Pointer concept isn't hard. Syntax is just awkward and confusing imo.

if you mess it up it can be very dangerous too. One of the Syntaxes you have to understand before you try around. Thanks god c++ has smartpointers aswell.

Dude you're so good at explaining stuff. I was trying to understand function pointers for so long and all it took was this video. Also really good job on the threading video. Keep it up!

Your videos are absolutly amazing! You mix it up! Most youtubers just make you stare at a console through the whole course, and they only use their cursor to explain things. This playlist is well put together and well worth my time. Keep up the good work

Hey dude, just wanted to let you know you are my go to for getting foundations of principles. You've helped me out several times. Thanks so much!

By far the best videos on C++. Thanks man! You just taught me overnight what my professor couldn't in 7 weeks.

A+++++ content! I've been wanting to learn more about function pointers.

Found your c++ series now. To learn C++ and dive in quickly your videos are absolute great!

This is the greatest coding tutorial series iIve ever seen. If only somebody as talented and knowledgeable about the subject would make similar styled tutorials for other coding languages, the world would be a much better place

Your videos are amaizing, I was struggling with pointers and function pointers on my faculty projects and your tutorials made my life easier. Thanks and keep doing the good work.

Thank you so much!! I was revising cpp and I got stuck here. This really helped me a bunch. Definitely subscribing!

I think what makes you so much better than everyone else is the fact that you give examples of where you would actually use all the things you teach in code.

Another nice use-case of function pointers could be system calls in OS development. You can talk about how the operating system stores an array of function pointer corresponding to each system call and that helps calling functions simply by indexing in that array.

Very few people do such an excellent job at this. Thank you Cherno! :)

The simple explaination makes it very helpful! :) Thank you for this series and keep going like you do.

This is like when you are half way through the semester and half the class dropped out or changed major.

Dude. Your explanations are saving my life right now!

Man, it's awesome, thank you so much for these lessons ♥

Im so in love with u that u continue this series

i love that you give a real useful example! ive seen bucky's videos and he never does this. he just tells you the idea and i guess assumes you know when to apply it. great job!

Thanks for making these videos, they really help a lot!

Man, that is absolutely crazy! Honestly, the more i learn about C++ the more i want to learn about the language, it's like you're fighting a Hydra, you cut one head but two grow as a replacement. I know these things aren't actually easy to get, and since there are like an infinite ammount of things you can do with this language, sometimes it just makes the programmer's life harder. But i think that this just shows that C++ is all about giving control to the programmer to do basically anything he wants to do, which i find it to be fascinating in it's own way. I'm aware that you won't read this comment since this video has been out for a long time, but i seriously am grateful you made this huge ass playlist bro! It's really really helping me to learn this language Thanks bro!

best c++ tutorials, thanks man

Brilliant content. I can't thank you enough, Cherno!

I like your videos, sometimes I just need a quick look into a subject and don't have the time to read the technical reference pages. So I just crank your videos double speed and blast my brain. :D thnx

Thank you Cherno for this super fantastic explanation!

Great content! I was trying to write a homework and couldn't understand what I was doing wrong. after this video I could fix it immediately. VERY HELPFUL THANK YOU

A function and a pointer to the function are different types. When assign a function to a variable, func converts itself to a pointer implicitly, just as you mentioned. On the other hand, we can use a ptr to a func to "interact" with "operator ()" just as func itself, just because the "()" is overloaded implicitly, I guess. Actually, a function is able to be "quoted" by reference with the original type rather than a pointer. But when you want to store several functions to a array to do a batch call, the pointers are stored.

Love your videos! Helping me a lot with my university stuff!

Awesome explanation. I did search a lot but couldn't understand. But now all my doubts are clear after watching this video. Great content.

I learned a similar thing in GameMaker and used for Finite State Machine, where state function is assigned to a variable that is called each game frame.

The best C++ explanations EVER! Thanks!

Such a great explanation with examples.

excellent video. well explained. function pointers seem useful but the way I've been exposed to them so far only highlights the confusion!

This brought back memories... I remember back in the early 2000 when I added a console to my game engine and hooked up function pointers to strings to be able to call those functions from the console :P

Passing functions is super useful sometimes. It's a concept I first saw using JavaScript. It's really cool that you can do it in C++ (for a while) now.

Keep up the good work. KZread need experience coders like you.

finally i understand why there is need for function pointers!! thank you .

