I don't know why, but that sofa and the tree swaying in the backyard , bright sunny day, it just all feels awesome and nostalgic..

The best cpp video tutorials I've ever seen, thank you!

So glad you are still doing this mane! Keep up the good work! Document everything you know about C++ its so great to have this playlist at my disposal :-) Thanks as always!

THANK YOU SO MUCH for this video!! You made everything clear

The thing that used to confuse me the most about lamdas was that I didn't understand why there was such a thing as a capture bracket for passing arguments when lambdas also provide the standard way of passing arguments just like ordinary functions do. Then I read somewhere that by using the capture bracket, the variables in the surrounding scope get treated as if they were member variables of the object created by using the lambda. I think this ties in to example you made in the video - when you tried to pass the lambda as an argument to a function that accepted a function pointer as a parameter , it only worked as long as capture bracket wasn't being used. It only passed the functionality defined by the lambda. However, if you want to pass the entire object that gets created by the lambda, together with the variables captured in the brackets, you need to pass it as a function object instead, not just a function pointer. So, in conclusion - arguments passed as parameters get treated just like they would if you were passing them to any function. Variables captured by the brackets become a part of the lambda object.

Wow, this video in combination with the previous one about function pointers was an enlightenment to me! 😄🙏👏 Thank you!

I can’t thank you more. This had puzzled me for more than 6 months. I just felt so relieved and rejuvenated today. Thanks Cherno.

Thanks for the clarity of video! Especially for the second part that includes the functional thing!

This is super awesome. And thank you for inadvertently showing me how to put in a breakpoint in my IDE. Never knew I could do that. :)

Dude your channel is awesome! Your videos are super informative and useful. Keep up the good work :)

Thank you so much.. I was not clear abot Lambas ever after reading so much.. You made it look so simple.

Thanks for this, the learncpp section on this nearly cooked my headmeat.

Thank you for making the video!

Thank you, this was so helpful!!

7:00 "Sure thing now it's not gonna work. we need to convert it and add blah blah one billion obvious other things... aand... here we go!" .___. how you do this man

finally clearing up a topic I tried to avoid as it confused and overwhelmed me when I first saw it.. thanks!

Thanks for uploading :D nice!

honestly a great series for programmer who have past exp , did whole thing (till lambdas)in like 3-4 hrs and understood almost everything .

Top quality tutorial, Thank you.

These are so fun to watch man

Man, you saved my day.

Damn this guy is so good, must feel pretty good knowing that if you interviewed anywhere you can get the job.

Thanks lot. Wonderful Video.

great video very helpful C++ is a powerful programming language but it has so much syntax. for example there are 4 ways to define a lambda function. this is just confusing and makes code unreadable I'm starting to understand why old school programmers prefer plane C. you have structs functions and pointers. with that they can abstract anything they want.

Thank you Cherno! Finally understand it

2:24 This is almost the exact case I was wanting to use this for, funny enough

Start the game engine series soooon please. I'm excited af!

This content ► Amazing explanations

You really know what you're doing. You're so good. Do you have a video about ECS?

u are my favorite, Amazing, u kept it very clear...

awesome , Thank you

You're amazing!

Thanks man

so helpful thanks

thank you

Thank you for explaining that complex topic in a very simple way. A big thanks from India.😊

Thank you!

You should make a video on C++ iterators, dude.

best cpp and one of best programming channel ever

Would be interesting if you highlighted more about why they're preferred to function pointers. They've become almost a standard in many different languages.

I'm reminded of the noun-verb system used on the apollo guidance computer. A lambda variable would sort of be an adverb, then? The best example for when and how to use this that I saw was an example quicksort that took, as a parameter, a comparison function. This allowed the same sort function to be used for any type of data you could think of, so long as you could code a function that told the quicksort which data element was larger, which is slick as hell.

Hey great playlist on c++. Can you make a video on iterators in c++?

One can never have too many function pointer, functor, and lambda videos.

great, helps a lot!

you know the way you teach me is exactly the way i want to be tought

THANKS

Amazing

What makes him a great teacher. 1. Confuses the HELL 2. then explains everything 3. GOD DAMN MY PROFESSORS

The best tutorial on the internet!

