bcz I don't have any knowledge of how these are defined and all the developer stuff

what data-member of string class is the "abcd" getting assigned

Sorry for a noob question : but who are the library implementors? R they the cpp developers?

People who write hod for std libs

They are

no they are people who write standard libraries. there are many standard libraries and everyone can write one.

popular ones are the MSVC standard library, libcxx and libstdc++

libcxx is core-maintained by marshal clow and loius dionne

no they are people who write standard libraries. there are many standard libraries and everyone can write one.

But if anyone can write a standard lib, then who decides whether it is exactly following the CPP STANDARDS laid down by the developers?

and if anyone can define them then is there must be some chance of faulty implementation

1. why caps? 2. if you decide to use a specific library you know whether it does or doesn't comply

obviously all the major ones do

the std-commitee decides whether you are allowed to call your compiler a c++ compliant compiler

👍🏿

if you market yourself as a cpp compiler without talking to them, chances are, that you get sued

If they wrote the kernel on it, it would be available from the box. The reason the kernel is not rewritten in C++ not because C++ is worser than C. You usually do not rewrite projects just because there's a new language. Otherwise we would constantly rewrite our code.

You're right. The kernel is not the topic of this conversation. The topic of the conversation is that guy who doesn't know which language he should start off. Over years, people think of C as a programming language which provides basics of knowledge about *programming world*. That is, if one learnt C, there would be no problem for them (maybe tiny ones only) to jump into JavaScript or PHP, and the same with C++ - the question is just codestyle as far as I get it. There's meaning called "C-like syntax".

this one helped me understand how it works. Thanx brother

np. you just need to understand, that the commitee is a loose stucture that works democratically. anyone can attend the meetings, anyone can vote in some, but not in all issues

i don't think you would if you claim being compliant with a specific draft and not the official release

to vote for the final std you need to be a bodymember of a country that works in the iso

what data-member of string class is the "abcd" getting assigned

libstdc++ https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/include/bits/basic_string.h#L166-L175

i don't think you would if you claim being compliant with a specific draft and not the official release

well,... we could argue about that, i am sure. thing is: everybody may write a cpp compiler, but if you want to sell it, using a trademark, make sure to talk to the people about it before selling it ;)

libstdc++ https://github.com/gcc-mirror/gcc/blob/master/libstdc%2B%2B-v3/include/bits/basic_string.h#L166-L175

So this is diff from the one you sent earlier

but,... if you are able to write your own std-complient compiler, you probably already know most people from the std-commitee

But if anyone can write a standard lib, then who decides whether it is exactly following the CPP STANDARDS laid down by the developers?

Implementation clsims some level of support, users check if it's documented, file bugs etc

btw, if anyone wants to attend the next std meeting. its in two weeks in cologne ;)

So this is diff from the one you sent earlier

Because standard doesn't say "string must have these fields", it says "it must have following functionality"

Aah now I get it.

Can I put it like "MSVC is one of the standard CPP library" ?

Can I get any response??

Can I put it like "MSVC is one of the standard CPP library" ?

msvs is a compiler

They use dirkumware std, which is c++ std lib (one of)

libcxx

?

Can I get any response??

Can you just wait? It's not like you're entitled to get one as soon as you post your question

One from clang/llvm, also std lib

diff b/w cland and llvm

?

Formulate question properly

clang is the c/c++ compiler llvm is the compilerproject, that also builds other compilers

so the compilers name is CLANG

diff b/w cland and llvm

Clang compiles to special language, then llvm compiles from it to asm

Formulate question properly

Can I say that "libcxx as a standard CPP library"?

Yep

libcxx is one of three major implementations of the cpp std library

clang is the c/c++ compiler llvm is the compilerproject, that also builds other compilers

And what is a compilerproject?

And what is a compilerproject?

a bunch of people that created a framework to build compilers for different languages

libcxx is one of three major implementations of the cpp std library

libcxx, libstdc++ and ? 3rd one

Dirkumware

In msvc

you can build different frontends for llvm, that get compiled into an abstract syntax tree which then gets compiled to asm

You seem to understand and explain things well to a NOOB.

well... i try my best ;)

ir, not ast

ir, not ast

ahh yeah,... you are right

intermediate language

fail^^

Ajay not abstract syntax tree

How do I link DLL file in vscode

@Bjoekel Does LLVM works in tandem with clang

@Bjoekel Does LLVM works in tandem with clang

wat?

I framed it really badly.

CLANG is a user-frontend to LLVM

CLANG parses C++ into an intermediate language.

LLVM compiles this IL to asm

as I said, you could also have other LLVM frontends

Like ?

can you name others

https://llvm.org/

for example there seems to be a rust compiler on top of llvm

Like ?

Like other languages

there definitly is a GO compiler on top of llvm

funny, I just saw that there is a LLVM ir -> javascript compiler :D

this should be burned alive i guess

So the job of LLVM is to convert IL to ASM.

yep.

IL or as some say IR, intermediate representation
