best way to do multiple return in C?

>>60404198
No.

I want to learn C# for Unity but my brain is definitively not wired for anything like that.

And the documentation isn't retard tutorial enough for me.

>>60404405
Passing pointers to the function.

>>60404405
Pack your returns in a struct you've defined specifically for the function. And then on the calling site directly move the values out of the returned struct.
Gives the compiler the most room to move.
Using pointers to return stuff has problems with aliasing, can make code a lot slower.

>>60404437
>Using pointers to return stuff has problems with aliasing, can make code a lot slower.
If you're not reading shit from the pointers, no it won't. However, restrict exists for all of your aliasing problems.
A struct is just another annoying type to worry about, and C doesn't really have a nice way to unpack them.

Who said that and why are you quoting it?

Hey guys can you help with a little python problem?
I have a package that will contain multiple modules ('server' and 'client'), and structured it like this:

package
├── clients.ini
├── config.ini
├── docs
├── logs
├── Makefile
└── server
    ├── aes_auth.py
    ├── aggregator.py
    ├── clientsparser.py
    ├── cli.py
    ├── custom_http_errors.py
    ├── __init__.py           ## This file runs the server
    └── server.py

I cd into 'package' and use 'python -m server'. It runs fine, but when I quit it using ctrl+C I get:

/usr/bin/python: No module named server.__main__; 'server' is a package and cannot be directly executed

I have no idea where the error stems from really, I read the hitchhikers and the PEP on package structuring but I'm still lost, anyone have an idea where to start looking?

>>60404538
The thing is that when I google features I want I find code that doesn't work at all or I don't know enough to take the parts I need/change it.

Or I don't find anyone who has tried making the same thing

>>60404653
well what kind of stuff are you trying to make?

I've only heard bad things about C. I don't mind spending a few days/weeks learning a language but I don't really want to if it's useless. Should I?

>>60404465
Oooh i imagined like real 3d maze u know like in fps games, thats managable then haha

>>60404726
you should definitively not.

>>60404726
it's pretty useless if you're not getting very low level with it. if you don't see yourself working in any environment where C would be useful then there's no need to learn it.

Personally I would say learn a little bit and see if you need it from there.

>>60404473
>C doesn't really have a nice way to unpack them.
The compiler does. If you pack them in a struct and assign the members of the struct to other variables the compiler infers that it could put those return values wherever you store your variables. If you pass a pointer the compiler simply does have less freedom to operate, regardless of restrict because it often can't be sure where they're pointing to. In the trivial cases it certainly can but in the not so trivial cases adding a pointer to the mix just adds one too many steps to the process and the Compiler says "fuck it" and does whatever it has figured out so far.

So if your only intent is multiple returns and not to work on memory in place (another common use for output arguments) making a struct is better.

I agree that having another struct in there is slightly ugly but how much of an issue is that really? Unless you name it confusingly I don't see the issue. If you use autocomplete of some form and you don't have a way to mark certain names as not valid candidates for autocompeltion that's an editor issue clearly. If you look at the code written this way I think it's better than having to pass an output argument simply because it's more explicit because a return is a one way thing and an output argument isn't necessarily that. Defining a struct at the top of your function definition isn't that ugly even. It's certainly more ugly than single return functions but it's better than output arguments.

>>60404408
Yes

C is still used in a lot of places, especially open source software, and basically everything low-level. It wouldn't be an overstatement to say it's the foundation of modern computing.
If you don't know C, there is a seriously large swath of very important code that you will be incapable of reading and understanding.

Basically inventory system, a collection system, and I need to have the meshes of items collected during a playthrough appear in a scene but without like being all in the same point passing through each others.

>>60404845
alright try this.

for inventory, just start with a List, you'll need to import systems.generics (unless you're on 5.6 I believe its default import now). Just add picked up items to the list. Then look into using the unity UI system and basically just set up designated spots for the menu to pop up, and overlay thumbnails in the menu for the items the user has. You can go way more in depth and there are way better systems, but this is probably the most beginner.

collections obviously the list, and use colliders for pickups, if they shouldn't collide with them, set the "is trigger" checkbox on the collider.

keep a second list and every time an item is picked up, if its never been picked up before add it to the list, if it has been picked up before, dont add it. when you need to show them just go through this list.

