hey /dpt/, when applying to a job, how do you respond to the questions asking you for your motivation to work in the companies?
I just write "I want to learn blahblah and I want to contribute with my skills and knowledge". what should I write instead?

This doesn't seem programming related. You will almost always be asked to send a resume and not fill out some online job application where 9/10 applications are purposefully sent to /dev/null.
Is it better to focus on one language only when programming? I've been learning C/C++ because I thought since they were in the same family it might be a good idea to just learn them both, but the subtle stylistic differences trip me up sometimes, and implementing solutions in OOP and procedural programming is a wee bit of a strain on my brain.
I guess I was wondering because I'd also like to learn a little bit of x86/x64 assembly. Should I stick with just C/C++ for now?
>>54370278
fucking HR fucks
Just look for something you might like on that company and accentuate on it.
>>54370313
I would follow one and then flow to the other, they're different approachs. Also C++ has way more features than C. With what I know now I would.
C -> asm -> C++
>>54370253
If you do shit like walking a tree with iteration, You should straight up kill yourself.
>>54370313
C and C++ are completely different languages, and under no circumstances is it useful to think otherwise.
Just learn C.
>>54370313
I'd say learn what you need and avoid anything superfluous. I mean, what do yu need C / C++ for? Anything in mind yet? How would ASM benefit you?
I'm reading The Go Programming Language right now, and while I eventually understand every example, it really sucks that I can't explore individual functions further in some kind of REPL. I have to construct an entire program around that case and compile it. It feels like I'm learning at a snail's pace.
>>54370353
Learn C because everything is C. Learn an asm to understand C.
>>54370313
You should focus on one language when you are just starting, but it is of worth to learn multiple languages as you progress. As for wanting to learn assembly... you can learn that in tandem with C and C++. In GCC, if you compile with the -S flag, you can get an assembly output to see what exactly your code translates to. Something I would encourage you to do is to dig under the hood and see how crap works as much as possible. It is both fun and enlightening to see the ugly internals of programs.
>>54370253
>compiler abuse
No such thing. If you know your compiler will optimize it, you should always use whatever is most convenient. Sometimes that's a for loop, sometimes that's a tail recursive call.
>>54370316
HR is a self-perpetuating meme.

Whenever I want to remove an item from a singly-linked list, I pop the entire linked list to a temporary array and then push every item back minus one item.
It's much easier to think about than writing edge cases for keeping track of the previous node when traversing a linked list and then decoupling it by hand.
>>54370410
God damn, that is stupid.
Also, you can easily avoid edge cases by using pointers to pointers.
>>54370410

>>54370327
This is kind of what I ended up doing anyway. Classes are a pain considering most of my projects are very small. That being said, I thought templates were a really cool feature of C++.

but isn't C++ a superset of C?
>>54370353
don't tell anybody, but it's for gamedev. Also, I'd like to make custom video game hardware, because I've been kind of dissatisfied with the low quality controllers I find these days, so I want to make the greatest controller ever, so I'm kind of looking to attain an extremely fluent understanding of driver software / hardware interfacing, and I've heard assembly is used for that.

Any regex wizards here?
I've got this:\[url=(?:")?((?:https?:\/\/)?[^\s<>"]+|www\.[^\s<>"]+)(?:")?\](.*)\[\/url\]
The quotation marks are supposed to be optional, and it's working fine for the opening one, but it captures the closing one even though I'm using a non-capturing group, so this:[url="something"]asdf[/url]
Will yield:something"
asdf
But I want only something, without the ending quotation mark.
Another issue is that I use something like this for spoiler tags:r'\[spoiler\](.*)\[/spoiler\]
However, when I have multiple spoiler tags it will match everything in between the very first opening tag and the very last closing tag, I guess it has to do with me using (.*) but I'm not sure what'd be a good pattern to match almost all the stuff.
Fugg, I'm getting all these offers for web dev jobs and I can't take them because pretty soon Squarespace will replace the front-end and I'll be out of a job.

Doesn't sound like a bad plan. I mean, for gamedev I would really go for C++, but you'll be fine with C. In fact, it's even better that you'll be focussing on lower level code which is more appropriate for what you're ultimately going for.

