I don't suppose you'd be alright with posting your github for me to look at would you?

I have my first programming interview today. I'm studying everything, have no idea what I am doing and terrified.

Working on something that's taken 3-4 weeks when I could've gotten it done in 1 week if I had known the ideal design and not the fake BS of "Feel free to do what you want, I'll just add a tidbit ;)"

>>57508367
Had a similar experience--it WILL suck and you will freak out but you will learn a lot.

Just try to be as calm as possible and be confident. Assuming this is an internship interview, just chill and realize that by studying you are already ahead of the pack. Your interviewers should be forgiving and if they aren't you don't want to work there.

Reposting from previous thread. What should I do if I can't pick between C and C++?

>>57508402
Pick C.

>>57508402
What do you want to do? If you're not interested in high-performance, embedded systems programming, or working close to the machine level I would avoid C.

C++ has more applications and you'll be able to find more jobs with it as well.

It's ultimately depends on what you want to do.

also >learn both

>>57508402
C++

Otherwise master the language you already know. You should be able to pick up either fairly quick if needbe

>>57508406
Is this a confirmed post though?
>>57508413
>also >learn both
That's also a possibility. Which one should I start learning first?
I don't think I'm that interested in a programming job tb h but that might change.
>>57508438
I don't know anything but a little bit of C.

>>57508452
what do you do now? what are you interested in doing with programming if not getting a job?

I think python is a much better hobby language.

I love physical copies of books but goddamn why are they so fucking expensive. I understand that digital is better and free but physical really gets my dick hard. Is there anywhere selling classic good books for cheap?

>>57508470
I want to make an anime file sorter.

>>57508470
I do something not related to programming. Just for fun
>I think python is a much better hobby language.
In what way?

>>57508484
Just use python, it's way easier. You don't need to use C or C++ for shit like that.

Being able to abstract away garbage collection and other C/C++ difficulties is better if you just wanna do normal stuff.

Or just use whatever terminal language you have (bash if you're on *nix, batch on windows) if it's not complicated.

>>57508495
Oh, that post was a trole.

I like python because you can abstract away the parts of C++ and similar languages that prime those for performance. One of the people on the C++ standards committee once said (paraphrased) "we built this language for power grids etc."
Here's an interesting panel on systems programming languages you might be interested in for more information on these concepts: https://www.youtube.com/watch?v=BBbv1ej0fFo

Python is a scripting language with a large standard library, easy and natural syntax, and is really fun to use. The main drawback is that it's slow.

>>57508378
It's not unfortunately, but it's thankfully just focusing on regression testing and QA. I looked up my interviewers and every one of them is a PhD with a million publications and I am just some NEET who has made a few scripts.
If I can't answer the white boarding questions what should I do? Just walk through my thought process and hope they forgive me?

>>57508517
The experience I referenced was only a month ago. I have only one interview. There are people wiser than me on the internet who have discussed these issues at length. You should consider googling this or posting on /r/cscareerquestions or similar.

What I will say is this: keep in mind that you got through the resume screen so you must have something they are looking for. Be confident and don't be intimidated by their education.

>>57508514
But that's not an issue for me. I'm somewhat of a genius when it comes to learning things I'm interested in pretty fast.

>>57508333
Try a better OP next time.

>>57508538
that's kind of pretentious, to be quite honest.

learn what you want, ultimately. I just think that the intricacies of learning pointers, memory allocation and polymorphism will bore you if you're not interested in solving problems that need those concepts.

>>57508333
I'm only good with javascript but currently learning node, python, ruby, bootstrap, hoping to master mvc and build web apps.. I've been looking at coding bootcamps. anyone has any experience with them?

>>57508555
>pretentious
You just lost any degree of authority you had by using such meaningless words.
>learn what you want, ultimately.
That's obvious, but I wanted to ask about choosing C or C++
>I just think that the intricacies of learning pointers, memory allocation and polymorphism will bore you
I don't think that will happen since this is something I'm interested in.

>>57508624
I mean I explained to you which was a better choice for different stuff.

Why come on here if you're going to act like an asshole? If you're so goddamn smart just learn both anyways.

