i've done like..

to which i tried to strcpy, assign directly (newnode->blah = response;)
i got one kinda working but every time i printed out asll my struct elements they were all the last one i typed
so if i had like
first name
last name
age
website
and i put www.gewgz.com, first, last, age and website would be gewgz.

If you're using the same pointer it will always point to the same line and your next getline call will overwrite its contents. Make sure you set **response to NULL again and assign whatever that points to into your struct.

No nap. This was just aquestion I remembered i waned to ask and notice d i had dpt open up in my list thing. i'll sleep tomorrow.
even when i used different pointer-- nevermind i think i see my fuckup.
I have this code
while(cur != NULL) {
if(strcmp(word, cur->word) == 0) {
int i;
for(i = 0; i < MAXFILES; i++) {
if(cur->freq[i] > 0) {
FreqRecord *record;
if((record = malloc(sizeof(FreqRecord))) == NULL) {
perror("record");
exit(1);
}
record->freq = cur->freq[i];
strcpy(record->filename, filenames[i]);
records[reqCounter] = *record;
reqCounter++;
}
}
FreqRecord *emptyRecord ;
if((emptyRecord = malloc(sizeof(FreqRecord))) == NULL) {
perror("record");
exit(1);
}
emptyRecord->freq = 0;
strcpy(emptyRecord->filename, "");
records[reqCounter] = *emptyRecord;
break;
}
cur = cur->next;
}
for starters strcmp is returning 0 when the comparison is "write" and "a'cock'bil", which are not equal...
second it seems like when it gets to the empty record it jumps back and does more for loop iterations, i'm not sure if ddd is just fucking up or my code is wrong. my braces are closed right, so I don't know.

>browsing 4chan is programming because you press buttons to execute some javascript in the background to tell the computer what to do
You are misinterpreting, perhaps on purpose.
Writing programs which tell a computer what to do is programming. If you told the computer to press certain buttons on 4chan by writing a program, that would be programming.
If you're writing a program, essentially a set of instructions, then you are programming. There is nothing more to it than that.

The level of skill required depends on what's being written, and web development, being so diverse with many applications, can be said to require high or low levels of skill.
The idea that programming must also involve theory from computer science hasn't been proven.

No, I'm not going to bother because we're in /dpt/ and not /wdg/ which is a general dedicated to web development yet you bring web development into /dpt/ so you're simply shitposting at the best.

My point was that nobody has shown that programming must necessarily "involve" theory from computer science.
>Yes, that also happens when nubs try to sysprog. Your point?
My point is that the idea of certain programming languages allowing one to "brute force" code is silly and fallacious. Only people who literally don't know how to program copy and paste code from other sources without knowing at least what it does.
What you describe as the "brute force" in web development in general also really just applies to noobs in web development.
>>53715052
>I'd have to see the PHP environment configuration to figure out what the function does.
The same could be said about other languages such as C which leave certain things implementation defined. In fact, it's worse in C because you can have UB.
>>53715112
Prefer 'effect'. Side effects should be reserved for fuck-ups.
>>53715127

}
err = avformat_find_stream_info(ctx,NULL);
if (err < 0) {
return -1;
}
return ctx->duration;
}
This works just fine. But when I try to use an array as input.
AVFormatContext * create_context(unsigned char *opaque,size_t len)
{
unsigned char *buffer = (unsigned char*)av_malloc(BUFFER_SIZE+FF_INPUT_BUFFER_PADDING_SIZE);
struct buffer_data bd = {0};
bd.ptr = opaque;
bd.size = len;
AVIOContext *ioCtx = avio_alloc_context(buffer,BUFFER_SIZE,0,&bd,&read_packet,NULL,NULL);
AVFormatContext * ctx = avformat_alloc_context();
//Set up context to read from memory
ctx->pb = ioCtx;
//open takes a fake filename when the context pb field is set up
int err = avformat_open_input(&ctx, "dummyFileName", NULL, NULL);
if (err < 0) {
return NULL;
}
err = avformat_find_stream_info(ctx,NULL);
if (err < 0) {
return NULL;
}
return ctx;
}
AVFormatContext doesn't have duration set, well set to the error value that is. The rest of the fields seem just fine and I can work on it.

If I had input for a game that is similar to Unity or Unreal in that certain inputs and axis have names that can be grabbed from pretty much anywhere.
Should I have a global Input singleton? How would I "register" different methods of input such as a controller thumbstick + mouse for a "Look Axis" input and would it be organized like a Input::Instance()->GetAxis("Look") kind of thing. Would the Input be updating variables every frame or would it be retrieving the state of the named buttons on the spot.
Something like "Jump" could be either "A" on a controller or "Spacebar" on a keyboard but How would I register both of these events and have it function properly for something like that.