>>54370452
C and C++ are different languages, but a large subset of C is also valid C++. This subset of C is large enough that libraries can be written in C that are usable in C++ using the same header files. That said, you should note that not all C is valid C++, and a lot of C++ is not valid C. Furthermore, it is not wise to program C++ as one would program C, because there are a number of features in C++ that are particularly useful, with no cost to the programmer whatsoever. That does not mean, however, that one needs to use every feature of C++, or that one should prefer the C++ standard template library over other implementations of various data structures (std::string is convenient at many times, but not always the best solution for a string class).

I've been hunting for a job for a month and I still have nothing to show for it. Why is it so hard to get a software developer job /g/?

>>54370585
is that equivalent toint j[5] = {};?
>>54370642
>int j[5] = {};
That is automatic memory (stack allocated), while the other is dynamic memory.
Also, there is supposed to be a 0 inside the array initialiser.
>>54370639
Where do you live?
>>54370642
no, in C++98 and C++11 its the uniform initializer
new allocates memory on the heap and returns a pointer to it, calling the ctor directly allocates it on the stack
>>54370656
{} does aggregate initialization here, which you do have to eventually call the value initialization (0 for your example)
but in c++11 you can just doint j[5] {};

Make a wrapper struct.struct forward_list {
struct list_node head; // Head node contains pointer to first node
struct list_node *last; // For easy insert at end
};
>>54370799
this is literally spaghetti code
>>54370799
It's still a special case.
The non-retarded way isvoid list_remove(struct list **head, int n)
{
for (struct list **curr = head; *curr; curr = &(*curr)->next) {
struct list *entry = *curr;
if (entry->val == n) {
*curr = entry->next;
free(entry);
return;
}
}
}
>>54370807
Anon, that's just a simple wrapper struct. Idea is to call remove_next on the forward_list's fake "head" to remove the first node from a list. Of course, if you don't like that option, an alternative might be to have a separate function for removing the front:struct list_node* remove_front(struct list_node *node)
{
struct list_node *tmp = node->next;
free(node);
return tmp;
}
>>54370901
>>54370887
or you know...
you could simply dump the entire list to an array and then push it back?
that way you don't have to maintain dumb exceptions and "fake head" pointers to maintain consistency in your linked lists
>>54370915
My two-star code doesn't have any exceptions. It will work if you give it the head, the tail, or any other element.
>>54370219
Why doesn't this code work? It doesn't print the concatenated string.void string_cat (char *destination, char *source)
{
while (*destination != '\0') {
destination++;
}
while ((*destination = *source) != '\0') {
destination++;
source++;
}
printf("The concatenated string for 'this_string' and 'that_string' is %s.", destination);
}
>>54370932
>printf("The concatenated string for 'this_string' and 'that_string' is %s.", destination);
Because destination now points to the end of the string.
Print the string outside the function instead.

>O(n) removal of elements from the middle of a list defeats the purpose of using a linked list in the first place. You have substituted one bad solution for another.
You can easily generalise the code to scan over the entire list, deleting nodes which match some predicate, or only delete the node currently being pointed to.
The whole point of it is that double indirection is better than single indirection.
Is the extern keyword in C only required when you want to be able to access a variable in a file that is included via the preprocessor? When I tried it with two source files I just compiled together the variable had the same address in both files even w/o the extern keyword. How?
>>54370901
>Of course, if you don't like that option, an alternative might be to have a separate function for removing the front:
Or just have only that function.
remove_front() will work for all nodes.
Just applied for another round of jobs. Now to wait till tomorrow when a single one of them will wake me up with a phone call and then never respond again afterwards no matter how charming or knowledgable I come off
>>54371108
>The whole point of it is that double indirection is better than single indirection.
Linked lists with one level of indirection is bad enough, you just made it even slower.
>>54371160
>you just made it even slower
Do I didn't. You only need the double indirection when walking the list.
You have the pointer to the pointer to the node. That's already with the node, so you don't have any worse locality.
>>54371184
To get to entry-val you have two levels of indirection.
>>54371108
Fair enough, but given that this is the kind of idiot to destroy an entire linked list just to remove one node, it would probably be best to actually provide an implementation that uses predicates, instead of just "delete nth node"
>>54371125
Yes, and then it's the caller's responsibility to make sure that the previous node's next pointer isn't invalidated. Not entirely ideal.
>>54370330

