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.
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.
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.
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! 🥺❤
Really good explanation. But sis, wear a proper dress. You don't need to reply me, but change yourself. Everyone Please don't tell 'You came to learn not for anything else'😅😅
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
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
@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.
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
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.
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!
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;"
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
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
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++.
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.

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❤❤

Ohh shit i could not concentrate
Coz of two parameters ?

Always looking at right corner..!!!!
@@crazymemes4080 2 big reasons to watch her videos
Me too 😂😂😂
thanks very much, love your explanations. 👍🏿👍🏿
Lovely channel... it's a value. Thank you very much indeed.....
I love how you explain c++❤ very clearly
I love the content and the person as well
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.
will want to know more about assignment operator as well.
Please make a video on assignment operator!
I dunno, I like the simplicity of just deleting the code that is causing my errors. 😂
my friend says its like: Hard to focus on code but learning and entertainment side by side;
😂 🤣 🤣

love your videos saldina and i'm sure your practical programming course will be amazing as well, i can't wait for it and thanks for the discount
Amazing as always. thanks Saldina
Happy New year Madam, After a long time again I started to watch your videos😊😉
Welcome back, and I also wish you a happy and prosperous 2024. 🥳🥳
can't wait for your practical programming course saldina. i already signed in and i'm sure it will be amazing
Nice explanation of copy constructor!!
Watched 2 times but only focused on two things
ur disgusting
I liove your channel......this is first class of work. Thank you v much .
Ok. Very nice.
Really good explanation. But sis, wear a proper dress. You don't need to reply me, but change yourself. Everyone Please don't tell 'You came to learn not for anything else'😅😅
Bro live and let live. Dont tell others what to do

it's not even that revealing stfu

Thank you, I'm happy that my videos help, and I'm making new videos every week 😄😄
Best C++ tutorials
Thanks! Nice to See you again.
Greetings from Frankfurt/Main
Thanks.
How on the earth you make your every elucidations too simple. I really appreciate it ❤
Thank you for your time
please work hospital manegment system in c++
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
what app you use for screen record and edit your youtube video
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.
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?
Very nice Saldina.
I am from indonesia ...i like learn this is chanell CodeBeauty ...

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?
Thank you, this video explained the topic with great detail compared to my textbook. I look forward to your future video uploads.
have you created any video for assignment operator? Please can you share the link
thank you ....miss CodeBeauty Godbless you miss...
i really can see ++
Plz make a video on move constructor
cant wait for your course saldina, I love your videos, they are the best
Thank you for your videos. It helps a lot!
do you have any videos on object compositions?
Fantastic and to the point. Thank you!
U're amazing...
U just make coding easy🥺❤️
Thank you this video. Great to see C++ thriving. Please ignore the stupid and humiliating comments. Looking forward for more content.
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;"
Thank you for your work.
Love!)
Good explained! Do you have video or maybe you are going to prepare explanation of move constructors?
you are too good!!
distracting more than learning experience 😶
😻👍
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
I 💕💕 your videos on c++
Could you pls make some videos on visual studio for developers so that they can be efficient while debugging and development.
Tricky, yet simple. Only because of your explanations. 💗💗
Thanks!
Thank you 🥰❤️
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
Your explanation is marvelous, as a beginner, I have a better knowledge about copy constructor. Thanks and please keep going
🥰❤️

Can you pls make a video about move constructor and move semantics its really hard topic for me to understand
very good video , but it's hard to focus on the code when i see u
I'm waiting for explain static members and functions please if you don't mind 🙏
Thanks!
Thanks 🥰❤️
I usually watch tutorial videos in 2x. Not this one though ;)
it was an incredible section thank you very well for your efforts you are the best teacher that I ever seen
Very well explained! Thanks for the video. Would it be possible to make a video about move constructor? Thanks!
Amazing Explanation!!
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++.
I gave up programming in c++ years ago ... You gave me hope to rethink my decision ....
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.
distraction...
you're easily distracted
😻😻😻
i really love your videos! thank you for the content : D
completed the whole playlist. Best way of explaining oops.
how to do deep copy in this??@CodeBeauty
your channel best on youtube related to programming.

So to prevent the stuff you mentioned above, let use const keyword for the original.
Cool, when unit testing and ndk? 👻, pls🙏
Error exception! Code not found! ;-)
Great example, thanks
amazing video, thanks saldina
