How do I return an array? I have this matrix multiplier:

template <typename T, size_t U1, size_t V1, size_t U2, size_t V2>
void mult (T (&A)[U1][V1], T (&B)[U2][V2])
{
    if (V1 != U2) return void();
    
    T output[U1][V2];
    
    for (auto &i : output)
    for (auto &j : i)
    j = 0;
    
    for (unsigned C1 = 0; C1 < U1; C1++)
    for (unsigned C2 = 0; C2 < V2; C2++)
    {
        for (unsigned C3 = 0; C3 < V1; C3++)
        output[C1][C2] += A[C1][C3]*B[C3][C2];
    }
    
    disp(output);
}

And it works fine, but all I can do is write out the array on screen. The answer is destroyed once the function ends, so I can't just pass a pointer back. What do?

(I would ask /sqt/, but nobody there can code)

>>54996861
The way I read it is: Sometimes you want the result of something to depend upon the execution of gloop. Other times you don't want the result to be determined by the execution of gloop, so you jump to either arfle or barfle. It just looks clever to me.

>>54996861
I've once used this in a serialization procedure which takes an object and turns it into json.
It was structured like this:

string serialize(obj) {
    for p in obj.properties:
        serialized.append(typeHandler(p))
    }
}

the typeHandler prodecure would check the type of a property and execute a serialization procedure based on it - if it's an object call serialize(), if it's a numeric value, serialize it etc.

typeHandler(prop) {
    if prop.isObject() {
        return serialize(prop.asObject());
    } else if prop.isNumeric() {
        return '"' + prop.toString() + '"';
    } else if prop.isArray() {
        for p in prop.asArray() {
            serialized.append(typeHandler(p))
        }
        return serialized;
    }
}

However if typeHandler encourntered an array, I could assume the type of every element within that array has the same type, therefore I only needed to determine the type once, and can then jump to the type I already determined:

typeHandler(prop, &type) {
    switch(type) {
    case -1: //type unknown, check types
        if prop.isObject() {
            type = 0
    case 0:
            return serialize(prop.asObject());
        } else if prop.isNumeric() {
            type = 1
    case 1:
            return '"' + prop.toString() + '"';
        } else if prop.isArray() {
            type = 2
    case 2:
            arrType = -1
            for p in prop.asArray() {
                serialized.append(typeHandler(p, &arrType))
            }
            return serialized;
        }
    }
}

That way I only have to check the type once, and can then use a jump table for successive calls.

But this is not necessarily true by any means, certainly not according to the JSON standard.
Do you really think it's worth the negligible performance increase to omit a type check or two and also make your code incorrect?

The goal of writing software is not to befuddle anyone maintaining it (it could be you) it's to write a working product.

The problem is, once the product is released, management will shift the goalposts to something else, so your code ALSO has to extend to new scenarios. That code doesn't look like it extends easily.

A much easier way to write that EXACT logic, is to switch on mode, and have each case be a separate method/function. Using the stack is a bit less memory efficient, but will boil down to the same instructions to the processor, will do the same task, and will make people not hate you.

Doesn't this just

if((mode==0||mode==1) && gloop(a,b)){ 
 result=arfle(a,b);
}
else{ //covers the case 2:
 result = barfle(a,b);
}
return(result);

There's no default case so the only valid values are [0,2].

Is maybe the point of writing it like that that you can easily split the different cases but you wanted to use the case 0 to use gloop(a,b) to check which case you go into?

So it should be more like

switch(mode){
 case 0: if(gloop(a,b)){
 case 1:
    result=arfle(a,b);
    break;
 }
 else{
   case 2: //maybe we want multiple of them here aswell. I'd put the case before the result= if that's not the intent
    result=barfle(a,b);
    break;
 }
}
return (result);

Racket lisp has super-c, which lets you write inline C code. They also have modules for Algol 60 or 68 ECMA+JavaScript so you could inline those as well. The ECMAscript language is provided as a separate language on top of racket, so you'd have to wrap it in an explicit module expression if you wanted it inside of another file. You can evaluate JavaScript expressions using the other library with just the eval-script function it provides though.

Something like that. You first assume the maximum is the first number, then you go check for every other number whether it's bigger, if it is, then that's the new maximum etc.

Why did you pose that as a question?

Got a Samsung Gear S2 Smartwatch as a present. Now, I'm trying to write an app which show's me the nearest bus/train/tram-stations with departure times of the next few busses/trains/trams.

