How do I understand Monads?
Need them for a Coursework.
>>54225949
Try to understand some basic examples.
debating whether or not to use InitializeCriticalSectionAndSpinCount instead of the regular InitializeCriticalSection for browser #113.
>>54225807
It's shit
>>54225986
Got any decent ones? Preferably state Monads desu
>>54225989
what's the point, what are you trying to achieve with this? why not develop an app instead?
>>54225807
fuck off hippie
>>54225989
Horrible ui
>>54226020
The Error monad is my favorite
data a = Success a | Error String
return x = Success x
Success x >>= f = f x
Error s >>= _ = Error s
map f (Success x) = Success (f x)
map _ (Error s) = Error s
It's the exception monad, and you have it in almost every language (except C and ASM).
Do you dig it?
>>54226058
>why not develop an app instead?
what? it IS an application.
what I'm trying to achieve is more performant execution.
>>54226112
if i was going to make something like that i would make somesort of machine learning thing, where it watched me as i browsed 4chan and after awhile tried to recommend me things based on threads i've been in and what i posted
>>54226143
what i mean by "things" is recommend me threads across the site, not actual things
>>54226166

that's not a bad idea. it could automatically order things from amazon, based on your 4chan browsing habits. think of what wonderous things will be on your doorstep tomorrow!

Is it bad practice if I do the following:for (int foo = 0; foo < bar; foo++) {
for (int foo = 0; foo < foobar.size(); ++foo)
// ....
}
Knowing that I won't ever use the foo of the first loop inside the second loop.
>>54225619

Try again
>>54226514
You're redefining foo in the second for loop. Any compiler will throw an error there.
anyone else can't stand underscores in code? It looks absolutely horrible to me.
>>54226586
they're way nicer to look at than semicolons and braces.

Compiles without errors on my machine.
>>54226586
Would you prefer variable names like:whatTheFuckDidYouJustFuckingSay
I mean shit, there's probably a plugin out there for whatever editor to make underscores appear in light grey or whatever so they almost blend in with the background and look like spaces instead.
>>54226664
I guess it does, huh.... Well in any case it's bad form and not the easiest to read. Just use another letter.

Hi friends, good luck with all of your endeavors. I'm doing gamedev in Unity (C#) and trying to wrap my head around enumerators (IEnumerators?). I sort of get what C# is doing in that they're pretty much always abstracted away, but it seems like Unity uses them in a weird way. Lots of fun.
>>54226735
Also it disallows using the first variable in the second scope
>>54226740
i personally prefer underscores

hey /dpt/ how do i take the next step and start refactoring my code?
i have a project that's several thousand lines across a dozen or so source files written in python (ik, sorry).
there's room to deduplicate some of it by rewriting more general code or object-orientify things, but i'm not sure what the point is
any tutorials or books you could recommend would be much appreciated, thnx.
>>54226549

I'd say one thing C got wrong was allowing underscores as the start of an identifier.
It should treat underscores like digits: allowed, but just not as the first character.
>>54227150
>Leading double underscore
C defines any identifier that starts with either two underscores or an underscore and a capital letter to be reserved by the standard and the implementation. So an implementation pretty much as to do that.

>>54225619
How and where do I get started with programming? I just want the feeling of creating the something I would actually have use for.
anybody got more of these?
>>54227524
I started on codecademy learning Ruby.
Python is also an okay place to start, but has a lot of weird fucking quirks that are idiosyncratic to it.
Learn the basics of whatever you feel comfortable using, and then IMMEDIATELY stop using that and go to something like C#, Java, C, C++
>>54227524
What would you have a use for?
need some books on developing android apps, are there any worth reading?
Apparently we actually have to talk about programming here. Who'd have known?
>>54226964
Look at your code and think of ways to make it more efficient.
Is there frequently used snippets of code to do the same thing? Factor that out into it's own method.
Are there really long script files full of spaghetti code? Rename some variables and consolidate them into separate files more organized.

