Isn't that math, how's this programming?

>>57045867
The no-loop thing isn't a requirement though, I was just wondering.
Anyway currently I fucked something up and it doesn't work.

#include <iostream>

using namespace std;

int main()
{
    float M0, r, N;
    cin >> M0 >> r >> N;
    
    for (int count; count < N; count++)
    {
        M0 = M0 + (M0 * (r/100));
    }
    cout << M0;
    
    return 0;
}

>>57045912

It's garbage, properly initialize it

your variable name doesn't describe the variable. also, people don't use underscores in variable names. if you want to remember the original amount, have a variable originalAmount, and then set another variable amount equal to it, and change that one

>So it was because count is some unknown value?

if this C/C++, if you don't set a value to a new variable, it's value will be whatever garbage was at that part of the memory where your new variable is now.
In other languages it might stay NULL and then your code would cause a NullPointerException.

For now remember to always set an initial value when creating a new variable

Nah, that's what i'm trying to write.

strings = [2, 5, 6, 4]
for i in range(len(strings), 0, -1):
    print(strings[i-1], sep="", end=""))

why does this print 4652?

I have no idea what the fuck happens in

for i in range(len(strings), 0, -1)

because it's the "i-1" part that turns the numbers around.

>>57046392
>it's the "i-1" part that turns the numbers around.
what did he mean by this?

>>57046392

think again

>>57046392
>len(strings)

Because you count backwards in the string
4 6 5 2 (no spaces ofc)

>>57046413

  print(strings[i-1], sep="", end=""))

notice the [i-1]?

>>57046415
I know the -1 starts on the other side, but why does it print 4652 and not 4256?

>>57046912
Yeah, that's probably true. I've definitely programmed in all sorts of languages, and when I don't know what's going on, I usually try to understand what's actually happening because it helps me learn better. So whenever I have an issue where I don't know what's going on, I figure out what's going on and when I fix it, I understand what's happening and why my program works. There's definitely a limit to my understanding, but I have a fairly good overall view of what's going on. I enjoyed my systems programming course.

Not

Tensorflow implementation of research stuff in 'real fast machine learning' area. Tensorflow is *really fucking great* until:

1. You have to do any kind of nontrivial indexing.
2. You have to convert your data to protos.

This is a problem because
1. Any interesting machine learning requires nontrivial indexing.
2. You aren't a computer and you can't read protos and converting all of your data to protos is a fucking insane waste of time because you are not personally The Google.

At least I'll never have to take a derivative again.

>>57046432
> second day programming btw

Sorry people are being dicks.

The way you called range produces [4, 3, 2, 1]. Because list indices are zero-indexed, these would be out of bounds if you used them without subtracting 1. You want your indices to be [3, 2, 1, 0].

Does that make sense?

Reposting not answered from old thread:
All the encryption connoiseurs here on this thread, tell me why this sucks.
I want to learn more about encryption so I'm trying to make a simmetric cypher on python3. It reads byte by byte and I'm working that out but meanwhile I try to generate a key that is: as big as the file, and has entropy I use a password.
First I though feeding the password as a seed to a random number generator like a good one (unless you use c++'s <random> with gcc on windows and realise you either torture yourself with mingw-w64 or use msvc), so I could have generated keys on the fly, now transferring the key is no problem.
Then I sha512 that password. If the length in bytes of the sha512 is inferior to the amount of bytes on the file, then we need a bigger key.
So what we do to make this key bigger and not having any other source for entropy rather than the hash of the password?
Well, concatenate the password with the previous hash of the password, and then... hash that.
That, until you have a big enough key.
So it works but now I'm not sure if what I'm doing is dirty as fuck.
The generated keys can be super big and still vary a lot from password to password without noticeable patterns.

The main problem with simmetric is the sharing of the key. But if I generate my key with a good source of entropy, why worry?
Also the method would be doing XOR over every byte of the file and every byte of the key.
So I'm just going to paste the code and just tell me...
Is this just fucking dirty as fuck? Cause I know it's not safe. Real encryption algorithms are nothing like a simple XOR. I just do it for learning.

I'm trying to avoid unnecessary duplication of testing code using TestNG in Java (using IntelliJ)
Right now the way it's set up is I have a fistful of constants at the top of the class, and am just repeating all the actual test case methods in every scenario file while editing the constants to reflect what I expect that change to do.

It's not that bad but it feels massively unnecessary. Is there a proper way to generate these files with TestNG or is this it?

>>57048810
Where does the word "maximum" come into play here? The dump already contains the maximum amount of information you can obtain from it.

Imagine you're an object for a second. Without compromising your understanding of OOP or programming or computation, etc, imagine you are this object and you have a regarded class definition. Now you want to check the time. You yourself could do that by simply checking your watch or your phone, and in order to do that you would have to reference your watch or phone. That could be described as Object.checkWatch() which would return the value from watch but what if you wanted to point out the watch's function to someone else? Well you'd have to Object->checkWatch() to point at it which might require a more discrete function process to relay the info properly.

Decide if you want to give up your method and be pidgeon-holed or if you want look through millions of pajeet comments to get the simple and straight answer. And of course the occassional asshole, me, that will try and gain some sympathy in the matter by helping you. Still, that's too much, it sounds like they are just having you make a graph and derive conclusions from the matrix data set derived from the graph configurations.

If you're a C programmer of average experience it's fairly easy to quickly see that the code presented will take arguments passed on the command line, make grand assumptions about them, then print some rows of asterisks to the standard output.

Using a lowercase letter "L" as a counter is a sure sign the author is just an asswipe, therefore deriving the exact output by actually taking any more second of one' life trying to understand the output code isn't worth anyone's time, since the author doesn't respect it anyway.

