I was told to create "my own class library", for a very specific task.

What would be a good style to do it? Create a folder of its own, with classes? Something else to consider?

desu it looks messier than pure erlang

>>58076402
it means you put all the code in a single (header) file
this way if someone else wants to use your library they only need to include one file into their project

mkay. i thought the style convention is to have a file for every class, but that sounds reasonable.

Ok, fuck...
AGAIN.

We are STILL getting errors!

This wxWidgets is making me lose my fucking mind!

But hell, we're down to only 1 error!
Maybe someone can help with this last one and get me up and running?

Please? It's been 5 hours since I did my LAST (4th) rebuild of this fucking library...

||=== Build: Debug in testHello (compiler: GNU GCC Compiler) ===|
ld.exe||cannot find -lwxmsw30u|
||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 5 second(s)) ===|

JUST THAT (hopefully)
What do I need to do to get THAT to work?

>>58076460
>le omg how do i link a library?!?!?!?!
What the hell are they teaching kids these days.

>>58076460
you're asking it to look for a library called wxmsw30u
but it can't be found
make sure it exists and is in a folder which you have told it to include

>>58076460

This means that there is no libwxmsw30u anywhere in the linker's search path. You need to find the WxWidgets library files (should have a file extension of .a, .so, or .dll), and copy them into whatever folder ld is searching from. Alternatively, you need to use the -L option to tell ld to add a directory to its search path.

I'm building a collection of basic image filters in C.

Everything works fine, but I was wondering if there's a better way than a basic double for loop to iterate through all the pixels.

>>58076669
I don't know the answer but I'm wondering how you loop through the pixels?

>>58076694
>how you loop through the pixels?
Nested for loop (height, width). You get the RGB values for that pixel.

Then, for each pixel, you take its neighbors by a kernel and you add those values to the original pixel.

Each filters has it's own kernel, so basically the kernel for a intense blur is :

int    kernel[5*5] = {
        0, 0, 1, 0, 0,
        0, 1, 1, 1, 0,
        1, 1, 1, 1, 1,
        0, 1, 1, 1, 0,
        0, 0, 1, 0, 0
};

So... any ideas on this? Why does it say all of these are undefined?

I'm including the libraries. But, even when I comment out the libraries, it shows the exact same number of errors... As if including the big include file doesn't mean shit...

>>58076849

I'm a fucking moron and still can't get past these linker errors.

>>58077394
>exceptions
I don't know much about them but they're just error messages essentially right? So why would you care about having error messages if they're not relevant to your program?

Also a more general question:
How can C++ have exceptions if 'you don't pay for what you don't use'. Surely exceptions would be a feature that creeps all over the program as long as they're somewhere? How else could they run up the stack and destroy objects like that?

every time i read "using namespace std" that reminds me how glad i am that i ditched c++ for java.

such a cancerous line.

>>58077431

Sadly, it's one of the few languages that actually allow you to do things easily, efficiently and without tons of uneccesary mental model overhead that comes with most abstractions.

C++ is similar in that but only when you use certain subsets.

>>58077438

Annoys the living crap out of me that they did that.
I need to find some motivation but it's not like java programs don't have exit status.

>>58077453
>allow you to do things easily, efficiently
no, not at all. everything in C is tedious, boresome, errors prone. Try to implement a generic dictionary in C, for example.

>>58077465

If that means changing main.cpp to look like this, it doesn't work.:

#include <iostream>
using namespace std;

int main()
{
    whatPage = 0;
    while (whatPage == 0)
    {

    }
    while (whatPage == 1)
    {
        Game();

>try to do pointless high level construct in C
Yeah well if your use case aligns well with python or something like that then you can of course use python.
C and other languages that promises or care for performance are not for doing stuff that would be completely bonkers in that field.

I wouldn't ask a python programmer to try and do intrinsics well. It's just not what they are supposed to do.

Languages shouldn't be as general as they are honestly. They should have more specific use cases. PHP and JS are good examples of that. They're not good languages but they are where they are because of how they work in their own area.

what is the go-to file structure, if I want to create a list of custom objects?

i have no clue how I will use them - yet.