Idk what the ups and downs of each programming language is, but I learned the basics of c++ in school, up to classes etc. Endgame-dream is to make games though.
I'm working on:public class Test {
public static void main(String[] args) {
System.out.println("Hello /dpt/!");
}
}
>>54227796
You could keep using C++ for games. Or learn something easier to use like C#, and then use monogame or unity to make games with it.
>>54227807
>System.out.println
Why can't a simple println suffice
>>54227724
Nah, janitor just doesn't like off topic content. I can kind of agree with that, but that doesn't mean I'm not going to be easily baited by certain types of off topic posts.
>>54227736
But there are so many other jobs that also pay shit tons. Programming really should be something you do because you enjoy it. Personally, I'm considering getting a job at Microsoft after I have my master's, and if they ask what I'd like to be doing in 10-20 years, I'm just going to give them something like "lead developer of the Windows Kernel." Because I'd legitimately find something like that pretty damn fun. Fuck management.
>>54227531

Programming is awful. I would never do it in my free time for fun. That's gay.
i want a C function to return a character, but also advance the string passed to it to the next word in the string.
i can't into the pointers for this. how do i increment the char* passed to the function?

Good luck getting that. Working on the windows kernel sounds pretty demoralising. There's been some internal chatter that no one gives a fuck about the NT kernel so long as it works. Not a lot of interest in fixing bugs or improving performance when there's a chance something might break.
That's what I've heard at least.
>>54227796
And I'm currently taking a course in C# on udemy, but it's super centered on making games, so. I'm looking for somewhere to learn C# or C++ which isn't focused on making games and such.
>>54227849
What do you mean by "advance the string passed .. to the next word in the string"?
Do you want the function to remove a word from the string?

>>54227917
C++ has std::cout
C# has Console.WriteLine
C is shit but you still have to explicitly include stdio.h and then shit like printf and puts are understood to be "reserved"
>>54227823
Java doesn't believe in top level functions. In any case, it's not too difficult to understand the components behind it.
>System
A class acting as a namespace for the standard i/o objects.
>out
An object representing the standard output file.
>println
A method that prints to whatever file is being held by the object it's called on.
So you can also do..System.err.println(stuff);
>>54227881
I've heard some horror stories as well. But hey, I like low level shit, so why not give it a shot?
>>54227901
i want this function:
1. take a string
2. find first alphabetical char
3. offset the start of the string to point to the first whitespace after the first alphabetical char
4. return the first alphabetical char
essentially, return the first letter in the string, but also "cut off" the word that the first letter was a part of. I wanted to do it this way so i could keep calling the function to get the first letter of each word in a string.
>>54227949
you can even do things likePrintStream myOut = System.out;
myOut = System.err;
>>54227949
>so why not give it a shot?
I say go for it. But I would have imagined there would be better jobs out there.. Why not Apple for example? They seem to care more about their kernel. Or red hat or some shit. I'm sure Google have some linux kernel guys too.
>>54227944

I'm proud of you anon. Keep it up.
>>54228053
no it fucking doesn't, maintainability is what matters, not the time taken to write out the code, and you can write System.out.println in no time, especially with auto complete
and most serious applications don't print to stdout for fuck's sake

It's okay anon, I think it's absolute shit :3
>>54227944
printf and puts aren't reserved, they're just a part of the standard library. But you're not required to use the standard library, and can indeed implement those functions yourself in C, especially if you want to implement the standard library yourself.
>>54227973
Why not simply return a pointer to the first alphabetic character in the string?
>>54227993
>Apple
Apple is the kind of company that takes months to fix a critical security vulnerability, and manages to fuck it up anyways. Also, they'd probably have a problem with me bringing in an Android phone to work every day.
Red Hat is a company I'd consider working for, as is Google. I've also considered Cyanogen Inc.
>>54228074
this, it's fucking babby's first webshit, it doesn't belong in a programming thread
>>54228069
You're right, most serious applications don't print to stdout.

even if they do, it's usually with some logging framework, not with System.out.println
>>54227973
What you are trying to do is very difficult, if not impossible, without the possibility of serious memory issues.
A better solution would be for the function to take in two parameters: a string and a pointer to the char you want to start your search at. Then have your function return a pointer to the next alphabetical char, which you then feed back into the function.

