lua with C++ is comfier
you only have to export one symbol and you get curly braces

Yea but Lua is dead and has less libraries

>lua is dead
so is python, guido quit
>has less libraries
if you can write C++ you're not some niggerfaggot who need to import everything

Damn why didn't I use clang-format before now, it's so perfect holy shit

What's the best way to quickly develop programs on linux and make them work on windows?

Unironically electron

when will they finally optimise this shit?

Python is the language everyone now learns now in Uni (sadly) so it wont die probably ever unless people create something even more braindead

Like user said electron but if you could somehow use Visual Studio then for .Net-Core there is a framework called Avalonia that allows you to create multiplatform GUI apps using WPF, also isn't QT for Python and C++ multiplatform aswell?

What were you doing when cirno was kill?

You can in a regular loop
'foreach' is giving you a copy of the value so modifying it would do nothing

Hi, i'm learning cmake and I can't get this shit to work. I have a git repo of a library (cmakelists file below) and then I have another repo where I want to add the first one as submodule and use it as a static library
#generetared by clion
cmake_minimum_required(VERSION 3.14)
project(paretofront)
set(CMAKE_CXX_STANDARD 17)
add_library(paretofront pareto.cpp pareto.h)

i've tried many ways but I never seem to
to get it right. What should my cmakelists file look like in my main project?

Imagine being that inefficient

Probably read Marisa hentai.

you can do this in C++ c:

I have chosen C# as my first language!

use cmake subprojects
better yet, use meson

So I know C, python, have been using linux for years, have a good handle of the command line, bash, have several large personal projects, have basic knowledge regarding algorithms and data structures

But what do I need to do to actually get a job

C# should be your last choice. Ah yes, foreach is useless in C#
private static void Increase(int[] arr)
{
for (int i = 0; i < arr.Length; arr[i] = arr[i++] + 2) { }
}

You know python. Thats enough

Ok then wise guy, gimme something. And don't say Haskell or OCaml...

Learn JS and become web dev. Ez money bro.

C++

I am working on Android.
It already works on JNI wrappers and all of that did that months ago.
The issue is that we’ve told this Chinese model does not support JNI because “????”.

C# is a strange choice but it's a decent enough language.

Can I have recommendation on how to get started with embedded stuff?
My personal goal is to do some basic input output and simple linear algebra on an arm microcontroller.
I've bought a stm32 nucleo but the official getting started guide is windows "click here click there" stuff although the documentation says Linux is OK too.
But I'm lacking fundamentals since I don't know beyond "I need to compile and flash the hex file on the device".
Where can I find resources so I get a solid background knowledge?

Meanwhile in C++
[spoiler]for(auto &x : arr)

cool!

1. Get micro controller
2. Do the thing

C# is a pile of shit
* No `const` parameters
* SDK has opt-out telemetry
* No `Option` for reference types
* `MSTest` not portable
* Can't index arrays slices on multidimentional arrays
* Can't access a subarray in a multidimentional array with a given index

foreach (var val in arr) val += 2; // compile fails
for (int i = 0; i < arr.Length; arr[i] = arr[i++] + 2) { } // works

public void fn()
{
{
int x = 4;
}
int x = 3; // Considered Harmful
var a = String.Format("A {445}", "B");// 0 warnings, 0 errors
}

C# is good if you want to work, mostly because microshaft could sell business a shit stained dildo and they’d fucking buy it.
Oh do I hate (((Azure))).

I get stuck because of my lack of technical understanding.
So I'm taking a step back and ask where I can learn so that I know what I'm talking about when I go ahead and do the stuff

What's the best scripting language for linux? Guido hates white men

is web assembly actually any faster than javascript?
I'm always ready skeptical of these claims, because it's m it still runs in the same motherfucking virtual machine as js so how on earth can it be all that faster
plus it needs to be called inside of js anyway it seems like pretty niche use to begin with, but then you expect all these js babies to write coherent code in c++ to compile to webass, it seems like a lost cause

>4 traversals
yikes

Perl or Bash

>no arguments
Shut up

well i guess it's 3

just live in a faraday cage like from that nigger movie

Google it. 90% of the time some dipshit as
A) asked somewhere
B) made a guide
C) both of the above.

Set an objective, find how to do it, understand how it works, change it to fit your needs.

POSIX shell.

Perl is dead.

how is it that C++ has const correctness but none of its descendants do?

