networking is not the main purpose of C++
Anonymous
It's a general purpose language
BinaryByter
Well yea
BinaryByter
but you can use a third party library if you want to
BinaryByter
And it shouldnt really be a problem

I've never understood the hate for the pointer
It's not hate, they're not meant to be used in some instances.
But in some cases, pointer can't be avoided.
C++ differentiate btwn these two cases, hence reference
BinaryByter
and as said C++20 will improve that

20 years after I have been born, C++ will have networking xD

Well, it can still use the kernel syscalls though

ASIO is being updated frequently to reflect the standard networking proposals.
Plus there are many other libs u could use.

Yeah, that caused a problem when I was trying to port some libpcap stuff to C++. ended up leaving it in C because I didn't know how to use functions as parameters in C++

I even read the first proposal were older than u are

I suspect I could have used another library but my employer really wanted to stick with libpcap

And that's the problem with C, it's development, developers are STALE.
Virtually none of them use C11.
While stats shows a good number of C++ guys using Modern C++.
I am alwayz on the bleeding edge

U have to learn C++ from the correct sources before u can appreciate it.

apart from the theory of what you are implementing

I think the thing is, I don't work on big projects, i spend 2 or 3 days writing a PoC and then it's done and I probably never touch it again

Hi all,
A quick question for all using C/C++. In which scenario is C preferred over C++? C++ is an OOP extension to C. But if I am not wrong it can be used as replacement of C as well right? (Like a functional programming language). So why C?
I know C is heavily used in some places - Linux kernel, etc. But if I am not wrong the time linux kernel was originally written, C++ was not mature enough. But now its a different scenario. So why C now? Does it provide better memory management? Or any other reason?
C is only preferred :
1. When there's no C++ compiler or a decent C++ compiler.
1b. Maybe an FFI interface for an interpreted language
2. When u want to torture urself by urself and for urself.

C is an instrument which can be fast-learned (compared to C++).
C is close to hardware as possible, but still portable - that's why preffered by _any_ EE there over C++.
C has standart ABI.
C++ is almost a garbage without userland libraries, belive me, I'm making C++ project in embedded.
C has lots of UB. C++ has tons more of UBs.
After C++14/17 I'm attracted to it and many people too, but to make system-level job you need lot more knowledge of C++ than you would expect (compared to C).
1. Where is the proof that C has a standard ABI ? NONE!
2. C++ gives u the option to easily implement ur own userland libraries, believe I'm doing it.
3. C++ is even better for embedded if u have a good compiler.
- With C++, u can get a smaller binary size because there's no code duplication like u have in C.
- RAII is a killer feature C is still dreaming of.
- Embedded C++ is easy because u only use subset of standard C++, no exception, no virtual, ...
- U've got power of : Templates, RAII, strong typed enums, Lambda and closures, OOP if u need it, Easy FP for we FP fan boiz, a well written embedded stdlib (third party: etl, EASTL...) with most DS and Algos, and it's gonna get better with C++20 features like Concepts and Ranges. C is still stuck at C11 that virtually no one uses.

With every iteration of C++, C obsolescence increases by a power of 10.

I will only write embedded C if I were captured in North Korea, because ... we all know why.
Other than that, all C code bases are questionable

C++ compilers do many things that a C compiler would let the runtime do
Jussi
Tell me how gcc and g++ differs when it comes to optimization?
Jussi
Well if you're a terrible coder, C++ is better but basically both gcc and g++ are so shit at optimizing code that well your points are not valid
Jussi
Sorry for that message, what I'm trying to say that you can optimize your code as well with C than with C++. And I would say that on most cases C++ creates much bigger binaries
Jussi
I don't know how you code C but I usually get much smaller binaries with it
Jussi
"- With C++, u can get a smaller binary size because there's no code duplication like u have in C."
Code duplication is like the only part where the C compiler can optimize the code lol
BinaryByter
BinaryByter
please do so in an empty group
Jussi
Still doesn't make your argument valid :D
BinaryByter
idc about you thinking that my argument isn't valid
Ибраги́м
I don't know how you code C but I usually get much smaller binaries with it
Because u write single function in C++ with template and compile-time dispatch, while u write like 2 or more functions in C for the same task (if u decided not die in MACROS).

"- With C++, u can get a smaller binary size because there's no code duplication like u have in C."

Really? And C++ compiler can't?
But I mean duplication that are used not the ones that aren't.
Jussi
I don't understand the point
Jussi
if you have a function that takes a template, for example square()
Jussi
In C You must write 2 functions
int square() and double square(), right?
