>>59430399
not meant to be rude, but this picture is fucking annoying, why reposting the same pic every day

>>59430444
python is the best to get it done

once it's done you can use Rust/Java/D/C++ to rewrite it

>>59430457
This is called rapid prototyping, it's what python is very good for.

You can translate it to Nim, it compiles to C. Best of both worlds

would you say ruby is better than python?
so far it feels better for me since it feels like python without whitespace, don't have much experience with ruby, shoul I switch?

>>59430467
wait so nim takes straight python? you don't need to write a nim variant?

>>59430430
That's a weird way of saying Lisp.

>>59430265

?

>>59430483
Nim's syntax is incredibly similar to that of python and you can learn it quickly if you are used to python.

Finding common substrings between two strings. Now I only have to add a method to return the biggest one.

void main(string[] args){

    string str1 = "abcder";
    string str2 = "xwbcmaabcr";
    string[] commons;

    for (int i = 0; i < str1.length; i++){
        for (int j = 0; j < str2.length; j++){
            if (str2[j]==str1[i]){
                string current = ""~str1[i];
                for (int a = 1; (a+i < str1.length && a+j < str2.length); a++){
                    if(str2[a+j]==str1[a+i]){
                        current~=str1[a+i];

This is true.

I just decided to start using checkstyle, it had at shitfit about using tabs and when I changed to spaces, it had a fit about it using 4 spaces not 2, so I changed that too.

Do a collection of strings, mate. Then you can do this for any number of strings, rather than be stuck with two.

Static types merely hinder the programmer, forcing him to bend to the will of the compiler, rather than the other way around, like it should be. A programmer should be allowed to sketch his ideas freely without the fear of upsetting a perpetually angry static type system.

you already know programming (i hope) all you are learning is a new standard library and syntax, books will just harp on about data structures and algorithms.

>>59434150
even experienced python programers will benefit from reading a good boodl. python has a number of gotchas and best practices that are not obvious to people from other languages. the fact that you think you can learn everything via trail-and-stackoverflow is somewhat worrying

>>59434150
stupid comment but true

Quick question.

string s = "";
            string x = "%";
            int y = 0;
            Stopwatch test = new Stopwatch();
            test.Start();
            for (int i = 0; i < 1000; i++)
            {
                Thread.Sleep(1);
                if (i % 100 == 0)
                {
                    y = y + 10;
                    s = s + "-";
                    Console.Write(s+y+x);
                }
            }
            test.Stop();
            Console.ReadKey();

Instead of -10%--20%---30%----40% etc, how do I make it so that it shows ----40% etc, but changing constantly.

What advice would you give to someone who has to understand a complex project made by someone else?

I'm a beginner at Spring and I'll have to work on a project already made for my internship. I understand most of the things but not how to project works (like what this class does and for wich purpose)

It's the first time I'm working on someone else project so I was wondering if there was a correct methodology on this.

When is it "allowed" to use a singleton?

I'm writing a game (and its accompanying engine) in order to learn OpenGL, and have a class called ResourceManager that's used for managing resources (textures, materials, various game data, etc) whenever another class needs to load or fetch loaded resources.

Since almost every class accesses some resources, up until now I've been passing a reference to the resource manager in every constructor where it's needed. What would the disadvantages be if I were to transform it into a singleton instead of passing references all over the place?

>>59434255
And here I thought our super smart turbo (((expert))) kernel hacker master C programmers don't make mistakes

>>59434393
Passing argument is more flexible but it's cumbersome and less optimal (except if the compiler is a marvel).

>>59434427
>Passing argument is more flexible
In what way? I find it quite tedious to pass it around to over 9000 intermediary classes just because another class at the other end have to use it a single time.

>>59434505
>In what way?
You can, when you want, change it, duplicate it etc. But if you'll never need that just it would be useless.

>>59434393
>>59434505
>when should I use global state?
when it makes sense

>>59434520
Ah, yes, I see. If that's the major advantage of not turning it into a singleton, I'll probably turn it into one. It never changes, which means that I really can't find any downsides of making it into a singleton.

>>59434558
Obviously. I just wanted to make sure I hadn't neglected any aspects.

I'm trying to free up an array of pointers in C, and running valgrind comes back clean.
However, to do this, because I don't know what indices have been allocated to and which ones haven't when I'm freeing, I'm doing

if (ptrarr[i] != NULL)
    free (ptrarr[i]);

inside of a for loop.