>No arguments
My argument is there, read again.
People need and want C# programmers more than C or C++, hence it’s a better market skill unless you have experience in programming already so you can try to land a cushy senior/mid level C/C++ job.
C# is good if you want to get a job. Same for JS, Swift, objc, java, etc...

its chromium so never
is like asking when will incels ever get laid
or is there a limit to how far sjw's can shove that stick up their bums

I don't

you can easily implement a foreach that returns the object by reference and not a copy. Stop crying

Im gonna make auto dabber in C.
so i can dab on zoom zoomies and their toy languages.

Lads do I just call it a night and convert to Rust or stay strong?

do so now then

don't listen to the shitters here. I started my career programming with C#. it's an excellent language. From there, you can learn C++ and many others. Start with C# user

do so now then

the javascript virtual machine is not the only target for wasm

>Perl is dead.
No it isn't

How did you go about learning Ada? I'm interested.

ive had this happen to me on nativescript(think react native but angular and by god was it slow) and despite each screen(page or whatever you want to call it) there were niche situations where doing something on some sub page caused some weird effect on a completely different page

it just seems to be what happens when your language becomes so abstracted, random shit happens for no discernible reason because the real problem is somewhere under hood that you can't debug

Sorry it's still Python. Time to take your tittie skittles user.

literally just copy the default foreach implementation and put a ref keyword.

It's probably just a language construct that's not replicated in the compiled representation (unless preferable).
It's too stupid even for Microsoft.

I remember this place is filled with morons and leave after a few amazing posts by CSneets and trannies.

Yeah, but Java is even worse than C#

Depends on your local market.
Mine looks for:
JS webdev>C#>Java Android>=Kotlin=Java BE>Swift/iOS.
But yes, generally java is good to know professionally specially with how hard has Android hit, making Kotlin also very desireable.

>best scripting language
C
Just wrap it in a conditional compile/call script that passes on all the parameters.
Using multiple languages hurt your intuitions.

I initially watched youtube.com/watch?v=0yXwnk8Cr0c which made me interested since the guy (RIP) was pretty interesting with the talk and information. I went through learn.adacore.com/courses/intro-to-ada/index.html which is really a super quick introduction and touches on everything and got me interested. After that I downloaded the Programming in Ada 2012 which is super comprehensive and will teach you everything. It can be pretty dense tho at times.

This is basically a super useful info dump for information and what's publicly out there: github.com/ohenley/awesome-ada

>>JAVA# BAD!

J# is good if you want to work, mostly because orcalel could sell business a shit stained dildo and they’d fucking buy it.

>Not making a COBOL controlled monster dispenser
Heh... zoom zoom.

Are you retarded? Being a wageslave language is literally the entire point of C# and Java, with the only difference being that Java has more jobs/larger ecosystem and C# being a bit less vomit inducing.

He said upset because he got called out on his complains being stupid.
>Inb4 some dude larping how he’ll get a high paying super super architect job out of the gate without ever having to wageslave monkey code

Mine is similar.
.NET ASP +SQL > .NET Desktop >Java > PHP > Swift > Javascript > C++

what the fuck is going on in this post

the companies that really pay well do not post job offers on the internet. They go to universities and take the best students once they finish the careers. At least it's how most important companies do that here

Yeah didn’t list .NET and all of that because I assumed it was implied on the C#.
I see no desktop shit tho, it’s all web on the c#/.NET.
JS is a lot of node.js and angular and ionic.

That’s mostly an American thing.
And if you have a company hiring you out of the gate for a tutoring basically I doubt that the opinion of anyone here is relevant on what to learn and that you should have better sources (ie your senior coworkers).

>C# being a bit less vomit inducing.
Myth. I used both of these.

I'm spanish and that's how serious companies do it here.

Also, what do job offers mean by "analyst"?

>Top 10
>no COBOL
I thought COBOL was a high paying job.

Attached: 1492983602929.png (800x689, 203K)

I am also Spanish and I’ve seen it happen once and mostly because the dude who got it (DB analyst) was actually paying attention to an optional lecture and became bff with the lecturer.
And even then he was paid pretty low until he was promoted.

COBOL devs aren’t paid in money, they only accept:
1. Gold
2. First borns

how do I add a std::tuple as a member of struct but with "generic" size? I don't want to restrict the size of the tuple.
