FizzBuzz!!

#include <stdio.h>

int main(void)
{
    for (unsigned long long i = 0; i < 4294967295; i++)
    {
      if (i % 3 == 0 && i % 5 == 0)
        printf("FizzBuzz\n");
      else if (i % 3 == 0)
        printf("Fizz\n");
      else if (i % 5 == 0)
        printf("Buzz\n");
      else
        printf("Hitler didn't do anything wrong\n");
    }
}

What are my nimfriends working on?

static void Main(string[] args)
{
    for(int i = 0; i<=9999; i++)
    {
        if(i % 3 == 0 && i % 5 == 0) Console.Write("FizzBuzz"); 
        else if(i % 3 == 0) Console.Write("Fizz");

        else Console.Write(i); 
        Console.Write(", ");
    }
    Console.ReadKey();
}

Basically identical, here's one in LINQ for some flavour

static void Main(string[] args)
{
    Enumerable.Range(1, 100).Select(
                            n =>
                            (n % 15 == 0) ? "FizzBuzz" :
                            (n % 3 == 0) ? "Fizz" :
                            (n % 5 == 0) ? "Buzz" :
                            n.ToString())
                            .ToList()
                            .ForEach(Console.WriteLine);

Or mention something about womyn in one of your projects, it'll get tons of attention.

>>52882704
critiqued in what way? there are pretty clear heuristics that you can use to assess how your profile looks to others:
- do you have activity?
- do you have interesting projects?

stuff like that.

it's not quite like a resume/CV where you can make a lot of design choices.

>>52882876
yeah but you don't really need me to tell you that caveating your profile with that is a sign of immense weakness, right?

You should be able to "red team" yourself at this level. Pretend you're a stranger coming to this profile and think about reasons that you would criticize this profile. You see like 2 days of *any* activity, and the first thought, reasonably, is that this is a nominal gitlab page. Even a generous viewer will see this and assume that your activity is somewhere else, but they can't reasonably assume how much or of what quality.

You shouldn't bother to publicize your github/gitlab page until there's something worth showing. Even if you don't have much activity, but you have a few projects that are sort of interesting and worth checking out, that would be enough.

But there's none of that here.

What are you workin' on?

Threadly reminder that for is a distinct construct with its own semantics, very different than while's.
This:

#include <iostream>
using std::cout;

int main() {
  int i = 0;
  while(i < 5) {
    cout << i+1 << "\n";
    continue;
    i++;
  }
  cout << "done\n";
}

loops forever while this:

#include <iostream>
using std::cout;

int main() {
  for(int i = 0; i < 5; i++) {
    cout << i+1 << "\n";
    continue;
    cout << "never reached\n";
  }
  cout << "done\n";
}

is fine.

How do I find a project to do?

int search (int array[10], int elem, int size) {
    int i;
    int pos;
    for (i = 0; i < size; i++) {
        if (array[i] == elem) {
            pos = i;
            return(pos);
        }
    }
       return(-1);
 }

hey guys, my search function returns -1 if there is no occurrence, and it returns the index if it is present. But how do I make it return all the indexes if there is more than one occurence?

Have it take another parameter called StartPos, and then you could do something like:

int i = 0;

while((i = search(arr, 25, 10, i) != -1)
{
    //do a thing!
}

            lel[++count] = i

Any ideas how I can get the time out of the time I'm being handed by 4chan api?

My method of manually cutting it up and then convertiing it to a DateTime using DateTime.ParseExact doesn't seem to work for all boards because of the inconsistent way they handle it.

>>52883865
Oh never mind, just read the documentation properly, some boards don't give you the seconds, I'll have to just write a method for handling it.

>>52883850

Just because it says arr[10], there really is no requirement that it has 10 elements.

Reposting. Feel free to ignore me if I'm being retarded, I am fairly new to programming.

Working on a page in ASP.NET, getting some error that "must be placed within a form tag with runat=server".
I've of course made sure that <form> has runat="server and I even tried adding so that the created textbox has runat="server" too. The basic function of the code is to add a textbox when clicking the button and increasing the number of the id with each textbox. Adding the first box, which is named spec0, works but clicking again produces the error. I am suspecting that the error comes from me fucking up the C# code.