Stupid question here,
Does anyone know if C's strcmp destroys arrays?
>>54228254
They purposefully hold back critical updates until patch Tuesday, because publishing them any earlier would be "inconvenient".
Sounds like a pretty shitty place to work to me.
>>54228297
No. Just read the man page anon.
>>54228297
destroys the string*
>>54228297
strcmp does not modify the inputs in any way.
>>54228297
how the fuck would it, it only reads from the addresses you give it, doesn't write shit apart from the return value.
>>54228328
>>54228316
fuck if I know, but I'm trying something and when I call strcmp my inputs are destroyed, so figured I was missing something.
>>54228340
are you sure you're not calling strjew
>>54228340
Yeah, it's probably something else.
>>54228340
In sepples at least, the passed strings are defined as const so they cant be modified at all.
Gonna need to see some context if you actually want help with this.
>>54228312
I think the main reason for that is that they customers don't want to deal with updates all the time, and less so much that it's inconvenient for them. In any case, 2 weeks to a month is a much better response time than 6 months, and I can imagine with a bad enough bug, they might release earlier.
syso ctrl+space -> System.out.println();
and you're truly awful at programming if you think this is even a valid concern in the first place
>>54228404
mind checking? the only difference between it working and not working is the strcmp.int i;
char * arr[10];
...
i=1;
arr[0] = strtok(buf," ");
while(arr[i]!=NULL){
arr[i] = strtok(NULL," ");
if(strcmp(arr[i],"thing")==0)
//do thing
i++;
}
//printing arr as a general check
if I comment out the strcmp is works fine, if I leave it in the print is actually getting ignored, as well as the following code.
which in retrospect wouldn't indicate a deletion but something else and I'm just being an idiot.
>>54228475
It's not the time it takes to type it anon.
>>54228574
as for readability, it's syntax highlighted, so it's as "readable" as if it had been just println, but you have the additional visual cues of System.out so that you immediately know what it's doing
so mcfucking kill yourself retard
>>54228500
I guess I should point out that the "do thing" is just some simple assignments and prints unrelated to the array. may as well be z = 1+1;
>>54228589
Nothing you said makes any sense though.
also i'm going to bed so don't think you're right just because you have the last say
fuck you
>>54228500
>i=1;
>while(arr[i]!=NULL){
Every time you're making that comparison, arr[i] is uninitialised.
Also, use a for loop instead of a while loop.

Why would you want to use the AndSpinCount variant?
In 20 years of Windows programming, I've never once called that function. Correct is more important than performance optimized, when it comes to multithreaded programming.
I'd suggest that you only look at dicking with the spin count once you have the software working completely and correctly.

It already is, as far as I can tell. there's no major bugs and the code's execution seems solid enough.
but it'd be great if I could make it more performant with a few simple tweaks. switching over to InitializeCriticalSectionAndSpinCount takes like 5 seconds of effort. I can't tell yet, but I don't think it actually improves anything. I need to test out more spin values.

>>54229075
>switching over to InitializeCriticalSectionAndSpinCount takes like 5 seconds of effort. I can't tell yet, but I don't think it actually improves anything. I need to test out more spin values.
It doesn't take five seconds of effort. It takes a few months of effort to actually construct software that can demonstrate a benefit from such changes, and from particular selections for the spin count.
Sounds like you just want to make random changes and see what happens. Fine, but don't kid yourself: you don't know anything about why you should use that API nor what spin count would be a good idea for your particular software.
>>54227973
By now, I'm sure your requirements have completely changed and this will be useless to you. However, I wrote the function you described for fun.bool isAlphaChar(char ch) {
return (ch>='a'&&ch<='z')||(ch>='A'&&ch<='Z');
}
char firstWhitespaceAfterAlphachar(char **string) {
char *str=*string;
char firstAlphaChar=0;
while(*(str)) {
if(!firstAlphaChar) {
if(isAlphaChar(*str)) firstAlphaChar=*str;
} else {
if(*str==' ') {
*string=str;
return firstAlphaChar;
}
}
str++;
}
*string=NULL;
return firstAlphaChar;
}
Test:char string[] = "Hello, /g/. Testing, testing.";
char *str=string;
while(str) {
cout<<"FirstWhitespaceAfterAlphachar is '"<<firstWhitespaceAfterAlphachar(&str)<<"'\n";
if(str) cout<<"new string is \""<<str<<"\"\n";
}
Output:Return value is 'H'
new string is " /g/. Testing, testing."
Return value is 'g'
new string is " Testing, testing."
Return value is 'T'
new string is " testing."
Return value is 't'
So you can print the first letter of each word withwhile(str) cout<<firstWhitespaceAfterAlphachar(&str);