>>57508631
Why come on here if you're going to be so sensitive?
I didn't say I was smart. I just said I learn stuff pretty fast if I care about it, which is true and not "pretentious" as you put it.
>just learn both anyways.
Which one should someone learn first if that's what they are planning to do in your opinion?

>>57508644
learn C because it's the foundation of all modern computing

Wtf does "Write a program in java using a text stream from standard input..."

text stream from standard input??

>>57509032
Probably using the standard text stream interface (whatever that is in Java) using the stdio rather than a file or whatever.

so in python if I had

def a():
a = "b"
def c():
print (a)

c()

would that output "b"?

Yeah so wrote a base64 encoder/decoder just for the hell of it. (Posted it before, but there was a small bug).

http://paste.debian.net/895474/

>>57509079
>would that output "b"?
No, because you have a syntax error.

>>57509079
isn't that gonna throw an exception because of improper indentation?

>>57509107
>>57509111
ok let me rephrase, assuming I fixed it to have correct indentation and no syntax errors would it work?

>>57509032
>how do i google

>>57509120
well run it.
I did and it didn't work.

>>57509122
but can standard input just be like input from the console using Scanner?

>>57509120
>correct indentation
A Python program is meaningless without indentation.
It's literally the same as posting some C-like code without curly brackets.

There are many ways you can indent your code to create different "correct" programs.

>>57509120
Assuming you indent

def a():
    a = 'b'

def c():
    print(a)

it will print "<function a at someaddress>"
because thats how it is within the scope of c

if you code c as an embedded function

def a():
    a = 'b'
    def c():
        print(a)

then it will print 'b' as c is embedded in a and thus has access to its scope.

>>57509079
Try this

def a():
    global a
    a = "b"

def c():
    print(a)

c()
a()
c()

Guess what the values of these expressions are.

True == True
False == True

>>57509818
what about if the value is 1? that's not equal to True.

>>57508452
>Is this a confirmed post though?
Not really sure what this means, but coming from another anon who picked up C -> C++ -> Java: go with C first. It teaches you the fundamentals that you should be familiar with, so you know how the higher-level abstractions from other languages work.

>>57510022
It's not even good for cutting edge AI. Logic-based AI is cool and all but it's a dead meme desu, all about stats these days

>>57509966
>Also, is that generally viewed as bad practice, when working with version control?
Of course it is - a human readable binary diff is worth fuckall, because the binary code isn't a useful representation. Binary diffs are useful for deploying as patches, not for maintaining as a versioned changelog.

>>57510057
eh, AI sounded interesting, so i enrolled for the module on it, and prolog is what we were taught

so i have this:

#include <iostream>
using namespace std;
int main() {
  string input;
  cin >> input;
  cout << input << endl;
}

when i write "Hello World" with cin, cout writes

Hello
World

but i want it to be

Hello World

>>57509501
The truth is right here.

>>57510152
Use getline, maybe.

>>57510152
std::cin interprets a space as a seperator. Try using std::getline to get it until the return. Also, don't put

using namespace std;

>>57510619
why not?

>>57510300
Only std::cin and spaces. std::cout, std::stringstream and file streams are all very useful

>>57510633
No, they're just as shit.
iostreams are the prime example for why operator overloading is just a fucking bad idea.

What the fuck Python? I'm trying to find the index of the last / character in a file path, but:

>>> path = "/home/anon/example/folder/file"
>>> print path.find("/")
0
>>> print path.find("/", len(path) - 1, 0)
-1
>>> print path.find("/", 0, -len(path)
-1
>>> print path.find("/", len(path) - 1, -len(path)
-1

First one was obviously going to be 0 as find with no additional parameters just searches the entire string from left to right.
Second one I would have hoped would maybe recognize that beginning > end and search the string right-to-left. It didn't.
Third one, similar. Indexing from 0 to -len(path) probably results in a string of len < 0 = "".
Fourth one, same.

TL;DR:
How do I make Python's string.find-function search right-to-left? Should I just flip the string backwards (expensive operation) and search left-to-right?

Currently working in Xamarin Forms. You know to make a cross platform app? Although some FREAKING GENIUS decided that we should only release the iOS version.

Question, what should we be using instead of Xamarin forms? I want something that I could learn in a couple of weeks.

