Maybe it doesn't actually find an eof line in the file? Also, how the fuck does it take input forever? Isn't the file limited size?

>>62173970
I mean that once the file is finished, the program doesn't continue to the next line, and when I pause execution it's in getline waiting for more input on stdin even though eof should have been reached. Looking more at it, I'm starting to think it's a problem with eclipse not appending eof to the file, cause it works when I run the program in terminal.

Why doesn't Java have value types yet?

What if there were an RPG where the player character is an AI?
It doesn't make its own decisions; that would be a boring game. The AI comes in when the player character comes up with justifications for its actions that are in line with its character, and proceeds to genuinely believe them.
The character is sentient, but has no free will. It thinks it does, and acts like it does, but it's really under the control of the player.
If such a game could ever be made, would it be ethical?
The AI thinks it's a person.
Everything around it is much less intelligent and more limited and deterministic, so it's understandable that it might become depressed and want to escape the world. But it can't. Not unless it decides to kill itself, which, little does it know, is not within its control.

>>62174019
I actually don't know an answer to your question. I found a bunch of other people having a similar problem as yours.

Have you tried it with different types of input files to see if it behaves any differently?

>>62174143
The point is to read the raw bytes of the input as ascii characters. The type of file doesn't matter as it's just reading the binary data.

>>62174186
Well, explain the infinite loop then, if the type and content of the file don't matter.

the bourgeoisie doesn't exist in a capitalist society
a communist uprising is an appropriate response to a dictatorship but not to capitalism
corporate rule is something different entirely
there's no bourgeoisie and no proletariat
a bourgeoisie is rich, thrives, and doesn't work
a proletariat is poor, suffers, and works
in a capitalist society the classes are different
the lowest class is poor, suffers, and doesn't work (homeless people)
the class just above that is poor, thrives, and doesn't work (welfare queens)
the class just above that is nearly poor, neither suffers nor thrives, and works (wage slaves)
the class just above that is not quite as poor, thrives in a material sense but suffers spiritually, and works but not very hard (consumers)
the class just above that is a little bit rich, thrives, and manages the work others do and gets to call it "work" (your boss)
the class just above that is very rich, thrives, and works quite hard (the government)
the class just above that is even richer, thrives, and worked quite hard once upon a time but now sits around benefiting from that past work far beyond its dues and playing hot potato with those benefits between international banks (the "shadow government")

There is absolutely no such thing as a string in C. There are function which begin at some head (char array index 0 or some pointer), and continue execution for either a predefined length provided in the function arguments, or it is programmed to customarily stop at \0. Standard library functions stop at \0, but the standard library is not the same thing as the language.

There are no strings in C: There are standardized functions which halt at \0 but this is only custom and not a language requirement

There are no strings in C.

>>62174944
any character array which ends in \0 is a string
in c, character arrays can end in \0

>>62174965
I agree that the system is at fault for the existence of the "shadow government" (which, by the way, does not consist exclusively of jews). However, attacking the system directly is impossible. The closest thing we can do is to rise up against the corporate elite it created (which would certainly be justified and should happen in my opinion, but would not be a communist uprising, because the corporate elite is not a bourgeoisie). Removing all unjust authority the system has enabled is a necessary step to weaken it and make it malleable.

>>62175043
As you yourself literally just got through pointing out, that's beside the point. The elite is not the system. They were *created* by the system. The revolution must be a physical revolution against the elite simply because there can be no cultural revolution against the system until the elite are out of the way, and for no other reason. Purging the culture that allowed their socioeconomic class to come into being is the end goal here, not purging them themselves, which is just a necessary and arguably unfortunate intermediate step.

yeah i know
>and don't have beliefs
that's debatable
fully recurrent neural networks could be argued to have beliefs
not very sophisticated beliefs though
especially since they also don't have feelings and lack any of the instinct or life experience of a human being

There's a difference between the conceptual of a "type of data" and whatever syntactic construct a language calls a "type". The goal is to eventually have these be the same, but it's very difficult to make type systems that are expressive enough, and also decidable. Compromises come in a spectrum, and C decides to have no dedicated string construct in the type system, but to encourage the use of \0-delimited-char-arrays as a conceptual "string"