Most of the code you see here comes from searching and adapting the code to the project.

protected int NumberOfControls
        {
            get { return (int)ViewState["NumControls"]; }
            set { ViewState["NumControls"] = value; }
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
                //Initiate the counter of dynamically added controls
                this.NumberOfControls = 0;
            else
                //Controls must be repeatedly be created on postback
                this.createControls();
        }

        private void createControls()
        {
            int count = this.NumberOfControls;

            for (int i = 0; i < count; i++)
            {
                TextBox tx = new TextBox();
                tx.ID = "spec" + i.ToString();
                //Add the Controls to the container of your choice
                Page.Controls.Add(tx);
            }
        }


protected void addnewtext_Click(object sender, EventArgs e)
        {

            TextBox tb = new TextBox();
            tb.ID = "spec" + NumberOfControls.ToString();
            tb.CssClass = "form-control" + " " + "span6";

Lisp syntax is best syntax.

Racket lacks

general-car-cdr

tho. It's very important.

I just realised you can't create a circular list out of a plain list with quasiquotation

`#1=(,@foo . #1#)

just hangs on both SBCL and Emacs Lisp. It's logical tho

>>52884117

>>52884275
Gotta write my own racket/lang that supports this. This means allowing circular data in the code, and making a cycle detecting quasiquote. Wish me luck!

What's the difference between linking and binding?

>>52884974
In what context?

>>52884256
No they're not. You personally having trouble with them doesn't mean there's anything objectively wrong.

>>52885097
I have a compiler, the help menu offers both binding and linking as separate options. I want to understand what that difference is.

Why doesn't this work?

#define delLink(inNode)    inNode->previous->next=inNode->next; \
                        inNode->next->previous=inNode->previous;\

>>52885197
ARE YOU FUCKING RETARDED? TRY THEM OUT FOR YOURSELF AND SEE WHAT THEY DO!

>>52885171
You aren't checking whether inNode->previous or inNode->next are valid, so it will fail for the first or last elements of a list.

>>52885171
try this

#define delLink(inNode)   ( inNode->previous->next=inNode->next; \
                        inNode->next->previous=inNode->previous;\
                        free(inNode);)

>>52884440
>register

>>52885171
See >>52885267

You should also wrap inNode in parentheses in case it is an expression.

#define delLink(inNode) \
do { \
    if ( (inNode)->previous) (inNode)->previous->next = (inNode)->next; \
    if ( (inNode)->next) (inNode)->next->previous = (inNode)->previous; \
    free(inNode); 
} while (0)

>>52885267
I'm using a sentinel. Should have said that. I don't really store anything special for the sentinel so it could be freed but it's not a concern ATM.
>>52885279
That's a syntax error. I can try surrounding my innode's with parenthesis. Probably what you had in mind.

And I think I've figured out an issue if the node I'm trying to delete is expressed as sentinel->next or node->next then it will delete the wrong node. That's probably it.

>>52885323
forgot a ; there

>>52885351
No, but I did forget a \

You don't want the trailing ; because then this would be valid:

void foo(node_t* node)
{
    delLink(node) // note the lack of ;
}

>>52885338
That didn't work. Not sure I did what I had intended. I'm kinda tired.

#define delLink(inNode)    {node* tempnode_=inNode;(inNode)->previous->next=(inNode)->next; \
                        (inNode)->next->previous=(inNode)->previous;\
                        free((tempnode_));} //Braces here so tempnode_ is restricted to the macro scope

You guys do know that the register keyword doesn't really do anything, right? If you have a ton of variables, it MIGHT make a hint to the compiler that you would like that variable to stay in a register over others, but this is not guaranteed. Given that adding is typically always done in a register, your loop counter would have been stored in one anyways.

inline functions are like macro but type safe. there no reason to favor macro over inline functions except when you want a left value. using macros to inline code in C is an obsolete programming technique from the past.

