Just use C# and the "dynamic" type.

>>57375158
I realize that. It's a bit of my frustration coming through.

I've been pushing for more design discussions and attempts to nail down our actual spec (because we've had to rewrite classes multiple times due to missing large edge cases causing bad behavior) but it's hard when your coworkers can't explain why they're doing something a certain way and are not willing to budge an inch.

We have a couple of perfectionists who believe that their way is the only way to salvation, so we end up rewriting code according to one person and then having to rewrite it entirely later because either they changed their mind or someone else didn't like it.

It's not. Emacs is more extensible. Kakoune has bette vimgolf scores.

Mousepad is pretty straightforward desu.

>>57375401
So use emacs for a bit and see how you do. My only experience with emacs was harrowing, I had no idea what the fuck I was doing. I'm sure I could soldier through and become useful in it.

>>57375401
>You don't even know what my issue is.
I don't need to, because vim is not "shit", it's actually a pretty damn good editor.
Chances are you're using it wrong.

>>57375416
>What's wrong with a minimal GUI text editor?
It's inefficient. Switching back to a non-modal editor would make me want to kill myself.

>>57375431
>My only experience with emacs was harrowing, I had no idea what the fuck I was doing. I'm sure I could soldier through and become useful in it.
Same here. But I'm so used to vim that switching will be painful for months.

>>57375435
>I don't need to, because vim is not "shit", it's actually a pretty damn good editor.
Vim uses a good editing paradigm but is terrible otherwise. Vimscript is terrible. Its C code is terrible too. Its maintainer is a lazy fuck. Vim is shit and I say that as someone who's been using it daily for more than 6 years.

>>57375526
>Vim uses a good editing paradigm but is terrible otherwise. Vimscript is terrible.
I completely disagree, I'll take vimscript over elisp)))) any day.

>Its C code is terrible too. Its maintainer is a lazy fuck
I'll give you that, though it looks like Neovim is lighting a bit of a fire under his ass.

>>57375526
>It's inefficient
I disagree. I'll never understand codemonkeys... I basically spend more time thinking with a sheet of paper than programming.

I'm converting a hex input given by the user and it outputs the value in decimal. It doesn't work and I don't know why.

 

unsigned long int hex2dec(const char *hex)
{
    int sum = 0; 
    int v= 0;
    int n=strlen(hex);                
    for (int i = 0; i<n; ++i)        
    {
        if(i==n-1)
        {
        return sum; 
        }        
        if((hex[i] >= '0' && hex[i] <= '9'))
        {
            v = hex[i] - 0;
        }    
        else
        {
            v = hex[i] - 'A' + 10;
        }
        sum += (v * pow(16, n-1-i));
    }
}

>I basically spend more time thinking with a sheet of paper than programming.
The faster you'll edit your files the more time you'll be able to spend with a sheet of paper. That's exactly why I need to be able to code as fast as I can.

>>57375603
If you don't need to think while programming then you're not doing anything useful.

>>57375568
You're returning the value before finishing parsing it for starters

I'm learning java at the moment.

How do I store a bunch of user inputted numbers in an array?
Currently I'm doing this:

public static double CalcAverage()   //create new method named CalcAverage
    {
        double dGradeCounter = 0;      //initialize local variable GradeCounter
        double dTotal = 0.0;         //initialize local variable dTotal
        double dGrade;                //delcare local variable dGrade
        double dAverage = 0;        //initialize local variable dAverage
        //dGrade = 100.0; Test
        dGrade = Double.parseDouble(JOptionPane.showInputDialog("Please enter your grade or -1 to quit:"));  //enter 1st numerical grade and parse as double
        
        while (dGrade != -1)     //-1 is the sentinel
        {
            dTotal = dTotal + dGrade;        //total grade
            dGradeCounter = dGradeCounter +1;      //counter
            
            dGrade = Double.parseDouble(JOptionPane.showInputDialog("Please enter your grade or -1 to quit:"));   // continue entering grades
            //dGrade= -1; Test
        } //end of loop
        
        //calculating average Grade
        if (dGradeCounter != 0)      
        {
            dAverage = dTotal / dGradeCounter;   //calculate average grade                          
        }
        return dAverage;    //return  double dAverage.

I have limited experience with it, but the API seemed really clumsy to me, and it looks like nobody anywhere gave a fuck about properly encapsulating things.

>>57375634

More clumsy than Vim's? Man, it's like we live in two different universes.
Emacs's API seemed to make quite a lot of sense to me, but I don't a whole lot of experience with it either.
>and it looks like nobody anywhere gave a fuck about properly encapsulating
Yeah I kinda agree with you here.

