"By no means is this going to be the only video I make on templates" - The Cherno 2017

For all the novices out there, I think there's one important thing he overlooked regarding using templates. With templates, you must either write AND use them inside a SINGLE source (cpp) file, OR you must write them ENTIRELY inside a header file. Unlike a regular function or class, you can NOT declare them inside a header file and then define them inside a source file. The linker won't be able to link the templates if you do.

I love this series. Motivated me to learn c++ and just got my first job as a software engineer. Keep it up!!!

I know he’s an expert in C++ because he can talk about single concept for ~20 min, where every second counts 👍

Simply, the best C++ lessons in existence.

Template = compile time polymorphism I don't like overuse of template, debugging is a nightmare. I have seen this horror myself.

Another reason you shouldn't want to go too crazy with templates is compilation times. As cherno said, you're basically having the compiler write code for you. If you start having your compiler write a ton of code for you, then be prepared to wait a bit longer for your program to compile.

I love your series! I was having trouble in my C++ class and my TA suggested I should watch your videos. It has helped immensely

Really appreciate your series.. The way you explain things is so simple and effective

You sir are amazing..we need more from you. Please do not stop making videos

This is the first video i've seen from this channel and i can't stop smiling at how easy he has explained templates! i'm so excited i finally get it! well done mate. great video. subbed

Great work as always! Your vids are on a totally different level! :D

This is a magical! the ease you explained one of most confusing and complicated topic is brilliant. pls keep going

These videos are amazing. I spent a whole day trying to figure out how to create an array of an unknown size in a class, only to give up and move on. I see now how it can be possible. So very well explained. This series is getting me though my college courses. Thank you for sharing your knowledge.

I was trying to understand this Templates for such long time, and only now i understand thank you very much !

The content of this series very apt and rich. I am recommending this to my friends. Thank you for doing this.

Thanks for this series. I have learned a lot from you!

Your videos on c++ are AMAZING! Everything that my professor confused me on was ironed out in these 10-20 min videos. Thank you so much🥹

Best video about templates (Your series are awesome)

woow amazing! I love how you actually put it into code and shoe us how its actually running. My instructor would only show it on whiteboard and I could not understand it but, seeing it in code helps so much!

You make learning C++ so easy and entertaining Keep it up!

Thank you very much for the tutorials, they are helping me immensely with my Electrical Engineering Studies. This is the 2nd semester I have sourced your tutorials during cram sessions and they have helped. :-D

I love these video like documentations of individuals aspects of C++. Please keep making these, I love them.

this is probably the best tutorial i have watched, very intuitive. Awsome work brother.

Excellent, I think this will help me a lot in what i'm currently developing! Thanks so much for your great tuition :)

Wow, I think this was the cleanest sum of templates I have ever seen. Thanks a lot!

Amazing videos, just started watching the channel. I plan to watch every posted video. Keep it up!

Easily the best C++ resource on KZfaq, thanks man!

Fantastic class. The basics of templates got so easy now.

This is one of the best videos of this series!

Clear, concise and straight to the point.

best tutorials ever please make more since I can't find anywhere else such detailed and advanced information and this information is what can make me a good programer

Sometimes when i watch these videos, I replay that mind blown video in my head.

Thanks for the intro for templates. Especially what really happened under the hood. Looking forward to see more of these coming!

Your videos are the best. Never stop making 'em.

Really great video, thank you! Explained with such clarity.

Very simple and clear. I'm glad that I found your channel. Thanks!

IMPRESSIVE explanation. Very very VERY clear. Thank you.

best explanation of templates I have ever seen. thanks cherno!

your delivery is really superb sir. Didn't see anyone like you.

The thing I loved back when I started with C++ and learnt about templates (although the syntax can understandably look like drunk talk to people) was the fact that this is NOT some dynamic thing based on some shared base object the entire language uses but still enables you to create equally or more flexible code. By having the compiler generate the needed code for each type you use your templates with you basically add no extra runtime cost. That was awesome to young me. Another great side effect of how templates work and the fact that the template doesn't actually "exist as code" is that you can have a huge library of templates and it would not actually grow your binary a crazy amount unless you use them all. If it instead was a hughe library of "actual code" your binary would contain them all even if you only used a few of them.

