>>56976481
Help, I recently graduated from a theoretical CS school and can't answer this programming interview question: "write a method that converts a floating type number to a rounded string with 2 decimal digits".

Here's my attempt that isn't working right.

    public string ShortenFloatString(float valueToShorten)
    {
        string xString;
        string xString2 = "";

        xString = valueToShorten.ToString();

        if (xString.IndexOf('.') > -1)
            xString2 = xString.Substring(xString.IndexOf('.'));

        if (xString2.Length > 3)
            xString2 = xString2.Substring(0, 3);

        if (xString.IndexOf('.') > -1)
            xString = xString.Substring(0, xString.IndexOf('.'));

        if(xString2.Length > 2)
        {
            if(xString2[2] == '9')
            {
                int num = int.Parse(xString2[1].ToString());
                if (num <= 9)
                {
                    num++;
                    xString2 = "." + num.ToString();
                }
                else
                {
                    num = 0;
                    xString2 = "." + num.ToString();

                    int firstNum = int.Parse(xString);
                    firstNum++;
                    xString = firstNum.ToString();
                }
            }
        }
        return (xString + xString2);
    }

I have to email back the correct response soon.

As I said already, I'm pretty sure they want an implementation for ftoa, and not a one-liner that relies on String.format.

>>56976563
How rude.

in Python this is just

Casting a float to an int doesn't round it, it floors it you retards.

>>56976643
the numbers after the . go away right

>first time actually using a bash script to actually do something

Wew, feels great, worked on my first try too which is awesome. Just taking a folder of pictures and making blurred versions of each picture in another folder. Going to have my startpage background cycle with my desktop wallpaper, except blurred.

>>56976634

Look it up.

>>56976634
float to array doo

>>56976643
Flooring is a form of rounding

How do I take a string var in node.js and pipe it into a subprocess?

>>56976643
>>56976666
Plus you can just add 0.5 and then multiply it by 100

>>56976681
Print to string, check third digit after decimal to determine if you have to add 1 to second one, then simply trim that string.

>>56976634
doesn't have a decimal point

>>56976691
What are you on about? Add 0.5 and floor and you've got rounding to the nearest integer. You can also take away 0.5 and ceiling

>>56976691
>>56976697
For instance

1.00 -> 1.50 -> 1
1.25 -> 1.75 -> 1
1.50 -> 2.00 -> 2
1.75 -> 2.25 -> 2
2.00 -> 2.50 -> 2
2.25 -> 2.75 -> 2
2.50 -> 3.00 -> 3

>>56976694
just add a . in the space

I need a fucking OpenSSL mage.
What's the difference between

SSL_get_verify_result()

and

X509_verify_cert()

?
Docs say the former "returns the result of the verification of the X509 certificate presented by the peer, if any."
And the latter "attempts to discover and validate a certificate chain based on parameters in ctx."

Are there two different kinds of verification?
Does the first function just get check if the second one succeeded?
I can't organize this API in my brain, it's just a collection of functions that seem superfluous or even contradictory in purpose, and many are deprecated or are lower-level alternatives to other functions.
What does the process of certificate verification look like using OpenSSL and C?
What is my flow?

I have this:
https://ghostbin.com/paste/vpukk
As you can see I have no idea what I'm doing.

>>56977073
>2 decimal digits

if (num[1].length > 2){
        num[1] = num[1].charAt(0) + 
        (Math.round(Number(num[1].slice(1,3)) / 10));
    }

Replace the if statement with this.

>>56977089
Oh, I assume you just used this.

I'm pissed I didn't come up with that to begin with, That looks nice doesn't it

>>56977138
Speaking of OpenSSL how the fuck do I install it on windows.

>>56976525
Could anyone tell me what's the benefit of knowing something like this? I am not really into CS/CE. I just like to try "programming" for ""fun"". I understand already they try to weed out the bad ones from the good ones, but I meant the actual question or "problem". Aren't most of them already done and provided freely online from other people?

>>56977186
>Aren't most of them already done and provided freely online from other people?

Stop thinking like this, right now.
You're never going to get anywhere if you just copy paste solutions from pajeets on stack overflow.

