I discovered enum classes the other day, and I was so happy. Classic enums are kind of annoying when they leak into the current namespace.

[@Ranakade]

Finally! A straight to the point explanation of enum! Subscribed!

Actually you can avoid the confusion with distingiushing the two "Error" like Log::Level::Error

Or use ERROR

Can you make a video for cmake...?

[@vertigo6982]

He would have to make a couple videos on cmake.. one video is never enough and barely would cover an intro to cmake.. cmake has decent documentation though which I find is better than video hunting because.. not every video is using your IDE/build system, or OS.. so there's different configs to learn depending on what youre building on and building for. I had a difficult time finding a video using cmake in linux to build something to put on git so I can clone it on my windows system and build it... Then I had to narrow it down more to finding videos on using cmake in linux in kdevelop... I quickly learned.. skip the videos.. just dig into the docs.

[@master_spike]

One of my favorite usages of Enums is as a function template parameter, with constexpr if statements if i need a function to do something *slightly* different depending on some options. It eliminates a lot of conditional instructions from compiled code while cutting down on duplicate written code.

[@marcandrei8061]

not great for someone who doesn't have a clue but as someone who knows c and is trying to move to c++ I really just need to learn oop so I'm thankful for his explanations that are more sophisticated than other youtubers that generally stop at explaining how to compile a program or write a variable or a function.

[@foomoo1088]

It would be awesome to have an updated version of this coving enum class as you mentioned, but also addressing the pesky issue in C++ enumerated regarding serialization and mapping to string names. (E.g. there’s a use-case for having ascii serialized assets which have enum values serialized as string names). Use of enum as bitfields (flags) is also another useful side topic. Thanks Cherno!

[@casperes0912]

Using 2^n for enum values means you can often do some bitwise AND/OR operations cleverly. Like if A = 1, B = 2, C = 4. If it's possible for two to be "active" at once, A+C = 5 which means if you & it with A it'll == A and if you & it with C it'll == C

[@ChaosB7ack]

Those are called flags, I've never seen them declared as enums tbh. Most times they are #defined since they are very much used in shared headers

[@casvanmarcel]

Very educational, you are a fantastic teacher Cherno. Waiting for the OpenGL series! Thank you so much for making these

[@DavidBChannel]

My lecturers made me forget what it's like to understand a coding lesson, thanks for reminding me! lmao

[@divyabhoi9584]

When you write Log::LevelWarning, does it mean that LevelWarning is a static variable belonging to the Log class?

[@GenericPhantom1]

Enums are integers behind the scenes. If you have a set of values you want to represent numerically you use enums

[@Special4ce293]

So far so good, I have 99% identical code to what you wrote, (just renamed a few things but kept everything consistent... However, I am getting a 'C26812' Warning. The enum type 'Log::LogLevel' is unscoped. Prefer 'enum class' over 'enum' (Enum.3).

[@UNRELATIVE]

Thanks,The Cherno.

[@batabatonica]

Man these are soo useful, i love this series

[@Delemaroth]

Convention for all other cases with Enumerators is to completely capitalize the words used in them. is that not the case in c++ development?

[@houaxiong616]

OMG! This makes so more sense! Thank you!

[@rcookie5128]

Once again I thought I knew everything about enums, but never knew you can explicit type the enum neither that you can directly access enums from classes without having to get the enum itself first (so Log::Error)

I know this comment is 2 years old already but, for you or anyone facing this problem...just keep practicing watching more and more videos in English, and also try to see vídeos of the person talking directly to the camera, it is easier to understand and make you get used...and don't quit studying English until you start to understand things, also try to talk to people in English, even by text will improve very much your vocabulary....just keep pushing, and eventually you'll be talking in English without even realizing, because it is a very simple language (my native is Portuguese)...another thing that I've done was changing every electronic device I use to English, and start to read every book in English instead of Portuguese, also, another big thing was start searching in Google in English...well, I hope you're not having problems with this anymore, but if you still do, this is what I did and it worked...

Hey Ian I think you should've talked about enum classes, the addition of enums in C++14? I think, enum classes change a lot of stuff about enums, so they are not just plain integers(well technically they are but you cannot compare two enums of different class types!

the way he wrote the enum ref in the main class (Log::Level) -- that looks like static member addressing, I see no static keyword on the enum, does that mean they are static by default?

[@smitadeshpande6525]

hi you can use refactor feature of visual studio for renaming a variable at multiple places automatically.

[@jscorpio1987]

I think he was doing it manually for the purposes of this tutorial so that we could see what’s going on more easily.

[@alex.ander.bmblbn]

a great example of how you might use it in real life is how you want to use boolean type in C: instead of having an integer taking two values, you go with typedef enum { false, true } bool; and there you go, you can use your good old true and false

[@alex.ander.bmblbn]

@Artem Katerynych the same way you can say that C has classes if you define a class as a structure. Im saying ORIGINALLY, without any additional includes

[@autumnleaf8483]

This is something in Roblox Studio(game development platform for Roblox, also learning that and as well as C++) but ENUMs work the same way how it works in Roblox Studio scripting.

Well i have a question that why did you : unsigned char with enum? I didn't understand the size terminology.

Unsigned means that it will not have negative values, and char is an 8 bit integer char: -127 to 128 unsigned char: 0 to 256
