| >If you want people to switch to something better, make something better. We already have C, which is better. It existed before C++. It will exist long after C++ is dead. If you don't over-architect and over-abstract your code you can be more productive in C than in C++ precisely because you avoid the kind of nonsense that this article (and the endless other articles about overcoming C++'s shortcomings and cognitive overheads) talk about. In the time you spend waiting for C++ code to compile, you can instead just write more code in C. Look at all the articles that get posted here about C++. There was a post a day or two ago about trying to work around C++ compilation times. How long does it take to compile C projects? Not long at all, if you follow standard rules that have been well-known for decades like forbidding #include in header files. >If all the other compilers and languages were THAT much better, they would be used. Argument from popularity/Blub paradox. If C++ is so good why does it need to be constantly updated and extended? If you think C++23 is better than C++20, then surely you accept that C++23 can at least potentially be worse than things that already exist. --- People have an attitude towards C. They think "oh but what about std::vector? I will have to write my own containers". But 90% of the time you will have good enough or even better performance with a few lines of code. Often you know statically the maximum size and can just allocate that at compile time, or you know before filling a collection what the size will be. In C++, most code dealing with vectors that I have seen pre-sizes the vector anyway. That could just be a 'malloc' or a static array. The result is that you compile in debug mode and your program actually works, you can use a debugger, everything Just Works. Programs run at almost full speed in debug mode, and debuggers work. It's glorious. In C++, you spend a hundred thousand lines of code reimplementing standard library containers anyway because anything more complicated than std::vector is unsuitable for non-trivial programs, and then the only way your program will run is with optimisations on, because your 'zero-cost' abstractions are actually very high cost if you aren't compiling with -O3. Oh yay I have a big standard library in C++. Thanks for saving me from having to use the old ugly BSD sockets API to do networking. I can use a nice modern networking API in C++. Oh... it doesn't exist? Oh well, I'll use a nice modern filesystem API in C++. Oh, it only was added recently and lacks basic functionality? Oh well, I guess in return for learning the 50 different ways of initialising a variable, and all the subtleties of argument-dependent lookup and glprxvalues and template deduction guides and template⟨T=std::enable_if⟨std::is_void⟨void_t⟨int⟩⟩::type⟩::value⟩ I will get the benefit of using a high-quality standard library that contains std::regex and std::random and std::chrono and std::thread and std::vector<bool> and std::unordered_map and all the other VERY high quality standard library facilities provided by the C++ standard library! Oh they're all crap. Pity. |
You maybe can write small program easier on C as long as you can fit everything in someone's head. And that's why all complex low level programs are written in C++ and not C. (With the Linux Kernel being an exception, because of its stupborn maintainer)
And what about the drawbacks mentioned on the article? 99% of programmers don't need to care about them. The reasons such article exists is precisely because some people love C++ and like to play with their language.

Uh? To adapt and evolve to a changing environment. Instead of stagnating and becoming irrelevant. If it is so great, why is the iPhone constantly release new models? Why do every maintained software release new versions? And that's why you should use C++ instead of C.