>>56977198
Thinking? I am just merely asking out of curiosity.
Would be great if you could explain the idea with putting out this kind of challenge(the one the poster mentioned about).

>>56977138
i *think* the first one uses an ssl pointer and verifies the certificate used to open the connection. The second one is used to verify a certificate chain from the provided context

But i'm just guessing from examples here: https://www.ibm.com/developerworks/library/l-openssl/ and the docs. I've never actually used this myself and I've not done C in ~12 years sooo large grain of salt there.

>>56977186
I'm the guy that gave the answer:
>>56977089

I don't know the benefit. I've been learning to code for a few months and I've realized I like making algos a lot better than making things.

From what I've heard from web developers, it doesn't have anything to do with the job. It may come up here and there and that's about it.

With other forms of programming, I'm hoping it's different. Mind you this is something people can do in a matter of minutes.
I'm curious what kind of work revolves around this kind of thing, where algorithms are more created in months etc.

But yeah, I think for 99% of programming you'll never need it.

>>56977186
The point is for you to prove you have problem solving skills. Surely you know basic string manipulation and numeric calculation syntax in at least one programming language (these questions are give to CS grads remember), but can you combine the knowledge of those things into a solution to a specific problem? Or can you only follow directions and copy-paste from stack overflow? Most employers need independent problem solvers, otherwise you are just going to be pestering your co-workers for anything non-trivial and end up being a net cost on the team.

>>56977267
These questions are given to everyone.

>>56977262
>>56977267
Thanks, these are the kind of answers I like to read and get an understanding from.

>>56977212

These aren't about solving a problem that hasn't been solved. Usually they are about seeing a candidate do this in real time (I don't get "mail in" coding interviews) and then throwing a few curve balls at them to see if they can adapt it. even if they memorized the solution to the base problem they need some aptitude to be able to adapt. As they do well you push them more and more to see how much is actual knowledge and experience and how much is reading interview books and copy-pasta from SO.

Anyone worth their salt going for a development job should understand the basics well enough to solve simple toy problems in a reasonable amount of time in the language they know best.

If you don't care about the jobs, then solving these might not be fun for you. Many people use them as tests of skill or challenges to see how well they can solve the problem. e.g. can I do it in less lines of code, can i make i run faster, etc. Others use them to practice knowing there are solutions they can draw from to learn where they get stuck or to validate their thinking.

*shrug* lots of reasons to know how to do this, but it's certainly not a requirement for anyone who just does this for fun and doesn't really care how things work. If you do start diving in to how the languages work then these tend to become fairly easy to pick up and solve.

>>56977298
Yeah, I have bootcamps in mind. Hack Reactor actually recommends you learn Js with codewars challenges, reading as little as possible

>>56977426
Js syntax***

Is this possible in any language?

unction add(n) {...}

 

add(1); //=> 1

add(1)(1); //=>2

add(1)(2)(1); //=>4

The only way I can think of to do it is to add a constructor to numbers, or to return some kind of thing that's a number in every context except for when it's invoked like a function.

>>56977467
This is possible in Haskell:

add 1
add 1 1
add 1 2 1 
-- same as (((add 1) 2) 3)
-- or in another language add(1)(2)(3)

>>56977487
*1 2 1

>>56977487

What is the type signature of the function add here? Because it would seem as though in Anon's example, it returns both an integer and a function, and not a product type of the two...

>>56977467
That would require some weird type where it's a value, but you could call it as a function.
If I'm not mistaken, C++ is that retarded.

>>56977467
This is FP 101, lisp-based languages will let you do things like
(+ 1)
(+ 1 1)
(+ 1 2 1)

Most imperative languages will let you do equivalent things by passing in arrays or an arbitrary number of parameters.

>>56977512
>it returns both an integer and a function
Exactly, that's how it works in Haskell
You use some type class magic and then the typechecker can figure out which you need

Basically it ends up having a type
a -> r

and r is either the sum or another a -> r

>>56977524

So it's a sum type? Like a union?

Although if you think about it, it would have to be a product type. Because it has to store both the integer returned and the function, depending on how the result will be used later...

