using namespace std;

string play(string p1, string p2) {

    if (p1 == "rock") {
       if (p2 == "rock") {

It's interpreted in the same sense as HTML is. The HTML interpreter takes a HTML file as input and generates a bunch of stuff to appear on your screen. The C interpreter takes a C source file as input and generates a bunch of stuff to write into an object file.

9th for 'monad' is another name for an object and funcfags are using OOP every day while being too dense to realize it

>>59804870
First for "compiled" is a subset of "interpreted"

>>59805017
Anything with dynamic dispatch is an object (including functions) and FP fags are perfectly fine with that especially considering its a much better framework than OOP.
Also monad isnt a thing, its a classification.

when I look at code it seems everyone has fancy notation for their variables. You see function variables with leading underscores and different acronyms defining different types.

Do all projects just have their own standards about variable naming or is there actually some community standard out there I should get familiar with?

>>59805017
Nice try, you clearly don't understand monads but are desperate to try to make OOP stay relevant.

PROTIP: if you have to water OOP down to the point that "everything is an object!!", then OOP doesn't mean anything at all.

>>59804915
Disgusting, define a type for rock/paper/scissors instead of using string everywhere.

New /dpt/ challenge: write a program that accepts arbitrary input, and reports whether the input is a monad.

>>59805075

The process of compiling is not called interpreting. A language is called "interpreted" if there is no intermediate step in the program's execution. That is to say, the source code is the program. A language is called "compiled" if the source code is used to create the program. So for instance, some object code or bytecode is generated, and that is what gets executed.

Is writing a lexer in C the ultimate beginner project? I just finished mine and I'm so proud of myself and I learned so much about pointers and file/stream handling.

>>59805155

First of all, you should be testing your program in a virtual machine before you test it on real hardware. Second of all, post your source. Maybe you shouldn't have your kernel be doing crazy things like turning off the fan and overclocking the CPU.

>>59805960
monads allow for linear ordering of dynamic effects
so you can think of them as an abstraction of procedures

>>59805983
explain more

>>59805994
e.g.

perform task a
THEN perform task b

the "THEN" bit is the linear ordering
or strict ordering, I may be using the wrong word

the dynamic part that makes an applicative into a monad, is bind or join
(join can be expressed in terms of bind)

join takes a (m (m a)) and gives back a (m a)
i.e., you have your abstract procedure that returns a new abstract procedure
the dynamic monadic part is that you can then jump into that new procedure, in the same context, while if it were just an applicative, you couldn't

the type parameter / generic bit is so you can return an arbitrary "result", e.g. (m Int) or (m ())

for something like the list monad, you can imagine each effect as being "fork". e.g.

do
  x <- [1,2] -- fork into two threads, in one x = 1, in the other x = 2
  ...

You /can/ do non-front end work but you dont want to.

why exactly do people call dynamically resizing arrays a 'vector'? Rust has it as Vec, C++ as vector, and Java even has a Vector class but not commonly used.

>>59806258
freeing an invalid pointer will result in a program crash (technically UB tho)

>>59806258
"Yes".
As in, if you pass it an invalid pointer (one not received from malloc or friends) or a pointer you've already freed, the behaviour is undefined, and the program will most likely crash.
free is not going to tell you about it, though.

>>59806258
>Can free(ptr) fail?
No, but it can cause your program to crash

What's the preferred method of error handling in C?

Like if I fail a malloc should I just exit or return some failed status and let the caller decide if it wants to exit or repeat the same until someone fixes it or exits?

>>I want to keep this in the same class but when i build i get build errors because it's expecting semicolons where there arent supposed to be

                // You now have the recipient's name.
            }
            return recipient;
    }

i put this at the top but i guess i did it wrong at the first line?

>>59806294
It really depends on what you're trying to do, and the nature of the error. Here is my take on it:
If your program is "one-shot" (does something, then exits), just exit immediately. Trying to fluff around fixing shit is probably a waste of time, and is needless code complexity.
If you program is interactive, try and pass your error back to your input/main loop, and just try again later.
If you are a library, always pass the error back to the user. It's pretty damn rude for a library to quit/crash the program without a good reason.