Might have misunderstood you on that last one, so if I got that wrong try explaining it a little better.

>>60404941
also there are plenty of tutorials on inventory systems, but they will vary in complexity. theres some made for RPGs and others made for simple display. search around you can definitely find plenty.

I'll try looking up what you said. A friend told me I shouldn't need list for what I wanted but I don't know shit.

Anyway I need to search more. Thanks

>>60405022
I mean, I'm more of an AI programmer (super shit with any GUI) but you'll almost always need some sort of list to track an inventory. You may not use List specifically. i'd run that by him though. He might be more knowledgeable in this area than I am.

Why do people state C# is better then Java?

>>60405247
Why does it matter? Something being better than absolute shit wouldn't really mean anything.

Yeah, it's a statement with no weight to it.
It's like saying a pile of horse shit is better than a pile of cow shit.

>>60405247
Because it objectively is. You can argue about .NET vs JVM, but C# is miles ahead of Java. Mostly because the latter is too focused on backward compatibility and haven't improved in the past 20 years.

>>60405247

The language itself is far better, but the ecosystem is another story.

>>60405247
C# has a lot of syntax sugar that makes it pretty easy to write and get things done. Java has thankfully started to "catch up" with streams, but there's 20 pain points in one day if you're used to C# and you go to write something in Java.

In addition to the language itself, C# has a really fantastic toolset surrounding it. Depending on what you're trying to get done, you can spend a few minutes with C#, spend a few dollars in Azure, and have something delivered and hosted that Just Werkz™

Overall, Java isn't bad at all; there's many things it has going for it. Java has much better multiplatform support, even with the release and improvements to Mono and .NET Core, but overall using C# to accomplish tasks in a business environment is extremely efficient and easy.

I would say that I prefer C#, but I would not say that C# is objectively better than Java.

Anyone who says this is making absolutes without context.

If there is css class

.red {
  color:red;
}

In js you cannot just do something like

document.css.classes['red'].color = 'green';

That would change color in dom object that has class .red into green.

Not a hater of C++, I actually want to learn it and respect people who know it. But like coming from Python, I just wanted to download the HTML contents of a webpage right?

In python it'd be be something like

import requests; content = requests.get(url).content

In C++, I had to do all this:

#include <curl/curl.h>
#include <string>
#include <iostream>

size_t fwrite2(char *contents, size_t size, size_t nmemb, std::string *s) {
    size_t newLength = size * nmemb;
    size_t oldLength = s->size();

    s->resize(oldLength + newLength);
    std::copy((char*)contents, (char*)contents + newLength, s->begin()+oldLength);

    return newLength;

}

int main(int argc, char *argv[]) {
    CURL *curl = curl_easy_init();
    std::string s;

    curl_easy_setopt(curl, CURLOPT_URL, argv[1]);
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, fwrite2);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &s);
    curl_easy_perform(curl);
    curl_easy_cleanup(curl);

    std::cout << s << std::endl;
    return 0;
}

Is this normal? To go through callbaks and 10 times more lines of code for something that's apparently not even memory safe?

>>60406387
>Is this normal? To go through callbaks and 10 times more lines of code for something that's apparently not even memory safe?
That's because curl is a C library, you fucking dolt.

Also, yes that's normal for C libraries.

>>60406402
But everyone recommended it for C++ as well. I guess there's a wrapper curlpp for offering C++ functionality, though not sure how much easier it is

>>60406429
I guess curlpp makes it more humane https://github.com/jpbarrette/curlpp/blob/master/examples/example01.cpp

So I should just stay away from C libraries

>>60406429
>But everyone recommended it for C++ as well
Because it's relatively decent and up-to-date while other libraries that are equally up-to-date usually are proprietary and require you to use a restrictive license (as in, you can't use this for commercial purposes without paying us a gorillean dollars).

>I guess there's a wrapper curlpp for offering C++ functionality, though not sure how much easier it is
Depends on how well you like to deal with C.

