i have my mpz r= b06fae1faad9f8a004dc586a0d9dfadaf1dad8e3747583cc59b8c10bbd60ff5161f85e81e22d41244012f89b0a621b08 and do rigth shit of 224 bit. i use mpz_fdiv_q_2exp but i get this b06fae1faad9f8a004dc586a0d9dfadaf1dad8e3

Hermann

why it is wrong?

Hermann

i should get b0 6f ae 1f aa d9 f8 a0 04 dc 58 6a 0d 9d fa da f1 da d8 e3 74 75 83 cc 59 b8 c1 0b

Alex

does somebody know about malloc and linux lazy page allocation?

Alex

I mean pages can be not mapped after malloc is called

Can anyone help I need to start with c/c++ (I am student) I need courses can I get them on YouTube or else like Udemy Pls help

You're not going to get good with Udemy or YouTube. The University of Helsinki and Aalto University have created a C MOOC course together, I have not tried it, but I've heard the Java MOOC course by the University of Helsinki is excellent. https://moocfi.github.io/courses/2016/aalto-c/en/ You also of course need practice and practice on top of this MOOC.

Ok bro thanks Will try this now 👍

Guy

If so, I'm assuming the same exercise wouldn't work if the array was an int array, since it would try to multiply the array's address by four and add the index to jt

Network Level Authentication (NLA) information please?

Guy

Yes that's what I said?

Guy

Ah it's not

Guy

I just wanted to add to it

Is there a cleaner way to copy one container elements to another container of a different type in C++17 than using a loop and do manual push_back or insert? E.g. here from std::map I'm conditionally copying key elements to std::vector, but I feel there can be an algorithm for that https://pastebin.com/BTMZx9VY

Is there a way to check nginx status in c/c++ in ubuntu

Pavel

I looked at it but didn't understand how I can use it in this case

Pavel

thanks, that what I was looking for

Waiting for ranges...

You can use them in C++17 :)

Pavel

I have not the latest compilers supported, and I guess not all three: clang, gcc, msvc supporting ranges for C++17?

Google ranges-v3

It's the lib which was adopted to the standard

Pavel

Google ranges-v3

🤔 I thought there's a new C++ syntax for ranges

No It's just a lib

Pavel

Great, then I definitely need to check it

Btw, vector can be constructed through a pair of iterators or, if you already have one constructed, you can use the assign function, which takes a pair of iterators

Yes, but as I understand I can't take an iterator from a map (an iterator for keys for example) and use it in a vector. That would be a nice feature though

You can wrap an iterator in another iterator

Artöm

Hm that sounds like a library. Thanks for an idea

just use copy from algorithm and back_inserter

Alex

copy(component.begin(), component.end(), back_inserter(filtered.begin())

if you need condition, you can use copy_if the same way adding lambda for criteria

Thanks~

I guess that won't work as map and vector have different iterators

vec.insert(vec.end(), map_obj.begin(), map_obj.end())

It will work, for std::vector<std::pair<Key, Value>> and std::map<Key, Value>.

Liam

If you want to copy Value`s from `std::map<Key, Value> to std::vector<Value>, use std::for_each with [&vec] (std::pair<Key, Value>& pr) { vec.push_back{pr.second}; }.

Francisco

Btw, there's a proposal of an operator called pipeline-rewrite, which would release us from the heavy template machinery that ranges work on http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2011r1.html

Francisco

It's just a syntacti sugar, where x |> f(y) is just the equivalent to f(x, y), which is kind of similar to how range algorithms work

Francisco

If it gets accepted for C++23, many parts of the ranges library would get obsolete and probably deprecated in future releases

Francisco

Nice