>>58077546
>try to do pointless high level construct in C
not pointless at all. ever heard of json or xml? do you have any experience outside of cs101 assignments?

>>58077553
What do you mean?

>>58077565
>have you ever heard of inefficient ways of storing data in text
I've heard of plenty of ways of doing that yes. But again, not the way you go about things if you want speed.

In C you'd have a clear input boundary where you take the JSON (hopefully you don't even need to take JSON), translate it into something for proper ladies and then work with it. If it absolutely has to go back to JSON then I could say you probably didn't choose the right language.

And C++ doesn't really do much better.

As if that's a good way to go about things.

>>58077635
Because its easy to understand. You'd probably feel just the same about LUA if that's where you started.

>>58077706
are you retarded? something like

json j2 = {
  {"pi", 3.141},
  {"happy", true},
  {"name", "Niels"},
  {"nothing", nullptr},
  {"answer", {
    {"everything", 42}
  }},
  {"list", {1, 0, 2}},
  {"object", {
    {"currency", "USD"},
    {"value", 42.99}
  }}
};

or

// create object from string literal
json j = "{ \"happy\": true, \"pi\": 3.141 }"_json;

// or even nicer with a raw string literal
auto j2 = R"(
  {
    "happy": true,
    "pi": 3.141
  }
)"_json;

// or explicitly
auto j3 = json::parse("{ \"happy\": true, \"pi\": 3.141 }");

is light years ahead of what you could do with standard C.

Again. This toxic perspective. Hopefully you will grow out of it.

As an aside if you're declaring a lot of json in your programming language you're probably doing something horribly wrong. Seems like a very problematic environment to work in.

Why wouldn't you just keep a couple json files on disk and parse them? Instead of having it all littered throughout your code.

It is not.
Also he's critique was not on OOP(that is also shit for that matter), it was on c++. Contrary to what illiterate fucks like you might think, c++ is not c with objects. It wouldn't even make sense to create a c with objects, since you can do OOP in c.

If I program C and use clang extensions how much do I hurt portability?
I don't really care if you can only compile with clang but it can compile to every relevant platform right?

I have to extract the data out of these and make it into "company" objects.

is there a reason to use arraylists over arrays, if i know the maximum number of entrys already?

>>58078500

You should always use raw arrays unless you can't

i have been told that lists are useful, if i want arrays of unlimited length.

>>58078523
Generally, no, unless you want to make use of the nifty utility functions that generally come with arraylist types.

not an argument.

>>58078631
The problem is that Python is very different from C, C++, C#, and Java, mostly in syntax and typing, as well as that it's a scripting language.

You can easily move from C# to Java, or vice versa. Even C/C++ have very similar syntaxes and typing rules.

Python is the ugly duckling here, and tends to be harder to come from into these other 4 languages that are easily the most popular non-Javascript languages.

>>58078647

because the object type is "words". the lexicon may or may not provide synonyms, up to 4, for each word.

a word may or may not have synonyms, and i wonder whether to handle the synonyms of a word as arraylist or array [4].

>>58078646
His sample has spaces inside fields as well.

He's probably best off writing a regex with groups for every field.

>The problem is that Python is very different from C, C++, C#, and Java
so what?
problem solving skils are far more important than the language you're learning.

that is how I intended to do it.
i just wondered whether there is a more "pro" method.

>>58078689

is this very bad, performance wise?
if the file has 4000 objects, the computer has to apply a very complex regex 4000 times.

>>58078658

Don't worry about performance before it's an actual problem.

>>58078701

>>58078567
Python

>>58078670
Sounds like the length of the collection is variable, so the easiest type for the collection would be one that has a variable size, thus something like an arraylist.

That seems more elegant to me than always having an array of size 4 with a variable amount of null values in it, and then having to do nullchecks and such.

    }

>>58078797
>Java
>Elegant

Yeah, you could do this really elegantly in other languages, but I wouldn't go for that.

If you have to do it in Java, make it work, then you can go back and try to make it "pretty".

Look for a CSV library that will do the heavy-lifting for you.

Alternatively, read line by line and split on a tab character, sorting the information into the respective classes.