For example, consider the function signatureid :: a -> a
Which means that id is a function that takes in a value of any type and returns a value of that same type. What could this function do? Excluding broken functions that loop forever and never produce a result, there is exactly one implementation that fits this type signature:id anyValue = anyValue
Which simply returns the original argument. This is really cool if you think about it. In PHP, a function with that signature (I use the term signature loosely because php is dynamically typed) could do anything. It might read data from /dev/random/ and coerce the result into the type and then return it. It might increment a pointer and return null. It could launch missiles at Cuba before returning null. The only way to exclude possibility is to read the function definition. This is what makes Haskell so great - you can tell a lot about a function just by glancing at a type signature.

The other day I had an interview and the guy was asking me lots of questions about the concept of Test Driven Development, Unit Tests and how to throw a nice unit test framework around webservice development.

>>53716219int id(int);
Only works for ints whereid :: a -> a
works for all types.int id(int);
could do arbitrary IOid :: a -> a
does no IO
> too lazy to read what the function does
have you ever worked on a large codebase? Just a few weeks ago an engineer at work modified a function that previously did no IO to make a call to an external service. Since that function is called probably 200 million times per day by our clients, we brought down the external service with a very effective DDOS. If we had written this in Haskell, the engineer would have said "huh, this function does no IO. maybe I shouldnt make an architectural change my making it do IO." In fact, his change wouldnt have even compiled. Making guarantees like that is very powerful.
>>53716292
they were trap questions, the answer was 'unit tests are completely unnecessary and only makes people good about themselves."
>>53716314
So, to be clear, the type signature of a function specifies whether the function will do any IO in Haskell?
Doesid :: a -> aconstitute a function by itself?
What is the difference between this and:function id($x) { return $x; }?
>>53716374
>So, to be clear, the type signature of a function specifies whether the function will do any IO in Haskell?
yes
>Does id :: a -> a constitute a function by itself?
No. It is a type signature only.function id($x) { return $x; }
has no guarantees about how much IO it will do. Yes, I can tell it currently does no IO by looking at it. But that could change in the future. A direct translation to haskell would look like:id :: a -> IO a
id anyValue = return anyValue
>haskell is so shit, doing IO is a hack and needs to be a function specifier for itself and has keywords for itself
gee, a function may do IO? stop the world!
>>53716433
Okay, thanks.
Seeing as id accepts any type, what would happen in the case that we have:id :: a -> IO aand I provide id with the argument "sometext"
id anyValue = return anyValue + 1
>>53716451
You dont need to stop the world to do IO in Haskell, you just need to add IO to the type of the return value. Its not a big deal or an epic meme. It just gives the programer and compiler more information to work with.
>>53716462
That wouldn't compile.
>>53716462
Would not compile. Error would say something to the effect of "cannot determine that a and 1 can be added because a can be any value and not all values can be added together."
>>53716462
wouldn't compile
>>53716503

>>53716577
Yes, what?
>>53716533
Why? The explicit type signature puts no restrictions on the value of a, so a could have type Car or any type that coudnt be added. That's why I sayid :: a -> a
has only one implementation - there's not much you can do to arbitrary values and no IO. If you wanted to your function to work on addable values, add a Num restriction:fun :: Num a => a - > a
which reads "for any type with + defined, take in a value and return a new value of the same type. Sample implementations could be:fun a = a + 2
fun a = a + 3
fun a = a * 5
fun a = a

