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?

[@hilgicamala2520]

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

[@I-SOY-SMART]

cool! congrats!

[@saybalroy8393]

Hey!! Congratulation❤❤

[@saybalroy8393]

How on the earth you make your every elucidations too simple. I really appreciate it ❤

[@dhrubajyotisarma6268]

I love how you explain c++❤ very clearly

[@manoking9619]

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.

[@deanmorrison6254]

can't wait for your practical programming course saldina. i already signed in and i'm sure it will be amazing

[@AmyNguyen24-09]

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

[@CodeBeauty]

Thank you, I'm happy that my videos help, and I'm making new videos every week 😄😄

I gave up programming in c++ years ago ... You gave me hope to rethink my decision ....

Thanks 🥰❤️

[@aaronsj80]

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.

[@dundyd3612]

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

[@jhon3991]

@CodeBeauty Why the compiler does not implicitly provide a default copy constructor to make the `Book(Book)` work? see 11:25 of the video.

[@Nibyyy816]

your channel best on youtube related to programming.

[@danny12345]

Thank you for your time

[@ptrblz]

Yes it's confusing, not the constructor themselves though but knowing when which is actually used when you come from simpler languages. But later it's something that really makes your code perfectly effective when you don't copy unless necessary and also utilize move constructors, assignments.

[@muhammadtahasarwar2110]

my friend says its like: Hard to focus on code but learning and entertainment side by side;

[@_rishi_ranjan]

😂 🤣 🤣

[@jhon3991]

@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.

Plz make a video on move constructor

[@bingolive3240]

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

[@bojansekutkovski9696]

Great example, thanks

[@BasitCeviriler]

How do you not have the default constructor? When I didn't my code have errors.

[@CodeBeauty]

If you need a parameterles constructor but you don't have it, you'll get errors 😊

[@BasitCeviriler]

@@CodeBeauty Isn't it essential?

[@jorgetorres1670]

Thanks.

[@arafathdhroba8897]

you are too good!!

[@erikitter6773]

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 work. Love!)

Ok. Very nice.

[@gower1973]

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

[@oideaijen]

Very well explained! Thanks for the video. Would it be possible to make a video about move constructor? Thanks!

[@jimpapay2895]

I would like to see the difference between copy constructor and assignment operator

[@CodeBeauty]

[@marym9003]

amazing video, thanks saldina

[@Ian-bb7vv]

question: Book 3; book 3 = b1; // this invokes the copy constructor right? thank you for the great video

[@-aditheplatypus-9359]

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;"

[@bardial]

Awesome thanks ❤

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

how to do deep copy in this??@CodeBeauty

[@AbhishekKumar-kk6qs]

Could you pls make some videos on visual studio for developers so that they can be efficient while debugging and development.

[@beremour]

Wonderful

[@SohngShin]

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?

[@lumberjackdreamer6267]

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'm waiting for explain static members and functions please if you don't mind 🙏

[@arthurmbogning9211]

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.

[@HuyTran-ew4yq]

So to prevent the stuff you mentioned above, let use const keyword for the original.

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.

difficult method u used to teach please keep it simple to explain

[@CodeBeauty]

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 👋👋

[@anonymous-nu1rx]

@@CodeBeauty dear , i already know how it work .. but your teaching way , somehow make's me difficult to understand

[@nicholaskomsa1777]

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