That explanation at 1:04 just clicked in my head and I didn’t even watch the rest of the video. Thanks brotha 🙏🏾

Function pointers were the precursors to OO. On rare occasion, I still use function pointers ( for dll support) , but really, you should avoid them when they are not necessary, not just because of the obtuse syntax, but because they are too loose - which means intractable bugs. I have seen people essentially reinvent c++ using #define and function pointers. I'm sure they thought it was really clever, but they were the only people willing to maintain the code. As soon as they leave the project, the first thing that happens is others toss their unmaintainable garbage code into the bit bucket and start over.

I just realized this is how callback function works. Amazing!

Good work ! I need this video , it's awesome !

Bro you're a fantastic teacher! thanks a lot!

Thanks for demystifying subject

with this we can implement map(), reduce(), filter() functions as well.

Function pointers allow us to use the concept of higher order function map, if the map function is too complex, then lambda functions won't be readable. So I think that function pointers are still an important part of C++.

Every time I want to know something about modern c++, I come here. Good job Cherno!

"Gentle introduction" lol 😆

That helped me so much in writing my own game engine with glut window and opengl

Great content. Thank you cherno

Thank you so much for showing new tricks.

Thank you for cool vids. Plz don't stop.

Thank you so much !! Great Teacher !!

Great as usual 🔥

Amazing video! Helped me understand better

In C# i use Action for function pointers. Function pointers are great for Publish/Subscription type of projects.

Probably the best c++ tutor on youtube

i personally love function pointers. I regulary store them in hashmaps , to call a similar, but different funktion every time. Like when i create elements of some sort, but the functions are only similiar in theory, but the execution is different, even if the result is the same. And at this point, i create a HashMap, calling the functions by keyword, with needed parameters. Thats so cool, it really helps me keep my functions organized, and i can add another element to the Map easily at any point For example when i want to parse Network data from another program, or via Rest APIs

I respect you dude

Excellent Video's. Thank you. It would be very helpful if you could have an few famous problems related to the topic and maybe a solution video .

mate i fucking love your series

Great video, again !!! Thanks !!!!

OMG! did i just learnt lamda and function pointer in 10 minutes... awesome!

Thanks for your video!

Thank you!! You just saved me and my assignment from the due date

I always enjoy your video.

Really good tutorial. Thx from China ❤

finally a channel whose videos i dont have to watch at 1.5x or 2x

I hope that you'll talk about method pointers in the next video and how you can use them without the standard library.

Excellent vid.

Dude, you make me feel more exited about computer science

Great job!

This is very handy matter in C++. I can pass a pointer as a parameter, pointer to function which I want to be in charge of handling values. :D

Clean cut

Start a data structure series please, greetings from Texas

The name says it all. It points towards a function instead of a variable.

I have always struggled with pointers but this video actually turned on a lightbulb for me XD. I know function pointers are different but the "pointer theory" if you will makes much more sense now!

I know it's a bit late, but GODDAMN THAT HAIRCUT MAN!!!!! Everyone looks good with a fade and part

This blow my mind!!

Really Fantastic Explanationss...Great............PLEASE DO Post Videos Related to Design PAtterns and DATA Structure.

He's so cute, makes learning C++ that much better lol.

thank you!!

Cool mister. A good explanation.

I just find this so cool

I've been working with UE4 and dispatchers seem to work based on function pointers, but I was never sure what a function pointer _was_ or how it was _written_ because UE code is so....'nebulous' isn't the right word, it's just kinda hard to track stuff down is all. And this video got me caught up. A+ stuff right here.

Man have been coding for a while, even that passing function inside another function using function pointer is sort of a overkill but yeah that's a way and can be used. I am majorly from a C background and mostly in my code we have seen the function pointer array but this was next level, the lambda is not known to me much, will go through and understand it.

you should do a video about using variadic templates function pointers, its a really cool topic.

this lesson which involves some many technical things such us auto, vector, typedef, function pointer, reference, even iterator inside

C++ Callbacks! Nice

very good explanation

really awesome

@TheChernoProject I've never seen that kind of for loop! I kinda understand what it does: for (every index in : this array) do this; I'd like to see what other ways that could be used! Could you do a short video, or dedicate part of a video to explaining that. If you've already done that, can you show me where to look? :) Thanks for the vids, they're so helpful

So, like nested functions, essentially? very cool

many thanks

so cool!

Great C++ videos! Much appreciated. Is that an XPS 13 your using?

this is the best

.... in the future... Just kidding. I find your series extremely useful.
