Replace C and Haskell with Lisp and it's accurate.

>>59222421
Lisp-1 or Lisp-2?

>>59222421
"C and Haskell" doesn't occur, so it'd be exactly the same

Rewrite it in literally anything else.

Great dragon choice, though.

col is a int
but strlen is size_t

what should the argument be: %d or %zu?

void pprint(char *err)
{
      printf("vir %d, tur %zu: %s: %s\n",line,(col-strlen(text)),err,text);
}

Why? Python is the best tool for trivial programs.

>>59222605
C++ move semantics force you to use null object if you want RAII. No thanks.

>>59222621
Yeah but there are some very bad things, like the way templates don't allow for good auto completion or no way to do interfaces without abstract classes/vtable.

>>59222621
it is, but 90% of /dpt/ always seems to disagree

>>59222656
yeah that's stupid, but still it's better than having no move semantics at all.

>>59222661
It's not a silver bullet, true.

C++ when necessary.
C# when C++ isn't necessary.

There. Your life is easy and you have access to mega high level and comfy sugar plus low-enough level and performance when needed.

Does anyone here have experience with grammars in compilers?

if the grammar doesn't have errors shift/reduce or conflicts, does it mean its correct?

>>59222699
It's not all about zero overhead. Try doing low-level hardware interfacing. Without move semantics, it's easy to make accidental copies, and end up with multiple objects trying to control the same hardware resource. It never ends well.

>>59223034
What do you mean "correct"? If it doesn't have shift/reduce conflicts it means it can be parser without backtracking, but that doesn't prove it corresponds to the idea you have of your syntax. This is another issue, so I'd say no.

I NEVER CALLED THE FUNCTION!!!

>>59223034
>grammars in compilers?
i am writing a compiler rn, i have 0 experience with it, 0 real knowledge
currently working on a bug, but my grammar looks like this and its preliminary, i will figure out a real syntax of a language later, so now my "language" looks like python lists

function_name = "factorial"
function_args = ["n"]
init_function(["if", ["==", "n", "1"], "n", ["*", "n", ["factorial", ["-", "n", "1"]]]])

So yesterday I enrolled in a programming program that lasts a year so now they sent me an "interview" online.

One of the questions is what would I rather learn

-WebUi and it specifies it's web design working with HTML5 CSS3 and web programming with JavaScript and JQuery

-.Net and it specifies it's about C# .NET , databases, web services and basic web programming


I chose .NET because I thought it would be the best but I figured that I should ask here for opinions before sending it.

>>59224122
You can do alot with c# it's very pleasant tho i dont quite understand why itgot rolled into the webdev meme

>>59224122

C# is like java without a lot of the succ, and the skills in one translate pretty much near 1:1 to the other with very little adapting time.
Jquery on the other hand is a framework so its not as useful to learn "in-depth" since frameworks come and go all the time.
html/css is simple af so you could learn it in less than a month.

#include <stdio.h>

int * sortArray(int *p, long l) {
    int tmp;
    for(int i = 1; i < l; i++) {
        tmp = *(p+i);
        for(int j = i-1; j < l; j++) {
            if(*(p+j) > *(p+i)) {
                *(p+i) = *(p+j);
                *(p+j) = tmp;
                break;
            }
        }
    }
}

int main(void) {
    int arr[5] = {3,1,2,4,5};
    int *p = &arr[0];
    sortArray(p, sizeof(arr)/4);
    for (int i = 0; i < 5; ++i)
    {
        printf("%d\n", arr[i]);
    }
    return 0;
}

all this code to sort some array
c a shit lmao

problem:

struct rs232_stream : public std::iostream
{
    rs232_stream(rs232_config c) 
        : std::iostream(streambuf.get())
        , streambuf(std::make_unique<detail::rs232_streambuf>(c)) { }

private:
    std::unique_ptr<detail::rs232_streambuf> streambuf;
};

The std::iostream constructor needs a pointer to a streambuf, which is not yet initialized at that point. wat do?

>>59224275
C standard has qsort you dump nigger.

>>59224275
You're an idiot, and your code is shit.

#include <stdio.h>
#include <stdlib.h>

int cmp(const void *arg1, const void *arg2)
{
    const int *a = arg1, *b = arg2;

    if (*a < *b)
        return -1;
    else if (*a > *b)
        return 1;
    return 0;
}

int main()
{
    int arr[5] = { 3, 1, 2, 4, 5 };

    qsort(arr, 5, sizeof arr[0], cmp);

    for (int i = 0; i < 5; ++i)
        printf("%d\n", arr[i]);
}

>>59224160
>>59224198
So as I thought .NET is my best choice

thanks

Can someone explain why the below doesn't work? I'm going through SICP. This exercise wants you to make a function that counts the pairs of a structure.