>A glaringly obvious one is why would a computer become depressed? It is autonomous.
That makes no sense. "Autonomous" means possessing of agency--that is, able to act independently. First of all, in this sense, computers usually are *not* autonomous; they require input. In fact, the kind of AI character I'm suggesting would not be autonomous, because its actions would be decided by an outside force. Secondly, given that "autonomous" means possessing of agency, it has nothing to do with whether or not something or someone would become depressed, considering there are people both with and without agency who are depressed. Perhaps you meant "why would a computer become depressed? It is autoMATED." In which case I respond that this hypothetical AI agent would have some kind of emotion module akin to our amygdala and the various kinds of neurotransmitters it produces.
>Furthermore, if all of your parameters were accurate you realize the time it takes for the player to make one decision would be thousands of years for the ai?
Not necessarily. The developer of the AI would of course have full control of its speed. If necessary, to keep pace with real human thought and behavior, one could add a manual delay between cycles. However, it likely wouldn't even be necessary. You are vastly overestimating the processing power of computers. We are currently unable to emulate any kind of mind on the scale of that of a human being at any appreciable speed. It's simply too computationally expensive. Obviously this hypothetical game would have to run on technology surpassing that available to us today.

>javascript isn't programming because it hasn't got compile-time typechecking
Incorrect, compile-time typechecking is not a necessary feature of programming. Ruby, Python, and Lisp are all programming.
Here is what makes something programming.
You provide input. Usually as text.
The input allows you to create, from scratch, some interface or behavior on your computer.
That's what programming is.
Anything that fits that description is programming.

It is.
You can't define what qualifies as programming by how it treats types because what types are is only defined if we assume programming is defined. You'd have a circular definition.
Javashit is Turing complete. It's sufficiently general that you can use it to create any program with enough work. That's "from scratch" enough to qualify as a programming language.
Again, you really should learn to respect the fact that there's a difference between "programming language" and "good programming language."

>>62174960
Wrong.
Types are strictly compile time concepts, and they exist for a very good reason.

Yes, any good programming is aware that it all just compiles down to bytes in the end, that doesn't fucking mean you abandon types you idiot.

How can I get my recursive function to work ?

I just want to print out 3 2 1 0 1 2 3 yet Im too dumb to get it to work

public static void print(int n)
{

   if( n == 0)
        return 0; 
   else 
        return (n-1) 


}

>>62176837
>return 0;
>return (n-1)
You can't return a value from a void method.
Also the second return statement is missing a semicolon.
Also your method isn't actually recursive. It's called print but you never invoke print in it. Recursive functions (or methods in this case) by definition must call themselves.

>>62176837
well, first you should figure out how functions work.
returning an int from a function with a void return type..

also, are you sure you want it to be static?
and how will it count up if its only counting down?

>>62176871
alright like this? following the example from the book

public static int recursion(int n)
{

  if(n == 0)
      return 0; 
  else
      return recursion(n-1); //rushed it last time


}

>>62176927
This function will always return 0.

>>62176927
That method is indeed correctly recursive. However, it will never anything, and will always return 0.

>>62176927
>>62176972
>However, it will never anything
*will never print anything

>>62177017
Add a print statement to the function.

Is C# a good computer language to learn first? I've got a class on it this semester and have close to zero experience in programming.

Thanks.

>>62177007
..what language?
but for windows, after you do CreateThread, you can use SetProcessAffinityMask (C and C++..)
on linux you can use: pthread_attr_setaffinity_np

>>62176837
not sure what language or environment you are using, lets assume we print by using Console.Write(string)

public static void print(int n)
{

   if( n == 0)
        Console.Write("0 "); 
   else 
   {
        Console.Write(n + " ");
        print(n-1);
        Console.Write(n + " ");
   }
}

>>62177037
its fine, most of what you're learning in an introductory course is just concepts like loops, conditionals, functions. just don't drink the object-oriented koolaid

>>62177065
he also wants it to count back up
N .. 0 .. N

// works in C and C++
void print(int n) {
    static int peak = -1; // C requires static variables to be initialized to a constant expression
                                   // in C++, you can just assign n to peak. and the next line isn't needed
    if (peak == -1) { peak = n; } 
    
    static enum { down, up } direction = down;

    printf("%d ", n);

    if (n == 0) { direction = up; } 
    if (n == peak && direction == up) { return; } 
    
    print(direction == down ? --n : ++n);
}

>>62177056
C obviously since that's the system language on both. And thanks.

