C++ gets a lot of hate on the internet, and there may be good reason for that. I think C++ is misunderstood, and there are a few simple reasons why. Despite being designed around 3 simple principles, the language has inflated to have a ton of features that are either too complicated to understand, or too powerful to implement without making your code base unmanageable.
But, should you learn C++? Yes. There are a few caveats though.

You made this video just to get drama. No you should not learn C++. Lots of people know it, few companies use it, most are moving away from it, there are better languages if are starting a project. Anyone leaning C++ will only annoy experienced users. Like you said. The first language anyone should learn is python, then Rust or C, then TS or JS. Maybe Bun. Everyone can use Python because there is always some quick little task that you can get done with python in a few minutes that will make any computer users life better.

I like how people always talk about "which language should you learn" as if we're often given a choice. In my experience, unless you're writing stuff totally from the ground up (or just wading into a new language as a hobby), which language you use is almost always dictated by what software you're developing for, or what your job or school requires you to use.

I wrote C and then C++ for years as an embedded software developer. As the language grew more and more complex, I noticed developers very purposely wrote more and more complex code which took longer and longer to read, trace and understand. Worse, there was a convoluted arrogance that came along with it. If you couldn't understand their extremely convoluted code, you were a lesser person. Few acknowledged that convoluted code was bad code. And discussions about the language replaced abstract discussions about what the compiler and processor would have to do to accomplish something. It became essentially _wrongthink_ to even consider how a compiler would implement code. While I was constantly striving to simplify the organization of data and the processing of it, my coworkers were constantly building empires of more and more complex code to their own glory. They _hated_ me when it got in my way and I simplified it.

Professional C++ programmer here: The thing is that C++ has a steep learning curve and that most developers just don't want to invest the time to learn the language. Just as you've said: with great power comes great responsibility and rarely anybody wants to be responsible because it is hard. Also C++ is usually taught wrong and rarely do teachers or courses explain that, for example, raw ( C ) pointers are not evil, they just cannot be owning pointers. I agree with your suggestion on how to learn C++, I would just add that after learning C, fammiliarize yourself with the abstractions that the language introduces, by reading books and watching convention lectures. That way you get a bottom up ( learning C and the memory model) and top down (learning abstractions) view of the language. You just need time to understand the language, something that most people do not have today. C++ is not a perfect language, but it does not deserve the hate it gets.

Like solid code sometimes just wont work because theres some quirk of the language or compiler or something that just screws with specific implementations that seem like they should work.

@aleksandarnikolic2441
@aleksandarnikolic2441 Рік тому
@@user-sl6gn1ss8p Well, the thing is owning pointers are pointers which manage the lifetime of the object they are pointing to. That means that smart pointers in C++ are owning pointers because they have to destroy the thing they point to at the end of its lifetime. If A owns B, that means that A has to destroy B when the time comes. That means that Non-owning pointers do not manage the lifetime of the object they point to, they just "look" at the object. They don't have any obligation to the thing they point to. That is why raw pointers are "ok" to use in a non-owning scenario. They are great if your function requires a view to the object. Nothing is hindering you to use pointers as you wish, but abrstractions like these are really handy when you have to reason with code that you are unfamilliar with. The purpose of abstractions is to carry intent. I hope that I made it a bit clearer. :)

Agreed, working on a project that stretches 4 platforms (windows, linux, microcontroller, embedded linux) and build systems are a pain to get right if you don't want to enforce usage of a specific IDE. CMake frustrated me to all hells with how most of the methods turn out to be "not recommended anymore" but then recommended methods for cross-platform use are lacking BIG TIME (especially how msbuild wants release+debug setup, I ended up dumping that), overall CMake was really unintuitive. NMake started fine (basically a simple syntax change from Make) but became a real drag once it got a little more complex with how badly it is supported. So I now use CMake for windows so I don't have to deal with manually maintaining msbuild project files, Make on Linux, Make for Microcontroller, and a simple CMake + SH for embedded linux.