I had a Xamarin.Forms app working on Android and iOS in like 20 minutes last week.

>>57513325
Abstraction makes it easier to express a lot in little typing. (when you've written your abstraction stuff in languages, as they provide very poor facilities for you to actually write anything efficiently it's often a waste of time)

But it rarely lets you solve the problems in good ways because writing good API is hard. Knowing the project in detail from the start is hard etc etc. Basically you're hanging your work on a very loose guess when you do abstract programming.
So you tend to try and mash your square program into a differently shaped hole.
And you may get it through to the other end with a lot of work but the person who tried the different pieces/measured the hole and then wrote the program will have much more success.

>>57512987

>>57513456
When you begin a Xamarin Forms project properly, you should have multiple projects in a VS solution. One project is your shared code, and there's one for each platform (XBone, Android, iOS, WP).

I'm not sure how your project was initiated, but it's stupid easy to get the same thing working on multiplat if you start it right.

""" denotes a docstring in Python. Try just ".

>>57513469
Saving typing is about the least relevant property of abstraction.

The main reason to abstract is to reduce coupling, so that you don't need to understand the entire system in detail before you can work on any part of it, so that you don't have to re-write half the system whenever one detail changes, so that you don't have to wait for every detail to be decided before implementing anything, etc.

I'm trying to generate a Quake 3 player config file via a Python script (for now); they're essentially text files. How do I handle such a large volume of input on the command line if I'm not jumping straight into a GUI? For instance, this is just one chunk and it deals specifically with pure player information:

// Player

seta name    "name"
seta nick      "nick"
seta ch_file    "hud1"
seta sex      "male"
seta headmodel    "bones"

Even a lot of nice schools are like that, it's all about what you do. Just because you go to a party school doesn't mean you can't learn a lot and actually might mean it's easier for you to get an internship or research project that your classmates.

        for(int i = 0; i < matrix.length; i++)
        {
            // Pull a vertex out of the queue and add it to the topological sort.
            int node = q.remove();
            hashString = hashString + node;
            
            // All vertices we can reach via an edge from the current vertex should have
            // their incoming edge counts decremented. If one of these hits zero, add
            // it to the queue, as it's ready to be included in our topological sort.
            for(int i = 0; i < matrix.length; i++)
                if(matrix[node][i] && --incoming[i] == 0)

They already are, though.

A computer playing any shooter can immediately identify a target and get a headshot quicker than any human would be able to react.

The only advantage a human may have is the ability to stay out of the line of sight of a machine, but with positional audio cues, a player would have to stay crouched the entire game and if they fire, it must be a one shot kill every time.

How do computers react to changing situations and ploys?
For example, I throw a grenade in one direction to distract the computer, and then sprint out under the cover of the detonation's noise and quickly fire upon the target. Do they possess the intelligence to recognize tactics like that or would they get caught out?

>>57514445
Yes, that's trivial.

Why would a computer be "distracted" by a grenade? It's not a valid target.

There is a very specific set of possible pixel maps that represent a player character, and a grenade would not match.

The only action AI would take to a grenade is simply to avoid it, but this would not hinder its aim, outside of runwalk spread.

>>57514471
The grenade is to drown out the audio cues from the footsteps so as to leave it unaware of my current position (that is, about to round the corner and enter line of sight)
Although I worry that computers are already at the point they can pick out the individual noise of footsteps from the cacophony of explosions and gunfire.

inb4 the computer just does constant 360s in the span of a second or less to scan the entire area and no amount of audio masking will save me from rape.

Depends on what you mean by "meme hate".

I like C#.

I don't like C++.

That being said, I haven't used C++ in quite a while. Last time I used it, it silently stuffed a float into an integer (destroying data in the process), and cin/cout worked in a way that left me dumbfounded.

I don't mind managing memory, but I prefer my memory to be managed by default, with the option to take over manually when I see a need.

Maybe I'm just too stupid for C++. Either way, I've managed to get by just fine with C#.

>>57514546
No shit. But if they hate the convenience that c++ provides over c, then they should super hate the super convenience that c# provides.