>Daily reminder that if you need comments your code is terrible

Did your mom give you the daily sigh from the top of the basement stairs today? The one she makes when she is wondering when you'll get a job or make something of your life?

>>57049603
The junk value is already in there. Just use the pointer and set the value to an int or parse that int.

>>57045625

I though that (since Java 8) you could add a bodyless static method to an interface. So why do I get
>static methods in interfaces should have a body
when I try to do this?

If this is not possible, then how can I make sure that certain classes have certain static methods implementations?

Can you make an Ascii Roguelike with the Tkinter module instead of pygame and other libraries?

>if you need comments your code is terrible
I had a classmate that was very opinionated on this point until i actually started to seriously try writing self documenting code. He changed his mind when he saw he had created a monster.

>>57049651

stop projecting

>>57049650
Walk into some companies, request an audience with people of high positions, and ask what skills they would want you to develop if you did work for them

>>57049654
That sounds like an Abstract Class rather than an interface.

>>57049666
I had a friend like this too. He would argue for a structure and that people won't like this or that, he does design for a living. After about 2 quick little classes he realized that the design I was proposing would do his job for him. He stopped talking to me for a while and only recently we started talking again. He immediately started trying to place me below him. I just blocked him. I don't need more of that in my life. Especially if I'm doing all the work.

>>57049669
Is that an indirect yes ir are you just not answering my question?

>>57049715
He's hinting at test driven development of your life.

>>57049715
Doesn't matter. The answer is now definitely "No"

>>57049667

If a program doesn't need comments, it isn't doing much of anything.

> don't live with mum no more

But still a zealously idealistic....what now? What is it you're doing with yourself that makes your words worth anything?

>>57049677
Maybe I should do something like this:

>abstract class Fruit
>abstract class SpecialFruit extends Fruit
>class Apple extends Fruit
>class Banana extends SpecialFruit

with SpecialFruit containing the bodyless Static methods I need for special fruits. Then I can implement them specifically for classes like Banana. Would that compile?

is the market for entry-level software developers good or bad?

Don't be entry-level. Start some projects, commit to others', have ANY experience before you seeking employment.

I have 2 shitty apps and 1 decent app (in terms of code, scope, function, etc.) on apple's app store
one of the shitty ones is extremely popular
but my only work experience is burger king (lol)
I'm an underachieving slacker
pls help

>>57049747
Why not create a separate category that applies to Banana as something instead of fruit.

It's more specific on the basis of being an apple and then a more special fruit, not that it is a special fruit that only this special fruit can reach the state of banana.

An abstraction is a pull from an existing thing. You don't grow to that state. You grow to a similar state but only in matter. You must extract and abstract in order to fully represent what you are modeling. You can't make men if you take man-like behavior out of the model.

Static methods are essentially accessing read only memory and so need to exact a memory table that will function only as such. In order to do that, the rest of the data table must coordinate about the static data, not the other way around.

>>57049785
>I feel like I'm doing something fundamentally wrong, but I can't seem to figure out what
You're using Java

>>57049747
you're a special fruit alright

>>57049823
Let's say banana is used towards something. Well, as we have abstracted the position of a banana in the larger scheme of life, we cannot readily assume that the banana came to be just so we would have potassium for the coming diabetes without first giving in to the full design inlaid before the prospective array in assembly. The matter isn't asymptotic.

FORCED OBJECT ORIENTATION

>>57049951
You get locked in oop-think, and end up trying to cram every problem into a design paradigm implementation that doesn't quite fit. Like you're doing now.
Because of this the standard library seems to unnecessarily complicate everything.

That, and checked exceptions.

>>57049994
>checked exceptions.

The worst offense. It makes development in C# so much better.

You're the one who taught me that what java does is called this.

In openGL, how do buffers work?

lets say I'm making a program in which things would spawn and despawn. Each time something appears, does it need to redefine a buffer and its size? Or can I just define a buffer of some limited size and not always use it all?

>>57049015
>python 2
you failed

>>57049015

> // in python

>>57049049
>>57049065
why shouldn't you use '?

>>57050128
Don't think of it in terms of storing objects in the buffer, but storing meshes. So if two objects share the same mesh, you just store the mesh once and apply different transformations to it. And yeah, you can keep meshes and textures in the buffer, ready to be used when you need them.

In C, how do you create your own library you can include?

I know I could probably compile one myself and that including is basically copy and pasting, but what actually is the acceptable way to do it? how does a .h file work?

>>57050365
That is the way to do it. Write implementation in c file. Provide prototypes in h file. Include h file in your project. Compile and link all source files.

It sounds to me that your next step should be to read about the linking step in the compile chain.

Why can't I link GLFW3 to my project

it gives error "cannot find corearb.h"

I had it running before but lost my linker options.. it took me hours to figure out before

>>57050365

/* mylib.c */
/* compile like this: gcc -c mylib.c */
/* the -c option compiles a mylib.o object without linking into an executable. */

/* static means blerb won't be visible outside of mylib */
static int blerb(int x)
{
  return 3*x;
}

int bleck(int x)
{
  return blerb(x) + 1;
}

/* main.c */
/* compile like this: gcc main.c mylib.o */
/* to link together with the compiled object from before. */

int bleck(int); /* this function will be defined *somewhere*, but C doesn't  
                   care where yet, it just needs the right type. */

void main(void)
{
  printf("%d", bleck(5));
}

This works fine, but usually you will have lots of functions and some custom data types, so it helps to have a header file that list all the prototypes:

/* mylib.h */

int bleck(int);

The you add

#include "mylib.h"

in main.c.
