Too slippery. Most rookie developers won't know where to quit and look for greener pastures. The benefit of learning C++ is the control you have that you don't get in other languages. That's all contained in the C subset of the language. Most of C++s additions to C are inferior versions of other languages features packaged to be convenient for those who want to retain the C level control. I don't find C++ productive as a transitionary language to teach you machine knowledge because C++ might fool you that an iterator concept in one of these higher level languages are as efficient as explicit indexed for loop. Because they _sometimes_ are in C++. Imo your advice is good for people who need to know C++ imo. It's contrary to prominent Cppcon presenter Kate Gregory, who suggests you don't start from the basics. The argument being that most of C++ has redundant features and the most modern stuff is the best stuff. So instead of indexed for loops, iterators or even ranges. You start with views. That's what I understood from her. I think you lose as much as you gain. Maybe the developer can write good C++ after that. But they will not understand the machine as clearly as someone that's sent concentrated time in asm or C (or a C like subset of C++).

Linux, SQLite, the SQL language itself, Python, Chrome, QT framework, to name a tiny number of them I've used the abstractions of in higher level languages. C/C++ is the foundation of the entire field.

C++ actually has tons of abstractions (templates, OOP, smart pointers, etc.), and IMO it could be called a multilevel language. You could feasibly write an entire C++ application without ever manually managing memory. It would be more accurate to say that the option is there if you want/need it, but you will not necessarily learn manual memory management by using C++. C is way better for getting a lower level understanding of things.

The claim of “you learn memory management using C++” was true in C++98 / C++03. With C++11’s smart pointers, you’ll not get manual memory management through a code review anymore. They’ll say: “Use unique_ptr,” or shared_ptr if unique_ptr doesn’t cut it. And rightly so. It expresses intent and saves you from many silly mistakes. There’s a library for a kind-of-GC smart pointer that avoids the destructor hell that can bite you with unique_ptr and shared_ptr.

One of C++ strongest features despite adding new things over time is the philosophy that the developers should not have to pay the price (in compile time, runtime resources etc) for any of them if they don't need it. With that said I can feel that C++ syntax over the years can feel a bit convoluted in places. But the control and flexibility of it has had me coming back for decades :)

If you have 20 different URLs pointing to the public internet it's a nightmare.

And peek at how C does it once in a while. After they learn how to do it in their GC language. Like not because understanding C and memory management at basic level is insanely hard, it's not. It's just that beginners are not so good at researching and finding answers when they get stuck too. And they're already overwhelmed by tons of new concepts, no need to add more on top of it. You have your 'developer intuition' now so it feels like you would crush it if your memory was erased and you started learning C as your first language.

C++ lacks an important aspect of OOP, namely message passing as alternative to function calls. Yes, many other OO languages lack it too, still it is important, it helps to understand how duck-typed polymorphism, decorations etc. work in languages like Python and Javascript, or how GUI work (GUI, being initially written in Smalltalk, makes message passing central). There are three nice ways to understand the message passing: the most difficult is probably to write Windows GUI programs using pure WinAPI. It has lots of unnecessary complexity, like writing virtual functions in plain C, or worse, and leaves lots of frustration-induced "why did they do that". A little bit easier is to really grok Qt, read source files of QObject and related stuff many times, and fully understand how its moc works. Of course, signal-slot system is not exactly the same as message passing, but in many ways it is very close. And the most straightforward way is to learn Objective C and write something for MacOS, iOS, or GNUstep -- it helps in understanding how elegant and effortless GUI programming is when the language is the native language of that GUI, and on the other side it allows programmers to go low level.

Having said that, people do crazy shit when it comes to market data processing, which some just do assembly for directly.

The fact that major slice of langauges for game engines, OS, and embedded are C/C++ says it all

Hi I'm new at javascript, what is a "rawdogged object" ?

Oh man, 14:55 spoke too hard for me. I just recently started getting back into c++ after doing some go and rust and man... I tried simply setting up Conan to build my project and my god was it -1 If C++ had a cargo like build environment/Package Management I think honestly it would be used a lot more

I started programming about 2 years ago, have learned like 8 languages, and still find c++ as my favorite alonggside python. A friend of mine at google says all of the backend of youtube is in c++, so it's very useful. I hate rust's BS in stopping you from doing what you want. Cpp gives you the power to do everything you could possibly want, which is akin to freedom, which empowers you.

Rust does have ways of forcing you to do things "more" correctly. Yes in C++ you can move fast, but forget to/miss-handle error values and you'll crash or worse, undefined behavior. C++ is still a great language though, but Rust is trying to help you rather than giving you complete freedom, it's just a difference in approach.

Just ask yourself... Python, PHP, Java, C# etc... What language were they _implemented_ with? Yep. C++. That's all you need to know. As some of languages matured they were able to self-host (be implemented in their own language) but PHP and Python are both still C/C++ under the hood.

