>>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.

You're redefining foo in the second for loop. Any compiler will throw an error there.

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.

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

i have a project that's several thousand lines across a dozen or so source files written in python (ik, sorry).

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.

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

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.

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.

Java doesn't believe in top level functions. In any case, it's not too difficult to understand the components behind it.

A method that prints to whatever file is being held by the object it's called on.

>>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.

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.

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.

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;

using strcmp(NULL, x) is a segmentation fault. and since the while loop was going to NULL and doing the cmp regardless it resulted in weird shit.
just incase anyone was wondering.

>debating whether or not to use InitializeCriticalSectionAndSpinCount instead of the regular InitializeCriticalSection
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.

Just started SICP and I can't understand why I'm getting an error for calling my iterate function with only one argument when I clearly call it with two in mit-scheme:(define (iterate x y)
(/ (+ (/ x (* y y)) (* y 2)) 3))
(define (stopitr y)
(< (abs (- (iterate y) y)) 0.001))
(define (cubeassist x y)
(if (stopitr y)
y
(cubeassist trgt (iterate x y))))
Manually calling increment works, but the function doesn't when given a target and a guess.

Also, replace "trgt" in there with "x", forgot to include that correction in the copypasta.

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.

adding to that, browser #113 might not be a large enough program to benefit from the spin count. it only has like 10-20 threads, and there isn't usually a whole lot going on at any given time.
Is K&R bad for an absolute beginner to programming?
>>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.
>>54229194
I'd just like to interject for a moment and recommend C++ for a first language instead.
>>54229177
>you don't know anything
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.
but you're right -- I'm trying out random things, just for fun.
>>54229251
Without any reason?
I can think of quite a few reason that one shouldn't learn C++ first.
>>54229251
>recommend C++
Disgusting
>>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
And python isn't? In fact that's literally what Python is, a clusterfuck of random features.
>>54229409
I'm not advocating memesnake though.
>>54229394
>C++'s random clusterfuck often makes it easier to get work done than simpler languages (C, Pascal).
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.
>>54229422

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?
>>54228931
>what industry needs the most programmers
The one I'm currently working in.
>>54229422
I'm not going to say that C++ ISN'T verbose, but what can help is if you:
>use 'auto' as often as possible
>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)
>put things in a struct to be even more precise on what is going on
>>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.
You should prefer memes like D, Go, and Nim for real work.
>>54229544
>nim

excuse me?
>>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
No, as I've said repeatedly, C# and Java.
D will never be a thing. Go might be in 25 years, when people are trying to maintain shit written by current startup hipsters.
C and Java will be here for eternity.
>>54229570
Not saying I agree with the C++ committee, just tryna help you.
>>54229574
I was going to say D but I know that mentioning that language gets dpt riled up. However I'm willing to admit that some "real work" actually gets done in Go, even if I personally don't like the language.
