One thing- std::unique_ptr enforces ownership of the object through the fact that it is not copy-constructible or copy-assignable. So, this is perfectly valid code: struct X{}; X* xPtr = new X(); std::unique_ptr uPtr1(xPtr); std::unique_ptr uPtr2(xPtr); It will build and upon execution give double free() error, as the default deleter is invoked twice on xPtr.
I'm so glad you made a video on smart pointers I really needed that and the explanation was really convincing. If possible kindly make a series on advance concepts of C++ which include all these topics like move, move copy constructor, rvalue , lvalue and all. Thanks for the video ♥️
Loved the way how the need was created and how it was explored to get done with these important concepts Di, would be better if the title is aligned also with concepts you and bhaiyya have taught in video!
Actually there is a problem and the problem is this in original unique pointer we can create a unique pointer which points to the array and in your implementation this will be error can you tell me how I can implement this ?

I have query, How move() Called function overloading defined in your uniqueptr class , when you said this function recieves ptr1 as && but how? should not we use ptr1.move() like ptr.reset()? so that it should call user defined move not std::move(). While explaining ->operator , you mentioned we dont have any function but we are using reset as function only ptr1.reset(), if we need to call it as ptr1->reset(), can we do it? one more , how to decide return *res or res and return type would be & or *? Any reference to understand this ..is can explain with diagram would be really helpful. Please prepare video for rvale and lvalue in detail. Thanks alot
The return type does not include the template type T because the return type is not dependent on the template parameter T. The return type is simply a reference to the current uniquePtr object, regardless of the type of object it manages. Correct me if I'm wrong.
I didn't understand the memory leak thing... He deleted the variable 'a' after that 'a' stored in the stack got deleted but still remains in the heap. When he deleted the memory was reduced it came to 757 KB and he said no leak How did this process happen? I just saw memory got reduced...
Exact same question I've. 1. As per your explanation of memory leak, the value in heap memory lies there i.e the pointer variable 'a' pointing to the value stored in heap memory is still there that's why memory leak happens. 2. Deleting pointer variable 'a' stored in stack memory will delete that particular space in stack memory which is occupied by 'a'. 3. But value in heap memory to which a'' was pointing, didn't get deleted as per my understanding. @keertiPurswani : can you please explain?
it seems like you people have explained the same whatever has already written for unique smart pointer right.I appriciate your effort but you can explain the usage of smart pointer, I think you got it now
Hello guys, When I tried to perform the mimicing of UniquePtr, especially the move copy constructor, I encounter the following error. Any help to fix would be great. error: comparison between distinct pointer types ‘UniquePtr*’ and ‘int*’ lacks a cast [-fpermissive] 37 | if(this != &ptr) {
Correction RAII stands for "Resource Acquisition is Initialization" not "in". Its a misnomer and IMHO a terrible name to a very powerful concept in C++
Hi how to delete if we alocate array dyanamic memory Like uniqueptr ptr(new int[10]); Need to handle both single memory o heap and array of memory in heap using delete and delete[] functions
A friendly advice from a developer(and a student too), your content is great but too much unnecessary meme clips in between that distract me a lot. When I am focusing on a particular line and understanding a concept, using my brain, carryminati comes on the screen and rotates his head 5 times, suddenly the line of code is gone and my chain of thoughts regarding the concept is just ruined in a second. Please understand that this is educational video not entertainment video. Thanks.
I came here to see her ex,
and now I'm learning c++ concepts didn't expected that😂
Current husband
Correct
What this Current husband means?😂 she will change it future or what ? no.She is very much commited yo him ♥️
class MoveBF {
private:
Husband* curr;
public:
MoveBF() : curr(nullptr) {}
void move(Boyfriend* before) {
if (before != nullptr) {
curr = before->getHusband();
before->setHusband(nullptr);
}
}
};
What is his name? And where he works?

First time impressed with the way of teaching!
The way you two people presenting is really Fantastic!!!!! Thanks a lot!!!!
He interrupts her when she speaks.
ex boyfriend 💔 but husband 😂😂😂
Best explanation for beginer. For me i still us pointer (as in C), because i like it too much.

Is he using vs code, if leaked yes then
How to get that memory graph 😮

Next video on smart pointers is up! Hope you like it 😇
Will cover other topics as well!!
Please cover other c++ concept as well with your ex bf. His way of explanation is very nice.
New video up! Hope you like it! 😇❤️
You should create a series of this. Loved the approach. Easily understandable.

Just a doubt ,are these high level concepts or used at fresher level coz haven't been taught all these in college?
They teach you in computer architecture in college.
Well Understanding Lot more advance concepts in c++ thank you
the way your husband explained things is really great.... do you guys have any plans for c/c++ bootcamp?
For now, it’s all free. Checkout the new video 😇

Your Videos Are really awesome Sir and Mam Really Appreciable :)
Actually there is a problem and the problem is this in original unique pointer we can create a unique pointer which points to the array and in your implementation this will be error can you tell me how I can implement this ?
Ah you got me, well what you said is right in literal
curious to know of the below call will do the same thing:
ptr.res =nullptr
delete ptr
ptr.reset()
in move copy ctor?
Thanks alot
next level clickbait
Whatever makes people study 🤷🏻♀️
Good videos need such more content related to cpp. Learned a lot of things while watching this video. Thankyou
Saw this video thumbnail in my feed and it's was cringe clickbait for college students. Software engineering has become a joke by these influencers.

Noo C++ is only for doing coding for jobs u want to learn Java for development jobs

May i know why the return value from the copy assignment operator output does not have the template type "T" ?
The return type does not include the template type T because the return type is not dependent on the template parameter T. The return type is simply a reference to the current uniquePtr object, regardless of the type of object it manages. Correct me if I'm wrong.