It really is. People talk about how easily C allows you to fuck up, but C++ is worse in my opinion. There's so much shit you can use and the implicit stuff really makes shooting yourself in the foot an easy task. I've moved to C for most of my efforts because of this. I'm scared of returning with C++14 and the future standard that's looming on the horizon.

Wow I just did an interview problem that blew me the fuck out.

You get the width and height of a matrix, and a list of coordinates. With this, you have to compute the distance to the farthest point in the matrix reachable from all the coordinates you were given.

At first it seemed straightforward. I made a simple breadth-first search; starting from each given coordinate, I simply explored all the neighbors until I hit the boundaries of the matrix. Took me a while to re-figure out breadth-first search though... It's been a while.

OK, so I have a matrix of distances for every given coordinate... So what now? The question asked for the furthest point in the matrix in relation to every single starting point, not just one of them...

What I did was: for every point, select the smallest distance amont those computed in the breadth-first search phase. That way, I get the smallest distance of the point to any of the given coordinates. From that new "integrated" matrix of distances, I thought I could simply select the largest; that must have been the furthest point.

That solution failed the given test cases though... I don't know why. I ran out of time and couldn't fiddle with the problem any longer.

Anyone know how to solve this? It's really bothering me.

>>59806577
"Effective Modern C++" seems like a lot of great info and it's scaring the hell out of me. I don't know if I trust C much over a restricted and reasonable subset of C++. I really tried to like Rust, for almost 6 years now since it looked really different. I know the language pretty well, but it's so goddamn unproductive and the ecosystem feels like I'm reinventing the rock.

Browser tech is pretty cool but don't fool yourself thinking that WASM isn't going to create a upheaval in the next 18 months. JS will never be stable or fast enough for many applications. Data analysis, games, audio and video manipulation, and new ways to consume information. The web is successful because it is 0-install and easy updating. The web could be more successful without a broken inheritance model, insane type-coercion semantics, and a generation of library gluers who can't prepend characters to a string.

Starting from the white tiles, compute the distance to the most distant point. The distance is calculated by moving horizontally and vertically (no diagonal movement).

You receive matrix size and the coordinates of the white tiles. For example:

7 5     # 7x5 matrix
2       # two white tiles
0 4     # white tile #1
4 3     # white tile #2

Output is the distance to the farthest tile:

5       # maximum distance

What I did was:

1. Depth-first search from each white tile, producing a matrix of distances from each white tile.
2. Iterate over those matrices, computing a new "integrated" matrix. The value for each point is equal to the smallest value for the same point among all matrices computed in (1).
3. Iterate over the "integrated" matrix, compute the absolute maximum value.

This algorithm computed 7 instead of 5 using the example above.

When I first read Effective C++, my mind was blown. The biggest, and most helpful, thing I learned from it was that C++ is more like a union of languages than just one. It made so much sense and allowed me to not only take a new approach with my C++ programing standards but that of others too. I have to say though, I don't know if I can take a another mind explosion from Effective, but I'm going to have to eventually to keep up.

>>59806998
Which language are you talking about? I can come up with at least 10 languages based on this syntax...

>>59806998

Argument vectors are a mistake. They're placed on the stack by the operating system, limiting how much data you can pass to the program. Many systems/terminals have additional arbitrary platform-specific limitations on top of that. There are so many switch styles and option-passing syntaxes it's amost impossible to deal with it in a sane way.

Use standard I/O streams for ALL program input, including configuration. Fuck Unix.

The furthest point will always be a corner. So check tiles in all 4 directions from each point, until you reach the edge of the matrix. Then do the same by going up/down or left/right. Sum the distance of these 2 steps and get the maximum outcome.

Not just me, the entire world is fucked and computing is now dead because nothing works.

swapfunc(a, b, n, swaptype)
    char *a, *b;
    int n, swaptype;
{
    if(swaptype <= 1)
        swapcode(long, a, b, n)
    else
        swapcode(char, a, b, n)
}

What a retarded definition, no wonder someone who speaks a mongrel dialect of English would think that. By your definition something which is at its core more simple (machine code) is somehow more complex than any high level language which compiles to it.
>A one to one mapping does not.
You don't seem to understand what "one to one mapping" even means. It's synonymous with compilation. Which means even the necessity for it clearly shows that it's merely an abstraction.

