Which do you suppose is faster? ("seen" is initial array structure before it becomes populated):

seen = [""]
j = "".join(sorted(seen[index] + COINS[k]))

seen = [("",)*8]
j = seen[index][:k] + (seen[index][k] + COINS[k],) + seen[index][k+1:]

seen = [()]
j = tuple(sorted(seen[index] + (COINS[k],)))

Compiler for Pseudo Pascal targetting LLVM. I'm pretty much done with front-end stuff, I had the type checker done and then realized the syntax was fucked. The language itself looks like that:

program
var x : integer;
function times (p,q : integer) : integer;
begin
   times := p * q
end;

function fact (n : integer) : integer;
var r : integer ;
begin
   r := 1 ;
   while n > 0 do
   begin
      r := times(r,n);
      n := n-1
   end ;
   fact := r
end;

begin
   x := readln ();
   writeln (fact (x))
end.

The C++ interface allows you to build IR from your source, you can see the builder here http://llvm.org/docs/doxygen/html/classllvm_1_1IRBuilder.html. It's still some work (especially on the semantic side) but the real strength comes from the fact it has the architectural optimizations (usual middle end stuff) done for you.

Also I plan to try to use raw LLD to link executables but this might be borderline insanity. There's always the back-up plan of using a host C compiler to link .o files anyways.

In C/C++, how would one go about parsing a text file to get settings for a game?

Here is an example, (parts of) the settings file from Duke Nukem 3D

What is a ``Powerful" programming language?

>>60652204
If your asking out of curiousity. well it's pretty involved in C, less so in C++.

If you're asking because you wanna parse config files - shit nigga just use Lua (assuming you'll be using it for more than just config files.

>>60652204
this:
>>60652235

anyways, read file line by line and store the lines that dont begin with ';'

store each value found after a '=' symbol somewhere in memory and your done

>>60651941

I've been getting interested in "coding challenges" lately. I feel like they can be a fun way to practice some more advanced stuff and functional programming. How does one into them?

>>60652235
I did not understand any of that. What I am asking, is how can I read a .txt file in C, but have the program know to skip semicolons, know what section it is in based on the [] it just passed, and then set whatever is on the left of the = to whatever is on the right of the =.

>>60652289
I use lua but I didn't really want to use it for config as well

>>60652311
i'll look into that

>>60652315

>>60652309
>lisp is turing complete i garuantee
so is basically anything thats not html, json, sql, xml, css, etc

>>60652071
Basically compiler writers only have to make the compiler output LLVM IR which can then be compiled to machine code on any LLVM supporting system. Thus people don't have to rely on JVM to create relatively cross-platform languages, they can instead create cross-platform languages which compile to native code.

>>60652315
if you have a decent search term history with google with alot of java and python related queries, then google "python pass by reference" and you will get an invitation to google foobar

>>60652204
You search for tokens before the "=" in the string which will pertain to some variable in your program, and you assign the value to the right of the "=" to the variable. You can roll your own string tokenisation function which lets you split a string based on a character and use the "=" as the character to split on, thus giving you both sides. Everything else is ignored.

>>60652114
>two appears to be the most efficient method
Those timings don't do it justice, as the elements don't grow. It completely eliminates the overhead of sorting. But of course the naive thing to do is rely on builtin sorting methods where sorting is applicable - I see this time and time again in algorithms.

>>60652316
>I use lua but I didn't really want to use it for config as well

Why not, i mean it's far easier than reinventing the wheel. It's already loaded, it's already part of your code. and it's stupid easy to use for config files - so why not?

>>60652437
tracking cookies dont matter. They track by IP. my browser clears everything every time it closes and I dont use an account with google. After enough java and python queries they begin offering it to anyone at the IP address.

>>60652424
who cares?

anon posted 3 sets of 2 lines of code and asked which set of 2 was quickest and theres the answer, set 2.

>>60652448
I have a dynamic IP, all people do on my ISP. That would mean random people get "offered" whatever this crap is. It would also mean random devices on the LAN would be given this "offer" depending when google deems a search relevant. So you're either bullshitting, or you're browsing habits are not as anonymous as you think. I'm guessing it's the latter, given that you willingly use google, and probably are signed into their various services, which keep track of browsing habits on their side even if you clear your browser.

>Functions inside header files

>>60652633
Start by defining how it will be anime-like.

>>60652559
>>60652544
do you not know what the purpose of header files are

>>60652647
>>60652697
w w-what

Been reading the Rust book, it seems like a decent language so far

Has anyone ever stopped to realize how stupid it is that people are forced to forward declare all extern functions twice?

>>60652647
Like I said, I'm only two weeks into C, please educate me! What should header files be used for? And should every single function I used be defined in the main .c file?

>>60652539

No, but it is a minimum requirement.