Awsome video! I love the chill vibe and your voice is great... =)

What a much better introduction to templates than just explaining how vector foo or something.

you make it so easy to understand! Please continue with more c++ vids. thank you :)

i am sitting at work doing code reviews and watching your videos lmao you are a lifesaver

This class stuff got me low key excited

THIS IS THE BEST VIDEO TO EXPLAIN TEMPLATES. You just earned a subsciber.

A VERY clear explanation of templates. I will point newbies to your channel.

As a matter of fact, the templates system is turing complete - that means you can actually implement ANY computer program using templates (and that program will run at compile time). Great video !

"This can get really crazy, really quickly" is my favourite quote here.

Dude this video is perfect for some one not understanding templates! :D

Best C++ series I could find on the internet

Love ya 😍😍😍 and of course your series. Every sec worth a treasure!!!

You're genius! Thanks for this video!

best source of learning cpp ever. thanks man!

Thanks for making this video, I finally have an idea on how this template thing works

That's the best explination I came across so far , thank you

Nice to see that you got straight to the point, where I was able to understand templates after having 90 minutes of programming lecture in the university without understanding a single thing :D

That was a fantastic explanation. thank you very much sir

Really the best video that explains templates. Thank you alot.

Really loved this video...even stackoverflow kneeled down before you... thanks again.

the example used by you is really good.

Was waiting for this. Please make more template videos soon :D

Why is it that nobody else seems to be able to explain c++ templates so clearly? I probably spent half a day struggling with this, then came upon this video and it was immediately clear. And even if I knew nothing about templates before seeing this, I think I still would have understood just as clearly. Thanks!

Nice sofa. Looks very comfy.

That is brilliant mate. Thanks!

Thank you, it is wonderful explanation!

I just learned more in 18 minutes than reading the same thing over and over again in my textbook for over an hour. Thanks man!

Fantasitc way of explaing this, thank you

Was waiting for a template video !

great examples, Thank you

wow.... I'm sooo glad I clicked on this video! thank you so much for the clear explanation!

Man, you got me with this nice tutorial, i subscribed! Thanks a lot.

Great job. Good explaination.

You explain things better than some highly rated C++ lecturers on Udemy.

WOW I just understood a load of stuff I didn't before... Thx Cherno. Best tutorials ever...

Now I understand. A very clear explanation - Thank-you.

you won't find a better like to dislike ratio for coding tutorial than your channel, your tutorials are awesome, keep going!

You did a fantastic job explaining things as I'm currently studying C++20 and later C++23 with ESP32 (even though the library is C). My experienced friend with C++ experience elsewhere suggests that I should try a template for class objects, which is why I'm watching this.

dude, you are awesome. brilliant explanation and simple, keep up the good work. (Y)

that was so amazing dude thamk you so much

This is the best C++ series I've seen so far.

your really make it look so easy ! thank you

Finally, I got how this weird C++ code in unreal engine works thanks man you made my day!!

amazing, very well explained

Wow. C++ is so powerful. Lots of possibilities!

*My takeaways:* 1. Problem with function overloading 2:02 2. Function template 4:01 3. Class template (variable) 10:06 4. Class template (data type and variable) 12:16 5. Where we may use template 16:10

Really great videos, thank you sir

Dude, please don't let this C++ series go for OpenGL, Hope to see them both continue. Keep up the great work!

I wouldn't have started learning C++ if it was not for your videos. I watched starting 18-20 vids then shifted to books because I really needed to clear few concepts. Now I understand a little bit better than past and m back !!

Hey Cherno, I love your work. Continue like this. I want to ask you if you could make a series of networking, from the basics. Like sockets, client server. Thank you for your work.

Solid video again. Would like to see one about your own implementation of enable_if and some usages!

Would like to see a video regarding template metaprogramming. That stuff is mind bending.

Hey Cherno ! Love your videos ! Really well done, technical enough to be really usefull and really help out but also very well simplified ! you made a video serie on on OpenGL, I was wondering if you are planning on ever doing something on OpenCL and or Cuda, thoses languages are awesome, but coding examples in thoses are ussually pretty rare. keep up the good work !

Thank you, great video!

as someone coming who is a noob and from a high level script language like python small bits like this at 6:15 are super helpful to clear the air

I love the fact that the first time that he said the template definition i didn't understand, but then he wrote the code and when he repeated the definition i did understand what it meant. Thanks for the videos

My man cherno helped me once again

the way that u explain it bro just u r the G.O.A.T. in this game!

Please make more videos ! I enjoy your videos.
