Lambda expressions in modern C++ (in depth step by step tutorial)
ฝัง
- เผยแพร่เมื่อ 30 มิ.ย. 2024
- A lambda is an unnamed function that is used for short snippets of code that cannot be reused and are not worth naming.
It makes the code cleaner, easier to read, and lambdas are also fast to execute.
Lambdas are available in C++ version 11 and above.
In this step by step in depth tutorial I'll teach you the most important things about lambda expressions, and also share some tips and tricks, and if you want to practice and see more examples of lambda expressions in modern C++, download free E-Book below.

I have asked for this topic like 7 months back and now got it. Thank you.
The beauty about your videos is, I always watch them to learn something I initially intended to but, I always end up learning some extra things. Thanks for that. You're awesome
You are the best C++ Lecturer in TH-cam. You explain the topic with the example, including all other special features of C++. Like in this "lambda function" example, you also included 'Standard Template Library' vector and algorithm. That really connects with the real coding problems and uses of all other important features of C++.
Thank you for teaching us, all these things :)
Thanks a lot :)
Today, I first learned lambda function of C++.
I learned from the best. (Whitney's one of my favorite songs)!!
Im learning c++ on udemy and I always come to your videos for second help. you always have a great way if explaining these concepts . Thank you for posting these videos. for real!
Perfect timing! We are covering Delegates and Lambdas this week in my C# course.
I was struggling with this topic since yesterday.. it's all clear to me now! Glad I came across your video..Thank you CodeBeauty, Keep making such videos!
The best explanation, I need this video a lot, thank you CodeBeauty!!❤
this video is so easy to understand, love it
I love the way you teach the lesson, and in general your lessos are very helpful. Thank you very much.
Hi, I'm from Brazil and a developer beginner but with much years at development using C++; Your channel is my favorite font to learning c++ and english; This is terrific. 🚀🚀
You are so talented for teaching, the best teacher ever!
Thank you. Best C++ lambda introduction I have seen thus far.
Saldina you are the best as always ❤❤❤
15:51 You can change the value (only in lambda function) by typing "mutable" between the circle and curly brackets.
This way you don't have to change the variable in bigger scope by passing with reference.
Disscussed in Cherno's video on lambdas th-cam.com/video/mWgmBBz0y8c/w-d-xo.html
yea i should have gone to cherno to learn about lambdas, cause she defined only function pointers in signatures.
This video is awesome! Thank you I have a better understanding now. I am a struggling student and your videos help out greatly
So useful and simple.. thank u Saldina 🌷
Exactly what I was looking for. Best channel for C++
First time it's ever really made sense to me. Thanks!
These books are amazing, thanks for sharing free resources with us Saldina ❤️
Glad u like em 😃😃
perfect tutor and perfect lesson. Thank you!
Great description!Thank you!
Thanks for this lesson. I really need to learn this for our management project. Great teaching as always❤
You are so welcome 🥰
I finally understood that! Thanks!
love your videos
Never had a full grasp of lambdas until I watched this video! Thanks beautiful lady 🙂
Happy to help! 🥰
Nice job madam. Thank you so much.🤩🤩🤩❤️❤️❤️
The best explanation of Lammdas I have seen, not filled with computer science geek mumbo jumbo those guys love to spew.
I have a biomedical engineering master degree, and I decided to learn C++ in the best possible way.
Thank you so much for existing.
You cleared my basics very well thank you ..!
@CodeBeauty You're really a great teacher. Thank you so much for the classes. Really helpful. Please keep on making videos. God bless you!
Thanks aloooooooooooot for explaination , quiet and concentrated
I hope you go forward

Thanks, cool and simple explanation
wow i never comment on videos but this simple explanation honestly blew my mind! thank you so much
Thank you! it was quite helpful!
I love your tutorials.😍 feedback: can yo please zoom in the code area? You can remove the folder and class structure views in VS. Thanks 😊 🙏 🤗
3rd~!
All of your videos are extremely important for the beginners like me. I learned a lot from these. Only one catch, beginners like me need a bit more practice problems and as well as a bit more theoretical explanation. Would you recommend some book on c++ which is very close to your lecture spirit or which you find suitable for learning cpp with practicing more? I will be grateful to you for your kind act.