C++ is and will likely always remain my main language, and the unique features of C++ can be quite beautiful in some cases. I have been working with the QEngine library for simulation and optimization of quantum physics, and it makes extensive use of templates and operator overloading to allow me to essentially create a Potential or Hamiltonian (a kind of functions which tells us how a Quantum system evolves) as a C++ object, by literally writing it as an equation. But I absolutely agree, if you try to use "advanced" c++ features where normal C would do the jop it gets messy very quickly, and the error messages are not great, especially when templates are involved. I routinely get single error messages so long that they can not fit in my terminal.

The first programming language I ever learned was IBM 360/370 Macro Assembler which is actually rather high-level as far as assembly languages go. They thought we should learn this before moving on to COBOL and CICS. Also, AL was the "washout" class. If you can't handle that you don't belong here. When a friend of mine was in the same program years later he asked me what he should learn after AL. I suggested C because it was the new hotness, the syntaxes of many other languages are similar and it's still low-level enough to let you do whatever you want. It's a good baseline. I've since learned that you can also do object-oriented programming in C using pointers to structures of pointers, but that makes my head hurt almost as much as the SmallTalk-style objects in Objective-C. So much is already written and can be written in C++ that it makes sense to know it. But while it's relatively easy to know C, if not always the best ways to use it, it's pretty impossible to know all of C++, much less how to use it well. C++ is a Very Complex language, though still low-level enough to be one of the fastest languages out there. Rust is more trouble than it is worth. I prefer Swift. It feels much more natural to me. But still, many device drivers are still written in C++ or even C so it's worthwhile to know them.

As someone who started with Java, C++ is very rewarding. I get the same OOP and functional features I'm used to plus equally great libraries without the overhead of the JVM. C++ is definitely *not* a "better" C. C is much easier to tinker with and iterate (without worrying about brittle design choices).

Learning C first will tend to lead a developer towards a C-like C++ style. This tends to defeat the purpose of C++; See Kate Gregory's talk "Stop Teaching C". Avoiding sugar is also not the best approach, and in fact the range for loop over a std::vector generates less assembly instructions than using a traditional loop variable. You can prove this in Compiler Explorer with -O3 and is mentioned in Bjarne's book A Tour of C++ 3rd Edition. This makes some sugar in C++ what Jason Turner calls a "negative cost abstraction". Also "near zero cost" is not quite right. The language design involves what they call the Zero Overhead Principle, which is often misunderstood. This means not that there is actually zero overhead in using an abstraction, but that if you implemented it manually by hand using only C or assembly, you wouldn't be able to do better. At least, that's the goal...I won't go into how exceptions allocating and Run Time Type Identification are clearly in violation of this.

About C++ security, I think most of the common problems that Rust solved, C++ already did too. The "problem" is that while in Rust they're there by default (and you can't escape it), in C++ they're opt-in (but highly encouraged by the community) features or patterns like smart pointers, RAII, etc. Smart pointers are, in practice, C++ ownership system. C++ has a legacy of 30+ years, so a lot of legacy code and "legacy programmers" still use the old verbose, unsafe patterns, it's also the style teached at most universities (remember folks, professors usually don't stay up to date with the industry or language features). But I see a lot of effort by the community to enforce these new patterns and document them. For beginners it's a challenge to soak up and distinguish so much legacy knowledge together with the new knowledge. But I'm having a lot of fun in my journey.

Companies I have worked with have flat out ban threading because it just causes so many bugs in what needs to be a safe system. Lifetimes are just never explicit in C++ you just have to hope things are documented well. C++ is not bad but it has years of issues that cannot be fixed.

It took me days to figure it out because I checked if it was valid the line before I passed it. Multi threading itself is not that difficult, but using it efficiently usually means there are a lot of side-effects that become hard to keep track of.