This spits back

Conditional move or jump depends on uninitialized value(s)

Reading the valgrind documentation tells me that this error could be serious or fairly innocuous, as it just means the execution of the program went down a different branch due to said uninitialized value.
Since I'm basically checking to see if that index is initialized or not, that's obviously what's happening. If it finds one that isn't, then it does something different.

TL;DR Is there a better way to check if a pointer has been allocated or not than doing an if != NULL check?

>>59434622
as long as you initialized all pointers as NULL you should be ok.

>>59434622
Always NULL the pointers if they're not going to be used immediately.

>what actually \r does?
In a classic typewriter, you had to carial return, to have the “cursor” back to the 1st char, then line feed to get to the next line. That’s why you have to get CR+LF at the end of a line on Win to get a “true newline”. Nowadays, in the UNIX world, and maybe in the Win terminal too, \r “return” to the beginning of the line, so that you can “write over” the previously written text, and that precisely what you’re looking for. So, just add it at the beginning of your text

>>59434318
So? You can draw with console. A loading bar like this is fine.

>>59434335
Thank you.

>>59434600
For a game you'll probably never need to duplicate or locally change the resource manager. So you can use a global variable. I just hope that you'll never regret it.

>>59434392
Depends. If you have access to another developer who knows the project, ask her questions like crazy. Otherwise, look at unit tests, pick a piece of text in the UI and trace it through the code to see how it got there (and repeat), drop debug statements everywhere, grep for usages...welcome to the nightmare of maintenance engineering

>>59434622
Oh and as a side question:
Is it even necessary to do != NULL? Can I just have if(ptrarr[i]), since if its not NULL or 0 it should be considered "true"?

>>59434646
>>59434666
I'm declaring the array as

char* ptrarr[LENGTH];

and assigning into each index with

ptrarr[i] = (char*)malloc(strlen(tok)+1);

Should I run a loop right after declaration to assign each to NULL or something?

>>59434684
>Instead of -10%--20%---30%----40% etc, how do I make it so that it shows ----40% etc, but changing constantly.
that's what you initially said you wanted, which isn't achievable by just a newline. a newline would make it
-- 10%
----20%
etc

you originally wanted it to be
--10%
and then the 1 magically changes to a 2 when it goes to 20%

>>59434705
Checking for NULL lets you and other readers instantly know you're checking for a null pointer, Keep it if you care about readability.

>>59434705
>Should I run a loop right after declaration to assign each to NULL or something?

most definitely

if you don't initialize with a value immediately always initialize to NULL

other wise you could just get random data

I wish anon, I wish.

But yeah I'm working with the team that created the project and they're pretty nice. It's just that sometimes I feel like a retard for asking questions with obvious answers (sometimes I block on something really stupid) but it's why internships were created so I'll just have to swalllow my pride instead of blocking for hours.
But yeah tracing shit is a good idea, I'll do that.

Because instead of losing your time finding a way to use the gimmicky features of certain languages you can actually focus on how your program will work using simple and meaningful elementary programming "bricks" much like building something with Lego.
>ASM can do that too
C removes most of the thing you have to worry about in ASM.
It is an excellent compromise between simplicity and powerfulness.
The people hating on C never tried to understand it. They prefer to hide their inability to write productive code behind a shitload of unnecessary concepts that makes you look clever when you brag about it online.
Never trust someone who hates C.

Does g++ compile these two code snippets into the same executable?

calculate1(foo());
calculate2(foo());

int n = foo();
calculate1(n);
calculate2(n);

I.e. does the two function calls in the first example get optimized into a single one?

C does not support closures at all, but it does support callbacks just fine. You don't need closures in order to make function composition useful, closures are often nothing more than a nice-to-have. Check out C's qsort for example. Another example is a dispatch tables.

>>59435413
"Callback" is often used in a more specific way than "function pointer". As for delegates, they allso allow multicasting, at least in C#'s implementation.

>>59435612
Most other features in HLL's are syntactic sugar from that POV, so it's a pretty pointless argument to make. What really makes a difference is usability. Baked in features are usually done with the whole language design in mind rather than as an afterthought (the obvious exception here being C++) and often leverage each other to make a cohesive whole.
