and C++'s standard library is not as common to find as one of C's several libc implementations

which is why you use C on rudimentary embedded systems

vinícius*

it'll likely have C on it, not necessarily C++

vinícius*

such as Arduinos, for example, they run a subset of C++ but don't have access to C++'s STL

yeah I'm talking about this

Y u do dis? (Please paste your code here or if it's long, post a hastebin.com link.)

oh. what's wrong in it?

you didn't look at the answer. it mentions that std::random_device can be deterministic. it also mentions how to use getrandom(), /dev/urandom, CryptGenRandom and a bunch of other solutions based on platform

Anonymous

ye it has solutions for BSD too

Anonymous

"There is one final caveat: modern OpenBSD does not have /dev/urandom. You should use getentropy instead."

Anonymous

followed by an example

Anonymous

oh

Anonymous

welp, idk openbsd

Anonymous

oh. then the bsd part of the answer might need correction. but the rest is fine, right?

Anonymous

what is the alternative for BSD though?

Anonymous

oof

Anonymous

oh @bsd > Reading random bits from random hardware devices. that didn't seem like the point of the question. it was basically "std::mt19937 mt(rd()); looks bad. how can i make it better and portable" and the answer provided a bunch of solutions mentioning that you need to depend on platform specific solutions.

Anonymous

i provided him the SO link because i was about to post std::mt19937 mt(rd()); in the next message

Anonymous

@first paragraph - no. my answer was suggesting random_device to seed mt19937 as an alternative of srand with time, and then mt19937 as an alternative of rand.

Anonymous

rand() is implementation defined though, and the C standard makes no guarantees about the quality of sequence produced.

Anonymous

Call getrandom()

Cry until it returns

MT is a standard algorithm but rand() can be anything, can't it?

software engineering is mostly about performance and scalability

vinícius*

learn data structures, classical algorithms

vinícius*

algorithm design & analysis, etc.

C will make you care about memory management which is a good thing

she takes the arguments

#include <vector> #include <iostream> auto PrintAny(auto&& Argument) { if constexpr (requires { Argument.begin(); }) for (auto&& x : Argument) std::cout << x << " "; else std::cout << Argument; std::cout << std::endl; } auto main()->int { PrintAny("hello"); PrintAny(2.71); PrintAny(std::vector{ 1, 2, 3, 4, 5 }); }

auto main()->int what is this kotlin

C++ since C++11 or 14 I suppose

It made me laugh

Take dem arguments girl

I'm starting to adopt that style in my code. Seems more natural to me

const auto v = std::vector {1, 2, 3}; ?

Ибраги́м

const auto v = std::vector {1, 2, 3}; ?

2017 FTW. std::vector v {1, 2, 3};

Ибраги́м

C++11

Yea, 14 made trailing return types optional in many cases

Francisco

const auto v = std::vector {1, 2, 3}; ?

You can do that. The thing is being consistent with the style you choose

Anonymous

You can do that. The thing is being consistent with the style you choose

Do you write it this way?

Francisco

I don't normally do it that way. Only in places where I don't really care about the exact type

Francisco

For example, I don't care what std::distance returns exactly, but I know it's going to be some integral type, so better use auto to ensure you get the best result

Alex

I use auto for iterators

vinícius*

same

vinícius*

I use auto when I don't want to type a long std variable name

In .vimrc If I want to add #include<stdio.h> to every file which i open via vi command Which command should i use? Is this possible?

also, if you're using linux, you can do a bash script for that: #!/bin/bash echo "#include <iostream>" >> $1.cpp && vim $1.cpp

Thank you

Yes, using linux

when you execute the script just type in the name of the file you want to create, for example: ./script hello Will create a file named "hello.cpp" and add "#include <iostream>" to it and you'll be inside of vim automatically, ready to write awesome programs
