What are you working on, /g/?
I'm trying to learn how to use OpenGL (the graphics library for C/C++), and am using the following tutorial:
http://www.opengl-tutorial.org/beginners-tutorials/tutorial-1-opening-a-window/
I'm currently on tutorial 2 and am getting the following error/Projects/OpenGLTutorials/ogl-OpenGL-tutorial_0015_33/tutorial02_red_triangle/tutorial02_red_triangle
Impossible to open SimpleVertexShader.vertexshader. Are you in the right directory ? Don't forget to read the FAQ !
Even though I followed the instructions for how to build it on the mac perfectly
What am I doing wrong? And if possible, are there any other tutorials for OpenGL for Mac users?

>>55618256
if you get an exception it skips the rest of the try block

Proof (If you restrict to Int-sized Integer): Printing n fibonaccis takes Ω(n) time, since you have to print n things. fibby takes a constant amount of work before tail recursing, so takes O(n) time. So this is the fastest possible, asymptotically.
If you consider fibonaccis arbitrarily large, I don't really know. This algorithm would take O(n log n) since addition of arbitrary size takes O(log n) time, but maybe it is possible to do better?

I'm stuck with a person who claims to not be all that favorable to OOP and uses the sane parts of C++11/14 but he's gone absolutely mad.

I know he browses this place, he's gone to work now but I don't want to be recognized.
But it's the normal stuff of abstracting and abstracting things that'd take a line or two to write at most.
He doesn't really appreciate the fact that enforcing all these structures upon anyone writing code slows down the process immensely.
>that's not a bad thing anon
Yeah in contrast to doing using namespace std.
But it's terrible. Here I found a place in the code where he introduced a construct for linking sprites to sounds. That doesn't even make any sense here. And all he does is get them as a std::pair and use them separately.
Seems entirely arbitrary and there's no comments to explain the (presumably weak) reasoning for this.
Maybe if I just ask him to comment his code more he will start realizing his issues?
>>55620315
>>55620369
(arg1, arg2) makes more sense if you are feeding it the output of a function that outputs a tuple.
Also I think GHC represents arg1 -> arg2 -> ret more efficiently than (arg1, arg2) -> ret if you don't turn on optimizations. Otherwise they're about equal.
>>55620381
>Maybe if I just ask him to comment his code
He doesn't comments it because he wants to be the only one that understands that mess.

I wanted to make a program to generate one of those colour pickers you get in paint programs.
After some thought it turns out that you can make one by going through every point in a circle and setting it to HSV(angle(center_of_circle, point) / 360, vectorDistance(center, point), 1).
Messing around with the saturation value produces some cool effects.
>>55621186
It's useful for just a pair of cases, like exiting nested loops/switchs, handling exceptions, and other things I can't remember.
Of course, using it in a bad way could lead to spaghetti code, but you need to blame the programmer.

how do I move data (let's say a struct) to a specified memory address?

Why would you wan't to do that? I don't think your OS lets you do it.

Fuck off, skiddie.
A small c program that asks the user to create a string.#include <stdio.h>
int main(void){
char X[];
scanf("%s",X);
printf("%s",X);
return 0;
So basically the user enters a string, and it's size should be however long the user wants it to be.
It doesn't work and I don't know how to go about doing this.
>>55621655
Making your own scripts is being a skiddie now?
>>55621761
Read about memory allocation.
>>55621761
It does not work because what you are doing does not make sense.
>>55621761
variable length arrays were a mistake
>>55621761
}
Also X has no size.
>>55621775
I understand memory allocation.
You have the reference operator & and the dereferencing operator *.
Anyways any more help would be appreciated.
>>55621788
I want it to be whatever size the user chooses. Oh yeah I can do that prompting the user before that.
Thanks. Any more help would be appreciated.
>>55621776
What I am trying to do is ask the user to input a string that will be saved later on into a data type char variable[size].
Here is the updated code.#include <stdio.h> int main(void){
printf("enter the size of the url-string:");
scanf("%d",&size);
char X[size];
printf("enter the url");
scanf("%s",&X);
>>55621878
You didn't declare "size".
X, not &X. X is already a pointer.
>>55621878
you forgot to declare size
you forgot }
You need to indent your code and add a new line before int main
>>55621655
One of those isn't even the original post you baka.
Define skiddie also.
>>55621878
That will not work. You cannot use the stack to allocate char X[size] where size is a variable. you have to use malloc. Also, asking the user how big the string will be is a terrible solution. You should malloc some reasonable size, then read in char by char, reallocing as necessary (increase size exponentially, for example) when your string runs out of room.
meanwhile in sane languages:#include <iostream>
#include <string>
int main() {
std::string s;
std::cin >> s;
std::cout << s << std::endl;
}

thanks it worked!!!
why are arrays always pointers?

what is variable length arrays, introduced in the C99 standard for 420?

This is wrong.

It is the best solution if you are reading from a file for example.
>increase size exponentially, for example
This is a bad idea.

How are you going to train that?

Just a tip: use size_t from stddef.h for sizes and indexes instead of int. (%zu in printf/scanf)

Huh? You can use any editor of your choice.

this is untrue if the IO is buffered
>>55622134
Especially if the IO is buffered. By reading char by char you're just throwing away the work of buffering.
Reading in chunks is better.

What happens if the user lies or is mistaken about the string length? They answer, for example, that the string has 10 characters but it actually has 1000? It seems like you are just inviting the user to overflow buffers here.

do you even know what a runtime is?
haskell can't even run unless it includes those 50k lines
C's runtime is just a few bytes (to allocate the main stack frame and execute main)

You can't anything useful without Libc though.

There is literally nothing wrong with 3d women

haskell needs RTS to run
https://downloads.haskell.org/~ghc/7.10.3/docs/html/users_guide/runtime-control.html

>>55622502
>>55622381
Are you retarded?
If you include std*.h (which I'm pretty sure you will), the program will be linked against a multi-million-SLOC libc.
50k is nothing compared to that.

Do you know how static and dynamic linking works?
libc is usually dynamically linked

Still links to a multi-million-SLOC libc.

You will have to count the standard haskell libs then.

Newfag here, I'm writing a software that need to read files in a certain directory, the problem is that said directory may also be a zip compressed archive.
My solution was to create a "Folder" class; on its initialization it get a listing of the files into the target folder, or, this is a compressed archive, opens it with zlib beforehand. It also set a boolean variable "is_compressed".
Then it is possible to call a function Folder.open(filename) that simply open and read the file if is_compressed is false or, if it's true, extract the file from the archive returning the content.
Does it sound like a decent solution? Also, given that the initialization of Folder class may open (and keep opened) a compressed archive, do I need to close it before the program exits or this is automatically managed by the garbage collector?
>>55622677
>equating including to linking
Yep, you're retarded.
See: >>55622658/usr/lib/libc.so.6is part of your C program's runtime.
>>55622688
libc is not required
RTS is required
you can run a C program without libc
you cannot run a haskell program without RTS
>>55622703
depends on the compiler and the options you give it. I think gcc automatically runs -lc, but that can be turned off
>>55622723