(define (count-pairs x)

(define (count-pair-wrap x traversed-pairs)
(if (or (not (pair? x)) (memq x traversed-pairs))
0
(begin (set! traversed-pairs (cons x traversed-pairs))
(+ (count-pair-wrap (car x) traversed-pairs)
(count-pair-wrap (cdr x) traversed-pairs)
1))))

(count-pair-wrap x (list)))

The correct solution is shown below. What could be going wrong?

(define (count-pairs x)
(let ((encountered '()))
(define (helper x)
(if (or (not (pair? x)) (memq x encountered))
0
(begin
(set! encountered (cons x encountered))
(+ (helper (car x))
(helper (cdr x))
1))))
(helper x)))

I'm new to this stuff and I'm stuck on this problem
I have to make a program in C that lets the user enter a phrase, then will censor a certain word, but if it appears in the middle of a word the program shouldn't censor it. We're only supposed to use basic arrays, if/else statements and while loops. Sorta get how to do it but the program still censors the word if it shows up in the middle of another.

Change the word you're searching for to SPACE WORD SPACE.

>>59225491

You're generally always well advised separating (A) thinking logically (independent of C technicalities) about the steps your program must take, ie. the algo and (B) how you'll implement it in C.

The algo: You're going to have to write a function that separate the user-specified sentence into an array of individual words (first split by space, then when that works split by all applicable separators such as comma, semicolon, punctuation marks etc), then you can simply iterate through your "words" and replace all occurrences of the forbidden word with the censorship, then reconstruct the user sentence from that so-updated array.

The C implementation: this is yours to work out to earn your grade :P

I just whipped this up and am looking for suggestions for GUI design. What should I add? What kind of input errors should I be catching?

Does your friend live in an ex-USSR country?

>>59222230
Let's say I want to write a Haskell program that accepts a time string like "23:42" and converts it to an ascii representation of a digital watch display. In C I would implement this by having an array of 3 strings that represent all segments of the display and a bitmask. I could do this in Haskell as well, but it seems like there has to be a better way. Can anybody give me a suggestion? I just started messing around with Haskell 3 days ago and have no experience with functional languages.

>>59226676
close enough

>>59226626
Delphi is just Pascal, a slightly more verbose Basic. Back ~20y ago, instead of Python or Ruby the "beginner-friendly, just start coding" languages for most folks were Basic and Pascal. They probably never updated their curriculum. And probably have some "mech-eng" libs or such ready for Delphi already

>>59226679
I don't think it would be too different, what sort of display are you looking for?

>>59226698
Pascal is not related to Basic. It's an improved ALGOL.

>>59226679
at some point you would probably want to map a function which converts any number to the appropriate ascii representation over a list of numbers

>>59226698
I'd also like to believe there's a sound reason behind it (I doubt it's the "libraries"), like some healthy engineering conservatism (not everything should change as fast as in CS) but teaching delphi to freshmen in 2017 is a bit of a stretch.

>>59226736
>I don't think it would be too different
Using functions with names like "complement" instead of '~' will make the code look hideous.
Something like this:

  _  _      _
  _| _|.|_| _|
 |_  _|.  ||_

>>59226772
That's the goal, the problem is I am not sure how to define those representations neatly.

>>59226659
Maybe state what the fuck you're calculating

>>59226838
the area of a polygon given the number of sides and length of sides.

I am mainly seeking GUI improvement recommendations, since the math is already on point.

>>59226803
>Using functions with names like "complement" instead of '~' will make the code look hideous.
You can make your own infix functions.

>>59226803
If you use -XPostfixOperators (in a source file, {-# LANGUAGE PostfixOperators #-} at the top) then you're allowed to create single argument operators
(~.) = complement
(3 ~.)

I would use a 10 element list of representations, whether or not you go with bits for each individual one is up to you, but you wouldn't be using complement.

>>59226873
>>59226897
> {-# LANGUAGE PostfixOperators #-}
Did not know about that, thanks.

>I would use a 10 element list of representations
I'm not sure I understand, you mean you would have 10 String arrays representing each individual digit?

>>59226958
I mean I would have a list of 10 elements, where each element is the representation
The representation doesn't have to mean the actual string (in fact that's more awkward because you'll have to break it apart to concatenate it)
If you think of your example, you have 7 toggle-able lines.
You could store that in a Word8 using bits.
So it could simply be

[Word8]
-- nb there's another extension called BinaryLiterals in GHC 7.10 and up
e.g. [0b01011010, 0b01011101, ...]