It's a Tizen system and the Online-API only returns JSON stuff. Using xmlhttprequests seems to only work only for XML stuff. A async call doesn't seem to work yet.

>>54999639
>Is there any way to do it using a do while?
Of course there is. All a for loop is

for(a; b; c)

. a is initializing a variable before the loop takes place, b is the test to see if the loop should take place, and c is the action taken at the end of every loop. You can easy rewrite it as

a
while(b) {
    ...
    c
}

That's not bad. False the value of not the same as the word false in a string. Why would they be equal? False isn't "nothing", so its not equal to null. Null is undefined. Strings, like in C and other languages, are indexes, so the empty array just returns zero. That example is even given twice. It's a little quirky to have something that's empty return zero, but I get it. It's not any worse or weirder than lisp's "if it ain't nil, it's #true" and boolean short circuiting.

To be honest, that truth table looks very reasonable to me and I don't even use JavaScript. Some of you guys go out of your way to get mad about dumb shit.

So I'm trying to do some shit in C++, and I'm trying to return an array from a function. I googled it and people talked about pointers and whatever.

What are pointers and how do I use them?

>>55000726
A pointer is like a dick. it points

>>55000726
I'd give you a few pointers but they might send you into disarray.

whoops forgot my code tags

here's a problem
you can interpret a structure like this:

<large header>
<small header>
<text>
<text>
<text>
<small header>
<small header>
<text>
<large header>
<small header>
<text>
<small header>
<large header>
<small header>
<text>

which should obviously be sorted like this:

<large header>
    <small header>
        <text>
        <text>
        <text>
    <small header>
    <small header>
        <text>
<large header>
    <small header>
        <text>
    <small header>
<large header>
    <small header>
        <text>

in an XML file
how would you go about setting up a loop for nesting that? I'm completely lost

I mean one possible solution is a 2d array where you assign a label to each header or text and then interpret it later but that seems like there MUST be a better way to do it

A pointer is the location in memory of whatever it's pointing at. You usually shouldn't return a pointer from a function because the thing being pointed at will automatically be cleared from memory.

So I just learned that my game engine supports custom DLL's for importing into games when they are compiled. This is fantastic because there is a use I really need form one that is very simple but the game engine I am using isn't capable of doing it. I need to get the window color, the thing you can change in the personalize settings on Windows. I have already gotten some help and source code and was able to make one that gets the ACTIVECAPTION color which prior to windows 7 I believe worked. However I need this feature for 8 and 10 in mind and on these platforms it only returns a light blue color.
I know VERY little about C++ so I was helping someone could lend me a hand. Here is my source for the DLL:

#include <windows.h>
#define DLLEXPORT extern "C" __declspec(dllexport)

COLORREF GetBrushColor(HBRUSH hBrush) {
    COLORREF color = 0;
    LOGBRUSH logBrush;
    if (GetObject(hBrush, sizeof(LOGBRUSH), &logBrush)) {
        color = logBrush.lbColor;
    }
    return color;
};

DLLEXPORT double GetCol(void) {
    return GetBrushColor(GetSysColorBrush(COLOR_ACTIVECAPTION));
};

Ive read about using DwmGetColorizationColor to get it but I dont know how this works.
Any help would be appreciated :)

Let me rephrase my question into something more specific.

I currently know Java, C# and C, I have developed a few projects and would like to build a website to show off my portfolio.

Should I build a website using Python or Javascript?

Is there a way to rewrite this so that I don't get an uninitialized variable warning on compile?

template <typename T>
    T SelectQuery(std::string QueryText)
    {
        T ReturnType;

        try
        {
            // Get the value
            otl_stream i(50000, // buffer size
                QueryText.c_str(),
                database
            );

            while (!i.eof())
            {
                i >> ReturnType;
            }
        }
        catch (otl_exception& p)
        {

>>55000726
A pointer represents an address in memory of the thing you want. When you leave the function, the array goes out of scope and you don't have any way to refer to it anymore. So what you need to do is tell the system to allocate memory for the array somewhere permanent, and then all you need to do is keep track of the address (i.e. the pointer). You can use malloc(), which allocates the amount of memory you ask for somewhere and returns you a pointer to it. Just remember to free the memory when you're done using it.

woah dude, your understanding of the transitive property is totally fucking broken. like to the point that i don't think you understand it at all.

