Sir Can you help in Networking
Probably, But I don't think this is the right place to ask, since this is for c/c++ discussion. We can talk in the offtopic chat

Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is.
These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot?
If you have a question ask it directly. You are more likely to get a response that way.

I am creating a weather forecasting app in c .. I want to it be multithreaded... so if I used posix library to create threads do I need to know whether the threads created by library by user threads or kernel threads?

I'm assuming you're running your code on Linux; in that case the answer would be both. Linux uses one-to-one model when it comes to userspace threads. You'll have a kthread per each user thread, and it all happens when pthread_create calls the clone syscall for you. However it's not that critical to know this when you're designing a weather forecasting app. 🤷♂ Just use pthread and you should be fine. (It's not a green thread, if that's what you're worrying about)

What is the exact or official release date of CPP,
Many websites have different release dates, that's 1981, 1983, and 1985.

first spec was released in 98 (according wiki)

Is there a difference between the two below lines in C++
test("ABC", "NBC");
test(string("ABC"), string("NBC"));

mhmm there may be a catch. if test is not overloaded for type const char * (which is type of "ABC") will compiler do implicit coversion of const char* to std::string ? if so the there is no difference

There is a difference.
for the test("ABC", "NBC"), your string is either in rodata or text section which means it lives in your binary file (ELF or PE). I'll send a pic below to show what I mean by that. That's why they're immutable.
For the test(std::string("ABC"), std::string("NBC")); your string is on heap (and your code section... but this is just a must for string literals... so it doesn't matter). Therefore, it lives in a different memory region.
Note: Implicit conversion won't happen if you pass a std::string instead of a const char*... you need to use the data() or c_str() method to return a pointer to your string.

uh I can't send images. nice. nevermind.

Agree but for test(std::string, std::string); implicit conversion happens right?

check the assembly code.
mov QWORD PTR [rsp], rax
mov DWORD PTR [rsp+16], 1145258561
mov QWORD PTR [rsp+8], 4
=>
1145258561 = 0x44434241 (little endian machine = "ABCD")
In other words, it is in code section AND heap. It should be the same as test(std::string("ABCD")). So yeah. it really depends on the test definition.

I added another call of test with explicit conversion and it looks the same (to me 😁) https://godbolt.org/z/GrE9f83rv (I have bad feeling we killed poor osm)

Yeah they look the same. It makes sense actually. The only thing that osmㅤㅤㅤㅤㅤㅤ needs to keep in mind is that string literals (no matter how or where you're passing them) will be in your code section first, then your constructor (here std::string) will decide to do whatever it wants to do with it. Make the string literal larger, and you will see that it only adds a label for it and puts it there for you. Still it's in your code section.
