ok now you're halfway there. just missing templates, generic code and many other compile time features, to reduce runtime

Who need it i don't 😁 being a low level guy over here.

Don't mess here

:)

where to find

In the source code

Who need it i don't 😁 being a low level guy over here.

+

Ya but I got this https://github.com/gcc-mirror/gcc/tree/master/libstdc%2B%2B-v3

where in there?

where in there?

Find the file where it is

What more to say

wanted a string class implementation code

I don't know how to do that

kindly help

In which folder will that be?

Who need it i don't 😁 being a low level guy over here.

and "low level guys" like not having their code being generic and prefer to have the overhaed of doing all checks that could be done at compile time at runtime?

weird but ok

In which folder will that be?

src/string.cpp, but it won't be as simple as copying the file

Rust, Haskell, golang, haxe, Swift, C#

I wouldn't say C# is a good example. It wasn't available for linux over years

src/string.cpp, but it won't be as simple as copying the file

No string.cpp here

No string.cpp here

well that's for libcxx. if you're looking at libstdc++ then idk

I just wanted string class implementation code

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.

and nothing else. Where ca I get it?

I just wanted string class implementation code

And I would like a nice dinner

I just wanted string class implementation code

well write it yourself

Aah !! But I guess I made someone upset

sorry

guys

guys

Its okay, you will get there eventually

I got it.

But the reason I was asking is

that

which data-member of the string class holds the text when we write

string s = "abcd";

that's it

because naturally "abcd" is of type const char*

correct me on this if im wrong

that's implementation-defined, but you can use std::string::data to get a pointer to it.

but editing the memory referenced by that pointer is undefined behavior

but I guess the standard implementation must have used some pointer to "abcd".

Is that so?

https://github.com/llvm-mirror/libcxx/blob/master/src/string.cpp Searching "data" shows nothing.

Searching "data" shows nothing.

here

but I guess the standard implementation must have used some pointer to "abcd".

yes and you can get that pointer by calling std::string::data

Searching "data" shows nothing.

i told you that it won't be as simle as copying the file

it doesn't contain the whole definition or implementation of the class

what are you trying to do?

Is any text enclosed in "" double quotes const char*?

Is any text enclosed in "" double quotes const char*?

depends. why?

just wait a bit getting back to u in a sec

https://www.youtube.com/watch?v=Rr1NX1lH3oE

because in this video 3:24

he says "Cherno" is not a std::string but it is const char array

So any text enclosed in double quotes is const char array

and not std::string

yes that's true

My bad I was speaking const char*

So that's what I

m asking

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

"Abcd" is just chars in memory

So its const char*

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

that's implementation-defined

I'm not understanding ur meaning of implementation defined

you can get a pointer to that with std::string::data

I'm not understanding ur meaning of implementation defined

it's up to the library implementors to decide

I hope that the cpp developers use a standard library

the standard doesn't define it and you can't be sure

you can get a pointer to that with std::string::data

Could i use auto for this ? Or it needs to be used with cast ?

Could i use auto for this ? Or it needs to be used with cast ?

yeah why not?

yeah why not?

with static_cast ?

So its const char*

I guess he said it is const char array and not const char*

with static_cast ?

just use auto. don't see why it wouldn't work

I guess he said it is const char array and not const char*

Its the same

just use auto. don't see why it wouldn't work

idk, it's just a guess of mine) didn't use auto for this)

Although I have learnt that array do decay to pointers but they r not the same

better to use smart pointers

Could i use auto for this ? Or it needs to be used with cast ?

You can

the standard doesn't define it and you can't be sure

Didn't understand what u mean by "the stand. doesn't define it..." and why can't I be sure?

Now this is getting completely over my head

Didn't understand what u mean by "the stand. doesn't define it..." and why can't I be sure?

well because the library implementors can choose how to store the string and you can't be sure because there are many standard libraries and they have all choose diffrent ways of storing the data