Des explications claires et simples ! Je vous remercie beaucoup
de rien ☺️🥰
lambda confused me for almost 1 month and i always tried to not read thos code written by lambda untill i watched your video. Thanks so much.
I'm so happy that it helped you ☺️ 🤗
you explained lambdas so simply and beutifully
Good video. Learned a lot. Thank you❤.
thank you! :)
Thanks, Great Teaching..
Good explanation, thanks.
exelent , learn match more then the course (expensive and to my lang) ! great thanks :)
Hi, I am trying to learn C++ and did watch your learn c++ in 10h FULL COURSE video for beginners and I would like to start with lambda expressions next, since I need it for an assignment for next week(yes I know, lucky me you uploaded this just today :D). You have a lot of videos about different topics regarding C++, stuff that wasn't in your 10h C++ video, so I was curious if I need to watch any other videos before learning about Lambda expressions. It would mean a lot if you could make a playlist which does include all your videos about C++ in the intended order from easiest(beginner) to difficult(advanced). That would mean so much for people like me who want to know it all!!! :)
Thank you for an amazing explanation
🥰
This book deserves more than a thank you! Really useful!!!
🤗💓💓
@@CodeBeauty❤❤❤❤❤❤❤❤
you are briliant thanks.
Hi codebeuty love your videos thank you very much! Just a tip im not sure if it works in vscode, but in notepad++ you can highlight and hit cntrl+k to comment out all of that code. You can uncomment it by highlighing and cntrl+shift+k. Also you can overwrite a line by highlighting it and using paste directly on it with cntrl+v. If you want to select multiple lines with the cursor to tab several lines etc you can hold shift alt and left click down each line you want to have a multicursor really handy. :)
Very well explained
osm explanation and detailed info. good job thank you
Excellent content!
Isn't it a coincidence? I just started using lambdas in C++. Thanks;)
awesome! thank you!
Thank you for this very informative and beautiful video, CodeBeauty
Thanks for the content
this is a great tutorial
thanku it was really useful.
saldinaaaaaaaaaaaaaaaaaaa! you are a great teacher. absolutely you are the best!!!!! thanks a lot!!!!!!!
Damn that's a handy tool to have! Looks like Lambda expressions can get pretty complex pretty quick though.
I like your pronunciation of "parameter". :)
Well I love to see more topics about morden c++ like that
Thank you from Beirut
Hi Saldina! Do u have any video about encryption/decryption strings in c++?
Great video BTW 😁
Thank you...!
Just out of curiosity, what is the difference between the variables in the [ ] capture clause and the () parameters?
And great job with the video, top notch stuff! :)
thank you
7:02 - This kind of structures (classes) with overloaded operator() are called Functors.
So pretty much just like Python lambdas, they're used as "throwaway" functions. Thanks for the practical example.
Great, thank you CodeBeauty
You are the best lady you should know that.
Thank you
much helpful :)
Great contents
❤❤
C++ Builder?! Hi, colleague! Шt's nice to unexpectedly meet such a rare specimen who is still working with the С++ Builder. But I still use CB2007 (C++99) due to a lot of strange things in many last versions... The very last release looks more acceptable so perhaps it's time to move forward... Thank you for video.
Amazing..thx
Thank you too!
Dear mam u r brilliant
I am watching all the vides , thanks a lot about your programming productions, i would like to say that
one of my important problem is still unsolved on your side.
and that one is (MY REFUGEE REQUEST AND GETTING ME OUT OF AFGHANISTAN).
again thanks a lot,
your SUBSCRIBER Nasrullah Kuhzad from Afghanistan.
Hey Saldina, you dont have by any chance video explaining iterators and object functions? Could really use your help on that..
thank you Saldina for the perfect explination
you're welcome 🤗🥰
@@CodeBeauty❤❤❤❤❤❤❤❤❤❤❤❤
Always nice video
Hi Saldina!
Is it better than writing code in the body of a simple for loop? This is what I never understood about sheep.
Thanks for the reply!
Thanks.
not sure if someone mentioned this ..
the code
[](int x) {
if (x % 2 ) == 0 )
..
else
..
can be stored in a variable and then passed it to for_each function like this:
auto func = [] (int x) { ... };
std::for_each(v.begin(), v.end(), func);
to make it clean
