WriteLine($"Input {lineCount} " + (lineCount > 1 ? "lines" : "line" ) + " of text now. Strike the return key after each line.");
foreach(var x in Enumerable.Range(1,lineCount))

Does anyone with experience in networking know how to check if a UDP datagram was sent by a client to a server in C? I can currently receive datagrams from clients with recvfrom (), but what I really want to do is check if a message was sent on the UDP socket, and if a message was not sent then I want my program to continue running instead of waiting. I tried using the MSG_PEEK flag as a way to check I'd there were any messages on the socket, but this isn't really working for me. I've done a lot of googling for the past 8 hours and I cannot find anything which can help me, and stackoverflow posts aren't helping me with the question I have.
Does anyone here know what I should try next?

Problem is, this is one of the few times where I don't think I'd want to LINQ it up, as your LINQ only replaces the one foreach statement.
In this case, I think it's much easier to read the non-LINQ:foreach (var line in lines)
{
var tempLineCounts = line.Select(x => x.Count());
foreach (var word in tempLineCounts)
{
if (word <= 10) counts[word - 1] += 1;
}
}
vsvar counts =
lines.SelectMany(line => line.Select(w => w.Length))
.Where(x => x <= 10)
.Aggregate(new int[10], (acc, val) => { acc[val - 1]++; return acc; });

I actually installed appchan and I don't see a problem.
How often do you guys, outside of your job, write down a pseudocode of your algorithm and then implement it the language you are working in.
Today I have the attention span of a toddler, so I wrote down on a piece of paper what I want to do. I don't make programs on my own volition often, but it's the first time I did something like this.
>>53806066
I have a dry erase board that I sketch out basic class design and interactions between GUI and logic.
It's usually simple stuff, but just enough to have a 10,000 foot view of what I'm about to do so I can see if it's retarded.
>>53805850
wrong, it obviously just passes the reference to the array around
>>53805818
What are you trying to do here and what are you having difficulty with?
>>53806066
Literally never. Pseudocode is for plebs.
Sometimes I'll sketch out the logic for a program/algorithm in basic terms of the language before going back and redoing verbose portions in more detail, but if I was going to write pseudocode I'd just use Python instead.
C++ question from a self-taught C n00b:
I have a class I've written that I want to be able to read into from a stream. The stream will be text, and the data for the object will be fairly simple. I can think of a fairly easy solution using scanf, but I want this to work with streams.
My current approach to simple parsing is to first store the position, then attempt to parse one or more desired values, e.g.// semi-pseudo code
bool successfulRead = false;
String openV = "<";
String closeV = ">";
String sepV = ",";
float fVal;
int iVal;
while( readWS() ); // readWS() returns true and advances the position when it reads a whitespace character
if( !readMatch(openV) ) // readMatch(openV) returns true if opening string was found
return FAILURE;
while( readWS() ); // discard possible whitespace before first value
if( readFloat(fVal) || readInt(iVal) )
successfulRead = true;
else
return FAILURE;
if( !readMatch(sepV) ) // read for separator for other (optional) members
.
.
.
(etc)
The idea being that I can easily deal with optional items because the read functions would advance the stream pointer if they succeeded, or leave it untouched if they failed. I am not sure how to fit that with C++ streams that will work with any stream.
I am more than willing to admit that I know little about parsing, but the task is really simple and I'd rather keep the hassle to a minimum (preferred no libraries or std library, but willing to do what it takes).
Background data:
I am reading vectors (math) from a text file. The vectors can have anywhere from 1 to 4 elements, and the opening, closing, and separator characters may vary, and white-space is ignored. Examples:<1,2,3> // valid
< 1 , 2 , 3 > // identical to above
[[1, 2, 3]]
[(1, 2, 3, 4 )]
(etc)
The open/close/sep/WS strings are consistent within the file, and known beforehand. For the super-curious, this is for POV-ray Mesh2 objects.

Is it bad practice to just throw code at the wall until it works?

>>53806140
Depends on your school of thought. There are entire disciplines of programming that believe that you shouldn't write a single line of code until you have every aspect of the entire program planned out in minute detail. There are other disciplines that say you should start with a vague idea of what you're doing and just code until it works.

>>53806190
I prefer to figure it out as I'm going along. I find it easier when treating it like a sculpture, ie you start with an ill defined blob of nothing and gradually carve out the intricate details until you have code that works. Problem is I am really shit at optimization so my code usually ends up being an enormous pile of if statements, but it works which I suppose is the main thing.