Pure C ;_;. How does bash do it?
>>53717055
you can't
>>53716547
Is there a language that builds upon brainfuck and uses code snippets like yours as functions?
it'd seem a lot like writing shell scripts since you're streaming IO across programs
also it'd allow parallel execution of brainfuck code
>>53717061
Okey. Then how does BASH/Zsh do it?
>>53717055
Bash uses the readline library. Other shells use libedit I think? You can make your own with (n)curses or POSIX.
>>53717061
He can, if he checks for \t from stdin.
>>53717074
Your terminal uses a system specific library to get key inputs.
>>53717081
stdin is usually buffered on OSes. No key will be sent until user press enter
>>53717081
Thanks!
>>53717049
Claret is a wine, doofus
>>53717111
>stdin is usually buffered on OSes
This is why set(v)buf exists.
>>53717073
implementing a brainfuck interpreter is not that hard, you can easily make a library to support brainfuck in your code
>>53717142
here's the (You) you want for attention
>>53717073
>also it'd allow parallel execution of brainfuck code
I posted a brainfuck implementation that supported pthreads a few years ago.
>>53717148
are you sure this disables terminal's buffer? I am not on linux right now
>>53717205
No, it's not portable. You need to use POSIX functions there.
>>53716834
you did, here >>53716667 are you autistic?
>>53717351
Actually, I am. Pretty low to use that as an insult.
>>53717351
Not me. You claimed something about "arbitrary values" before that at >>53716647
>>53717363
woah man I had no idea sorry dude I didnt mean it as an insult. its endearing, you know?
I'm working in c++. I have a vector that stores structs which have a char as a member field and I have a class that has a set as a member and it stores pointers to the stuff inside the vector I mentioned.
I did a fucking double check. Inside the class constructor, I print out the addresses I stored in its member set and then after the whole construction is complete I iterate through the instance of the class and it prints back the addresses I constructed it with. When I dereference them inside the constructor they give the correct chars, but when I dereference those addresses again somewhere else, even though they are correct, the chars are fucking gone.
I'm losing my mind here. What can cause crap like that?
>>53717543
maybe pointers get invalidated when vector reallocs?
generally, you don't want references/pointers to items in vector
>>53717543
Sounds like the vector went out of scope. If that happened your pointers would be pointing to garbage.
Please suggest some good short intro to Linux GUI theory. I used to develop GUI apps for Windows for a while but I don't want to develop for a shitty proprietary botnet OS anymore.
>>53717543
use a deque
>>53717578
>>53717622
That's the first thing that occurred to me, but that's strange. the first thing I do is fill the vector in, and I don't touch it after that.
the code is more or lessreadIntoVector(vector);
readIntoClass(Class, vector);
PrintOutWhatEverIsIntheClass();
>>53717709
As someone who did this, there are no good docs, Glade is your friend, you are going to have to deal with GTK at some point.
I just pretend everything is GNOME and rig something together with as little actual interactiion with GTK as possible.
>>53717736
It's just what I don't want since I'd have no way to procure the address of the element I need.
>>53716048
SQL isnt a programming languages, its a query language.
Its even in the name you numnut
>>53717860
You can program with SQL.

>>53714483
what's so bad about Swift? i messed around with it a while back, and while the syntax wasn't optimal, the language itself had a pretty decent set of features
>>53715161
this is the term generally used with algebraic effects
>>53717744
You are using a copy of the vector instead of the actual vector. The copied vector goes out of scope as soon as the function call ends. Try passing by reference instead.
>>53717947
*using a copy of the vector instead of the actual vector when you pass it to a function.
>>53717918
That reminds me, I've been meaning to try out Silver, which is Swift for .NET.
>>53717947
>>53717964
I figured it out on my own, but thank you nonetheless.
>>53717981
>try out Silver
wat
>>53718020
It's Swift, but for .NET, so I don't need to be a MacFag to use it.
>>53718085
I hate to be such a shill, but can't help myself, so here it goes. Why not give F# a shot instead?
>>53718085
Just a normal fag.
Filtered.
There is no reason to use go when nim exists.
>>53718166
>nim
Trash
>>53718156
I'm a fag. Frankly I have nothing against F#, and no reasons not to use it, I just haven't gotten around to it yet.
I hate asking and you will all tell me to fuck off but I'm new to programming and I want to learn C or C++ to program my arduino for projects, Is it a bad start to learn a hard programming language? Am I digging into something that will be too hard for me and in the end will make me hate coding? if it's a yes which language should I go to in the first place? I just wanna do robotics
>>53718323
>Is it a bad start to learn a hard programming language?
No, this is a meme.
>>53718323
all programming languages are basically the same. C or C++ aren't inherently hard to learn, theyre just harder to learn
Would making a multiplayer websockets game be considered programming or should I fuck off to /wdg/?
>>53718188
>passing judgment on a language he's never used
typical behavior you'd expect from a Go """programmer"""
>>53718404
I don't use Go :^)
>>53718341
>>53718350
So which one is more benific? C++ or C? I know that C++ is object oriented and C don't.
>>53718444
C++ is a clusterfuck. Just learn C if you want to program your ardwooynoh
>>53718444
C++ is not really Object Oriented. C++ is clusterfuck oriented.
>>53718462
>>53718477
kek ok, I started to read this yesterday it<s quite easy to understand in the beginning yet my friend who program told me I<m in something that might turn me off
>>53718536
It was the reverse for me. C is what turned me into programming. I tried C++ and some shitty languages before but they didn't taught me anything.
>>53718536
Start with nasm, then progress to fasm and tasm. Learn some ARM too
>>53718580
>not starting with GAS and staying in GAS.
>>53718444
c++ is way more benefic.
you can't really use C for anything other than writing drivers, kernels, and embedded
>>53718599
Spotted the bullshitter.
Hi, can anyone solve this problem?filepath = '/path/to/directory/myfilepaths'
location = raw_input('Where is the file? ')
with open(filepath, 'r') as mf:
for line in mf:
nline = line.replace("\n", "")
# cline = glob.glob(nline + '*') #PROBLEM LINE
path_obj = os.path.join(location + str(nline))
obj_stats = os.stat(path_obj)
Inside /path/to/directory/myfilepaths(file)/current/0.e_head/10000000d.000000002__head
/current/0.13_head/10000008.000000001__head
..
The true filenames on the file system is/current/0.e_head/10000000d.000000002__head_918293
/current/0.13_head/10000008.000000001__head_9891283
So what I have in myfilepaths is a list of file paths, I know this may sound weird but what I need to do is iterate through a list of files in myfilepaths and then perform actions on these files. So what I am looking for is to use glob as * in linux, where I can match any files which start 100... whatever and then put * to match all files with unpredictable characters at the end.
When I delete the comment in the problen line and change to cline in path_obj. It says my input fromlocationwith [] at the end.
Can anyone help me please?
I'm trying to 'link against a library' in C++. ITS NOT FUCKING WORKING
I've watched over a billion fucking tutorials on youtube, I swear to god im gonna strangle a fucking puppy someone explain me how I do this fucking shit
http://www.oblita.com/interception.html. I'm trying to get the first example working
Running MinGW and CLion. Pretty much a beginner in C++.
I've downloaded the interception library (which included two folders x86 and x64, and the files interception.h, utils.c and utils.h).
Next I've done this in my CMakeLists.txt:
>set(SOURCE_FILES main.cpp utils.h utils.c interception.h)
Next I've copypasted the first example on the interception page, BUT instead of doing
>#include <interception.h>
I've done:
>#include "interception.h"
Because <> wasn't working at all
I've put all files and folders in the root directory of my project. I have also run the .exe command line thing that the website told me to do.
Someone please fucking kill me
>>53718674
I'm having literally the same problem for the last 12 hours now.
FUCK YOU ECLIPSE FUCK YOU
>>53718674
how how easy this would be without cmakeg++ -linterception main.cpp utils.c
>>53718674
lol, windows.