Thanks

The level of programming you have to possess to encounter situation in which such mechanics must be used is unfathomable.

Great video. The couch made me laugh.

I would to point out that this subject was very hard for me before using map () in javascript. Basically it is that same thing. And that is way learning new language may help you understand the other

hey.. thanks for all these videos on C++.. Could u also make a video on Functors in C++?

Your the sh** mr cherno, rock on brother

You are the best for c++.

bless yo intelligent, puzzle solving soul

The mutable keyword for lambdas its if you invoke the lambda several times. If you modify lambda copy of parameter - it would affect the next invokation. Thats why you have to explicitly say that its the behavior you want.

Can you please make video explaining the basic differences between function pointer and lamdas?

Could you explain why find_if is any better than writing your own for loop. I know this is a simple example but some of the STL seems a bit superfluous

5:00 When I need that I use it ALL THE TIME.

got to capture them all! [pokemon].

how do I write a function that allows me to pass a lambda into it? do I use template ?

Hey Cherno! What build systems do you use at work?

Do you think lambda's can be substitute for a function which huge function body? I mean..what if the call back function has a huge body and not just a one or two lines of code?

What's the lifetime of the closure though? If you capture something in there you lock yourself in a way because if you free the reference the lambda function can't get to it. If you pass something by value I assume the value is taken from the point the Lambda is generated not when it's called, since otherwise the surrounding code and thus the variable could be deallocated from the stack. But since the lambda can be called after the place it's created, it must be heap so when does it get destroyed? Is that up to us? How do we know if whatever we pass it to is done with it? Lambdas in C++ feel like a memory leak landmine to me with the understanding I have at this moment. - Love them in Swift where I feel I understand the ARC system very well to use them in a neatly handled way memory wise, but here I feel like I could very easily leak memory

do more c++ videos on functional programming

"its pretty simple" every lambda can take inputs within the callback parent function's scope, or take inputs in the declaration scope, using the [] part. and the pointer syntax changes with usage. WHAT

at this point, I can only hear daughter instead of data. tbh. brilliant stuff

make video about constexpr and std::optional

Wait, as i look at the handle of the window behind Cherno, it seems that window opens to outside.

U r love

nice couch you got there.

Missing link to cppreference for lambdas: en.cppreference.com/w/cpp/language/lambda (it was missing in the video description at the moment this comment was posted).

Wow....... thanks a lot ,from egypt .

so, whats the differences between raw function pointer and std::function ?

Why not just only use function pointers? This notation is more confusing and verbose. Could anyone give an example where it would be best using lambdas than function pointers? It seems to me that lamdas are only useful when you want something really simple and only once. Is this the use case?

First of your videos that blew my mind off to another planet. Sorry really you show new syntax there that you haven't told us before... :(

Hi, have question. Is lambda like this [](){/*...*/)(); when it finishes job stays in memory but you can't access it because no pointer is looking at that function, you didnt assigned name or is auto deleted after job is done?

7:12 Can you tell us more about std::function.

Idea for next video: Advanced templates

Does "Capture" thing related to 'Closure' ?

How to pass by const reference in lambdas ? Which might be useful when you pass large objects in lambdas

Apart from Asthetics what is the main advantage of using a lambda over a normal function.

It is like list comprehension concept in python right?

Where is the lambda stored? I am using lambdas as callbacks. If declare a lambda in local scope and plan to call that later will that work?

Function objects. You said in the last video you were going to make a video on function objects.

0:00 Chris? is that you?

you just added "function" and did some magic to make your code work. but forgot to explain what you did. as your "lambda" was having some syntax issue. can you please explain that.

So its kinda like arrow functions in JS ?

Why does using captures with lambdas not work without std::function?

Maybe talk about “Traits” ?

auto lambda = [=](int) {std::cout

why it by reference not value ? and why you dont using --- using namespace std;

Soooooo a callback function

What happens if you capture a stack variable by reference and the lambda is ran after the function which created it terminates and therefore dealocated the captured variable?

hardest video so far

Where's that black line at? :D

So you don't need to specify the return type explicitly for lambdas? What happens if you try to return a different type than what's expected?

Please make a sophisticated course with some sort of company talking about algorithms/data structures, and sell it to us that would be amazing.
