I know right!

[@TheCherno]

Glad you're enjoying it! It feels much better to be producing higher quality content, much more satisfying :)

[@NexGenSlayer]

You should market your videos through blogs and other resources to get more views because everyone is right when they say you have probably the best (highest quality) programming tutorials on KZbin

"There are very little rules in C++" ...Until you start pushing your code to the company repo.

[@47Mortuus]

Sorry, didn't know your company is a part of C++

[@patricktorgerson5810]

I've been programming as a hobby for 5 years now and know all of this stuff, but I still find it entertaining to watch. I really wish you were making these when I was first starting out, you do a very good job of explaining, and go into thing that most people leave out. Nice job, keep it up!

[@lewisb8634]

Patrick Torgerson Same here, but for about 2.5 years. I know everything that has been covered so far, and I imagine I'll know *most* of what is taught here (there were some topics in the introduction video I know I'm not solid on), but I'm watching every minute to support Cherno and pick up any fine details and points that I will have inevitably missed :)

[@MsJavaWolf]

I program for 12 years, I watch those videos because sometimes new employees ask me about programming concepts, I want to improve my teaching skills.

[@abbysabbydoo24]

Can you help me in my computer programming class then 😅

[@davidthorvaldsen8903]

Dude.. What a gold mine of a KZbin series! Best videos I've watched on here for a while now. I have a C++ recruitment test in a few days and felt quite lost to be honest, but now I'm finally understanding what's happening without just writing some code and pressing "build & run" (like I did with an IDE before at uni without really knowing what was happening behind the scenes)! Thank you so much my Aussie friend :) Love from Norway

[@Hellbending]

2024 and learning c++ and this video playlist still pops up in OTHER KZbinRS vids saying things like “Go watch this cos it’s amazing!” And they aren’t wrong, this is gold mate, bless ya haha ❤

[@mixchief]

No one ever reached my brain as efficiently as this guy. In a way, he really knows how to allocate memory registers in my brain, so I can remember and actually use the information stored. This is surreal.

[@viatori5566]

It is night and day following along with these videos after taking a c programming class.

[@tannerbeez]

Yan, I love the production value of this series, it really makes you look professional. Great job man, love the series

[@rdwells]

One minor addition: If you want a bool variable to print as "true" or "false", just precede it with the std::boolalpha I/O manipulator: bool b = true; std::cout

[@manfromtheoutside7227]

You have a differnt way to teach, it make learning cpp possible for me. Peace

[@muhammadhaseebmujtaba5960]

[@HassanSani]

You just turned a whole CS semester into an ABC kindergartner class, Thank You

[@_Hadda]

This is by far the best c++ series on you tube, great job! Subscribed and notification bell on, looking forward to more!

[@jamesmnguyen]

This video was great. It covered the basics as well as common pitfalls like compiler specific sizes.

[@dorillo765]

Dude you're making c++ possible to understand. Thank you!

[@mytech6779]

Should note for those watching. An unsigned int is generally reserved for special situations where the sign would cause specific error problems, not just because you are on your last bit. For general math if you are on your last bit best practice is to use a "wider" type such as a long or float. This is to improve future maintainability and avoid weird bugs, of course there are some exceptions to the rule but they are advanced cases such as memory limited micro-controllers where single bytes really matter or very advanced high performance bare metal coding where the hardware structure is considered in data transfer and physical location.(where microsecond lags matter or the calculation takes a 10 000 core machine several months(while using nearly half of a megawatt) 5cm of wire is about a cpu cycle)

[@GfastGao]

not just because you are on your last bit => Got it.

[@cweasegaming2692]

These tutorials are really giving me a head start before I go back to school in September. Thank you for this! I've also really wanted to switch over to Unreal from unity for a while now and this is the C++ content I've been searching for!

[@jagdishannepu7179]

I am glad I found your channel... I wish any of my professors were into explaining us so patiently and selflessly. Thankyou brother!

[@PROTOTYPZ]

Even after taking a few programming classes there's still a plethora of information here. Thank you very much Cherno for going into the little things.

[@vedantchaudhari7123]

damn! every freaking time i look up your name the freaking chernobyl disaster comes up scary af

[@SantiRodriguezRuiz]

"Cherno" means "black" (color) in Slavic languages. Actually chernobyl (чернобыль) is the name of Artemisia vulgaris in Russian, which is a common plant (not nuclear, but a weed) in Europe.