C Programming: A Modern Approach is top notch
>>54229147
Yes. It's very dense. It is a guide to the C language for people who are already programmers.
If you're a newb, learn Python. Then C for fundamentals. Then C# or Java for employment. Then whatever else you want (functional, JavaScript etc.).
K&R is a beautifully example of efficient writing. It's also a gold standard by which book printing should be judged (i.e. extremely high quality paper and printing). But it's not a good intro to general programming.

well I do have SOME idea of what I'm doing. I know enough to be aware of user vs kernel cpu time, and that using a spin count is probably only useful for massively multi-threaded apps that are quickly manipulating the same target.

>>54229267
I can think of quite a few reasons that one shouldn't learn Python first.
>>54229251
I'd just like to interject for a moment. What you're referring to C++ is really C with classes, or as I've recently taken to calling it, C plus classes.
Many programmers write in a modified version of the C language everyday, without realizing it.
Through a peculiar turn of events, the version of C which is widely used today is often called “C++”, and many of its users are not aware that it is basically the C language, developed Dennis Ritchie.
>>54229251
LOL, good one.
I actually went to college when C++ was hot. It was ridiculous watching CS101 types being told to just ignore all the magic behind, "cout << "Hello, world" << endl;"
That same college refused to acknowledge my AP exam scores (4/5 and 5/5) because we used Pascal... Until I met with the head of the CS department and he went, "uh, yeah, who cares what language it was in?".
>>54229326
I am recommending it because it touches on all facets of programming, and it determines whether or not you're a good programmer and can think programmatically. What other language does that?
>>54229350
>What other language does that?
Pretty much any of them.
C++ is just a clusterfuck of random features, which somehow are supposed to make the language "better".
>>54229369
To be fair, C++'s random clusterfuck often makes it easier to get work done than simpler languages (C, Pascal).
I still wouldn't learn it as a first language, though.
>>54229283
Me too. I find that there are things that make Python not ideal for learning, but I find that they aren't nearly as bad as C++, a language completely unsuited for beginning programmers.
I personally think learning a Lisp (e.g. Racket) is a great idea, however a lot of people disagree because "the industry!!" So I think that if you have an open mind you can move past some of the inefficiencies of Python. However, C++ is a complete monster of a language, with numerous features all suited for experienced programmers who are trying to write efficient code (e.g., NOT A BEGINNER). I say this from the perspective of someone who writes a lot of C++ code and actually enjoys it.
I think that implicit behavior is the worst thing a programming language can offer to beginning students. C++ is ripe with implicit behavior in nearly every feature it has built upon C.
>>54229350
>I am recommending it because it touches on all facets of programming
You have to be kidding. C++ offers nothing.
* Shitty OOP
* Shitty fundamentals in modern C++
* Shitty everything
Like I said before, Python, then C, then C#/Java, then others.
C++ just demonstrates that you can wrangle a ridiculous language with ungodly foot-shooting potential. I lived through the template-heavy curiously-recurring-template-pattern Win32 programming years. Never again.
>>54229369

Huh? You spend more time writing boilerplate bullshit than you do actually solving problems.
Not to mention the ridiculous verbosity that you hit as soon as you start using STL and actual modern C++. People criticized Java for being so verbose, meanwhile I'm over here writing std::map<ID_NUMBER, std::list<TRANSACTION_RECORD> transactions;" looking bullshit all the time.

So... You're basing your recommendation on what is the best for contrived *competitions*? Am I understanding you correctly?
You're not looking at suitability to learning. You're not looking at suitability to industry. You're not looking at efficiency at various program sizes. You're literally basing your recommendation entirely on what you think is a good language for academic programming competitions? And ultimately on a single Quora answer?

