After watching accidentally a video of yours, I found you an awesome teacher and I've completed the whole series in a matter of days, never gets boring.
You really motivated me to seriously learn this language (I did know most basic things but was lazy and stopped), I hope you continue doing videos, trust me it's going to be a very valuable library.

[jaesiraki]

Such a modest energy and I can actually understand what you're saying. Thanks!

I am happy you make these videos. Because I study Computer Science in my university and it really helps me understand information which I didn't get in my class

[chinmaydas]

Sir, now We need more advanced c++ series from a great guy like you, many many thanks👍🙏🙏..

[KostasOreopoulos]

static_cast also helps to avoid removing constantness that can be easily done through c-style casting

[leixun]

*My takeaways:*
1. Implicit and explicit casting - C style 1:53
2. Static cast - C++ style 4:15
3. Why we want to use C++ style cast 4:44
4. Dynamic cast - C++style 8:44

You explain very well. And youre the only one who doesn't use mac book.

I've read somewhere, that it's actually faster and more efficient to use the C++-style casting, because if you use the "old style" casting, the modern compiler will try to attempt every c++-style casting in turn (const -> static -> reinterpret) and return the result of the first successful cast. But if you use one of them explicitly yourself, you just do it directly, without extra steps.

Thanks a lot, your videos are always the easiest to understand :)

[SoloR]

Appreciate the awesome series so far. I still reference your videos when I'm not 100% sure why something works. Anyways.

REQUEST: Could you do a video on std::string_view vs. std::string, and when to prefer to use one or the other?

[itsmaxim]

another drawback of (C)style casts is that they will attempt every cast type until one works, meaning the result won’t necessarily be what you expect

[gayusschwulius]

It's amazing. I have been using C++ for half a decade and written quite a few rather complex programs, yet there are still features I didn't know, lol.

[Miketar]

An important point that I realized looking at my casted variable types, the variables do not actually change to the casted types, only the data is changed. So the variable doubleVar = 5.5, will send 5 when casted as an int, but it still remains a double.

Any updates on the dynamic casting video? Really interested in this as well as further information on RTTI and reflection in C++. Not something that is clearly and concisely explained online! Thank you for all your helpful videos.

[parabalani]

I can't believe how accessibly you explained this

[MrHelio]

Although I'm making some effort to learn C++ style casts, I also prefer C-Style casts. The only thing that C++ style casts ( a part from dynamic_cast) have useful is improving code readability, but I see them somewhat confusing. Working with C-Style cast is far easier.

8:20, no actually your explanation was perfect and very understandable. thank you

[stewartzayat]

Could you make a video about memory allocators, like memory arenas?

[pablo]

Hi Cherno! I am currently studing at 42 school, and your videos are so helpfull. So you know!

[syntaxed]

Any chance you can go more indepth with c++?
E.g Software patterns, etc, how to structure/organise code, superclasses or not, how to achieve loose coupling etc.
I feel all of this basic stuff has been done, its all over youtube, the horse is not beaten...its a wet pulp at this point :D Just a hint for future content!