>>60652633
First decide what major features you want from it and which paradigm(s) it will allow you to program in. Then think about the core semantic actions, define a grammar that allows you to perform these actions the most concisely/clearly possible, implement the front-end (parser, type checker, error handler). You can then decide whether you want it to be interpreted and use a host language to execute your syntax tree (in which case your implementation is an interpreter) or rewrite it in a lower/different language (then it's a compiler). Popular languages to compiler to are assembly, C or LLVM IR. Finally, write useful software/ecosystem for your language and shill it on 4chan.

>>60652733
For each "module" (set of functions, structures, etc) define a .h and a .c file with the same basename. Provide function prototypes in the .h file, and function definitions in the .c file. Include the .h file in both the corresponding .c file and in main.c.

>>60652733
Header files are usually just used to share function declarations between files. Actual implementations of functions go in .c files.
Usually it's done like

// file1.h
int myfn(int arg);

// file1.c
int myfn(int arg)
{
    return arg + 1;
}

// file2.c
#include "file1.h"
int main()
{
    int a = myfn(1);
}

>>60652733

Header files (.h): typedefs, macros, and function signatures.
Source files (.c): actual function definitions.

I am trying to model the following:

Create a static int method for partialsubsequences that are positive and take an int array.
Have three variables.

count =0;
first =0;
second =0;

While the array hasn't reached the end of index, do the following:
1.while [count] array is>0:
     first++;
     In.readnext Index();
2.while [count] array is <=0:
     In.readnext Index();
3.while [count] array is >0:
     second++;
     In.readNext Index();


if first >second:
    second=0;
    do 3rd step;
else:
    first = second;
    do 3rd step

how do I do this,make more methods?

>>60652753
>core semantic actions

what is this

>>60652559
>Misusing header files
>cmake over regular make or gprbuild
>moderately decent error handling
5/10

>>60652733
C (and many other language) compiles each source file into an object file before linking it as an executable. In these object files go the actual data that come from your source file such as instructions, global variables, read only data etc. Anything that will directly be in that object file should be in source files. Anything that is required by the developer/compiler/contributor should go in the header instead. This goes for function declarations (and not definitions!) since the compiler needs to know how to call functions from other translation units (the translation unit is the C abstraction of the object file).

>>60652786
You're too stupid to make a programming language, much less interpret it in software.

>>60652733
>>60652708
you declare functions in the header, that is you only put the prototype

// foo.h
int bar(int x);

in the .c file you put the definition (some people call it the implementation)

// foo.c
int bar(int x){
/* do shit */
}

generally in the header you want to only provide function definitions, structs, and macros that clients of the header (other parts of the code) will use.

Read up on how to compile multiple .c files and link them, though using cmake it does that stuff for you. But you should learn how to do it without cmake as well or you'll be clueless as to how compilation works.

>>60652788
>>moderately decent error handling

define good error handling

>>60652765
How does file2.c know what the function in file1.h actually does without either including file1.c

>>60652786
The idea behind your abstract syntax.
What action is each node supposed to correspond to.

>>60652802
can you explain what a "semantic action" even is

>>60652815
can you give a practical concrete example

>>60652813
It doesn't NEED to know what the function does. It just needs to know how to interface with it.

>>60652823
>>60652815
Your program can be seen as a tree, what is each node supposed to do?

>>60652813
it doesn't need to know that. they are compiled seperately then the linker will make the function call "link" to the object code from the other file.

Are there any software engineer positions that don't use Java?
And how much Java should someone know before applying? I don't know what an employer would expect me to be able to do as an entry level/junior position.
I'm graduating as a computer engineer but there are a lot less jobs so I'm just trying to get prepared in case.

>>60652983
I mean print_usage terminates your program, and you can see why this is a problem since you forgot and call exit again on line 58.

>>60651640
why the FUCK won't this compile?

int main(void)

int user_input;
printf("Ayy nigga, enter a number:");
scanf("%i",&user_input);
printf("%i is the ascii code for %c"user_input,user_input);
return 0;
}

   }return first;
}

does this make sense to you?
I have a lingering problem with the continue and where to place it, but the gist is, if the "first" is bigger than the "second", skip the 1st if body and check the other one until the "second" has become bigger than than the "first" and replaces it.
repeat it until I have the longest indices of consecutive positive numbers in an array.

RAII, faggot
And a GC isn't inherently bad. dlang-chan, as she stands now, handles everything pretty well. For code segments that need efficient, you can disable the GC for them. You'll lose some language features however. But that's what dlang-chan's parents are trying to fix: making the GC completely optional in the standard library, Phobos.

Why are you reading input in this function?

I literally just moved all the .h files to .c files and created a header with some declerations, I made no actual changes

It should read the next index of the array that has been created after I opened a textfile with various numbers with different digits and negative and positive numbers.

>>60653908
>RAII, faggot
yo okay YO but what if

what if in acquired resources you stored information on how they were acquired

and then you had the GC automatically do whatever the opposite of that is when it gets to them

Hmm, but sometimes "the opposite" might not be a process that can be generated automatically, depending on what you're trying to do...