C++ started out as a superset of C, but rapidly evolved into a whole different beast.
You can 'code C in C++' but that's about it.
Basically:
If you want to program kernels or AAA vidya gaems, learn C++.
If you want to program uControllers and high performance programs, and also just gain a very useful language that makes it easy to learn all other languages (you'll basically just have to add OOP + functional programming) and runs on everything(tm), learn C.
>>54371280
If a function is tail recursive, it will never cause stack overflow as long as the developer isn't a retard who forgets to turn on optimization flags.
If a function isn't tail recursive, there is an implicit stack. An iterative equivalent would have to create a stack data structure on the heap to store backtracking information. This stack would necessarily have to be able to grow (if you could put a bound on the amount of memory needed, you could just use normal recursion and request enough stack space), and could run out of memory just as one could by running past the end of a call stack. The end result is the same.
>>54371477
I was using the wrong variable. I was supposed to print the string that was concatenated, not the pointer.
It kind of looks like unless I start a company all on my own I'm shit out of luck in the jobs department

The explicit stack is better because you avoid function call overhead.

>>54371814
in a reasonable program you will know ahead of time the size of the tree or an upper bound
>>54371854
In which case there is nothing wrong with using recursion, because you can always increase the size of the stack to however big you need it to be.
>>54371924
it's not even unintuitive at all to use an explicit stack for tree traversal

You should be able to tell me what this code does /dpt/:template<typename T, size_t N>

return N;

What the fuck is const T(&)[N]? A reference to a const function that take an array of size N?

It's not. Regression is a perfectly normal defense mechanism and occurs naturally when it comes to things like achieving orgasm or being creative. It can, however, indicate an underlying mental health issue.

kill yourself retard, there is no reason to think it's wrong, i tried all the relevant cases and because of how the code is designed it should hold for all cases and platforms, you're the one that claimed it's wrong, the burden of proof is on you
Working on a small program in C++/Qt. It basically needs to display logs, messages and various stats from a game engine a friend of mine is creating.
Doing things slowly, it uses tcp to communicate with the game. I'm mostly having fun with Qt and its stylesheets.
>>54374419
>>54374434
you only need to provide one (1) example of input that it produces the incorrect result

Has anybody here tried to use GPU acceleration for calculate heavy tasks?
>>54374666
You spelled "DX12" wrong.
I came to a /dpt/ yesterday to ask a couple of questions and found that there's no information at OPs post, like in other threads, as /flt/.
As I know nothing, I barely can contribute. I'll post a couple of infographics I have if they somehow help.
>>54374640
It's linux, I'm trying to cross-compile.
How do you know what parts of the program to separate into files?
I have a "graphics.hpp" that handles graphics, but my main engine file handles all kinds of shit, weapon classes, collision triggers, explosions, AI logic, physics.
Should I just make them into "weapons.hpp", "physics.hpp", "AI.hpp"? I heard seperating a project into multiple files is inefficient.
>>54374683
Altcoin mining.
Didn't program it though.
It was pretty tedious 5y ago, don't know if the new API got any better.
Minefield of gotchas, tho. What do you want to speedup? There are only limited domains of problems that benefit from GPUs, you need to be able to reduce it to matrix calculations/linear algebra.
>>54374762
What information would be relevant to the OP?
Beginner languages?
Best languages?
Good resources?
No one can agree on any of this.
>>54374768
maybe try including the lib path directly and see what happens
>>54374683
Of course faggot
Its not effective

You can start literally anywhere. I started with JS and Perl, probably the worst possible way to start, but I'm working in C++ pretty much daily now.

