I’m not too familiar with C, but I was under the impression that C++ was deceloped as a superset to C, and was capable of everything C could do. Is that not the case?
Every programming language is an abstraction layer between the programmer and the machine that will run the code. But abstraction isn’t free. Generally speaking, the higher the abstraction, the less efficient the program.
C++ optionally provides a much higher level of abstraction than pure C, which makes C++ much nicer to work with. But the trade off is that the program will struggle to run in resource constrained environments, where a program written in C would run just fine.
And to be clear, when I say “low-end hardware”, I’m not talking about the atom-based netbook from 2008 you picked up for $15 at a yard sale. It will run C++ based programs just fine. I’m talking about 8- or 16-bit microcontrollers running at <100 MHz with a couple of hundred kB of RAM. Such machines are still common in many embedded applications, and they do not handle C++ applications gracefully.
And speed too. A small program using only C features can compile 5x faster with a c compiler then a c++ one. (GCC will use c++ mode on a .cop file so make sure it is .c)
That’s true, but they’re working on an ABI implementation. It’s no mean feat with a language like Rust. A quick search around the Internet found various possible candidates, though many of the discussion threads have petered out.
Its cross-platform support (not just for using but also for building it) is not there yet, and it is quite huge and unstandardized with only one full implementation. I’d agree the last part will change with age, but given the frequent large changes and feature additions I am afraid it will be harder and harder and it is simply too complex and fast-moving for many low-level applications. It is closer to C++ than C in my eyes. I’d be happy seeing it replace C++ though for its memory safety benefits!
I wouldn’t say “need”, but there are possible improvements to ergonomics and safety that wouldn’t make the language itself more complex or high level. I think it does its job quite well though and will be here for decades to come.
Ada has been around since 1983 and is objectively superior. Yes I will die on that hill.
It’s too bad programmers are all such egotards they think they can write bugfree programs in C, while whining about how “restrictive” a safe language like Ada is.
Jeez this is so true. I struggle daily to stay on top of the code and docs I have to review, answer people who are pinging me in slack, and being in meetings… I want to actually get some shit done!