Golly gosh, if only there were a way to configure the GC so it takes care of non-memory resources automatically, but using a process you supply manually!

>>60654057
dumb frogposter

>>60654052
How to go about splitting off things into functions is very subjective and takes a lot of experience/taste to do well.
Having enormous functions which do a million things can be very hard to read and reason about, but splitting everything into tiny functions does basically the same thing.
Just try do what you think is appropriate.

Gonna need to go into some specifics there.

>Golly gosh, if only there were a way to configure the GC so it takes care of non-memory resources automatically, but using a process you supply manually!
Yes, but can it be done deterministically? The benefit to RAII is that this happens not only automatically, but immediately upon the resource in question going out of scope.

there are patterns, but I do not know how to make it. my brain has reached the kind of limit where I can only do the barebones.

Is that java? You should not program in java.

Is there any easy way to get characters with umlauts work system independent in C?

I'm writing a graphical program in C and I have this bitmap font thing where you get an area of the bitmap via character index. So if you want to get the rectangle on the bitmap for character 'a', you simply pass in 'a' as a parameter:

int rect[4];
get_char_rect(rect, 'a');

But that doesn't work with characters that have umlauts, for example 'ä' - you have to give the character code directly (like 0228 for 'ä'), and those are difficult to remember. Do I need to just make macros for those letters or what?

Pajeet, you have failed me for the last time

>>60656585
Man wait wait wait wait wait, char are bytes not characters, your solution works only on latin-1 locales, and congratulations! You are delving in the fantastic realm of character encodings! So really take some time to read up on utf-8, and try to understand what's really happening, please, we've had enough unicode-related bugs in this planet already.

>>60656806
Second this, also http://utf8everywhere.org/ .

>>60656806
Wait no, your code doesn't have the bug I thought.

L'ä' == 228

, that's an answer for you. Should work with all unicode characters regardless of encoding.

I have a challenge for you, DPT!

I want to make custom CSS for 4chan. Every line that starts with ^ should be orange in color.

var lines =document.getElementById('postMessage').innerHTML.split('\n');
for(var i = 0;i < lines.length;i++){
if(lines[i].startsWith("!")) lines[i].fontcolor("orange"); 
}

I'm sorry, I don't know how to program, I'd be willing to fill in the channels myself though, I just think it'd be something nice to spread around for people that might wanna use it.

Since the internet has memed me into thinking PHP is terrible, what should I use instead?

>>60657617
Use node with TypeScript.

>>60657617
have you tried php-7?
If php is not for you then you should totally use node, it's fast and it's webscale and it's awesome and girls use it too.

>>60654775
WPF is objectively the best desktop GUI library, if you're targeting Windows systems.

Don't let XAML scare you. There's a curve to using it properly with MVVM, but once you figure it out, you can shit shit done quick and in a very maintainable way, plus it'll be easy to decouple your data/logic and use it with Xamarin for a mobile/iOS/Android/Linux application.

Why would I want to use a C++11 instead of a function pointer?

>>60658125

*C++11 lambda

>>60658125
Your question doesn't make sense, but you shouldn't use C++ under any circumstances.

>>60658125
You should use striped knee high socks instead of both.

>>60658136
C++11 lambda can be inlined while function pointer can't.
C++11 lambda can capture values from the environment.
C++11 lambda can always be cast to a function pointer.

>>60658164

>C++11 lambda can capture values from the environment.
Can't you just make a struct with the captured variables, and then pass that with the function call? It seems like it achieves the same effect as a closure, albeit messily.
>C++11 lambda can always be cast to a function pointer.
So how does that work with captured variables?

hey /g/

i just suddenly started getting linker errors for curl++, even though i havent made any changes to the makefile

what the hell is going on. it took me forever to get all the dependencies and linking options right and now its all gone to shit

>>60658221
One post too soon, but I'll let it slide today.

>>60658186
This is basically that the compiler does, C++11 lambda is just sugar for

class _muh_lambda_no_123 {
public:
    _muh_lambda_no_123(int a, bool b) : _captured_a(a), _captured_b(b) {}
    operator() (/*lambda args here*/) { /*lambda body here with a and b replaced with _captured_a and _captured_b*/ }
private:
   int _captured_a;
   bool _captured_b;
   /* etc. */
}; 
_muh_lambda_no_123(a, b)

It was about 100 different undefined references to various curl++ symbols

I have no idea why, but rewriting the entire makefile, deleting the executable, object files, etc, fixed it.

Does anyone use amphetamines (adderall) specifically for programming purposes?

I'm prescribed it and honestly hate the stuff after a long time of taking it, but whenever I had an assignment for a CS class I lost myself in the code and that's the only time I've felt completely in the zone with it. Any tipz for using drugs in your development sessionS??