just because the crossdressing community is predominantly constituted of white guys in their 20s doesn't mean that it's "very popular" in any other community of white guys in their 20s.

to make this especially concrete since abstract reasoning tends to confuse retarded people...

if there are 10 people in the world who crossdress and they're all 23 year old white men, and 1 million people in the world who program (and they're all white men in their 20s), then your first two premises would be accurate. the connection that crossdressing - an activity that 10 people engage in - is very popular or even partially overlapping with the 1M person group is completely unwarranted.

your bizarre misuse of logic could be twisted and used similarly for rapists or pedophiles or serial killers

Version 2, more sexier version!

    static boolean isOdd(int n){
        boolean [] truthTable = new boolean [n+1];
        boolean previousEven = false;
        for (boolean i: truthTable){
            previousEven = (previousEven) ? false : true;
        }
        return !previousEven;
    }

that one is O(n), i'd like to see an O(log n) recursive fib

Recursion isn't slower because of higher time complexity, it's slower because of the extra stack overhead you mong.

Cross-dressing is a mental illness that should be treated at medical institutions, not encouraged.
Meanwhile a gun hobby is manly and fulfilling. Also useful.

how about you print url before the if? that's not difficult to do or to understand, right?

>>55002178
A fascination with firearms is fine.
Thinking that every citizen has a right to use and own them, even if they're on lithium, is batshit insane.

why does python do this?

>>>a = [0, 1, 2]
>>>a[-1]
2
>>>a[3]
list index out of range

why can it loop backwards once but not twice and not loop forward at all?
how would this be useful ever?
why make it loop at all?

Not a right, but a duty. An obligation, if you will. Absolutely everyone should be armed.

>>55002275

/k/ already has crossdressers. I don't care.

print the url variable before the last if. the idea is that you'll see if it's null, or if it contains "/res/", and you should be able to see the problem.

>>55002261
in america where all the bad guys already have guns or can easily obtain guns it's the most appropriate solution

>>55002331
the appropiate solution is to REDUCE the amount of guns, so it will be a bit harder for criminals to get guns, and people/cops will become less paranoid and trigger-happy

but expecting muritars to understans logical solutions is illogical on itself

>>55002303
>>55002331
I gave the most ridiculous example I could think of, a person with severe depression owning a firearm, and you still think that's a good idea.

I hope trump wins and you all kill yourselves.

>>55002366
>le trump is bad
Opinion: DISCARDED.

>>55002366
why is that a bad thing?
he'll kill himself if anything

>>55002365
it's practically impossible to reduce the amount of guns to the point where almost no one has guns

>>55002366
shooting yourself can be a good way to go, it's better than throwing yourself in front of a train which affects hundreds or thousands people

>>55002261
I am on lithium, no bully.

>>55002395
Oh no, a merican who votes for celebrity socialites instead of politicians doesn't like my opinions, what will I do /g/?

>>55002178
crossdressing never killed anyone

>>55002451
yes it has you disgusting arrogant delusional self-centered moron

>>55002439
Trump is a better politician than anyone else on the presidential stage. His policies are flawless, prove me wrong Yuropoor.

>>55002420
>it's practically impossible to reduce the amount of guns to the point where almost no one has guns
I wasn't talking about banning guns, I don't think anyone has talked about that, but YES, you CAN reduce the amount of guns easily. in fact, it's happened a few times in my country: the govt bought them from their owners (legal or otherwise).

>>55002420
Sure it's a good way to go, so long as the person doesn't get any bright ideas to take anyone else they don't like with them.

Bit trickier to do that when jumping in front of a train, unless you just want to grab a stranger.

I love how I talk about a depressed person owning a gun, and everyone's immediate thought is their danger to themselves but not to everyone else.
Stay classy murica.

>>55002487
people would still keep guns especially the bad ones you idiot

the way you take down a bad guy with a gun is by using a gun yourself

RETARD

>>55002478
>prove me wrong

I think you'll find the only outrageous claim made here is that trump is a politician and not a socialite.

>>55002532
THAT'S THE ENTIRE POINT YOU FUCKING RETARD, PEOPLE ARE FUCKING SICK OF THE ESTABLISHMENT, WHY DO YOU THINK BERNIE IS SO POPULAR MORON

>>55002476
>>55002511
>suicide
Oh, i wonder what caused those senseless deaths.
Oh I know! A GUN

Which leads me back to my main argument.
Unlike guns, crossdressing has never killed anyone.