Not really. Higher level languages use compiler-level optimisations, which are, of course, compiler-specific. Therefore, the same C can map to many possible ASM outputs, as an example. ASM -> machine code translation is one to one on any compliant compiler.

Why would a programming language be exempt from meme status?
Also, calling lambda calculus a programming language just seems incorrect. Do you call a Turing number a programming language? Do you call second order logic a programming language?

>>59805164
Is Python interpreted? Python isn't run directly, the interpreter is essentially a stack machine and Python code is transformed into a sequence of op codes before being run, so by that definition it's not interpreted

>>59808738
Lambda calculus IS a programming language
With second order logic it's more context
You can directly translate second order logic into a typed lambda calculus (I forget which type system) and you'd call that a language

Even that is incorrect.

A compiler is, by definition, something which maps an input language to an output language. The necessity for this transformation shows that the language being compiled is merely a layer on top of something else.

Why would you even need to perform this translation if assembly was somehow already the lowest level language of that machine?

H*skell is a programming language (as you yourself admit), meaning it can't possibly be a "meme". I think you are referring to the memes surrounding H*skell, not the language itself.

I watched a yt tutorial how to create a simple snake game.
Now I used what I learned in that tutorial and decided to make a 'racer' game, as in you move your 'car' left to right on the bottom of the screen and have to avoid oncoming obstacles

so far I got this, it works, I can move the car, however I can't come up how to make it stop when it hit's the '#' wall
I mean I got the idea, but I dont really know when this piece of code should be

#include <iostream>
#include <conio.h>
#include <windows.h>
#include <ctime>

using namespace std;

const int width=20;
const int height=20;
bool gameOver;
int carX, carY;

enum eDirection{STOP=0,RIGHT, LEFT};
eDirection dir;

void setup()
{
    carX = width/2;
    carY = height-1;
    gameOver=false;
}

void draw()
{
    system("cls");
    for(int i = 0 ; i < height ; i++)
    {
        cout << '#';
        for(int j = 0 ; j < width - 2 ; j++)
        {
            if(i == carY && j == carX)
                cout << '@';
            else
                cout << ' ';
        }
        cout << '#' << endl;
    }

}

void input()
{
    if(_kbhit())
    {
        switch(_getch())
        {
        case 'a':
            dir = LEFT;
            break;
        case 'd':
            dir = RIGHT;
            break;


        }
    }
}

void logic()
{
    switch(dir)
    {
    case LEFT:
        carX--;
        break;
    case RIGHT:
        carX++;
        break;
    }
}

int main()
{
    setup();
    while(!gameOver)
    {
        draw();
        input();
        logic();
        Sleep(30);
    }
    return 0;
}

Exactly, there is no abstraction involved in assembly

So your processor directly executes assembly without translating it to machine code? Those are the only circumstances under which assembly would be considered a non-abstraction.

>>59808900
>Same reason why you can't understand Chinese moving pictures and need subtitles.
Speak for yourself.
If the machine can't understand assembly then it's obvious to any sane person that assembly isn't the language of that machine, meaning it's an abstraction.
>See >>59808738

I'm working with git for the first time, and I've already cloned the repository. I've made some changes to my version of the file and I did a pull and it told it was up to date. I added the file and made a commit and then I did a pull, it still told me everything was up to date. I did a push, the content on the online repository changed like it should, but what about conflict resolution?

>>59809099
>>59809109
To be fair, an abstracion is a way to generalize constructs and problems. Calling a nearly 1:1 mapping from assembly instructions to machine instructions is some hardcore autistic dictionary riding (i.e. argumentum ad verecundiam).

>>59809174

It really doesn't matter, the claim that assembly is somehow not an abstraction is outright false.

>>59809183
Prove it.

>>59809168
Git will let you merge changes in conflicting files, otherwise you just need to rebase when remote updates while you were working on local copy.

Most of the times this will suffice:
git pull --rebase

>>59808098
mips_asm

>>59809099
It doesn't, though.

>>59809109
Sure. "dec" really hides what the processor is actually doing, right? It doesn't just mean 0xCE to the processor, right? Heh

>>59809196
It's self-evident. No processor understands it, meaning you have to convert it to some lower-level form before execution.