Roslyn compiler for c# is written entirely with c#. And Java compiler was written with c and now is written entirely with Java now.. So rust was written entirely with ocaml and now was written with rust. You can make any programming language with any programming if you know how compiler work.. You can use lexer, parser generator, the create ast, then create VM or translate to machine code..

Cannot believe C++ is evolving this fast.

I agree, to fully appreciate Rust one must know & use C/C++ or assembler ;)... i just saw presentation about C++ when they are fighthing with mixing of abstactions or abstraction layers and i realised that borrow-checker already keep eye on this in Rust and they slowly try to recreate it. Also i saw presentation about compiler optimizations in Zig and seems they also trying to recreate part of it from scratch.

Learning any low-level systems programming language should be a requirement for every developer! Like you said, it helps a developer understand the basics of machine hardware and the hardware-software interface. Whether C, C++, Zig, or ADA, a systems language is valuable knowledge and goes well beyond the language. Whether you should become an expert in one of these language depends entirely on what type of development you wish to do. I would never hire an embedded systems developer who didn't know C and C++ very well. The reverse is not true however. I might hire a web developer who know only a systems programming language. I know someone who knows a systems programming language well will be able to pickup a web language.

Yes Go and C have similar syntax and philosophy obviously Go has many more abstractions but is a lighter language like C where Rust is more comparable with C++. Learning Go also exposes you to pointers similar to C although memory management is more involved with C you really want to simplify your memory management and own it rather than relying on a garbage Collector then fearing it and trying to get around it when performance becomes an issue. And when that time comes C becomes your friend that you wish you had. It’s an exceptional language.

V Timely! I just wrote my first little C++ program yesterday for an arduino unit (a 4 note "keyboard" with button switches and a single LED). It was like 50 lines and took up 3% of the unit's available memory

I think everyone should learn C to understand the basics of low-level programming and memory management, but *not* C++. C++ has a ton of features and while you don't need to learn them, the fact that they're there is noise if you're trying to learn low-level programming.

@@blubblurb This 100%. The best thing about learning C, even if you don't use it, is that it will make you a better programmer in higher-level languages. It provides better understanding into the cost of all the abstractions other languages offer that many take for granted,. It makes one become more conscious of what is really happening a few layers down., and adjust the coding style accordingly, resulting it more optimized code.

I agree C should be learned first. Because C++ was created to extend C and simplify abstraction C developer did a lot manually. But there are important concept that are better explained with C++ than C. Like the dynamic polymorphism (virtual) and static polymorphism (variant). Like the notion of compile time vs runtime. Like difference between copy vs move, l-value vs r-value, RAII (how to bind the lifecycle of a ressource to the stack to be cleaned automatically after use). These concepts are important whatever the language you use, because they are always there in different form. Look at how horrible it is to manage lifecycle of ressources different from memory (like file or connection) in GC language like Python or Java. They have fixed memory but all others are still badly managed. Some language are good to hide it temporarily but a good senior developer will always think about it in his mind.

I think learning a subset of c++ is better for overall programming experience where you stop just after classes, inheritance, polymorphism, and pointers. Don't do smart pointers or all that unless you're engineering in c++. The reason why I like it better for learning than C is because classes and OOP are a massive part of engineering. C++ allows you to learn classes when you're ready, but build plenty of things without them in a c like way

When you finally grasp cool concept of lambdas and find use for them but then you realize that multi layered templates are still haunting your brain 💀💀💀

@@OryginTech Yes. I work at a firmware shop that serves high end clients, C is still king with some cpp here and there. Rust doesn't do anything for us besides prolonging compilation times. Nowadays it's trivial to write memory safe software if you know what you're doing and use appropriate tools.

It's not just done with FPGA's (but yes, it's one of the more important aspects) and it definitely isn't done using OCaml in a wide spread sense. It's done using Verilog or VHDL (and last I checked, C/C++ was actually among the most used languages, where *all* the other top languages were hardware description languages like the ones I mentioned, making C/C++ stick out in this field a bit). But that's not even it. I've seen talks from HPC-people in the finance industry and apparently, language and all that stuff is "irrelevant". You need to be *on site* as close to whatever system *physically* to reduce the latency for how fast you can respond to an event. I.e. you need to purchase a building somewhere that's neighbor to the system you're working against, because that will reduce latency and give you the edge needed.

At college I made the mistake of taking C++ before C. But that was the difference between CIS versus CS in the mid- to late-90's on campus, before even Java took off. I've been waiting for something like Rust and Zig, but if the vast majority of jobs out there are web dev, then why? It's not dead yet. What scares me is there are beginners using Python as a first language. Sorry, but it may be easy and natural, but it's so non-performant without Cython and all kinds of crazy shit logic. C++ still wouldn't hurt a young student. It's on our OS still. C/C++ devs do have that valid argument about Rust and object lifetime, and the inherent tradeoffs. I personally might choose Java over C++ if I started over, but I would still have to take C. Web dev is more like.. fml. And people start out like that, taking system security for granted, never knowing the ins and outs. C++ is like learning your OS before you develop on it, still relevant.
