"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.

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.

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

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

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

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

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

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

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!

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

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

Best video about templates (Your series are awesome)

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

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

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

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🥹

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

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

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

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

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

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

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

This is one of the best videos of this series!

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

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

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

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 !

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

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.

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

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

Best C++ series I could find on the internet

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

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

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

IMPRESSIVE explanation. Very very VERY clear. Thank you.

This class stuff got me low key excited

You're genius! Thanks for this video!

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

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

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

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

Clear, concise and straight to the point.

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

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

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

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

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

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

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

That is brilliant mate. Thanks!

best source of learning cpp ever. thanks man!

that was so amazing dude thamk you so much

Great job. Good explaination.

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

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

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

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

amazing, very well explained

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

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

Cherno is an industry man that can also teach better than most college professors.

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

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

your really make it look so easy ! thank you

Thank you, it is wonderful explanation!

the example used by you is really good.

Was waiting for a template video !

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

Nice sofa. Looks very comfy.

great examples, Thank you

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

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.

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

Still rockin it, keep goin man

Great c++ tutorials!

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!

awesome tutorial thank you!

thank you cherno. great explanation;

Hey cherno ! love the series keep up the good work ! any chance you will cover Threads in the future ? thatd be awesome ! i worked a lot with them in Java but they seem wildly different in C++ for the syntax and handling of them.

Thank you, great video!

Fantasitc way of explaing this, thank you

Excellent tutorial

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

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

Really great videos, thank you sir

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!

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 !

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

this guy is sooo amazing!!

Please make more videos ! I enjoy your videos.

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

Thanks again!

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