I'm not going to say that C++ ISN'T verbose, but what can help is if you:

>redeclare types with the 'using' syntax to make things shorter and more clear
>specifically, I declare nearly all of my std::shared_ptr<>/std::unique_ptr<>'s with 'using' (DESU i wish those fucking smart pointers weren't so goddamn verbose)

>>54229451
Don't listen to the conformists who tell you to over-refactor.
If it's clear what your code is doing in all of those loops, then do it. Make sure it's not likefor (int i = 0; i < s.length; ++i) {
int k = 0;
for (int c = 0; c < i + k; c++) {
for (int j = i; j < s.length; j++) {
if (s[i] == s[j] + c)
k = 1;
else
j--, c++;
}
}
}
>>54229507
No, I was answering your rebuttal retard. You said you spend most of the time on boilerplate. If that was true then why would competitive programmers use it?
>>54229480
>That's the price you pay for templates and nice data structures being part of the standard.
No, that's the price you pay for a shitty parsing system and a standards committee that moves at a glacial pace.
C++ would have been much more tolerable if the auto type keyword had existed 15 years ago, but it didn't. And ranged for loops. Instead, we had mind-numbingly repetitive code in which substantial bugs could easily hide.
>You don't get map OR list in C.
Which is why you use Java and C# for real work.
C++ is C that tried to be better for larger projects. It became a nightmare. C# and Java are far superior for large projects, and C is superior for small, tight projects.
>>54229535
>Which is why you use Java and C# for real work.

>>54229544

>>54229520
> >>use 'auto' as often as possible
Uh, fucking NO. auto is for very specific circumstances. It should only be used when the return type can be easily inferred from the following code.
>>redeclare types with the 'using' syntax to make things shorter and more clear
Ah, yes, more overloading of existing keywords because the retarded committee favors unreadable code over ever possibly breaking anyone's compile, ever, by introducing a new keyword.
>>54229552
You objected to Nim from that list?
>>54229544

C: yes.
Java: no. There will come a point when the maintainers will get so tired of exception stack traces they're just rewrite entire codebases (or wrap them in such a way that they don't need internal changes) to not have to deal with it any more.
C on the other hand really is here forever. People always complain that C is unsafe, but even if that is true, things are nowhere near as bad as they are going to become.

The lambda you pass in compares the two strings, returning and 'int' to tell the sorting algo which string comes first. negative nums means the lhs comes first, positive means rhs and 0 means they are identical strings.

If that byte isn't wedged inbetween other bytes, it probably isn't worth it. Even then, it probably isn't worth it.
Most architectures do a thing called "alignment" where they keep all of your data fixed to 4-byte segments; it actually helps performance. So e.g. in a function like:int foo () {
char x = 'a';
}
the 'x' variable is actually going to be receiving an entire word (4 bytes) of space on the stack, in order to preserve alignment.
Coercing the time duration into a single byte is going to cause you hell when you have overflow errors.

Amy 59 69 79 89 99 395 79 C+
Brenda 58 68 78 88 98 390 78 C+
Catherine 50 60 70 80 90 350 70 C
Diane 57 67 77 87 97 385 77 C+
Emily 56 66 76 86 96 380 76 C+
Fred 55 65 75 85 95 375 75 C+
George 54 64 74 84 94 370 74 C+
Henry 53 63 73 83 93 365 73 C+
Ian 52 62 72 82 92 360 72 C+
Jane 51 61 71 81 91 355 71 C+

Thanks guys. I was really stuck on that.

Uh... maybe I'm misunderstanding you, but if the instructions for your assignment say to use a char array (the standard way of representing strings pre-C++,) then you should probably use them, rather than strings.

It's simpler than a string. Technically, it uses slightly less memory.
I use them in my C++ programming because I prefer to use a C-like subset of C++ features, and I enjoy working with them more.
There's something satisfying about working with a simple, raw array of ascii bytes.
char names[3][MAX_NAME_LENGTH]={"Amy", "Brenda", "Emily"}; is hardly a strange way to do it.

Homeworkboy back for more answers. Anyone care to help me with this one? I am just going to Bing it anyway. I have to make the answer at least 250 words, which sucks.
>Q2. What are the advantages of using arrays? How static arrays and dynamic arrays differ? State one real life example where static arrays may be used.
>>54230662
That's easier thanstd::vector<std::string> names = {"Amy", "Brenda", "Emily"};
?