>>56977556
No, it's a polymorphic type that is either
r
or
a -> r

>>56977487
Hey, what you implemented is not the same as what was pictured.

What you implemented in haskell is a variadic function which can handle multiple args.

That's possible in almost every language.

What's pictured here is:

add(1); //=> 1

add(1)(1); //=>2

add(1)(2)(1); //=>4

Return type of add(1) looks like a number, and yet that number has an overridden () function.

>>56977563
That was one of the answers I was thinking could make this possible; a kind of data type that would act like a number in all situations except for when it's invoked with parenthesis.

>>56977138
SSL_get_verify_result probably ends up calling X509_verify_cert; it's specifically a specialization for "I have this ssl connection, check to see if X509 certificate the server presented verifies against my collection of CA certs."

You'd use X509_verify_cert in a situation where you may not necessarily have an ssl connection set up and just want to verify that a cert can be validated against a set of CA certs. This is pretty reasonable since there's no reason you can't use an X509 cert to check the signature of an arbitrary piece of data not associated with an ssl connection.

>>56977467
C++

 
int function(vector<int> vector); 

function(vector<int>(1,2,1));

Can also use ellipses.

>>56977556
>>56977563
Oh, when I say "either" I don't mean like a sum type, I mean that it's kind of like a template or a generic with a restriction kind of like type traits or interfaces


>>56977570
It is what you wanted though.
Haskell functions only accept 1 argument.
It quite literally gives you back something that is either a number (result) or a function

>>56977588

x=add(1); // =>1
y=x(1); // =>2
z=y(2); // =>4

This is what I believe he wanted and your haskell add function does not allow that.

>>56977601
It does allow that

>>56977514
Yeah I was thinking C++ could let me overload operator().

Was actually going to hop into C++ and start fucking around with that.

Only problem I can't think of, on how to solve, is to make the 'class' or whatever behave like a number in all other situations

>>56977516
I know a little but of lisp and + 1, + 1 1, + 1 1 is same as add(1), add(1, 1), add(1, 1, 1) - variadic arguments.
Not same as add(1)(1)(1), where the returned data type acts a number in all situations save for invoking ()

>>56977607
Show us the implementation.

>>56977615
Working on it

>>56977563

If it only could return r or a -> r, then one could not do add 1 2 1. The add 1 call would return an a -> r, not an a -> a -> r. What is described could be used at least once more, and presumably, used indefinitely.

>>56977628
No, because r (the return type) could be another function

>>56977609
You can overload the cast operator so that your object gets implicitly converted to an int when an int is required.

>>56977632
Rather than converting something to an int, what would make this doable would be to convert it to a function when required

32KB, 821x482px

ok, but you get problems if you use stuff like x/y/z multiple times as arguments (in z I use x once)

>>56977678
and the type is
forall r. SumT r => r

so basically, any r that has an instance for SumT - which includes
Integer
Integral -> Any SumT (and SumT could be another Integral -> ...)

>>56977630

Oh. Derp. I thought r was representing the integer return value.

>>56977704
The point is that r _could_ be an integer return value, or it could be another function - which in turn count return an integer, or another function, etc etc

>>56977711
and when I say could
it's entirely up to the person calling it
it is both until specified otherwise

>>56977678
Whoops, never mind about the problems, I was just an idiot and the code I first tested had z include itself.

If it could short-circuit that might be interesting though.

>>56977857
everything is an object in python, even procedures and integers.

object(...)

is syntax sugar for

object.__call__(...)

thus every object that has the __call__ method is callable.

for example

def foo(n)
 return n + n

foo(1)

is actually

foo = function("return n + n")

foo.__call__(1)

I took a go at this using C++ (by the way, I'm not a sepplesfag) and I don't think I've ever been more disgusted at myself.

    operator T() const {

}

{

}

>>56977904

add(1)

does the '1' go into the 'self' parameter, or the 'n' parameter?

>>56977924
I can tell what everything does except for

operator T() const {
        return val;
    }

What's operator T() const?

I think T is the template type right? So is that similar to saying some like 'int()' ?

Is that a/the type-casting operator?

>>56977957
const on member functions means "this functions does not modify the state of the object"

>>56977967

that aside what does 'operator T()' mean?
what is 'T()' ?