Looks like you'll need two classes. One for each "header", and one for the multiple entries under each "header".

>>58078746
Do you need to separate the names too?
You'd probably want to split manually then.

Otherwise, I'd say a nice regex with named groups would be the best way.
Regex (without fancy stuff like look-behinds) is very quick if it's implemented properly.

>>58078797
just read the file line by line and parse each line

>>58078827
No, and there never will be.
That's general faggotry.
Nobody will agree.

>>58078827
No, because we agree on basically nothing. It's up to you to properly enunciate what you desire, and then cross-reference the responses you get from us with your own research.

What are you looking for?

Because that varies wildly based on what language you want to learn, and more importantly what you actually want to do.

see, each object is descripted in MULTIPLE lines.

like,

color of object 1
price of object 1
name of object 2
second name of object 2
color of object 2
price of object 2
name of object 3
color of object 3

so i have to define where an object ands and where it begins manually.

>>58078900
>limiting yourself to one language

>>58078892
You can use Java's String split method (but I think that actually uses regex too).

Or just read character by character, filling up a buffer, and copy the buffer to the respective variable once you hit a space,...

>>58078900

anon, but knowing only haskell really isnt practicable.

>>58078937

does that make for a better performance?
in comparison to regex for whole lines?

    {

That's the beauty of knowing C# or Java; if you know one, you can probably almost copy/paste the other and tweak to language-specific things.

For what its worth, I made two structs just to get the object-like thing ready, and doing it like this nests the locales as a list of structs within the Substance struct. You could do proper object, though:

public struct Substance
{
    public string Id;
    public string casCode;
    public string euIndexCode;
    public string einecsCode;
    public bool gadslClassDeclarationDuty;
    public bool gadslClassUnwanted;
    public bool gadslClassProhobited;
    public bool isReach;
    public bool isDeleted;
    public bool isHidden;

It was easier for me to type it right next to the method I was quickly hacking out.

There are other considerations between structs/classes, but in this case, I like to call the data structure a POO, or "plain ol' object".

It's easier to change access level and datatype when you don't use character-saving bullshit like that.

In the same regard, I virtually never forego brackets on something like an if-statement, even if it's only one line.

>>58079170
Keep in mind that this line is using C#'s LINQ (

.First(x => ...)

, so you'll have to find whatever lambda syntax Java has to duplicate it.

I honestly would go about this a very different way, but I'm not sure what the Java way is, so I made it very basic.

>>58079190
Java has streams, which are a somewhat shitty version of C# LINQs.

i will try to tweak the code in a way so I can implement

>substances.First(x => x.Id == items[1]).locales.Add(new SubstanceLocale()

Here's what I would normally do in C# if I wasn't worried about nesting the locales:

static void ReadSubstancesFromFile(string path)
{
    var input = ReadAllLines(path).Select(x => x.Split('\t')).GroupBy(x => x[0]);
    var substances = input.First(x => x.Key == "R").Select(x => new Substance()
    {
        Id = x[0],
        casCode = x[1]
        // ...
        // assign Substance properties with values from each "R" line
    });
    var substanceLocales = input.First(x => x.Key == "RN").Select(x => new SubstanceLocale()
    {
        Id = x[0]
        // ...
        // assign SubstanceLocale properties with values from each "RN" line
    });
}

This gives me

IEnumerable

collections that have delayed execution, so they don't do work until I query them for a particular subset of items.

why are you demonstrating what you would do in c#, if he was writing in java all the time?

About 75% through my second React Native app.

Just got a non-profit to sponsor the app for a cool 8k (I'm only rebranding, and anything in the future they want from me we'll have to sign another contract).

Right now I'm
1) Implementing a badge/achievement system
2) Further fleshing out reporting/hiding/blocking user actions (making sure you can unblock someone/asking you `are you sure?`
3) Cleaning up Android styling.

The badging system is likely to take some time.

The app has Microsoft's Code Push in place so I'll only have to submit to the App Store/Play Store once. This is gold compared to the Xamarin development I have done in the past.

