You may copy your code and place it inside the pair of ``` brackets

If you need to send the whole file pastebin exists

Antispam got his ass

Yeah I see it now, but there's no bot msg for some reason

CodeByOm is now approved by the group admin and can send messages without any restrictions Now it's working fine ☺️ See spam? Quote the spam message in the group and reply with /spam

should be good now

Thanks 😊

Yep, it worked, thanks. And overall, I appreciate having your bot here. Despite the false positives and stuff, it just happens in spam detection.

thanks

It's not complete. I suppose telegram doesn't support high enough pfp limit to include all frames.

hello guys i hope you have a good day until now i want to read about pointer in C but i dont have a good resource for that i found this book<Understanding and Using C Pointers by Richard M Reese> but i dont know it is good and usefull of not if you can help me for this

Hi, I haven't read that book, I would recommend Beejs guide to c book. I'm currently reading it. Worth it. Actually in reading advance pointers chapter

Hey guys, I implement Win32 events on top futex for practicing system programming. It use new futex2 API and optimized for Linux like futex_waitv for emulating WaitAny and io_uring_prep_futex_wait for reducing system call emulating WaitAll. Any feedback or suggestions would be greatly appreciated <3. https://github.com/kawaii-ghost/futex-event

std::string a = "abc"; std::string b = std::move(a); Is move possible only because std::string implements a move constructor? Suppose if I create a custom type and don't implement a move constructor for it. Then does std::move by default will fall back to deep copying?

With rule of zero it will call its members move constuctor for each member

Otherwise if member does not have move it should copy

With rule of zero it will call its members move constuctor for each member

Suppose the members are primitive types, Do they support move using std::move or the actual rvalue is copied instead?

Move semantic is the shallow copy

For primitives it's the same

Thanks

In C++98 same effect as move was implemented with std::swap

You make an empty and swap with the one already containing data

Hence "move"

C++11 gave more robust and less boilerplate ways of doing it

I'm wondering why I don't see this often talked about and this is the first time I'm hearing this. From C++11 onwards, other than lvalue and rvalue, there are xvalue, prvalues, glvalues. Just started reading about this.

Cause I'm not a book, I'm a person and share MY understanding

Not a proper definition or whatever

So yeah I'm just doing less of "acshually ☝️🤓"

Because as useful as these things are to a language implementer or language lawyer, we kinda want normal people thinking about these from a point of simpler understanding. The technical terms are useful to library implementers and compiler developers but normal devs just learn tricks and patterns

To me atleast, C++ feels like one of those languages where you just can't always write efficient code without somewhat knowing about how the internals of the abstraction you're using works...

That's true for all languages

Especially for high level ones

You shitcode something then "why so slow"

And because you're like 50 abstractions removed from the machine you don't even know why and where it's slow

And complexity of the hardware, OS, VM, libraries, etc pile up so it's hard to decipher if you don't know where to look

As much as premature optimization is evil, coding with complete ignorance of the performance of things you're using might result in the complete rewrite in the end