If the template type is in.. like shit<int>

Is that like saying 'operator int()' ?

Ok so inherit, if it's int, is actually a special key word...

I tried
>>> int(3)
and got 3

so int is a kind of class in Python that can take a number and return it.

so

class add(int):

does this mean that because add inherits from int, it can do the same thing as:

int(2) // 2

>tfw [code ] is nestable.

oh, sorry.

the self/this argument is explicit in python but a method object which bind an instance to a class procedure is made to avoid passing the said argument every time you call a method.

for example,

class Foo:
  def bar (self):
    print(self)

ins = Foo()

here, ins.bar is not the same as Foo.bar but a method object created during the instantiation that bind Foo.bar to ins

something like

procedure insBar():
  return Foo.bar(ins)

ins.bar = insBar

If you want to feel unlimited power, try abusing method_missing and instance_eval in Ruby... along with the ability to arbitrarily add and remove methods from the base classes.

is this possible in multiple versions of lisp?

>>56978050
wait so you're saying that in the class (Foo) definition we have to put self as an explicit parameter.

but when we instantiate Foo, we can call Foo's methods and self will be implicitly passed as a 'hidden' 1st argument, which will land in our 'self' which we explicitly defined when we defined Foo?

>>56978105
>but when we instantiate Foo, we can call Foo's methods and self will be implicitly passed as a 'hidden' 1st argument, which will land in our 'self' which we explicitly defined when we defined Foo?

Meant:
but when we instantiate Foo, we can call (THE INSTANCE VARIABLE)'s methods and self will be implicitly passed as a 'hidden' 1st argument, which will land in our 'self' which we explicitly defined when we defined Foo?

>>56978080
it's scheme, not list
but as far as I know, syntax-rules and ellipsis are part of the standard and should be supported by every implementation

>>56978116
They're standard but they're not supported by all implementations. I believe most of the major ones do though.

This is how we break the rules in Ruby:

class Integer
  alias :call :+
end

def add n
  n
end

add(5) # => 5
add(5).(7) # => 12
add(5).(7).(2) # => 14
add(5)(7) # => syntax error, but it would be like this with any callable object.

>>56978042
int(1) is actually nothing more than calling the constructor of the class int. everything is an object, even types which are instance of the the class `type`.

therefore,

yes, that makes high order programming much easier since a method is bound to its specific instance.

if foo.bar(...) were just syntax sugar for Foo.bar(foo, ...), then you couldn't pass foo.bar without also passing the instance.

for example with this system, you can do

I'm trying to print out a 2 dimensional array of my datatype but I get this compiler error.
Error subscripted value is neither array nor pointer nor vector.

void printField(cell field)
{
    for(int i = 0;i<rows;i++)
    {
        printf("%c", field[i][i].current);

Here is my datatype declaration.
typedef struct{

  char next;
} cell;

So, do you guys contribute to any FOSS projects?

Can anybody explain pointers to me? I don't get them, at all. I mean, I get the whole "when you order from Amazon you don't uproot your home and go to them to pickup your delivery, you send them your post code and have it delivered to you" part, but I can't get my head around translating it to programming since it's all hapenning within the same processor.

And also, what's up with pointers to pointers?

I'm starting to wonder whether it would be better to pickup asm basics to see if they give me any insight into those fucking pointers. They are supposed to be a very basic concept and I'm stuck on these fucks for like 2 years now.

field doesn't appear to be an array, pointer, or vector. It's just a single value. You can't index into a single value.

>>56978336
Also, do you mean to print the full array, or just the main diagonal? Because your code is set up to print the main diagonal (every time you index into field, you're using the same x and y).