>needing a logging framework
Your generic stdlib logger is fine for 99% of cases.
>>54230754
Easier? Neither option presents any difficulty, really.
It is simpler, however. And it could have better performance characteristics.
In fact in your example, you are using a dynamically sized object (string) inside another dynamically sized object (vector), when a much simpler fixed-size char array will suit your requirements perfectly.
The differences won't matter for a simple homework assignment, but if you were instructed to use char arrays (a perfectly reasonable decision, and in some ways, a superior one,) then you probably should.
>>54230662
>char names[3][MAX_NAME_LENGTH]={"Amy", "Brenda", "Emily"}; is hardly a strange way to do it.
That uses unnecessary memory.
In C++ where the hell should you put your constants? Should they be in the cpp or the header?
>>54226904
You can make desktop apps with Python, but they'll require a Python interpreter to run, the same way Java requires a Java VM, plus, your code won't be a fucking eyesore
>>54230932
I think you can put them in either. I just put them in the cpp file usually.
>>54230968
There are tools that convert python code to binary so the user doesn't need an interpreter.
>>54230890
That's true. However, std::strings have more memory overhead.std::string sNames[2] = {"Amy", "Brenda"};
char charNames[2][16] = {"Amy", "Brenda"};
cout<<"Strings: "<<sizeof(sNames)<<"\n";
cout<<"Chars: "<<sizeof(charNames)<<"\n";
Strings: 64
Chars: 32
So for this application, using my fixed-size array will be half the memory of the std::string method.

Compile time constants (using constexpr or #define) can be put in either the source file or header file, depending on where they are needed.
Constants that use const should not be placed in the header unless given explicit external linkage, as they are default static. Otherwise you're duplicating data in the generated binary.
>>54231018
Yeah but you're using MAX_NAME_LENGTH (which isn't portable btw)
>>54231101
That's intended as a user-defined constant. In this case, I'm setting it to equal 16. We can even bump it up to a generous 32 and still be as good as the std::string in memory usage, and with the benefit of a much simpler, easy-to-debug data structure.
It's true that this is less general than using resizable strings, but if we have prior knowledge of the dataset, it's not unreasonable to use such a constant, especially when performance is a consideration.
>>54231134
Okay I see. I agree but in most cases where I'm not obsessing over shaving off bytes I'm gonna use string because of the useful member functions it provides.
I wanted to be able to download from Bandcamp without paying, so I wrote a shitty program to do it for me.https://github.com/ltnublet/BandcampDownloader1/blob/master/BandcampDownloader/Program.cs
It's so bad that I don't even know why I'm posting it, but it works so I don't care enough to do it properly.
>>54231018
Bear in mind that you're not even seeing all of the memory used by the std::string. You're seeing 32 bytes per string, but that's only the stack memory, which should contain a pointer, a length field, a capacity field, and something else. Then you've got some heap memory for the string, probably 8 bytes for each of those strings, plus another 8 bytes to tell how long the heap allocation is. So in reality, target than using 64 bytes for 2 strings, it's more like 96.
But what you sacrifice in memory usage you gain in convenience.
>>54231272
Ah, good point. I wasn't sure whether small std::strings used heap memory - I thought I recalled some kind of clever overloading of stack data for small strings.
>>54231264
What kind of bitrate are you getting?

128, it parses the album page to find the paths to the mp3s for their web player thing. I'm assuming that the path isn't the same for the load balancer for stuff like flac (I tried naively changing the encoding flag from mp3-128 to flac, but it gives an error about how the download failed).
>>54231406

I'm no music snob, but even I have a hard minimum of 192.
>>54231416
Such is the price of free
>>54231325
That would be one way of implementing them. But having to constantly check with every method whether the bytes are heap out stack allocated would introduce some serious runtime overhead. In general, I'd say speed > space.
>>54231425
It seems like the quality is based on a token. Changing the enc parameter returns a server error
>>54231556
I noticed that too, but those poppler links seem like they're some sort of load balancer, and they don't play well with changed the encoding flag (which is probably intentional, I'm sure that I'm not the first person to try to download the sonds without paying).

I actually think this is quite beautiful. It's not really tuned for human beings though. If everyone had to program like this we would probably not even have compilers yet.