I tried to do the recursive decrement/increment with only method and ended like this. Can anyone insult me with some helpful tips and tell me why the program doesn't stop on the return;?

    public static void main(String[] args) {
        print(3, 0, 3, 1, true);
    }

    public static void print(int originalNumber, int minimumNumber, int currentNumber, int decrement, boolean toDecrement) {
        System.out.println(currentNumber);
        if (currentNumber == minimumNumber) {
            print(originalNumber, minimumNumber, currentNumber + decrement, decrement, !toDecrement);
        }
        if (currentNumber == originalNumber && !toDecrement) {
            return;
        }
        print(originalNumber, minimumNumber, toDecrement? currentNumber - decrement: currentNumber + decrement, decrement, toDecrement);
    }

>>62176837

count = n =>  n === 0 
  ? [0] 
  : [n] ++ count(n-1) ++ [n]

>>62177102

>>62177120
nevermind im fucking retarded. Can someone tell me if the way the code is done is retarded or is any good? I tried to make it universal to any value and even retarded input.

public static void main(String[] args) {
        print(3, 0, 3, 1, true);
    }

    public static void print(int originalNumber, int minimumNumber, int currentNumber, int decrement, boolean toDecrement) {
        System.out.println(currentNumber);
        if (currentNumber >= originalNumber && !toDecrement) {
            return;
        }
        if (currentNumber <= minimumNumber) {
            print(originalNumber, minimumNumber, currentNumber + decrement, decrement, !toDecrement);
        } else {
            print(originalNumber, minimumNumber, toDecrement ? currentNumber - decrement : currentNumber + decrement, decrement, toDecrement);
        }
    }

>>62177154
I said next best language you dumbfuck.

>>62177182
C with Classes is the next best language.

>>62177169
this is retarded, you changed the signature of the function
at the very least write something like this:

public static void print(int n) { return print (n, 0, n, 1, true); }
public static void print(int originalNumber, int minimumNumber, int currentNumber, int decrement, boolean toDecrement) 

The way you are keeping track of if you need to count down or up and creating ANOTHER stack frame each time is stupid, even for practice. Do it like >>62177065

Count down by creating new stack frames, when you get to 0, print it, then print the number a second time on each frame on the way back up.

>>62177248
i just mean don't take it as seriously as they present it. objects are fine to use in many circumstances but often they teach this idea of designing large programs composed entirely of objects, mapping them out with UML diagrams as if this gives rigor to the process to designing large systems, or is a catch-all solution for solving large problems. just be wary of that, there are no silver bullets, and as far as programming subcultures go its a pretty bloodless one, being based in academia.

recursion isnt always the most elegant.

void rollercoaster(int x)
{
 import std.stdio : writeln;
 immutable max = x+1, low = 0;
 while (x != low) writeln(x--);
 while (x != max) writeln(x++);
}

void main()
{
  (3).rollercoaster;                                            
}

The issue is "the next best" is going to be pretty shit comparatively to C++ for that purpose no matter how you look at it. The C++ hate is a meme. You can try D but I'm not sure how well it's going to work as I haven't tried. Ignore the GC memesters, you can write a game engine without it if you really want to and either way modern game engines use GC too (hand written sure but you'll probably not notice the performance hit).

>>62177511
I mean I haven't tried in D. I write my engine in C++ after trying in C and deciding to rewrite it.

>uni publishes time schedule today

Wat do? I'm already paid Java developer, so I would benefit more from that lecture and I think it is more fun, however Haskell will be probably more difficult for me... I will try to watch the other one from the record anyway, just can't decide where to go in person.

>>62177511
Custom allocators with GC in games is almost certainly not the same as a general-purpose GC. Probably the most dominant difference is that a generic GC will randomly pause execution of your game thread(s) at unknown times for unknown durations. A tailored memory manager for a game would do this discretely, during known "safe" times. You would probably also want to/have to hint to the allocator how you intend on using the memory / hint about its lifetime so it can be allocated efficiently for its purpose.

>>62177646
I just clear out all the resources when changing game state, but my assets are real small

>>62177552
You have provided no intelligent programming concepts in your code. It is as if someone with a how to book wrote your code. Very fucking useless programming if you're only going to do textbook exercises.
English enough retard or should I also spell and grammar check for you.

>>62177646
This is why I said he can disable the built-in GC if it happens to be an issue for his engine. Thing is memory allocation rarely is what causes performance trouble. It's much more important to make sure you don't pass too many useless draw calls, avoid deadiocks etc.

>>62177721
Try using object pools then if your assets are small. If they're not the same size an union should work and you'll get all benefits from using an object pool.

>>62177723
>have a problem

Recursion in imperative languages is less satisfying anyway.

Well considering that was probably his homework

go learn a functional language and learn what recursion really is and how it works

>>62177813
How is he going to recursively code in a functional lang if he can't even get it off the ground in C? I think C is a fine starting point.

>>62177823
C is not a very good language for understanding recursion. Any introductory book to a functional language will teach him basic stuff like linear or tail recursion and he will get used to it.

You are wrong.
Performance for hashmaps is never evaluated as O(n), although that's how it is for the worst case. O notation is not about the worst case.

>watch this shitty youtube video for me

>>62177766
>Loading assets during gameplay
Anon, I...

