I'll start it off with a strong 66
Anyone know klingon?

Wow I just generated a random number between 1 - 100 and i got 50, what are the odds?

>>55200255
1 to a 100?

>15. collatz conjecture

#include <stdio.h>
#include <stdlib.h>
unsigned long long step(unsigned long long  n,void f(unsigned long long n)){
    printf("%llu\n",n);
    f(n);    
}
void collatz(unsigned long long n){
    if (n!=1)
        n%2==0?step(n/2,collatz):step(3*n+1,collatz);

}
int main(int argc, char *argv[]){
    printf("%s\n",argv[1]);
    collatz((unsigned long long) atoi(argv[1]));
}

:^)

>>55200673
This doesn't compile.

>>55200673
I made mistake

void step(unsigned long long  n,void f(unsigned long long n)){
    printf("%llu\n",n);
    f(n);    
}
void collatz(unsigned long long n){
    if (n!=1)
        n%2==0?step(n/2,collatz):step(3*n+1,collatz);

}
int main(int argc, char *argv[]){
    printf("%s\n",argv[1]);
    collatz((unsigned long long) atoi(argv[1]));
}

>>55200703
what's the error?

>>55200673
are you calling function in a function you just created?

>>55199345
i suppose

>>55200715
Segmentation fault

>>55200732
not going to happen

wish these challenges were focused around one type of thing
like web devving, or game design, or algorithms
not everybody can do everything

>>55200723
I tried to make the worst working implementation I could :^)

>>55200735
you'd get a segfault if you don't have any args when you run it in the console

./collatz 215434

>>55199345
I got brainfuck interpreter.

I might actually do that.

it's easy as fuck, should take 10 minutes or so

>>55200779
Is it already out of style? :^)

optimizations and doing something neat like targeting llvm would be fun and add more difficulty.

>No anti-aliasing

>>55200849
I have no idea if the simple turtle-style drawing lib I'm using does anti-aliasing and I'm not going to manually implement it because I'm lazy.

Is random.org a uniform random?

can i trust this?

Read the documentation and decide for yourself, fucking sheep.

>>55201048
There is no hard documentation and their code is closed source.

Please shill elsewhere

That's spooky as shit, It's destiny.

fucked the formatting, will try again..

    reverse(sys.argv[1])

Is using a text file for quine considered cheating?

>what is recursion

i wanna ask something
most projects ive seen have a directory structure like src lib test stuff like that
when i write something its just a single c file
how do into better structure code and divide it into parts. is there docs or guidelines
and i wanna ask how to generate and do testing