    Iterative_Day := Noramal_Day'Val(Days'Pos(First_Day) rem 7);

    if Is_Leap_Year(Year_Input) then
        Day_Array(February) := Day_Array(February) + 1;
    end if;

    for I in Months loop
        Put_Line(Months'Image(I));

>>57375763
That doesn't seem "clean", seems like a hack, especially if all you want is for the user to be able to input "Sun" and Get returning Sunday. Sounds more like you should just implement a Get function.

>>57375932
why do you hate it?

Ultimately you will learn that a language is a tool; you use the best tool for whatever you have to do. Python is the best one if you want to learn programming concepts.

Every OOP is shit anyways so try Haskell if you want to be a smartie.

>>57375961
THIS

Try to stay away from an OO language because any learning resource related to that language will mostly focus on masturbating to classes and design patterns without actually getting anything done.

>>57375936
It's not that bad. The proper way would be more complicated, taking in a string and comparing them the two different enumerations and then returning the main enumeration you want to use.

>>57374547
D deprecates C++ for the majority of use cases.

>>57376024
why?

Please help. What am I doing wrong here?
I'm trying to get the average of the values in the array.

        double dTotal = 0;
        double dAverage = 0;
        double[] dGrades =  new double[10];
        for (int i = 0; i < dGrades.length; i++)
        {
            dGrades[i] = Double.parseDouble(JOptionPane.showInputDialog("Enter your grades"));
            dTotal = dTotal + dGrades[i];
            dAverage = dTotal /dGrades.length;            
        }
        return dAverage;

>>57374536
I'm making my own programming language.

I have the parser taking my language fine, and I am using LLVM for the backend, which I already have set up.

The problem that I have, is I have no idea how exactly am I going to do semantic analysis.

The more I read into it, the more abstract it becomes with no simple implementations in sight. I saw one on github that was supposed to be a "simple" typechecker. Contained more LOC than the rest of my entire project.

>>57376059
Seems ok to me although a bit inefficient (the division should happen after the loop is done).
What's the issue?

>>57376021
>not that bad
>enumeration with more values that it actually is supposed to represent just to kludge user input
its pretty bad

>taking in a string and comparing them the two different enumerations
It should just be something like

if UserInput = "Sun" or UserInput = "Sunday" then
   return Sunday;
end if;

and not having Sun and Sunday being different values. Tying user input to source code symbols isn't usually that great anyway, and then you further break the idea by needing to introduce that modulo to get the "real" value

>>57376059
I haven't written any Java in a long-time.

But debug it like this:
Is the return value of your input correct?
Does dGrades.length do what you think it does?

Got tired of the nag screen in VFX Forth free version so I decided to have a go at patching it out.
There isn't any checking for a valid license or anything, the evaluation version is just a different binary so a hackish nop fill of the nagging is all you could do.

Why would it matter regarding the final calculated value? He always overwrites the previous value.

Although it might be that length gives back 9 instead of 10 aka the last index. I haven't programmed in Java in a long time.

>>57376194
I prefer focusing on getting proficient with one language instead of halfassing new languages.

>>57376214
doesn't it take time to initially memorize the concepts while writing those algorithms?

It's not just coding errors. If it's something like a missing semi colon, I can understand. This Bitch gets basic concepts wrong

>>57376063
I would suggest familiarizing yourself with the simply-typed lambda calculus. You'll learn about basic stuff like term/type syntax, judgements, contexts, inference rules, reduction, etc. which are all important to any kind of type checking.

For instance, consider the (single-parameter) simple function type A -> B, where A and B are types. This is expressed by the type rule:

G |- A type   G |- B type
-------------------------
    G |- A -> B type

You then have functions themselves:

G |- a : A   G, a : A |- b : B
------------------------------
      G |- λa.b : A -> B

This rule means that a lambda expression λa.b has the type A -> B if a has the type A and b, a term where a variable a is bound with the type A, has the type B.

The type checking algorithm, given a term λa.b, would first check that the type given is of the form A -> B. It would then extend the context with a variable a with the type A, and check that the term b has the type B recursively.

This is all rather straightforward to do with a functional language like Haskell or ML, but it gets tricky without algebraic data types and pattern matching.

data Term = Variable String | Lambda String Term | ...
data Type = Arrow Type Type | ... deriving Eq

type Context = String -> Type
extend :: String -> Type -> Context -> Context
extend x a g y
  | x == y = a
    | otherwise = g x

check :: Context -> Term -> Type -> Bool
check g (Variable x) a = g x == a
check g (Lambda x t) (Arrow a b) = check (extend x a g) t b
check g (Lambda _ _) _ = False
check ...