well to answer your questionset_target_link_libraries(interceptionTest interception)

>>53718580
>>53718593
wait what?
>>53718804
Nothing
>>53718768
he also needs FindInterception.cmake module in CMakeModules, because clion + windows lol

This shit is giving me fucking cancer, should I just use G++ and like Notepad++? I really like CLion because I'm a jetbrains cuck, but CMake is the worst fucking thing I've ever experienced
>>53718869
yes.
fun fact: shit autocomplete will make you a better programmer because you will have to read the documentation
btw you could also use visual studio it's very easy to link libraries there
>>53718869
oh, my mistake
it'starget_link_libraries
>>53718674
>>53718738
yet another example of why not to use an ide
>>53714324
A small toy project on JS and react that went out of hand and became a year project.
>>53718869
Use GCC and Kate/Nano/Emacs/Whatever on GNU/Linux.
>>53718738
This is wrong btw
the -linterception needs to go behind the source.g++ main.cpp utils.c -linterception
When the compiler scans the source it keeps unresolved links for later. a-lLibraryscans the library for any symbols that have not yet been resolved in the source files scanned so far.
>>53718914
Isn't that how it goes? From "I just want to test this out" to several K LOC.
>>53718890
>btw you could also use visual studio it's very easy to link libraries there
Other anon with the library problems here. Fuck this, you're right. Nobody should have to go through 12 hours of this bullshit. So long eclipse, hello VS
>>53718567
yup, initially tried C++ and i basically learned nothing of substance when i tried
>>53718967
but the god tier choice is emacs.
other than being infinitely customizable, the navigation keybinds are irreplaceable.
i can't use any other editor without rebinding everything to emacs keybinds
Tfw you btfo everybody who tried to bully you for programming in Notepad.
What's the point of programming when everything already exists as an API?

What is /g/ recommended text editor for a beginner programmer?
I am using notepad++ and sublime text 3, sublime text 3 is cool.
How do I make something good? Should I java?
>>53719257
Java will make anything good
>Learn C
>Write some sorting algorithms
>Get bored
What now?
>>53719327
Sort your sorting algorithm with a different sorting algorithm.
>>53719242
Sublime text on windows, Emacs on Linux
>>53719242
Notepad++ or sublime.