I'm trying to make an little program to calculate the mean deviation of values in a array. I got stuck in the variance as it return values near what they are suposed to be but not exact. FOr Example variance=4,33 it gives =4.7. Can you take a look and try to help me? Needless to day I'm new to coding.#include <stdio.h>
#include <math.h>
int avr(int a[],int siz){
int i;
int sum = 0;
float mean;
float vari=0; /*variance*/
for(i=0;i<siz;++i){ /*calculates the mean value*/
sum= sum +a[i];
printf("%d\n", sum);
}
mean=sum/siz;
for(i=0;i<siz;++i){ /* calculates (given values)-(mean), squares that result and stores them in a array*/
double dif[siz];
dif[i]= pow(a[i]-mean,2);
for(i=0;i<siz;++i){ /* adds the squared values and assign variance to be them/siz */
double temp=temp+dif[i];
vari=temp/siz;
}
}
printf("The mean distance (variance) of the given values to %0.2f is %f\n", mean, vari);
}
>>53806173
Yes, thank you dear.
But, the problem is that the tell and seek function do not work with all streams, especially with cin or cout. I was hoping for guidance with examples when it comes to parsing stream input. Insight involving strings and streams, possibly including string-streams or the like would be appreciated, but my main problem is how to do things in the "proper C++ way" when it comes to using C functions like scanf and strtok.
>>53806091
I thought all the states and behaviour of a printer belongs in a class, but right now I am "programming" a clusterfuck of behaviours in the main class and made even a mainmenu in it.
But I am disgressing:
I am trying to make the printing steps work and make program go back to the mainmenu.
Either after the user doesn't want anymore, or the maintenance counter I placed in class reached 15 and informs the user of the problem, leading him back to the main menu.
Also Shouldn't the mainmenu be in the printer class and shouldn't the mainfile just create the objects and make it run?
Sorry again, this is my first time after a veeeeeeeery looong time of dabbling.
>>53806140
honestly depends on your goal and time frame, but most of the time I feel I waste less time if I spend a little time planning the structure of what I'm going to write
>>53806397
For the most part, classes shouldn't ever have user interaction like with menus and input. They should simply have functionality.
The setup you have now is fine.
You'll need a while loop around the main logic of your program to do that.
>>53806213
Premature optimization is bad anyway. What you should do is learn some design patterns and techniques for abstraction.
I start a project by just banging out code, and if I start noticing any code smells like repeated code or nested ifs, I'll refactor before I get too far. If you get quick at refactoring, just banging it out isn't a terrible way to start.

>>53806654
Not convinced at all. If one want to program, he need to have a good grasp of logic and abstraction. For that you already have top notch materials like sicp htdp or csforall. There already pl suited for total beginners: scheme, scratch (code.org). The code example is shit.

You may think this would make it difficult for non-English speakers. But consider that there are a myriad of other languages you could use, for this purpose, and choosing any one of them would still be difficult for people who don't speak that language.

>>53807683
he most powerful programming language is Lisp. If you don't know Lisp (or its variant, Scheme), you don't know what it means for a programming language to be powerful and elegant. Once you learn Lisp, you will see what is lacking in most other languages.
Unlike most languages today, which are focused on defining specialized data types, Lisp provides a few data types which are general. Instead of defining specific types, you build structures from these types. Thus, rather than offering a way to define a list-of-this type and a list-of-that type, Lisp has one type of lists which can hold any sort of data.
Where other languages allow you to define a function to search a list-of-this, and sometimes a way to define a generic list-search function that you can instantiate for list-of-this, Lisp makes it easy to write a function that will search any list — and provides a range of such functions.
In addition, functions and expressions in Lisp are represented as data in a way that makes it easy to operate on them.
When you start a Lisp system, it enters a read-eval-print loop. Most other languages have nothing comparable to `read', nothing comparable to `eval', and nothing comparable to `print'. What gaping deficiencies!
Lisp is no harder to understand than other languages. So if you have never learned to program, and you want to start, start with Lisp. If you learn to edit with Emacs, you can learn Lisp by writing editing commands for Emacs. You can use the Introduction to Programming in Emacs Lisp to learn with: it is free as in freedom, and you can order printed copies from the FSF.
You can learn Scheme (and a lot of deep ideas about programming) from Structure and Interpretation of Computer Programs by Abelson and Sussman. That book is now free/libre although the printed copies do not say so.
Please don't buy books (or anything) from Amazon!