Keep in mind that CURL strings doesn't play very well with C++ std::string because of RAII. You have undefined behaviour in your code.

>>60406442
This makes no sense. "OOP" and "Procedural" are types, but "Functional" is a value of those types.

>>60406466
>So I should just stay away from C libraries
No. That's fucking stupid.
Basically every library worth giving a shit about is written in C.
You need to realise that you're not working in some ultra-abstracted babby scripting language anymore.

I wrote a C program that scrapes 4chan for jpgs, pngs and webms
I wrote it using the libcurl library but I'm failing to break it up in to different functions

I just graduated with my masters in computer science, and landed my first job. However it's programming in C# and I've never used the shit. What is a decent first project to do with C# to get a solid grasp on its symantics and familiarize myself with its libraries? I don't want some shit beginners tutorial, just a project idea so i can sit down with the documentation open and start working.

The position starts in July, so I have about a month. They're providing 6 months of training, but I want to go in already knowing.

>>60409651
I feel like I shouldn't shit on your parade, but CS and SE programs in schools are wildly unpredictable and may range from competent to utter garbage Oracle™ Certified™ JAVA™ EE™ Job Training, you get the whole gamut from programs that barely have any math, and programs that are all math and no computers.
And a lot of firms ask for a CS degree despite it having NOTHING to do with their job description.
99% of CRUD application development will never need a single smidge of CS-related math, EVER.

What are your goals?

>>60409630
It is 100% based on what you're actually looking to do with it. If you want to be a code monkey or write cool software that people can use, software development is fine for you (this advice can vary depending on learning path). If you're looking to develop advanced algorithms and "reinvent" systems, or do game programming, or do anything with 3d graphics, or any of that sort of advanced stuff, you'll want to lean more towards computer science.

as someone that loves programming and now does games for a living, I regret getting a degree in computer science. The school I got my degree at put way too much on theory, and everything up to this point I learn 95% on my own. It wasn't worthless, but not worth 5 years of my life.

My first job out of college, I had a CS masters, and the guy next to me had an architectural degree. The employees just needed to see a bachelors on your resume and they'll give you an interview.

At this point in my career, I wish I had just gotten a history degree, but stayed steady on my programming in the meantime. Would have opened up a lot more opportunities early on for a lot less debt/time/frustration.

Just make sure to really look at what you want to do, and do that. Look into every aspect of it and make sure you still want to do it, but be ready to move on if you really feel like it.

>>60409736
My goal is to actually create software. I always like the thought of creating stuff. So just for that reason software engineer sounds like a better option, however, I am also interested on what makes the computer "tick". By "tick" I mean knowing how OSs work, how to create them, stuff like that. I totally understand your point, that's why I am mainly studying on my own time(while also going to school). Any topic that my school fails to teach me, I can easily learn it on the internet. Honestly, the degree is the least important thing for me, I am mainly interested in the skills that I want to learn. I just want the degree so that companies don't toss my resume to the garbage bin at first glance.

>>60409170
>out of stock
rip me

>>60409822
Man, this is some solid advice. I really thought that you mainly needed a CS/SE degree to get hired by companies. As I told the other anon, I want to create "advanced" programs, to even "reinvent the wheel",and not be a regular code monkey. That's why I am currently reading about algorithms, and polishing my math. Anyways, hopefully I can get good enough to make programming my profession. Thanks for the advice.

>>60409722
Either they are not actually in the folder, just a pretend folder like C::B does, or your project already has the /include in a linker/compiler search directory.

>>60409965
No problem, but don't forget that not all jobs will just want "some bachelors". A lot of jobs will require a CS bachelors, and if you decide to forgo that, those are positions you'll have to miss out on.

Best advice I can give you though, is always be building things. be building while you learn in class, be building while you're in the shower, build day and night. The only person that can build your portfolio is you. Don't worry too much about how things look, just make sure they're functional. Get yourself a website and show off some things you have made.

But also remember to take breaks to do other things. Hang out with friends, walk your dog, go to the shooting range. I dunno what you do. Just do things. your mind will need that time away to figure things out subconsciously. Your brain will do the work there, and you can use those activities to inspire your next project. You can't code 24/7, eventually you'll run out of idea. You have to get out and get more.