Even if you later learn a language unrelated to systems development, C++ gives you great insight into how to make more performant code. Other languages are also much easier after learning C++. Without learning pointers, for example, it can be harder to learn how all the objects connect together in C#. (C# has pointers called references, but they hide them). If you decide to go for a higher level language, try to not depend on a framework (like Unity) to learn the language. Otherwise you will be dependent on the framework and you won't learn how to structure the code on your own. C# is a really good language, but all programmers should learn C or C++ at some point imo to get a better understanding.

C++ was my first language in 2015 when I started a physics degree: as part of an *introduction to programming*. It was tough. To this day I don't know if the teaching methods were disadvantageous or if the language is genuinely a poor choice for baby's first programs. Because we started with basic control flow and then structs that could have just as well been C, I think they just didn't want to introduce us using another language once the time came for abstractions and other OOP concepts. I've since ditched that degree and just last year restarted uni with a bachelor's in IT. Our first language there was Java. For all the hate and memes, it's an easy language to learn (with lots of often unexplained boiler plate). Now we're doing C for the operating systems module and it's... fun. I'm just at the start of my low-level programming but I'm looking forward to where it takes me, and to the things I can build on it - including C++.

I worked in C for about 2 years in total and about 1 year in C++, and while both languages can be pains in the ass in their own ways, C++ was way more convoluted, unintuitive and tedious to work with in my experience. High-level, near-zero cost abstractions sound good but unless you can somehow solve memory safety without GC, you're building on sand. C++ couldn't quite achieve that, though many of its features and libraries are undeniably an improvement over C. Rust managed to do decades later what C++ couldn't back then. In conclusion, I wouldn't use C++ for any new project anymore unless I had no choice, like an Unreal game or a Qt application, though I wouldn't be surprised if both already have viable bindings in other languages.

I think C++ could use a complete second standard library altogether, as complete as the current stl but without the history. Most game engines use stl minimally because it's ill suited for game development, though better nowadays, there are still many reasons to not use it.

We have of course later been introduced to raw pointers and stuff, and as a result, when needed for programming microcontrollers and stuff, I had kinda knew C already and stuff like Java and Python was really easy to understand since C++ has everything. But yeah, learning and using it for my personal projects (e.g. using it without an OS and having to reimplement some of the standard library), it has now become a never ending rabbit hole of getting to know everything that the language has to offer. Also, C++ is not a superset of C in all, but a language which is 'mostly compatible' since it has a different linking and starting with C99, C has things that are not supported in C++, like designated initializers, some keywords and probably other stuff that I don't know about.

Taking the char * example given in this video, I do agree it's use is frowned upon except in the specific case of cross-platform messaging (where you want to guarantee no compiler dependent behavior/sizing, which even std::string doesn't provide across platforms/compilers); use of std::string is *much* preferred in all cases because it's a proper object, with all the features and protections that come along with it. The issues I come across with C++ are typically one of the following: 1: The fact the feature set is so robust turns people off, because there's multiple ways to accomplish the same task. Example: Iterating over the range of an object; the *old* way would be a FOR loop using the start/end values and in iterator, but you now have ranged-based FOR loops (as of C++11) that do the same thing in an easier syntax. 2: Thinking of C++ as "C with Classes" and not taking advantage of the fact C++ is (mostly) an object-oriented language. 3: Trying to use C++ in a role another language can do better.

A lot of the code shown here is very dated, such as using begin() and end() to construct for-loops instead of range based, as one example. Compiling errors have come somewhat further, too. If you're stuck coding in a C++11 application, then fine, but it's over a decade old in a language that sees major adjustments every 3 years. Sadly, the main point almost applies MORE to modern C++, imo, so I guess it's a moot point...

I switched from C++ to C a few years ago and never regretted it. The main reason is C++ is so endlessly complex that takes a big cognitive toll in your head while developing. There is no such thing as not paying for features you don't use, because even if you don't use them, you still have to know about them and deal with them. You can't just ignore knowing about exceptions, move semantics, overload resolution, etc. C++ also likes to hide a lot of code from you in constructors, destructors, operator overloads, etc. so seemingly innocent statements like x = y + z; might execute all sorts of code from all over the code base. You really have to have a good knowledge of the code base to understand what's going on. It makes it hard to ballpark how fast or slow code might be. Switching to C freed up a lot of mental capacity I can now spend on actual problem solving.