>>59809216
The name "dec" is a convenient way for humans to remember the actual instruction, which is the very definition of being more high level.
It's pretty clear why you're acting this way, you think you have taken the true redpill by using assembly, but the ugly truth is that you have been fooled. I can only hope that you recover quickly and start using a real language instead of high-level garbage.

Machine code is also an abstraction (especially hexadecimal notation), what the cpu 'really' only understands are electrical signals - and even that is an abstraction over quantum phenomena.

It's abstractions all the way down.

>>59809217
I hope you realize that you're arguing that you're calling mathematical functions "abstractions" at this point, right?

>>59809206
>Git will let you merge changes in conflicting files
But how? It never told me my files differ from the ones on the remote repository.

>>59809262
In what way?

>>59809270
Oh, sorry, but does someone else beside me have to change the remote so that I would have something to pull?

>>59809270
If there weren't any conflicts, git can just seamlessly merge without problem.

Git stops the merge if there is a conflict, and you have to resolve it before you continue.

>>59809270
>But how? It never told me my files differ from the ones on the remote repository.
Some changes are non-conflicting and get fuzzed, in case of conflicting changes the editor will open and you will have both changes next to each other and it will let you pick which ones to keep.

>>59809291
Yes, if it's just you that makes the changes then there's nothing upstream that the local copy needs to be updated with.

Does gcc ever use mmx instructions? I'm doing something that should be easily possible with mmx but gcc just keeps operating on single bytes. It doesn't have any problems with sse though.

>>59809289
From Wikipedia, but any mathematics book will tell you the same:
> In mathematics, a function[1] is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
The important part for this discussion being:
>with the property that each input is related to exactly one output
Which means that any one (set of) inputs to a function must always produce the exact same result.

Unless you're using a hardware agnostic assembler (those *are* abstractions!), any hardware specific assembler will transform any line of assembly code to a specific output data. If the developer actually put any effort into the assembler (with regard to history: very unlikely) it might give you warnings or print errors if an assembler construct will be converted into an instruction that will cause a CPU exception without the user having to painfully figure that out on his or her own.
Nevertheless, a hardware specialized assembler is a direct 1:1 mapping of the assembly code to the resulting machine code, i.e. a function in the mathematical sense.

>>59809368
> It doesn't have any problems with sse
IIRC SSE is a superset of MMX.

>>59809359
It's pretty easy too. However, if you buy them they're usually much smaller and you can get a lot more functionality per m3.

Making tubes would be easier

>>59809377
>Nevertheless, a hardware specialized assembler is a direct 1:1 mapping of the assembly code to the resulting machine code, i.e. a function in the mathematical sense.
Yes, I understand that a compiler is indeed a function. Your point being?

>>59805454

>>59809406
No it's not. A compiler for a regular programming language may switch around instructions, replace instructions with precomputed results, ...

>>59805472
Who are you quoting?

>>59809428
I should have said a good compiler.

>>59809439
A good compiler is an optimizing one. Which does exactly what I said.

>>59809431
It quotes the post before, dumb robot.
>Who are you quoting?

>>59809443
A good compiler is something which is a function. What you described is merely a toy which shouldn't really be used.

>Let Σ be a non-empty finite set of symbols (alternatively called characters), called the alphabet. No assumption is made about the nature of the symbols. A string (or word) over Σ is any finite sequence of symbols from Σ.[2] For example, if Σ = {0, 1}, then 01011 is a string over Σ.
>The length of a string s is the number of symbols in s (the length of the sequence) and can be any non-negative integer; it is often denoted as |s|. The empty string is the unique string over Σ of length 0, and is denoted ε or λ.[2][3]
>The set of all strings over Σ of length n is denoted Σn. For example, if Σ = {0, 1}, then Σ2 = {00, 01, 10, 11}. Note that Σ0 = {ε} for any alphabet Σ.

Why all this formalisation is needed?

>>59809377
>>59809428
You're confusing the definition of function with the more specific 'monomorphism' (one-to-one function). You should be talking about those.
You can certainly argue that a compiler is a function, but not a monomorphism.

>>59809473
Without formalisation, you're going to have a pretty hard time proving anything to be correct.

I'm trying to insert some data inside a table via PHP, but looks like it's broken. Did I do something wrong?

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