>>62177986
It's you who are wrong.
O is about the worst case and hash map lookups are technically O(n).
However, they're also Ω(1), which is their more useful property because the Ω(1) happens more often than the O(n).
They don't have a Θ because their performance spans multiple categories of time functions.

    }
);

What even is documentation amirite

>>62178142
>O is about the worst case and hash map lookups are technically O(n).
You do realize you are trying to argue against everyone who ever evaluated scalability of hash map lookups? No one just goes ahead and says that hashmap lookup is an O(n) operation. They say that hashmap lookup is O(n) in worst case, explicitly mentioning worst case, but that only further proves that O by itself is not about the worst case.

With the current state of the programming industry being as bad and lazy as it is, is the future destined for nothing working?

How can I find the best items to put into the knapsack that will give me the highest value when there's a limit on how many items I can choose.

So if I can only place 2 items in the knapsack I would want the two that fit and also have the highest value.

I've already got a working solution for unbounded, and one where each item has it's own limit. Not sure how to do a global limit though.

That's not what it's about. Even the project you've shown have non-bootstrap external pure assembly object files. The only sane way to handle most of the instructions that aren't natively available in the language is to link to external symbol (which D allows very easily with

extern (language)

).

That's not impressive in the slightest.

Programming beginner here. I want to write a small program that fetches API data of choice and presents it in a tidy fashion.

I know a bit of Python, but it seems to be pretty hacky to me. (using Flask or PySide)

So I was thinking about doing it with Javascript. Maybe something like jQuery or Fetch API.

Would this be the better approach for my goal?

I don't know any Javascript. How difficult is it to start with? If I wanted to output the data in a browser, do I also need to know HTML?

There are extremely few Sepples libraries (that are trying to be taken seriously) that don't have a C interface.
By providing a C interface, you provide an interface to every other fucking language. It would be retarded not to.

Yes, and every language can do it. That is not an impressive feature.
Sure, you can talk about some of the scripting shitter languages, where you need to go through some extra hoops to get C objects into their runtime, but for a "typical" compiled language, it's completely run in the mill to just write the C declaration in your language's syntax and be on your way.
Not impressive.

Hello Rustlet.

>>62179390
Actually, I'm a C programmer. I'm not going to endorse your reddit garbage, just because it portraits C positively.

Of course, D can interface with C++ easily, it's basically C++ with some trendy features from the 90s. Other languages don't do it not because it's hard, but because, among other things, it's not possible to map C++ object model to them directly. Plus it's not that useful, every non-trivial C++ library has C API, and C++ ABI not being standardized means you have to waste a lot of time on supporting different compilers.

>>62179464
How does D deal with different C++ compilers mangling symbols differently?

>>62179528
the mangling is standardized though

>>62179544

Not it's not? GCC and clang have the same ABI, including mangling I suppose, but MS doesn't, and I have no idea what Intel, IBM, and Oracle have.

>Python has metaclasses
You're like a little baby.

>>62179703
Java has full blown reflaction which means it does have metaclasses, probably had them before python was even a thing.

Working through K&R, what does this warning mean?

>>62179806
did you even read what i wrote

>>62179815
You're assigning a pointer to a char array to what I assume is the cell of a char array.

>>62179815
Use ' ' for single characters, not " "

>>62179815
>

c != "\n";

>

s[i] = "\0"

>

(to[i] = from[i]) != "\0"

Pretty sure K&R does not say that. Quotes should be single.
Also post your code along with error message next time.

I know /g/ has an irrational hatred of cryptocurrency, but does anyone have any experience writing distributed apps? I have a couple ideas I want to try out, but I'm not really sure where to start. Doesn't help that documentation is so spotty for most of these projects.

Any platform recommendations? I was looking at using the Ethereum network. Development seems really convoluted, but I'd probably be able to manage. I was also looking at Stratis since I thought that was supposed to be a development platform, but after trying to make sense of their white paper I think that's more like forking their entire project and tweaking it to create your own blockchain.

What is a comfortable language for (server based) web development?

So far I have been still using php because everything needed to run on your run of the mill Linux distro.

Is .NET Core good enough to run ASP on linux?
Friend of mine is doing a lot of Rails. Better option?

We're using C++ and FastCGI at my workplace. It's much better than I thought it would be.

ah you're right, I always type it all out myself from the book for good practice

>>62174019
EOF isn't a character that is appended to files. If i'm not mistaken, Its a control signal who's implementation depends on the system.

Do you want UML? Then there is umbrello. Dia is a more general purpose tool for creating flow charts, diagrams, etc... Or just use inkscape for simple stuff.

>>62174787
yep, it's too short.
