1;"
Hello saldina, please make an tutorial about constructor. Especial about konfig list. There are Things beyond assigning init values to member values and simple heritage . What does the Compiler do with Text between colon and curly bracket in Detail. I really found nothing about this speaking to me. Thanks a lot!!!! Manfred
You do explain very well. I have to say that. However, there is a missing part: copy constructor invokation during return by value. I guess the video was already too long.
Hallo Saldina , thanks very much for your tutorial it Help me a lot to understand the concept behind. My question is about the call by value & reference. You Said call by value send the copy to the callee function or variable, that one is okay for me , but when it come to call by reference, due to the fact that it passed the original to a function. What will hapen if the callee function modify the original and that somewhere in the Code other functions need the original value that had been modify. This Situation give me nightmare when working with large functions 😢😢😢. Thanks very much for your Help.
If this was hard to understand, then you probably lacked some knowledge before this video. Did you watch my video about constructors and destructors? If not, them you must watch them before you can understand this topic, because they are prerequisites for this video 👋👋
you should definately do a move constructor video for instance, a move constructor: class A { public: std::vector v; std::string str; std::mutex m; A() { v.resize(100); str.resize(100); } A( A&& a) noexcept { v = std::move(a.v); str = std::move(a.str); } void printAddresses() { auto print = [&](const auto& c, auto pointer) { std::cout

I came here for the copy constructor but kept looking at the breasts. I wish I could see more of them. Is there a way to do that?
can't wait for your course, your videos are the best, after months of struggling to understand programming, i now understand everything with your videos, and i even won a coding competition thanks to you
cool! congrats!
Hey!! Congratulation❤❤
I love how you explain c++❤ very clearly
How on the earth you make your every elucidations too simple. I really appreciate it ❤
I gave up programming in c++ years ago ... You gave me hope to rethink my decision ....
Thanks for this video! Copy constructors was one of those things that was confusing for me. It's difficult to test for deallocated memory so I could never be sure whether or not I copied correctly without having memory leak.
Thank you this video. Great to see C++ thriving. Please ignore the stupid and humiliating comments. Looking forward for more content.
your videos helped me to finish university, I'm waiting for your practical programming course now to crash my internship. sending love for you codebeauty
Best C++ tutorials
Very good video. I always enjoy watching your videos and being reminded of concepts that I haven't used in c++ that I haven't used in a long time since at work I've only been working on VB projects.
can't wait for your practical programming course saldina. i already signed in and i'm sure it will be amazing

Please make a video on assignment operator!
Thank you for your time
completed the whole playlist. Best way of explaining oops.
will want to know more about assignment operator as well.
Very nice Saldina.
I 💕💕 your videos on c++
thank you for this video dear saldina, when will your course be available, i already subscribed to the waiting list and i can't wait for it. love you so much, and thank you! 🥺❤
Your explanation is marvelous, as a beginner, I have a better knowledge about copy constructor. Thanks and please keep going
🥰❤️
Amazing Explanation!!
Good explained! Do you have video or maybe you are going to prepare explanation of move constructors?
Appreciated. I think it would have been even more helpful not using pointers, but demonstrating how you still need to do the copy constructors with modern C++.
Thank you for your videos. It helps a lot!

thank you ....miss CodeBeauty Godbless you miss...
what app you use for screen record and edit your youtube video
do you have any videos on object compositions?
Great example, thanks
@CodeBeauty Why the compiler does not implicitly provide a default copy constructor to make the `Book(Book)` work? see 11:25 of the video.
I am from indonesia ...i like learn this is chanell CodeBeauty ...
Plz make a video on move constructor
I think what you mean at min 12 is that you have a circular dependency, I already knew about that array trap, Can you do a follow up on the copy and move assignment operators

have you created any video for assignment operator? Please can you share the link
Thanks.
amazing video, thanks saldina
I would like to see the difference between copy constructor and assignment operator
I'll publish that video next week 😄
Thank-you, I never knew that. Pretty important information to know.
you are too good!!
i really love your videos! thank you for the content : D
Ok. Very nice.
Could you pls make some videos on visual studio for developers so that they can be efficient while debugging and development.
question:
Book 3;
book 3 = b1; // this invokes the copy constructor right?
thank you for the great video
The line "Book 3;" with the class example in the video called "Book" will create a book class named only 3, so it will give you an error when trying to assign it to b1. If the question you were reffering was with the code:
Book book3;
book3=b1;
It would have invoked the copy constructor, even though it could have been written as "Book book3=b1;"
Can you pls make a video about move constructor and move semantics its really hard topic for me to understand

Thanks a lot!!!!
Manfred
thank you very muchhh!
Very well explained! Thanks for the video. Would it be possible to make a video about move constructor? Thanks!
Well touch of cpp
How do you not have the default constructor? When I didn't my code have errors.
If you need a parameterles constructor but you don't have it, you'll get errors 😊
@@CodeBeauty Isn't it essential?
Wonderful
Hi Saldina, I have already subscribed to you, and I want to copy assignment, move ctor and move assignment ctor video. Thank you for your hard work
Thanks!
Thanks 🥰❤️
Life saviour ❤❤❤❤❤
please work hospital manegment system in c++
I'm waiting for explain static members and functions please if you don't mind 🙏
Awesome thanks ❤
You do explain very well. I have to say that. However, there is a missing part: copy constructor invokation during return by value. I guess the video was already too long.
why does c or c++ even pass by value? Why not pass by reference all the time? what is the benefit of passing by value?
i really can see ++
Cool, when unit testing and ndk? 👻, pls🙏

So to prevent the stuff you mentioned above, let use const keyword for the original.
difficult method u used to teach please keep it simple to explain

@@CodeBeauty dear , i already know how it work .. but your teaching way , somehow make's me difficult to understand
a7ssen osstada f l3alam
Wlah nadia
how to do deep copy in this??@CodeBeauty
i love what she is wearing
you should definately do a move constructor video
for instance, a move constructor:
class A {
public:
std::vector v;
std::string str;
std::mutex m;
A() {
v.resize(100);
str.resize(100);
}
A( A&& a) noexcept {
v = std::move(a.v);
str = std::move(a.str);
}
void printAddresses() {
auto print = [&](const auto& c, auto pointer) {
std::cout
I dunno, I like the simplicity of just deleting the code that is causing my errors. 😂
Error exception! Code not found! ;-)
Very good video, however I was pleasantly distracted 😉
😉😉
@@muhammadtahasarwar2110 You know what I'm talking about 👍
@@ted2704 Oranges are pleasent and inviting especially in Summer; so yes they can be distracting
I want a video on data science.
Saldina❤😍
very good video , but it's hard to focus on the code when i see u
"Like this"
Watched 2 times but only focused on two things
ur disgusting
I usually watch tutorial videos in 2x. Not this one though ;)