>>57376307
That's chump change

>>57376374
For example, she didn't realize that once a variable leaves a scope it was defined in, i.e. a for loop, that you can't access it anymore

>>57376385
Could you give an example of what you consider a wrong basic concept?

>>57376385

If I was you, I would take a teachers incompetency personally

>>57376063
>>57376391
Essentially, the term/type syntax and inference rules translate directly to your AST and type checking algorithm.

>>57376407
>>57376403

What game should I buy on steam?

>>57376194
I study 1-3 languages/frameworks/technologies at once, only about 15 minutes per day on each language/framework/technology. I find that it is difficult to absorb more information about a language after 15 minutes of study, i.e., I stop taking information after 15 minutes of focus. Then I try to immediately apply what I learned in the language/framework/technology in some small project or exercise. The point I've found is to have some part of your mind which at one point knew something, even though you may forget the specifics, so that you can recognize it as a solution to some problem in the future. The second time you learn it, after recognizing it is fitting for a solution to some problem, it is cemented in your mind. This works for functions, syntax, patterns, techniques, whatever. Whereas if you fly through a book, you don't get the depth on each individual feature, and you end up having to re-learn the same thing ten times. Even when I want to fly through a book, I go section by section every day, which means each new book takes about a month. A book in this case would be a classic text under 400 pages. Anything over 400 pages is a reference and shouldn't be studied using this technique.

>>57376109

implementing a hashmap why the hell am i getting -1 for index?

 int index = key.hashCode() % values.length; 

>>57376672
Is hashCode a signed int?
It's not guaranteed not to be negative, just unique.

>>57376631
better idea:
implement some kind of shitty psuedo onion routing using dns or icmp tunnels.

>>57376672
The hash code can be negative, and negative numbers give negative remainders.

Math.abs(key.hashCode()) % values.length

is a common but incorrect workaround.

Math.abs(key.hashCode() % values.length)

is mostly ok.

>>57376685
It's not guaranteed to be unique, it's only guaranteed (by unenforced contract) to be equal when the objects are .equals().

In particular, it's not guaranteed to be different if the objects are different.

int hashCode() { return 42; }

is a 100% valid and correct implementation.

Ok so A-F works, but 0-9 doesn't. No idea why.

unsigned long int hex2dec(const char *hex)
{
    int sum = 0;  
    int v= 0;
    int n=strlen(hex);                
    for (int i = 0; i<n; ++i)        
    {    
        if(((hex[i] >= '0') && (hex[i] <= '9')))
        {
            v = hex[i] - 0;
        }    
        else
        {
            v = hex[i] - 'A' + 10;
        }
        sum += (v * pow(16, n-1-i));
    }
    return sum; 
}

>>57376745
Thanks for that! Very helpful.

>>57376754

v = hex[i] - 0;

You're subtracting 0, not '0'

>>57376764
why is that?

>>57376813
Not anon posting the solution but I believe the 0 in single quotes is a different value than the 0 without

>>57376813
0 is 0
'0' is 48

>>57376754
You're also not checking correctly if the "else" is within 'A' and 'F' or 'a' and 'f'.

try:

if(hex[i] >= '0' && hex[i] <= '9')
{
    v = hex[i] - '0';
}    
else if(hex[i] >= 'A' && hex[i] <= 'F')
{
    v = hex[i] - 'A' + 10;
}
else if(hex[i] >= 'a' && hex[i] <= 'f')
{
    v = hex[i] - 'a' + 10;
}

Also, don't use pow when you can shift!
Luckily as 16 is a power of 2, you can emulate the pow by shifting by 4 (because 2^4 = 16) plus n-i (I believe)

sum += v << (4*(n-i));

There is no such language. The fact that anything could make you cry proves you're a subhuman who cannot program.

Hey /dpt/, could you help me out?

Pic related is my own compiler's parser's output and the source code it's reading. I know my toy C-like language grammar is slightly weird, but...anyway.

I'm testing my parser. It's written in C, and as much as I used valgrind and profiled the shit out of it, that doesn't protect me against potential mistakes I've made, ones that don't surface in my limited testing scope.

So I'm asking you this: could you write some bullshit C-looking code that I can use to test? Doesn't have to be a lot. Simple language constructs are sufficient (pointers aren't a thing that i'm going after), so function calls, math, loops...