Things are stored in memory. The computer knows where things are stored in memory by their address. Pointers hold the address.

int thisIsAnInt; 

thisIsAnInt= 5; //we have assigned the integer value 5 to the memory where thisIsAnInt is stored 

int *thisIsAPointerToAnInt; 

thisIsAPointerToAnInt= &thisIsAnInt; //the & gives us the memory address of a variable. we have assigned the address of thisIsAnInt to the memory where thisIsAPointerToAnInt is stored. Note that thisIsAPointerToAnInt is not a memory address, it is a variable that holds a memory address, as such it needs it's own memory address to store that address.

int **thisIsAPointerToAPointerToAnInt; 

thisIsAPointerToAPointerToAnInt= &thisIsAPointerToAnInt; //we have assigned the address of thisIsAPointerToAnInt to the memory where thisIsAPointerToAPointerToAnInt is stored. As pointers are not memory addresses, but merely variables that hold memory address and need their own memory addresses, this pointer to pointer will not hold the same address as the pointer it points to, it will hold the address of the pointer itself. 

int thisIsAnotherInt= thisIsAPointerToAnInt; //this won't work because we are trying to assign the memory address the pointer points to a non-pointer. Instead we must dereference. 

thisIsAnotherInt= *thisIsAPointerToAnInt; //this will work. The dereference operator looks into the memory address held by the pointer to retrieve the value. 

thisIsAnotherInt= *thisIsAPointerToAPointerToAnInt; //this won't work. Although we've dereferenced our pointer, the value it points to is another memory address so we must double dereference. 

thisIsAnotherInt= **thisIsAPointerToAPointerToAnInt; 

int *thisIsAnotherPointerToAnInt= *thisIsAPointerToAPointerToAnInt; //here we've dereferenced the 'pointer to a pointer to an int' to retrieve the 'pointer to int' and assigned the memory address it holds(as opposed to it's own memory address) to another pointer to int. 

>>56978361
well you know how an array works right?

just envision all of your memory written to a single linear array

a pointer is just a number of the index where that data begins

so if you have some data

F A G G O T

stored at indices

1488 1489 1500 1501 1502 1503

in the midst of all the other memory, a pointer would just be the number 1488, where the data begins, rather than the literal values

F A G G O T

in C, referencing an array index with

array[n]

is just syntactic sugar for the pointer (memory address number) where the array begins + n

Bored.

so, in my program I am memory mapping a file. I have a char pointer to said memory mapped file. I also have a function to read a line from the char pointer.

char* readline(char* file, int line)
{
  int l = 0;
  char* temp = (char*)malloc(2048);
  for(int i = 0;;i++)
  {
    temp[i] = file[i];
    if(file[i] == '\n')
    {
      l++;
    }
    if(l == line || i == 2048)
    {
      return temp;
    }
  }
  
}

it basically reads until it finds the newline character and it also stops when an overflow is about to happen.
did i do good or do i deserve compsci_grad.png?

I've been thinking about memmove in the presence of memory mapped in multiple places.

Let's say you have char *a, *b; which point to different addresses such that the pages [a, a + 4096) and [b, b + 4096) don't overlap. Now let's assume that those two pages refer to the same memory.

The common memmove implementation will now check if a < b or a > b and then copy byte by byte in the right direction. Naturally this is wrong because the pages overlap.

What part of the C standard forbids using memmove with such overlapping pages?

>>56979625

>>56979670

i should just include the || i == 2048 in the for loop

Fairly easily, if you already know vector/matrix mathematics. If not, it's going to be harder.

You also need some way to create data for your environment. You could try loading Quake maps, the BSP format is very well documented. And then you can use already existing Quake mapping tools to make levels. You just read the BSP structure and use the PVS to determine what's visible. Easy money. In the late 90's and early 2000's, making a Quake 1/2 level viewer was practically a rite of passage for aspiring 3D programmers.

Rendering is the hardest part. The easiest way is to just use OpenGL. It takes a few hundred lines to set up modern a OpenGL environment with shaders and buffers (add a few hundred more if you're under Windows and need to load OpenGL extensions because Windows isn't going to do that for you). Then you just determine what's visible based on camera position and view direction, update the buffers and issue a few drawcalls and that's it.

If you don't want OpenGL, you better already know how to project, clip and render texture mapped 3D polygons in software. You know assembly, right? Without assembly it's going to be too slow if you need more than a few hundred polygons.

For creating a window and reading keyboard/mouse, you have glfw and SDL2. Both are C libraries and will only take a 20-30 lines to set up. Enjoy!