I agree, c++ is awesome. You get the low level control of C, the feature richness of python and in some cases even syntactic sugar that is close to as readable as python (like range based for loops and structured bindings), but all this feature richness makes it quite hard to learn. And template errors are an absolute nightmare to read and fix. I would argue that they code alleviate a lot of the pain by improving the readability what the compiler spits out when you messed some template code, or use of a template library up.

@@tuluppampam yeah the main issue is that idiomatic, modern c++ requires you to use use many advanced features of c++. In order to actually understand them it's best to learn old school C++ first and then move on to the modern features, because the necessity for modern c++ only becomes apparent when you understand the problem with old school c++. The issue I see here is that many people in the c++ community are quite toxic when it comes to newbies not using "the idiomatic way" of implementing something.

Yes templates when coupled with all its types, and other features of the lanaguge like passing a lambda to a template parameter of type std::function or etl::function(if you are in embedded domain) IS VERY difficult and annoying to read. But then there are good and bad programmers... I think what also matters is to know and understand how you can leverage what compiler optimizations are available. Make the code readable and maybe enable an optimization of -O3 in production code... code space reduced but code still readable

I have used a lot of C++ for developing a video game engine. I can confidently say that C++ templates are Witchcraft. Remember: they are NOT the same as generics, which you would see in higher level languages, even though they look similar on the surface.A templated function is NOT a single function that takes a variety of arguments; it is a meta-function which generates multiple, isolated functions during compilation, with different memory locations.

Good for you. I think it's great that you learn C++ rather than Python. IMO Python is bad as a first language because it gives you a bad intuition about data types, contrary to any statically-typed language, like C++. And if you ever feel overwhelmed by C++, you can always switch to C. Though, my recommendation would be the same as in this video: to first learn C (as it's just as sophisticated, but much simpler), and then move on to C++. But if C++ excites you more, go for it.

If its working for you, it doesn't really matter. Whatever language you use, it just needs to be good enough to make the projects that will allow you to learn what you need, without being so frustrating so that you might lose motivation. I think python is a good stepping stone and I like it for quick proof of concept type things. Potentially, python lets you skip the syntax and focus on learning how to give computers instructions first... control flow and all that, but its also allowed me to adopt some bad habits, like overusing list comprehension to quickly define arrays in a sometimes unreadable fashion, though I'm sure there different sorts of bad habits you can pick up from different languages. There's also some cryptic errors in python, usually around how things are copied or passed around, which make a lot more sense when you know about pointers and references, after all python itself will be written in c.

@avfr You assume people can only do isosceles triangles and temperature converters after 1 month of C? Get off your high horse lol. Not everyone chooses C as their first language. If you've got plenty of experience in, let's say, Python and JS, it wouldn't even take a month to learn C, the standard library is not that big, especially compared to Python and JS. Doesn't mean you're suddenly being able to code kernels and stuff, you'll need way more knowledge than just C for that. It's like spoken languages. Just because you're proficient in English doesn't mean you'll be the next Shakespeare. Or the next Mozart if you can play the piano. _ As an anecdote: after seeing Haskell for the first time I immediately fell in love with it. Got myself a copy of "Learn you a Haskell for great good" and worked my way through that book in less than a month. Delightful read! I wasn't able to code anything I want at that point, but oh well, it's Haskell after all. Fiddled around with it for a couple of months and eventually stopped digging deeper. I'd say I'm pretty good at it now, though I only really use it to tackle and solve projecteuler problems, never used it for professional purposes. I can say with confidence that it boosted my abilities in Python(mostly data analysis and simulations, if we're talking about money making :)) like, A LOT, as well as my problem solving skills as a whole. It started as a recreational activity, for the jest of it, and now I'm a better programmer. Am I a Haskell god? No. Have I learned the whole language? No. Who cares? And who cares what and what not someone can do after 1 month of C?