no matter what your opinion is about java, you're retarded if you don't think C# is worse than java.
C# is literally a cargo-cult clone of java with massive feature-creep due to a load of dunning-kruger pythonesque "features" tacked onto it that you aren't even supposed to uses
>many of the drawbacks of java
>many of the drawbacks of C++
>few of the benefits of java
>few of the benefits of C++
java is good for its simplicity and ability to scale to large applications. if you don't need simplicity you may as well use C++ instead. the "low level features" in C# still give you shit performance.
>>53807990
Agreed. But there's no reason to use Java over C#.

Using Count() on a string is the dumbest shit. Also, it crashes when you start or end a line with whitespace.
>>53808006
The best reason to use Java over C++ is all the jobs these days are all in Java and if you want a better chance of making good money you should learn Java
>>53808042
>i'm too stupid to understand anything but fizzbuzz-tier C
Reminder that ANY company that wants high performance will not let you use Java
Reminder that ANY company that wants security will not let you use Java
Reminder that ANY company that wants good code will not let you use Java
Reminder that ANY company that wants quicker development will not let you use Java
in C you use structs and functions which operate on structs. languages with OOP are basically the same thing but with much cleaner syntax
>>53808034
There are only three operating system that are used by non-autistic people: Windows, ios, android. c# works great on all of these.
>>53808075
>java is too hard for me to learn :'(
>>53807863
Ignore language recommendations. It doesn't really matter what you start with. Any of the big ones (for which there is plenty of learning material) will do. Essentially you want to learn to program, to think about problems in a certain way and come up with solutions for them, rather than learn the syntax of some language. That is the skill that gets you hired.
>>53808083
>ios

java works great on all of them

it DOES matter. at the very least it should be a statically typed language. this means NOT python. python is SHIT

Java is very popular for a good reason.
Even NASA uses Java
>>53808112
Better than an android device.
>>53808034
What? No. Not remotely.
C# with ASP.NET is one of the larger web frameworks around.
There's also GTK# which can be used to make Linux apps, and Mono which works on Android as well as Linux.
And then there's that one operating system that's being written in managed C#.
>>53805279
what's better: matlab or any of the alternatives mentioned on wikipedia? (GNU Octave, Scilab, FreeMat, Julia, or Sage)
I'm going to do some tests on algorithms for controlling stepper motors
>>53808031
>Frameworks/libraries
true, depending on what you want to do. I've never come across anything i wanted a Java lib for in .NET. It's math and database stuff Java has the edge on right? I do a lot of UI on desktop and mobile. .NET is hard to match for that.
>mono fucking sucks and is slow btw
True. There's also coreclr now.
>speed
depends what you're doing. CLR supports pointers, SIMD and easy native code interaction. There's a lot of ways to make up the raw performance gap.
>reliability
hmm?
Generally I find the advantages of C# far outweigh those downsides. It's nice that coreclr and mono are both MIT licenced. Xamarin is awesome. Working generics is nice. Properties. SIMD. Structs. Good native interop. ASP.NET. MonoGame. Unity. Async functions.
Just as a raw language though, it's hard to say Java is better than C#. C# is basically a clone of Java that fixed all the problems in Java and added a few other nice things.
>>53808075
Then why are all the jobs and most corporations all use Java? Checkmate this Java is not good meme it seriously needs to stop

>>53808127
For me personally Sage was enough (I was doing some basic shit with graphs and calculus)
But it seems that most of more math-heavy oriented people shit on all oss math software and prefer matlab
>>53808107
How does static typing help you learn programming better? It doesn't. Fuck off with your autist advice.
>>53808128
>depends what you're doing. CLR supports pointers, SIMD and easy native code interaction. There's a lot of ways to make up the raw performance gap.
it's still fucking slow even with these things (which require a lot more effort for no gain). use C++ if you want performance.
>>53808178
easier to go from static to dynamic than vice versa
>>53807683
>>53807740
>>53807851
>>53807866
Only Lisps are truly general purpose because only Lisps have macros. If your language doesn't have macros, it's not programming at all, just code monkeying.
>>53808178
KILL YOURSELF FUCKING RETARDED SHITTER
>>53808180
>it's still fucking slow even with these things
It's not though. Even structs alone make a huge performance difference. And they are not difficult to use by any means.
>use C++ if you want performance.
C++ is more difficult to work with and less productive compared to C#.
>>53808208
>only Lisps have macros
nice bait
>>53808178
it intercepts a subset of your inevitable mistakes earlier in the testing process, depending on a compiler - with a sane error message that'll help you fix them.
>>53808221
yeah you're gonna do SIMD as if it's easier to work with and more productive compared to C++ and as if it even makes your C#shit as fast LMFAO KILL YOURSELF IDIOT
>>53808231