I don't want to throw errors every second line of code.
Off topic, but still semi related. Does anyone here use a Sceptre U435CV-U as their monitor? Lag isn't a big issue for me, I don't gayman on my desktop. But text is very important because all I do is programming and shit post. I would like to get on the 4k productivity level.
>>54374795
I see, so the problem is that there is no agreement betwen programmers?
well, at least there could be a little something so people could read before posting. I know nothing about languages but I heard that python is easier than other languages, that is something.
>>54374863
>Sceptre
sounds cheap and shitty
lag should be fine since it probably doesn't have fancy processing gimmicks
the main concern should be if it's IPS and high quality (like no uneven backlight and clouding and shit) and also the stand which is presumably the most basic shit with just tilt forward/backward
count on having a few dead/stuck pixels
>>54374779
There's no exact science to it.
Just group together things which makes logical sense.
There are various tradeoffs between readability, needing to include too many headers, splitting code up to much, etc vs extra compilation/preprocessing times, but they are very minor tradeoffs at the end of the day (unless you have millions of lines of code), so don't fret too much over those things and focus on logical and semantic structure of the code.
>>54374762
>Python
That infographic is very outdated and written by a Python shill.
>>54374847

>>54374938

(You)
>>54374887
Yes, but learning Python first can inhibit your ability to learn other languages, especially C-like languages like C#, C++ and Java.
Your learning language should likely match the industry or particular applications you wish to pursue.
For example, you would likely use C in embedded systems and kernel development, but you wouldn't do the back-end of a website or most enterprise applications in C.
If you want to learn to make mobile apps, you would probably be better off jumping right into Java or C#, as both of these can work on Android or iOS.
The good thing is that most of the Big 10 can be widely used across many platforms, and your language of choice will end up being your own personal preference. While some languages have strengths in particular industries and applications, most (high-level) languages can be used for just about anything.
>>54374959
>K&R
It's "the C programming language" book.
If you can't google shit you won't last long in programming.

If I wanted an answer about muh input lag on battlefield 12 then I would have asked there.

From what I've seen on reviews, the backlight is even. The panel is an lg RGBW IPS. Just wondering if anyone here writes any code on one.
>>54374984
So, you are telling me there are different "tiers" for languages?
>>54375003
I asked you because K&R is pretty inespecific, but you are right, just googled it and it was like the second or third link.

>Best languages?
Depends on what you want to do.
>Good resources?
Depends on the language.
>No one can agree on any of this.
That's because they're all relative to the individual.
There is no "best" language.
>>54375132
I see, so as the tools there are more specific languages than others, some of them are more versatile.
>>54375171
neat, have you thought of adding suggestions? like the more you download images with curtain tags, it starts to recommend those or put them higher on the list of search results.
Would be nice if it knew which you already downloaded so you don't see those again
>>54375188
nope, running linux. but what >>54375132 said was useful, if you think of languages as tools, the better tools will depend on the work you must do. and depending on the work you want to do you will need more specific tools (languages). So a surgeon and a plumber will have their respective tools, but they are not barely related.
>>54375214
Well it has a tag history, so if you search a tag once it gets put at the top of the suggestions. Honestly I don't see the point in hiding posts that you've already downloaded, though maybe there could be an indicator that you've already downloaded it

i guess i will wait a while and then probably end up actually doing it since it's well within their rules and not illegal or anything, it's just a bigger discount and more lost revenue for them than in the average case

The whole software industry is held back because of people like you. Please don't ever reproduce and, if possible, kill yourself with fire.
This said: the recursion is the loop as it is mathematically defined, and it is a lot more flexible then the iteration. It avoids so much retarded bugs it probably could save a lot of companies. Also, a compiler/platform that is not written using a pen in the programmer's ass optimizes this (including TCO). Yes, I'm looking at you, JVM. Scala had to implement it in its compiler, while Clojure had to write a function to cope with the oracle's devs retardedness.
Yes, I'm mad.
>>54375245
if you hide them, they won't take space and time to scroll through, you could alternatively put them in the bottom or as you said, just place an indicator that you've downloaded them
>>54375266
>a lot more flexible then the iteration
bwahahahahahaha
>>54375266
iteration can do anything that recursive function calls can do and recursion is literally deadly
>>54375281
Good point, ill probably make it a preference later on
>>54375311
but this may be optimized! Look at SBCL, Haskell, Scala... They do not eat as much stack as C recursive calls do, and they make heavy use of it. It's 2016, we have TCO
