That's not a bad thing

whats wrong with my shitty c bit code it prints 0001110100 when i expect 0001101010

void printbits(int number){
    char lol[10] = "0000000000";
    for(int i = 0; i < 8; i++){
        if((number & (int)pow(i,2)) != 0){
            lol[i] = '1';
            
        }
        
        printf("%s\n",lol);
    }
}

C++ is a horrible language. It's made more horrible by the fact that substandard programmers use it.

Yeah, this one surprised me desu, andrei's protege was nice to listen to.

>>61634376
Namespaces are good, but modules and namespaces together are better.

>>61634282
Yes it is. The language looks promising in terms of syntax and what it can do but then that gets blown away because it has really poor debugging methods. Turns the language into a simple toy.

>>61634310
Debugging D is awful. There really is no standard "out of the box" way to debug code like in C or Java that just work. D has a random mix of debuggers that either do a poor job of debugging or can't debug at all. This really hold the language back in my opinion.

How do you dereference variables when calling commands in bash?

var="dicks"
output=$( some shit | awk '("$2" == "$var") { print $3 }' )

I did it using eval but I hear it's bad practice to use it.

Thats true i suppose. You might look into the Linux version of Coedit if you care enough. They have a nice front-end.

Ive found that taking a functional approach with D rarely has me needing a use beyond some sparse writeln though.

Np. You can also do

1 << i

, but your compiler will probably optimize that for you.

C++ implementation:

void printbits(int number){
  std::vector<bool> bits(8, false); // Vectors of bools are more space efficient in C++
  for (unsigned int i = 0; i < bits.size(); ++i){
    bits[i] = (number & (1 << i)); // Compiler warning for casting int into bool, but w/e
  }
  // Print result
  for (auto &b : bits){
    std::cout << b;
  }
  std::cout << '\n';
}

First question, why C#?

>>61634446
>Ive found that taking a functional approach with D rarely has me needing a use beyond some sparse writeln though.
It is a bit off putting though. Rolling with print statements is limiting vs procedural line by line examination of the logic. Why does it have to be this way...

>>61634449
But I don't want to create shitty code. I want a way to double check my logic and fix whats broken because I know I'm bound to fuck shit up.

I've finally got the supporting code in place for my Discord bot written in [spoiler] D [/spoiler].

You can define commands that match on patterns in the messages that users send by writing functions and tagging them with custom attributes in a separate module. You then pass that module name to a function that automatically imports your module, loops over all the declarations tagged with @Command or @Pattern and generates the code to look for the patterns you've defined. If your command isn't very complicated you don't even have to specify the pattern to look for; if you leave it out it will use the function name as the pattern. Writing a command is very simple:

@Command
string ping()
{
    return "pong";
}

@Command("press f to pay respects")
string payRespects()
{
    return "f :pray:";
}

import std.regex;

@Command(`(^say)\s+(.+)`)
string say(Captures!string captures)
{
    return captures[2];
}

I have to say that I really like how powerful D is. It seems like there's either a tool for everything you'd need or you can easily create one.

>>61634614
Code academy will give you a basic introduction to logic, which in your case is far more important.

>Why does it have to be this way...
Well VS Code + GDB + native D stacktracing work well enough.
If no one gets to it by then, its like the fourth thing down on my project list.
But you should definitely look into soft-functional in your language of choice. It really cuts back on a lot of debugging.

Well, I had special motivation for getting this to work as I wanted to write a bot that monitors a friend's twitter for new tweets and automatically posts them to a private discord channel so me and some friends can make fun of him (he thinks he's a big e-celeb and posts the gayest shit. He is also in this discord channel). This is just the discord side of things. I recently created a command that can scrape google for images as practice for scraping his twitter feed for tweets.

/dpt/ how do I use ADT to do trait?

Suppose I am writing game in pure functional language

I am need game object. One of few legitimate use case for object oriented programing

Simple enough just express object state as algebraic expression of types and create alias to said expression

BUT THEN!!!!!!!!!!!!

I am need something like inheritence in order to expressing many rich diversity of game object

Consider situation!:
Have the objects
* Some game object are solid
* Some are stationary
* Some are both but not all that either is both
* Some are control by player
* Some are UI abstraction
* Some are pickup to restore stat, endow ability, etc
* Some are enemy
* Some are walk on land
* Some are fly
* Some are siwm
* Some are affect of gravity and physic
* Some are have more simplerudimentary scheme of move
* ALL have many different overload for interactbehave! Behave are be construct from what?? From what list above!
* AND YET!!!!!!: ALL are game object!

Just because you're better than us doesn't justify you in being aggressive about it.
Maybe it's because we're exemplary of undesirable qualities you've strove to purge yourself of, and as rightfully proud as you are to have emerged victorious in this pursuit, you're still a bit viscerally jealous of the relative simplicity we enjoy in not bothering to strive as hard.

This is really the core sentiment of the point you're making here.
Now let me explain to you why it's misguided.
You're not good enough.
These people who are better than you, who aren't weak, they're good enough. They rightfully deserve basic consideration for their emotional needs.
You don't.
It's totally okay to vocally or even violently regard you with contempt or disgust for any reason or even for no reason at all. There's nothing morally wrong with that, because you are simply not good enough to deserve the contrary.

No problem. For future reference, when you Google expressions that contain words prefixed with hyphens, don't include the hyphens. On Google, a word prefixed with a hyphen is code for "only return pages excluding this word."

It's true though. C has variants, tuples, and type constructors, and they're all incredibly efficient. It even has monads, they're called pointers.

I already know FP. And I know Maybe is literally nothing but a type constructor whose instance may or may not wrap an instance of the parameter type.
>inb4 b--b--but muh pattern based overloading
C doesn't have that. It still has Maybe, just without that particular way of handling it. Granted, that particular way of handling it is the whole point of the construct, but it's also not a part of it, it's a part of the language.

You may have misread. What I said is that Maybe--that is, Maybe specifically, not monads in general--is just a type constructor whose instance may or may not wrap an instance of the parameter type.

>>61635826
Indeed they're not the same thing. Pointers are much more versatile.
But more specifically, a pointer which documentation guarantees is either null or valid and forbids taking the address of for any purpose but to test it for nullness is the same thing as a Maybe.
And the only difference there is documentation.

>>61636924
His shitpost is more understandable than the real thing desu.

The fact that C++ needs an auto keyword is proof the type system jumped the shark. There's no reason to even try to understand the type signature in C++. You just have to hope you memorized how to use it.

I'd rather use a dynamically typed language if I can't read the type signature.

>>61636992

That's true but it's also pre-expansion.

Depends on what you want to do.
Go is the simpler language and can be nice for concurrent network stuff. Downsides for most people are probably the error handling and missing generics.
Rust on the other hand has the more advanced type system, better C FFI and you can do basically anything you can do in C. The cognitive overhead while writing/learning Rust tends to be higher though.

>>61637499

The one you like, compilers are compiled into machine binaries anyways so the language probably wouldn't matter.


Also, Rust really could grab C++ by its balls. Because it's not burdened with

2. Piece of shit type system