Well maybe C# isn't unreliable but Windows Server is. Basically the entire server stack at our company crashed because of Windows update at work and the company lost some clients because of it. I guess you could say Linux is also unreliable in some other areas but meh.
>>53808258

>>53808199
No evidence to support that. Many CS courses start out with languages like Python and they don't produce handicapped graduates. If there is any difference, it is insignificant.
These are the ramblings of a bunch of pedantic NEETs.

The compiler knows what type these are. Why do you have to specify it over and over again?
>>53808636
based on ocaml
>>53808636
You're not specifying the type, your choosing which module to use a function from. He could ask use Seq. in most of those instances, but that would do something different.
>>53808624
Why would it? (No, it does not)
>>53808636
Those are modules, not types.

I'm currently fixing minor bugs and refactoring some code. Next up is adding torrent support.

I recall doing that before and it would return an empty list if you have [1 .. 1]. Maybe i'm mistaken.

MLs don't have type classes. Hopefully modular implicits will come soon to OCaml so we can leave all these out
>>53808403
>Windows server updates automatically
You can pick and choose exactly which patches are applied, when they apply, and you can also test these patches on non-production systems first.
If your shit crashed due to Windows patching, the most likely culprit is the applications that the server is being used for, not the interaction with the OS itself.
>>53808922
In F# at least Seq.map and List.map will do different things. So doubt F# will be dropping this stuff soon.
>>53809026
The way that modular implicits work would not stop that from being a possibility, so it's possible that F# could adopt that system, but there are two things currently stopping that:
1) Some functions are overloaded in weird ways that aren't available to user-defined functions (like +, -, *, /)
2) F# doesn't have an ML module system still, and you can't do modular implicits without module types/signatures
For F#, I think Haskell-style typeclasses would actually be a more likely solution in the long-run
>>53809089
A lot of the stuff F# doesn't have is done to make it work better with .NET and C# code based, and be familiar to C# programmers. I wouldn't expect them to make any breaking changes like changing the module system going forward.

Anons, I'm new to programming but really good at math. Basically, autism personified, on meds for ADHD, some other crap. Point being, I have 30 days to get a new job or end up in the homeless shelter.
A friend of mine recommended I hire an Indian to make some android apps for me, and sell the apps on the Android market.
Realistically speaking, could I dish out lets say 10 shitty apps like a season count down, a clock, a music player, etc. within 30 days, and learn all the basics of Java programming to do this, within 30 days as well? 30 days guys. I downloaded the gentoomen library but some of the Java books are outdated and need IDE's like galileo, there are also dependency issues with the android downloads and java SDK, basically its very hard to follow or get the older versions working like the book wants me to.
So any help? Point in the right direction? Steam friend sent me a PDF of Java A Beginners Guide, 6th edition. Just start there?
>>53809146
good luck

Holy shit Thank you so much you pretty much saved me from leaving 4chan for a few days until it died down.

Hey guys I am really good at programming logic but I suck at math. I understand what I need to put together but I can't figure out the math to do it.
What it do?
>>53809214
There is plenty of software/hardware discussion of Google, Apple, Microsoft, and Linux, or as I've taken to calling it, Windows+Linux.
Why are you asking this in /dpt/ of all places?
>>53809146
You should spend these 30 days saving/packing stuff, learning about how to apply for whatever monetary help your government provides, visiting homeless shelters to see what you're gonna be dealing with - when to get there/what to have on you - stuff like that; looking for unskilled jobs, places with the cheapest rent, roommates. Learning a skill in a very competitive market + getting a job in 30 days is impossible
>>53809146
>could I dish out lets say 10 shitty apps
No. You might be able to put one app together with heavy copy paste form Stackoverflow but it's going to take you at least a couple of months to understand what you're doing at all.