Things that don't work:
1) else statements. I forgot to reserve the token when I was first writing my lexer, and didn't want to distract myself when the mistake came up later on
2) ++ and -- don't exist. Use += 1 and -= 1. Low priority but will fix.
3) Any kind of analysis. So far, this only checks if the code's grammar is valid, not even whether variables were declared etc.

/dpt/ newbie here, I have been working with a C file, but I need to compile it as a C++ file

Anyway to do that on codeblocks? I try to change the environment to compile to C++ but it swaps back to GCC/C compiler automatically.

Should I just create a new project as C++ as paste the code there?

You can't pre-fill the tty driver's input buffer.

You'd need to put the terminal into raw mode and handle individual key presses (including backspace) yourself.

The readline library (which does a similar thing but with a lot more editing functionality) will probably let you pre-fill the buffer. However, note that readline is GPL (not LGPL).

It doesn't work like that. If you don't have even a passing knowledge of the theory, you won't even realise that there's some theory out there which deals with your problem so you won't know that you should be looking anything up.

I'm writing a simple object to parse a configuration file for my GUI program. It's not the type of program that is going to be running as a daemon or for a long time. It would be marginally easier to write my program to open the file for writing the entire time the object exists (and this the application is loaded), and then close it in the destructor as I'm following C++ RAII programming. It also means less PEBKAC could occur. Should I do that, or is it better practise to simply open the file stream and close it when needed? Each member function is a run > do something > return, and they don't all need to write, sometimes only read, which is probably a good argument for that way too.

That's because they're very isolated from reality.
In theory, you shouldn't ever need to use a function break. It's short-circuiting and "ideal" code shouldn't do that.
But that's a stupid thing to try and accomplish in real code.

I'd assume O(n) with n being the length of the string.
For an actual time number it depends on if the data is cached or not, the speed of access, etc.

i want to post a blog post to help some beginners understand the use of git add -p and i wrote my draft in markdown, what do you all look for in programming articles?

>>57379862
You see how when you put in 888888888888888 it prints back out an error with 8.8888888E11?
It's an issue with the float data type.
You could maybe store the next input as a string, check it's length, and determine what to store it as from that.

Also, your second number is being checked for ints and stored as double. You should make it match the first input for consistency.

>>57379871
wouldn't it be O(1) in the case that the string might be the prefix of a much longer string? or if it's an empty string or an empty trie?

>>57379896
I assumed you were doing per character.
Sure if you got a thing that has the entire string as key/prefix it would be O(1)

          {
           
          System.out.println("Enter your calculation: ");
  
                firstNumb = in.nextDouble();
         
                operation = in.next().charAt(0);
  
                secondNumb = in.nextDouble();

            catch(Exception e)

              System.out.println("Error: improper formatting detected");
              break;
            }

Now if you try to throw in a fuck huge number, after the second input you get the error. I guess the program is still storing huge numbers for some odd reason.

and thanks for pointing out the int, I didn't even notice that.

Your question is underspecified. It doesn't say what should happen if the strings are different lengths, and the longer string contains a vowel near the end.
My program will "match" if it does not contain a vowel, and will not "match" if it does.

Are you writing just a simple formatter, or are you going to actually implement all of the different printf flags and features?

Yea, I'm actually trying to reimplement all the flags and features. I did some work already, but I want I'm not sure about the general direction my code should take. I start by getting all the differents flags in a structure and then using a array of pointer to functions to call the right function. It's pretty spaghetti I feel.

In Ruby it's super easy to use C.

require 'inline'

class InlineTest
  inline do |builder|
    builder.include '<math.h>'
    builder.c '
      int inline_pow(int a, int n) {
        return pow(a, n);
      }'
    builder.c '
      long inline_factorial(int max) {
        int i=max, result=1;
        while (i >= 2) { result *= i--; }
        return result;
      }'
  end
end

puts InlineTest.new.inline_factorial(5)
puts InlineTest.new.inline_pow(2, 10)

There are also way to use external C classes. For an overview see:

No, honestly, Vue.js 2.x is currently the hottest framework.
It's even easier than the original Angular.js, with a better performance, memory usage and ease of development compared to react.
Besides that it's comfortable to develop vue outside of the nodejs/npm ecosystem. Plain old or modern JS is enough, if that's what you fancy.

Gzipped, react is twice as big as vue.js, non minified it's 5 times as big, which speaks volumes about code quality. React is a mess.
Vue.js is practically developed by a single person (it's creator), just like vue-router, vuex and the vue development Chrome extension.

The vue.js documentation is stellar.

The best way to remember things is to actually need them for something; that is, to use the syntax in a project.