>>58079341
because C# and java are very similar

should be programming but feeling lazy. will probably take today off ;-;

>>58079338
It's just a personal (bad) habit.

I default to 'x' on all LINQ blocks, because they're generally short and wouldn't benefit all that much from meaningful names. You already know you're working with each element in a given collection, and you can just mouseover the x to see the type if you're working on it.

You could always give a short name like 'line' or 'substance', and it could really help someone reading your code after the fact.

>>58079341
Wanted to demonstrate that even though C# and Java are very similar, basic language features can greatly change the average person's approach to a problem.

Some technical things:

The app doesn't have a server. I'm using Firebase for storage/database. Although, Firebase is a great service, this has been a huge limitation. I am not likely to be using Firebase in the future, as I don't believe it's production ready (being limited to one `where` clause per query). Pagination has been a pain, a lot of work-arounds require storing data in two locations in the JSON schema.

Everything has been made with ES7 specs. Async/await/etc. The code makes me a feel like a Medium Blogger Cool Kid ™

Only downside is having to wait for them all to download but then again most threads either don't have lots of webms so the additional data isn't an issue, or they have lots of webms most of which I want to watch anyway.

    unsigned long i = 2;

            sum += i;

        ++i;
    }

    printf("sum: %lu\n", sum);
    return 0;

}


char isPrime(unsigned long n)
{
    if(n <= 1)
        return 0;
    else if(n <= 3)
        return 1;
    else if((n%2 == 0) || (n%3 == 0))
        return 0;
    unsigned long i = 5;
    while(i*i <= n)
    {
        if((n%i == 0) || (n%(i+2) == 0))
            return 0;

try { 
            BufferedReader infile = new BufferedReader (new FileReader(filepath)); 
            infile.close(); 
        }

            System.out.println("Could not read " + filepath + ".\nPossibly, it is not a text file?\n"); 
        }
        

Is this the right order?
It seems strange to me to catch an exception in this way, because the second line (close) can have exceptions of its own.

>>58079552
No,

infile.close()

must be in the finally block. It's up to you what to do with the exception close throws.

>>58079552
put the close() call in a finally block

Can someone explain REST to an idiot?

>>58079455
you don't need an extra script for that:

curl 4chanthread | grep -E -o "//is.4chan.org/[a-z0-9]+/[0-9]+\.webm" | uniq | sed 's/^/https:/' | xargs mpv

>>58079549
Wut? I think I know a solution, just think about it.

>>58079583
I would just read that shitty grid into an array and then test every fuckin combination. Can't make up any other good solution

>>58079032
you don't need a bigint since the maximum value of the product is 9^13 = 2^41 < 2^64 - 1
you can just treat the 1000 digit number as a string and iterate over it lol

>>58079597
PROTIP: the diagonals are your arrays to test.

For example, you'll have:
08
91, 00
77, 62, 65
...

Then sort them by largest numbers and grab the first 4 elements from each jagged array of numbers

its the next ones that get hard. you can brute force 1-11 quite easily after that it requires optimzation.

Oh.
Yeah, I figured it was possible to do this way but I'm more comfortable with Python than with bash for now so that's what I used.

How so? I didn't run it to test but I doubt the language and implementation will have much of an impact on the run time, since most of it is spent just downloading the actual files.

my advice is get top left to bottom right, top right to bottom left, bottom left to top right, bottom right to top left.

then teh horizontal and vertical then just use your algorithm from the 1000 digit product like it was challenge 8 i think to solve from there.

>>58079158
Is "it's a meme" your only argument? Sorry for having read PLT literature from praised computer scientist like William Cook or Luca Cardelli. You should definitively read Object-oriented programming versus abstract data types from Cook or A theory of Objects from Cardelli to fill your lack of knowledge on the subject.

Each class should, for the most part, have their own header file. You should have a another header file that includes the header files of the classes like so:

foo.h -- class foo
bar.h -- class bar
my_library.h -- #includes the library headers, foo.h and bar.h

#include "my_library"

int main()
{
Foo foo;
Bar bar;
// do stuff
return 0;
}

>>58079843

curl 4chanthread | grep -E -o "https://is.4chan.org/[a-z0-9].......