>>56979556
Languages like C and C++ use typedefs like size_t to get around these sorts of silly issues.
I don't know why Java didn't do something similar, or just use a largest possible integer type.

class intSet(object):
    def __init__(self):
        self.vals = []
    def insert(self, e):
        if not e in self.vals:
            self.vals.append(e)
        def member(self, e):
            return e in self.vals
        def remove(self, e):
            try:
                self.vals.remove(e)
            except:
                raise ValueError(str(e) + ' not found')
        def __str__(self):
            self.vals.sort()
            result = ''
            for e in self.vals:
                result = result + str(e) + ','
            return '{' + result[:-1] + '}'

>>56979709
Thank you for the comprehensive answer, but I am not looking to make my own 3D engine, that would be too much for me. What I want is a simple 3D library where I wouldn't have to touch OpenGL. Something like Irrlicht, but for C.

>>56976525
so did you get the job?

>>56979684
Memory mapping isn't a concept in the C standard, so it doesn't have any requirements about it.
Even then, memmove works fine if the address space overlap. It moves them "as if" copied to a temporary buffer first. You're probably thinking of memcpy.
With memcpy, it seems like it would just be undefined behaviour. You're copying between objects that overlap. I don't think there is a requirement that the objects have to be at the same place in memory to be overlapping.

>>56979862
>You're probably thinking of memcpy.
No, I'm thinking of memmove. The typical memmove implementation looks like this:

if (dst < src) copy_downwards; else copy_upwards;

>>56979781
Unfortunately most 3D engines and environments tend to be written in C++.

But take a look at Corange (https://github.com/orangeduck/Corange). Maybe it suits your needs.

Wikipedia has a list of game engines (https://en.wikipedia.org/wiki/List_of_game_engines), sort it by language and see if something interesting pops up.

>>56979894
I don't know then. This seems like an incredibly obscure and esoteric situation that you should probably bring up on some POSIX/glibc/GCC/whatever mailing list, not 4chan.

>>56979781
https://github.com/septag/darkhammer

I think that at least one of the python bindings for irrilicht had c wrapper which you could use.

Writing C wrapper for c++ game engines is one approach.
You could try with engine in some other language that talks easily to C like pascal, haskel, ocaml but it would likely require you to write some kind of wrapping code.

Not the guy that replied you but for character movement you need a physics simulator to detect collision. Using plain OpenGL is retarded unless you want to learn about 3D concepts, you should go with Ogre3D/Irrlitch.

I made this with C++ and Ogre3D and bullet, that is as close as you can get without using direct OpenGL or a defecation like Unity.

There aren't any pure C engines that are mature enough for proper usage.

Yes, i maintain a todo of what should be done next but nobody should start to undertake a large project. You start with a small trivial project, and you should never expect it to get large. If you do, you'll just overdesign and generally think it is more important than it likely is at that stage. Or worse, you might be scared away by the sheer size of the work you envision. So start small, and think about the details. Don't think about some big picture and fancy design. If it doesn't solve some fairly immediate need, it's almost certainly over-designed. And don't expect people to jump in and help you. That's not how these things work. You need to get something half-way useful first, and then others will say "hey, that almost works for me", and they'll get involved in the project.

About 28%-40% depending upon the state and your deductions.

Does anyone here experienced with cmake?

I cannot seem get cmake to link the library without being too specific.

I have a library I have installed myself, so I am sure that everything about that is the problem.

It is located in /usr/local/lib, but I want cmake to be able to find it automatically.

eg. my libary is /usr/local/lib/libapp_x86.a

This works

find_library(
    APP_LIBRARY CONFIG REQUIRED
    NAMES app_x64
    PATH_SUFFIXES lib
    NO_DEFAULT_PATH
    PATHS /usr/local/lib
)

How do I make it find it where I am less specific?

>>56980990
The CPU cache is a special piece of high speed ram that is part of the CPU. When the CPU needs to access a piece of memory, it will copy it to the CPU cache first, then do a few operations, then copy it back to the main ram when done.

#define add(n) n + add
#define add 0

nothin personnel niggos :^)

>>56981023
what does that have to do with volatile?

