I'm not an OOP purist, by any means. You can stop pretending that I am at any time.

Composition over inheritance has already been widely-accepted even in the OOverse. It's very easy to show that any example of a good class hierarchy using inheritance will break as soon as you go against the grain. This is a claim that I'm willing to back up, given some examples to work with. It's not contrived, at all.

It's well-known that you shouldn't use inheritance unless you can guarantee that your plans won't change, which of course is a bit of a pipe dream if you're writing real-world software which is ironically where you people say OOP is best.

They are so desperate that they'll insist it's still OOP

This is what I meant by calling modern OOP "C with classes".
That's literally what it is.
They're hanging on by a fucking thread, by methods alone.
If you got rid of methods, making all functions free, it would literally be a non OOP language.

C++ even nearly killed of methods with proposals for changing . 's behaviour.

>>56823484
>Composition over inheritance
Literally only ever a problem in OOP land.

Users of non-OOP languages are still wondering what the fuck OOP users are even talking about

OOP = POO

>>56823541
Yes

You're not cool for having written something in assembly code

>>56823607
Changing it so that it also works with surrounding functions in the same scope, i.e.

myfun(X a,T b, S c);

struct {...} x;

x.myfun(b,c)
=
myfun(&x,b,c)

Which is also how methods actually work, by passing *this as the first parameter

>>56823647
I'm saying that, much like design patterns, composition vs inheritance is only an issue in OOP. Other paradigms are not so crippled.

>>56823652
whoops,
myfun should take an X* as the first param
struct X {...} x;

>>56823652

That's essentially what Rust's method syntax achieves.

Not remotely. Haskell has a function (&) in Data.Function that does this
x & f = f x

anti-OOP memers usually have this strawman argument that you have to write pajeet-tier enterprise code for something to be considered OOP. you can make FP look ridiculous in the same way with haskell tards but FP on its own without taking it to its extremes makes sense too.

>>56823695

>>56824107

Yes.

>thinking in terms of paradigms instead of just writing good code with everything that is available to you

>>56824107
I'd argue that the encapsulation of state and methods together is inherently bad.

>>56824129
paradigms describe how good code is to be written

>>56824135
No, they describe a particular way to write code regardless of whether it is good or not.

>>56824134
not an argument.

>>56824134

You would argue that.

>>56824141
Why would a paradigm be popular if it inherently produces bad code?

What does "bad code" mean?

>>56824150
I don't know, anon, but that is clearly the case. Maybe not inherently, but in practice.

If I wanted to compute the seasonal variance of a player, would I have to compute each weekly performance, or is there a way to compute it from his overall seasonal performance?

>>56824156
most programmers are shit, but that's not the fault of the paradigm

>>56824147
Right, I said I would argue for that view. I didn't actually give an argument.

Encapsulation is useless with a good type system, because you can simply encode the invariants in types.

Simply hiding implementation details to allow them to change without the code that uses them caring is not really encapsulation and is still really easy to do without OOP (you just need modules, translation units, etc.)

>>56824184
It is pointless to have a type system because any type system that can cover all use cases is Turing-complete and therefore undecidable.

>>56824190
"not an argument" wasn't contributing. It was pointing out something that was already self-evident to anyone who can read.

The post you were responding to was in reference to the question "Are any of these things fundamentally bad?", which does not ask why anything is bad, only if.

>>56824260
Is it worth to live if in NJ?

>>56824223
Why does it have to be all or nothing? If my type system covers 99% of my code, it doesn't matter because it doesn't cover 100%?

this doesn't look reminiscent of anything to you?

>>56824223

Instead of giving programmers the tools to solve problems it (supposedly) solves the problem of managers replacing said programmers with cargo cult pattern-pajeets.

Okay.

Is this the best way to either update or add in Java? Seems pretty wasteful but trying to use a set didn't seem to work at all.

public void addItemToOrder(OrderItemModel orderItem) {
        for (int i = 0; i < order.size(); i++) {
            OrderItemModel addedItem = order.get(i);
            if (addedItem.equals(orderItem)) {
                addedItem.setQuantity(addedItem.getQuantity() + orderItem.getQuantity());
                order.set(i, addedItem);
                return;
            }
        }
        order.add(orderItem);
}

I think you could probably hack a script together with echo (I think CMD echo can do append?), and run it to download an arbitrary file.
Install a keylogger, write a script to allow you to upload more complex programs and fuck with him

I'm learning C at the moment but the third exercise of the chapter kills me. Since yesterday I have no idea how I can accomplish it. The output files are always garbage but I don't know how to solve it.

http://hastebin.com/okezuwuqod.pl

Exercise 14-3: Write a program that reads a file containing a list of numbers, and then writes two files, one with all numbers divisible by three and another containing all the other numbers.

    int filein, filein_size, numbers[100];
    char content[100], buffer[100], numbers_divisible[100], numbers_others[100];
    
    filein = open(argv[1], O_RDONLY); // Open the user given file
    filein_size = read(filein, content, sizeof(content));
    
    int i = 0, buff_cntr = 0, current_number = 0, number_index_di = 0, number_index_ot = 0;
    
    while(content[i] != '\0') {
        if(content[i] != '\n') {
            buffer[buff_cntr] = content[i];
            buff_cntr++;
        }
        else {
            sscanf(buffer, "%d", &current_number);
            
            if((current_number % 3) == 0) {
                numbers_divisible[number_index_di] = buffer;
                numbers_divisible[number_index_di+]
            }
            else 
                numbers_others[number_index_ot] = buffer;
            
            buff_cntr = 0;
        }
        i++;
    }
    
    int fileout;
    fileout = open(argv[2], O_WRONLY);
    write(fileout, numbers_divisible, filein_size);
       
    return 0;
}

I'm sure Java has some form of RTTI (real time type information), but i don't remember how to do that.

FizzBuzz with files.

Do you know how to read a file?
Do you know how to write a file?

Start with a program that just reads the numbers from the input file.
Then write a program that writes numbers, any numbers, to an output file.
Then combine those to read numbers from one file and write the numbers to another file.
Then it should be trivial to add another output file and branching output.

}
