If they're related to C++, then yes. In modest quantities.

Reason: tried this folder and that folder(just not the folder in LD_LIBRARY_PATH or -L/path/to/dylib), no such dylib file
I would also like to share another possible solution to this problem: https://stackoverflow.com/questions/17703510/dyld-library-not-loaded-reason-image-not-found

Hi, is there a feature to compiling binary with rwx in .text ? on msvc ? ı think ı remember there was a flag. researched but couldnt find anything neither on web and stackof

Why would you want write permission on .text ?

Does anyone knows the rational behind the names such as 'sockaddr_in' or 'sin_addr ? is there any kind of source that explains why they named them like that ?
xhunter
(This is related to Network-programming in C)

I don't remember much. https://beej.us/guide/bgnet/ this is one of the best guides I've ever read to sockets and it might have some of what you are looking for
Dalme
Please note I haven't read it recently but as far as I remember it kind of tried to make some sense of the (apparently) nonsensical stuff in socket programming

Thank you. I'll give it a read

guys, do i need to explore something BEFORE to explore C++?

Maybe computer architecture? Or how is the processor and memory structured?

That’s not an Assembler, but would be good enhancement

I think actually better to learn a little bit c first. Because if you are learning from YouTube, most of the C playlists are made assuming you are brand new in programming. But a lot of C++ playlists doesn't cover the basics that much. Learn the very basics like data type, variable, conditional, loop, recursion concepts in C and then move to C++.

And there's no good course on C++ in English on YouTube

yeah, there are a few good books, that i actually have))
but i don't know, what better: learncpp.com or PPP/Lipmans books

AFAIK learncpp is not bad, but I'd choose the books

There are some good courses on YouTube in Russian, they are actually mentioned in the channel also. But if I remember correctly, they assume that the learner knows basic programming

guys, do i need to explore something BEFORE to explore C++?
It’s not necessary or a prerequisite to explore computer architecture and assembly language to learn c++.
George
You could start with any good resources which are either free or paid only if they are updated to the current c++ std 23 or at least up to c++20 std
George
Once you completed basics, templates, class & oops concept, lambda & other new c++ features, you can learn data structure implementation in C++
George
Followed or in parallel QT or other C++ library or even game development to apply what you have learnt.
George
C++ is vast and have plenty of feature, so learn practically than following lectures and website articles

My opinion is generally slightly controversial, but I would advise learning how to use a Linux based operating system and then learn C++ on said system.
I have been teaching C++ for 7 or 8 years and Microsoft Visual C++ has very cryptic error messages and error reporting, and that is an everyday struggle for my students

Thats nice, cause my main system is Linux

How to call placement new for std::vector<std::vector<T>>?
Smth like:
ptr = new(ptr) std::vector<std::vector<T>>();

I guess vector allocates meme for data internally. WIth xour code you will end up with top level object allocated in your memory but the data memory will be allocated just somewhere...
Ziky
I am far from expert but looking at manual https://en.cppreference.com/w/cpp/container/vector this look promising:
template< class T >
using vector = std::vector<T, std::pmr::polymorphic_allocator<T>>;

I have struct which contains this vector and I allocate memory for this struct using custom linear allocator using malloc
Ziky

As you found out malloc will not call constructors of c++ objects. What are trying to do?
Ziky
TBH I haven't used c++ for years :D isn't allocation of that struct using new solving your problem?

I often see on the Internet that Steven Prata’s book C++ Primer Plus is a bad book for learning, tell me, is this true?

Hello I am pre final year CS major student. I am working on a project and I need some help
Paranoid
I was trying to develop a library on concurrency and parallelism similar to threads. I have barely started and made working functions, creation of threads and joining. Can you guys suggest any improvements? Also is this a good project for a fresher's resume

The joinAllThreads function would be cool if you can implement it using mutex and conditional variable
\Device\NUL
pthread_join is calling futex every single time it's called while Windows has WaitForMultipleObject that allows to sync Objects with only one system call
\Device\NUL
That would be a huge performance improvement
Paranoid
Ok will work on that. Thanks a lot for the feedback :)
\Device\NUL
You also might want to use C11 Threads instead of Pthreads for more portability

https://gist.github.com/ammarfaizi2/04b2cdb70f440e6f4ec7929b6b6341b8 Here's some examples that will help you writing it
\Device\NUL
It use mutex and conditional variable instead of thrd_join

Doesn't that use Window API which increases time to execute
\Device\NUL

What? C11 Threads is already out from 2011. MSVC and GLIBC already implement it
\Device\NUL
Pthreads only available to Unix platform while C threads is available to all platform that support C
Paranoid
Okay will look into it