Then when you come to draw it, you could break that up into lines - for the first output line, you only care about the top bar. For the second, you care about the top left, middle and top right bars
etc

>>59226766
Yeah sure, true, historically speaking. In practice in the big picture they felt quite near-on identical to me in terms of expressiveness and power and flow of coding, starting out --- comparing them to asm, C, lisp back then.

Use file I/O to read an image into memory and transcribe to a 2D array of RGB values. Images will be scans of handwritten notes. Determine where characters appear in the page similar to below:

I like to pet dogs
I don't like cats

becomes

1,4,2,3,4,-1,1,5,4,4

Here's the sad reality about the IT world.
Practicality > concepts

Whereas in any other field, concepts are usually more important than being practical. Thus, why universities focus on teaching concepts and not being "hands on".

If you can't program, but you understand all of this bullshit CS stuff then you're fucked out of any job.

On the other hand, if you can program but are rusty with concept. but you know enough to copy and paste from stack overflow, you will be fucking rich.

Why not both?

Because universities teach either concepts or practicality depending on where you go.

Conceptualizing is harder than practicality, you can tell any buffoon how to do something, but you have to teach them why something does what it does.

To put it simply: Should you know this? Yes, if you want to get a good grade and make the most out of your education by learning concepts. No, if you just want to be another code monkey, but a rich one. (focus on writing programs instead)

>>59227591
That seems like a big jump from simple looping and basic data structures. SOMETHING SMELLS FISHY

>>59227662
I'm not sure I've seen a university teach practical skills. At least not where it's accidental, like when they give you an open ended assignment and the 'figuring out' process leads you down the more practical side of things. I wouldn't give the university credit for teaching what's being learned in that situation though.

Clearly the c++ one is less verbose, but it ties you down to noun->verb pattern which is not always applicable to datatypes. It also hides some of the memory layout and pointer indirection, and doesn't allow you to pass the structure by value. For the most part though, it is syntax sugar, which is not very impactful to programming. There are many more important pros/cons of C vs C++

>>59228330
No, because I'm not an idiot and recognize usefulness where it exists.

>>59228078
B but make it a class

A in a namespace if you only have one struct instance and don't need to pass a pointer

>>59228349

I very rarely use multiple inheritance or operator overloading.

I shouldn't even need to fucking try include or import any modules py2exe is a fucking piece of poo.

Can someone PLEASE tell me how to convert a .py script that includes all downloaded/standard modules and fucking turn it into an EXE, for god sake its 2017 how does PYTHON not have a standard lib to do this FOR US

I'm not too terribly familiar with using standalone python executables, but have you tried the cython compiler?

>>59228478
Or maybe python wasn't made for .exe's?

>NO NO MORE FUCKING MODULES AND PIP INSTALLS FUUUUUUUUUUCK WHAT THE FUCK IS THIS LANGUAGE IS IT FUCKING DUCT TAPED TOGETHER WITH LIBRARIES?????
Every language is duct taped together with libraries. Let us consider C or C++

>want to do database shit
Have to install libsqlite3 or some sql connector

>want to do HTTP shit
Have to install libcurl

>want to do graphics shit
Have to install libsdl2 or a similar library

Oh what do you know, Python isn't so alone. No language has everything you need in its standard library. Java doesn't come with CSV parsing functionality out of the box, and Ruby doesn't come with a GUI toolkit out of the box. Nothing comes with everything you need. You no longer can use this as a complaint about your language. Use a fucking package manager and eat shit.

>WHAT DO YOU MEAN??? EVERY FUCKING PROGRAM (As long as its running on an intel cpu) WILL BE EVENTUALLY CONVERTED INTO ASM INSTRUCTIONS HOW THE FUCK CAN PYTHON NOT BE MADE FOR .EXE WHEN THEY RUN?????????????????????

Python is a dynamic language that intrinsically requires a runtime environment capable of understanding Python code. Aside from the fact that the language is duck typed, it has eval(). When you wrap a Python program in an .exe, all you are doing is embedding the Python interpreter and all of the Python code into a standalone program that loads the Python code (or compiled Python bytecode as it may be) into memory and executes it in the Python environment.

On that note, you might as well just ship a C program that loads your Python program from source and executes it.

>EVERY FUCKING PROGRAM (As long as its running on an intel cpu) WILL BE EVENTUALLY CONVERTED INTO ASM INSTRUCTIONS
No, this is not correct, where did you learn this?

>>59228642
Does it save spaces and newlines?

i just thought of something fun, using my old laptop to monitor whether my neighbors (i have 3 apartments near me) are around by measuring their wifi activity and plotting their activity over time. is there something like this around?