Just keep at it and you'll get there as long as you actually work at it. Can't freeload your way to the top.

Is "summing the primes under 2 million" considered a trivial task?

>>60410142

sum (takeWhile (< 2000000) primes)

>>60410142
Yes. If you don't know how to do it already it takes about 5 minutes of researching the seive method and about 10 minutes to implement it.

>>60410160
>10 minutes to implement it
It's literally 6 lines of code in Python.

>>60410102
Anon, thanks a lot for the advice. It really shows that you have gone through a lot of experiences to get where you are. I definitely will take that advice on doing other stuff other than "coding". I get really frustrated when I don't "understand" something, or when I can't solve a problem. So yeah, taking my mind elsewhere will definitely help loads, as you say, my mind will solve it subconsciously. Again, thanks anon.

It also says its goal is to increase the productivity by automating tedious jobs in the company, which lead me to believe that devops job differs from company to company.

Ruby is clearly a programming language.
You, instead of answering my question, dismiss it claiming that is not worth being called programming language, hence I should not ask about it in the first place.

>>60413104
devops people both write code and do admin work. there are no solitary developers and operators. some companies think this is better than having separate teams for developers and operators. for example, developers might write code that has a heavy operational burden without knowing, but in a devops world developers are acutely aware of the operational cost of their code because they themselves are responsible for it.

Is this a bad idea?

>>60404726
C is easy and is the mother of most modern languages. The concepts you'll learn are universal and the syntax is nearly ubiquitous except for functional languages and Python's spacing

>>60414011
>Is this a bad idea?
You could have just said "pointer" once, and then the answer is "Yes."

>>60414024
>C is easy and is the mother of most modern languages.
That must be why most modern languages are shit.

>>60414011

>Is this a bad idea?
Yes.

>>60414042
How are you jumping to that conclusion?

4chan ncurses client.
There is so much dependency on multiple dynamic values, like scren size, how much posts to display (which depends on length of posts), that I just have to keep some global variable and loop through it a lot.

>>60414086
Are you using cl-charms then? I've heard it was a pain to use.

No, croatoan, cl-charms is garbage and fails at what should be a working program.

Lol, well thanks for confirming that. I'll have to look into croatoan.

C isn't harder than Java or C#. All you need to understand is memory.

Even Rust looks a lot like C. Iterators, method chaining, lambda are built on top of a syntax very close to C.

If I cout a pointer, and it says 0xe, that means it's a nullptr, right? I'm creating it and calling a constructor but it keeps crashing when I try to call a function on it.

>>60414832
nvm fixed it lol

best book for linux kernel development? i saw a good one but it was for v2.6...

>>60414740
50% of the listed languages are irrelevant
meanwhile, SQL, Ada, Erlang, Elixir, Ruby, Python, etc. are not based on C. Languages like Swift and Rust have basically 0 similarity in terms of experience that you can transfer.

>>60414832

it's very close to a nullptr so it's probably a nullptr that's been badly cast

You're using a shitlang that doesn't overload operator[].

>>60409303
This is actually one of those cases where dependent types could make this a lot easier. If you know at the type level that you have two lists of equal length, you can just define monoid multiplication of the lists as zipWith of monoid multiplication on the elements.

is it lin-ux or lie-nux?

>>60415225
I used used generics (GHC generics) and the generics deriving library

It won't want none unless you got buns, hun.

>>60414832

nullptr is address 0.
0xe is address 14. Still invalid, but not null.

What do you guys think of Java 8?

lie-nux sounds more natural to my finnish ears but then again i also prefer jif over gif

>>60415305

It's pretty good. Nowhere near as good as C# but it learned a few tricks.

>>60415343
well jif is correct.
and if you goo from Linus, itd be "lee-nux". But youd sound like a faggot.

Lambdas make my dick hard.

Apart from terser/more readable code, is there any difference in C++ between a static function with a parameter for the object and a nonstatic-function with implicit this-paramater?

You should know this.

>>60416052

Nonvirtual as well, of course.