>>56981051
like the book says, volatile means anything written to the cache must immediately be copied back to main ram. It prevents issues when writing to memory from multiple threads.

i'm following this tutorial
http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/
but it's written for WAMP and not LAMP. i created a folder android_connect in var/www and created the php test file, but when i go to http://localhost/android_connect/test.php it says not found on this server. what am i doing wrong?

i asked in /wdg/ and it's dead

>>56981085
I don't think you know how the cache actually works and neither does the author of this book. No wonder my quips don't have the desired effects.

>>56981046
add(5)(4) * 3

>>56980990
>not cached in CPU cache
How the fuck are they going to make that work?
Sounds slow as fuck if they can. Storing in CPU cache shouldn't even matter in architectures where caches are write-back and there is cross-core cache access lines for shared data (like x86).

>>56981046
is this c ?

#include <stdio.h>

#define add(n) n + add
#define add 0
 
int main(void)
{
    int n = add(5)(6)(7);
    printf("%d\n", n);
}

prog.c:4:0: warning: "add" redefined
 #define add 0
 ^
prog.c:3:0: note: this is the location of the previous definition
 #define add(n) n + add

Why do you think that?

>>56981005
thanks for the first serious answer

>>56981210
Because the cache is coherent. There is no point writing anything back to main memory because only one cpu at the time can have write access to a location in the cache.

I prefer shapes that tile and triangles are the simplest. Squares are not as interesting and hexagons are slightly more difficult, but they're doable in like five minutes.

Then there are more complicated things like the Penrose tiling (pic related), which would be extremely cool, but I'm not sure how to generate it such that it's both efficient and easily maintainable and modifiable.

>>56981336
ooh that looks really good. Do you just start from the center for the triangles or do you just go from the top left to the right then down

>>56981336
The more interesting question is how many different colors do you need to color it so that no two adjacent fields have the same color.

>>56980811
thanks for saving me the time. how much would you accept to do my daily shitposting for me? I can set up a contract and transfer my trip code

>>56981232
huh? But that's the whole reason volatile needs to flush the cache on every write. So that other CPU's can immediately see the change in main memory. Unless I'm missing something.

no, there are shapes that touch four different other shapes, no way 4 colors fit there

You're right. It depends on how you define adjacency.

>It depends on how you define adjacency.
y

>>56981488
The usual definition, roughly speaking, is that two faces (shapes) are adjacent if they touch with at least one edge, not vertex.

class Test {
    static int i;

    static {
        System.out.println("In Test: " + Main.i);
        i = 1;
    }
}

class Main {
    static int i;

    static {
        System.out.println("In Main: " + Test.i);
        i = 1;
    }

    public static void main(String[] args) { }
}

Fucking java I can't even right now.

>>56981501

Does NUMA not allow cache access across nodes?

Is there any c++ specialist here?
I am trying to check for the null character in an array of strings. But it always gives me seg error.

//something like this
string a[3]; int b=0;
a[0]="Just"; a[1]="fuck my"; a[2]="shit up";

while(a[0][b]!=NULL){
cout<<a[0][b]<<endl;
}

I use the getline function for the string initialization btw. I need to check this array shit char by char and it always gives me seg error when i try to compare chars with null for some fucking reason.

Have an API endpoint that returns on object like shown in the Stuff Class. How do I iterate through this object to get the values returned? Can't modify the real endpoint.

    public class Stuff

        public string Bullshit;

        public object ReturnObject()
        {

            DataTable dt = new DataTable();
            dt.Clear();
            dt.Columns.Add("Id");
            dt.Columns.Add("Bullshit");
            object[] o = { "1", "Status1" };
            dt.Rows.Add(o);

            var retObj = from a in dt.AsEnumerable()
                         select new
                         {
                             Id = a.Field<string>("Id"),

There's a waterfall of problems here.
NULL is depreciated, and should be replaced with nullptr.
But that's not what you want here anyway. You're looking for the null terminator which is '\0'.
But std::string doesn't use null terminators.

You can use a simple for each loop instead.

 
std::string a[3];
for(std::string &str : a) 
{
     for(char &ch : str) 
     {
            std::cout<<ch<<std::endl;
     }
}