I put my functions in another file. Those are my prototypes.

here you go, little noob. note that we dont check for valid input so the program cashes if the user inputs something other than a whole number. also due to the way we are using cin, the program can take multiple values if input correctly, so for example "2 50 100" will work and go straight to the end of the program.

double IntegerArrayAverage(int * array, int size)
{
    double average = 0;  
     
    for (int i = 0; i < size; i++)
    {
        average += array[i];   
    }
    
    average = (average / size);  
      
    return average;
}


int main() 
{
    int size = 0;
      
    cout << "How many values to take for average? ";
    
    cin >> size;
    int * iArray = new  int[size];
    
    for (int i = 0; i < size; i++)
    {
        cout << "Input value for element number " << (i + 1) << "." << endl;
        cin >> iArray[i];
    }

    cout << "The average is " << setprecision(1) << fixed << IntegerArrayAverage(iArray, size) << endl;

    delete[] iArray;
    
    cin >> size; //pause the console
    return 0;
}

Learning phyton,c, and c++.
C seems pretty easy, c++ seems a little bit more tedious but its not so bad. Phython...eh...

C++ is truly awful

static void Main(string[] args)
{
    while(true)
    {
        Write("Enter space seperated whole numbers to average: ");
        try
        {
            WriteLine($"Average: {Array.ConvertAll(ReadLine().Split(' '), int.Parse).Average()}");
        }
        catch
        {
            WriteLine("Invalid Input.");
        }
    }
}

If only there were a datatype JUST for that purpose...

Nah, lets continue writing exploitable code like the fucking pajeet you are.

Working on a shitty android app to put on my resume.

Its a note taking app (what a surprise) that allows you to take notes and add #hashtags and @mentions to organize things better.

This is not the final design, i just used those views to test the hashtags and mentions

Functions in lisps are closures over values. What you call a local variable in given function is basically variable in that closure (closure is basically envirovment).

You can use lambdas to preserve closures and thus implement lists using them. It's totally inefficient approach, but purest.

cons return a closure that takes a procedure as argument to apply x y to it.

(cons 1 2) -> (lambda (m) (m 1 2))

if you then apply to that closure the following procedure

(lambda (x y) x)

, you get 1.
if you apply

(lambda (x y) y)

, you get 2

C standard never said size_t is for array indexing. especially that there no such thing as "array indexing" in C but only pointer arithmetic. reminder, the [] operator is syntax sugar for *((a)+(b))

I need help, when someone says
>flushing the input stream
what exactly do they mean?
Before I put

cin.ignore();

it wouldn't work. I just want to understand why. What does

cin.ignore();

ignore specifically? Here's the code

{
    string user_Firstname;

    cout << "Now Please enter your first name: ";
    cin >> user_Firstname;
    cout << "You entered: " << user_Firstname << "\n\n";

    cin.ignore(); //FlUSHES THE INPUT STREAM (whatever that means)

    cout << "Now please type your full name: ";
    string user_Fullname;
    getline (cin,user_Fullname);
    cout << "You entered: " << user_Fullname << "\n\n";

    cout << "You should give me a name as well: ";
    string narrator_Nameinput;
    getline (cin,narrator_Nameinput);
    cout << "You entered: " << narrator_Nameinput << "\n";

    return 0;
}

Um, can you not question the language please?

It's been around for a long time and doesn't need to be justified to people like you.

Uhhh

I understand nothing.

>>57515909
Well it's no fun to take something as what it is without understanding why. I'll just keep searching.

>>57515893
when you use cin >> user_firstname, the program takes the first word from the input stream and puts it in the variable, so what ever is left in the input buffer stays in there until you clear it or use cin again.

So if I had

cin >> string1;
cin>> string2;

the user could input "two words" and the program would instantly put "two" into string1and "words" into string2.

uhh what? that's just a procedure argument. read the semantics of the [] operator if you are able to (which i doubt), dumbtard.

>>57516017
That's the best explanation i've gotten. Gonna throw that in to my notes, thanks a lot.

double func1(x, y){
 double sum = 0.0; 
 sum = x/ y; 

 return sum; 

}
double func2 (a, b){
 //sum from the first function

double total = 0.0; 

total = sum + a + b; 

return total; 

}

how do I get the result from the first function so that I could use it in the second function?