[@DheerajAeshdj]

@@SantiRodriguezRuiz thanks wiki

[@amrojjeh]

I have never seen programming explained like this. you did a perfect job as teaching.

[@general9064]

This Cherno c++ series is all I wanted to understand about c++. Cannot thank you enough. The clarity in your explanation is exceptional.

[@Chevifier]

I love how this was five years ago and the production feel like this year. Just decided to learn c++

[@Asiamirza427]

Yup... just wow

[@Voskos]

how is this going

[@gameplayyt504]

This guy does make learning fun. Especially with the background music. And tbh i can't watch other youtubers than this one. Keep up the good work!

[@theturtlepwn]

You are an amazing teacher! I'm an experienced programmer, but I never formally learn C++, and even though I already know what variables are, I still feel like I learned something from this video.

[@TheHuggableEmpire]

It's definitely the "only difference is size" part that gave that vibe 😁😁

[@krec348]

Absolutely fantastic! You explain it so well, please.. PLEASE keep doing them and a big thanks!

[@drulli1]

Awesome way of explaining C++. I have seen quite many other tutorial, jumping directly into details. Showing first the big picture and the concepts creates lots basic understanding. Quite an eye opener, very interesting. Thanks a lot!

[@jasonzhang5755]

Need to say that this C++ series is amazing. Love it. Please keep doing it. Many thanks!

[@w3w3w3]

Got this series linked on a subreddit. Best thing ever. Thanks;

[@jp-cy1hi]

Excellent explanation of what is happening at the low levels of the computers operation. This is commonly left out of other tutorials but I feel it is essential knowledge to have in order to really know what you are doing when writing code. Thanks for the great videos!

[@codyverdes3289]

Thanks so much for making these videos. They're insanely helpful.

[@MarshmallowMadnesss]

[@timetolearn5523]

Wow! I think it is the best video that I have ever seen about variables, very well explained. Thanks for your videos!

[@Sturm14]

First of all you do this really good, keep it up. @9:22 i want to add this, 5.5 there is a double, but implicitly cast back to a float, since we assign it to a float.

[@keven444]

Really love the new format of these videos!

[@musikk7521]

This is truly a great series, the combination of visual studios view, and the facetime while explaining certain things is a helpfull change from other tutorials ive seen. Are you planning on making a video for how to understand large codebases? I started a new job recently and was overwhelmed by the size and complexity of the code, accross headers and modules. Anyways, thanks for the great videos :)

[@DailyGamingLive]

I have watched the first 21 videos and am rewatching from this video for the second time after also reading on a website and using an app with practice code and watching it a second time I am following along much better and even getting ahead this time! Your videos are great and I will likely be rewatching this video again later on to solidify my knowledge a bit more! Great series!

[@jairambhardwaj716]

You gave me the utmost clarity of variable ❤🙏

[@ZeinFakhreddine]

This is a really good series nice job. I'm excited for the videos on pointers and references those things always confused me when trying to program in C++

[@MrAlbinopapa]

Man I remember those days...because they were only two years ago. Don't worry man, pointers will click eventually. I think of them as directions to my data. Your boss asks you for some report, where is it? In the filing cabinet in the third drawer. The pointer is the address or location of my data, in this case the third drawer of the filing cabinet. With pointers, the variable that stores a pointer can be changed to point to anything of the same type ( technically anything if casted ). When you remove the report and hand it to your boss, the location of that data changes. References are basically restricted pointers. You can't reassign a reference once it's initialized, but you can change the data that it refers to. So using our scenario above with the report, the reference to the report will always refer to the report or something like a reference to the filing cabinet with all those reports. The reports inside can be changed or moved around, but the reference to the filing cabinet will always point/refer to the filing cabinet. I'm sure TheCherno will explain this much better than I have, so just wait for him if this has been clear as mud.

[@TheCherno]

Yep, I'm going to make sure that video is absolutely perfect before I put it up

[@wz5445]

[@amp2amp800]

I'm 64 next month been a pro C++ programmer since it was invented, and C before that. I just LOVE the way you can lie through your teeth to get to the central truth, and sidestep the the baggage. That's how to teach! I mean the accurate truth is that the only difference that matters between built in types is the compiler type checking, but if you only have one simple message to give... yep "size" is a better "take home" answer for the student! A physical thing trumps an abstract one, you dont confuse half the class... AND you don't have to say "another video later about that"... again(!) LOL. Keep it up Cherno I really like your stuff.