>inline does literally nothing

  unsigned int i;
  for (i = 0; i < size; ++i)
  buf[i] = __builtin_bswap32(buf[i]);

from os.path import expanduser

request = "https://a.4cdn.org" + link[link.find("org")+3:] + ".json"
response = str(urlopen(request).read())
board = request[request.find("org")+3:request.rfind("/")-6]

id_list = [response[e.end()+1:e.end()+14] for e in finditer('"tim"', response)]

ext_list = [(response[s.end()+2:e.start()-2]) for s,e in zip(finditer('"ext"', response), finditer('"w"', response))]

img_list = ["https://i.4cdn.org" + board + ID + EXT for ID, EXT in zip(id_list, ext_list)]


download_dir = expanduser("~") + "\Downloads\\"
new_folder_name = input("Name the new folder: ")
download_folder = download_dir + new_folder_name

print(len(id_list), "files")

for img, ids, ext in zip(img_list, id_list, ext_list):

['えー, え', 'ee interj. eh?, what?; well, yes']

How do I check for the nonpresence of the , without deleting the last character of the first half of the output? My desired output looks like this:

If you knew anything about C, you would know that averaging two ints is implementation defined and thus I'm correct and you can choke on some unspecified behaviour.

I want to be able to iterate through the values in the dictionaries, and maximize points subject to the constraint of a $50000 salary cap. I need to use some sort of linear programming module to do this.

I also want to add a function to scrape relevant historical player data from a site like numberfire so that I can find player variance and covariance and factor that into my lineup generator.

My only stumbling block is that I have no idea what I'm doing.

1) You mean calculate the arithmetic mean between the two values
2) That's only ONE way. In fact any value in the inclusive range [a, b] is a valid median of a and b.

It's exclusive range, not inclusive range.
>a median is the number separating the higher half of a data sample, a population, or a probability distribution, from the lower half
Inclusive range disqualifies this.

If it ways inclusive range is valid anywhere else, it is certainly contradicting itself.

Hey guys, very very new to programming.
Learning python at the moment.
I need to write a script that finds the common
factors of two numbers input by the user. And then it will go on to display all of the common factors.

I'm having a bit of a brain fart about how to go at it, I'm not asking for anybody to do it for me, but I would like some direction. So far this is all I have.

num = eval(input("Enter first number: "))
num2 = eval(input("Enter second number: "))


Not that much lol, I'm just very new to this so I'm coming to you guys, not sure if I need to use a loop. Thanks a bunch.

>>52887624
iterate up to half the largest inputted number, and check if the current iteration goes evenly into both numbers with no remainder. (hint: use modulo).

Can anyone recommend a good intermediate/advanced book, guide or something about modern C++?

I used to program a lot in C++ before C++11, but then I moved to Rust and other languages and lost some skills.
Modern features like smart pointers, auto etc look great and are fairly straightforward, but I would like to learn them in-deep and learn how to use all new features and practices in efficient way.

>>52881397
if we print FizzBuzz (and not Fizzbuzz, note the lowercase b), you don't need to treat the case of both 3 and 5 specially:

#include<stdio.h>

int main(void)
{
    for (int i = 0; i < 100; i++)
    {
    printf("%i: ", i);
    if (i % 3 == 0)
        printf("Fizz");
    if (i % 5 == 0)
        printf("Buzz");
    printf("\n");
    }
}

This actually prints FizzBuzz for i=0 though.

I'm reading over some user's solutions to a problem.
They are traversing through a 2D matrix, but at the end of the array they always set the last value to infinity. The problem is trying to find the minimum distance of values from top to bottom.

def minimumTotal(triangle):
    if not triangle:
        return 0

    cur = triangle[0] + [float("inf")]
    for i in xrange(1, len(triangle)):
        test = []
        test.append(triangle[i][0] + cur[0])
        for j in xrange(1, i + 1):
            test.append(triangle[i][j] + min(cur[j - 1], cur[j]))
        cur = test + [float("inf")]

    return reduce(min, cur)

You can't keep remembering standard library and language's quirks forever, especially when you don't use it and keep switching thought many others.
Of course I'm talking about language-based skills, not general programming skills.

Programming in multiple different languages shows you actually really know how to program. Sure, we all forget differences of syntax sometimes but you should be able to figure out the logic very easily if you can program well

>>52888203
>we all forget differences of syntax sometimes
not true for C++

>>52888096
To make really lot of money out of programming, you need combination of skill, luck, connections and mind of a genius. Eg. Notch had only luck and become rick as fuck.
To get stable, less risky job, you could become java enterprise developer or someone like that with normal skills and knowledge.
Game dev and startups are actually more fun, but usually pay significantly less.
Web dev is easier but has lower pay as well.

Gonna try out non-ide programming just in case it's not just a meme
Which one do I use?

Those and Ruby are about the only popular "modern" languages out there that use dynamic typing
