Speaking about design patterns, it seems like everyone shits on gof book these days

I'm messing with vectors, arrays, struct and loops.

Here's my code.

struct Box
{
    int area;
    int weight;
}

std:vector<Box> blueboxes = {{5,10},{3,12},{4,7}};
std:vector<Box> redboxes = {{5,10},{3,12},{4,7}};

If I want to iterate through each of the blueboxes by area and then find out if weight is > 10, how would I do that?

trying to learn c++ but can't seem to find the equivalent foreach function nor a simple explanation.

welp.. I'll give it a try anyways, thanks.

I am comparing cards by creating bool function and then overloading an operator. However, it sucks when it comes about sorting and I have no idea.

This piece works well, if trump is Spades, then Ace of Clubs is beaten by Six of Spades, which works as intended.

  static bool cardCompare(Card& a, Card& b) {
      bool f(a._Suit != a._Trump and b._Suit == b._Trump);
      bool s((a._Suit == a._Trump and b._Suit == b._Trump) and (a._Value < b._Value));
      bool t((a._Suit == b._Suit) and (a._Value < b._Value));
      return f or s or t;
  }

  friend bool operator<(Card& a, Card& b) { return cardCompare(a, b);     };
  friend bool operator>(Card& a, Card& b) { return !(cardCompare(a, b));  };

How do fix sorting, it happens that I can't sort it in a vector quite well, trumps are the latest as intended, however, I want it group'd by suit, like
1. Six of Spades
2. Seven of Spades
3. Six of ...
4 Seven of ...

Any ideas?

I came up with a way to solve a conundrum I've been having with a Spanish-English translation c# program I'm working on. The only problem is my class EsVerb has three inner classes. The first of these 3 classes has 5 of its own inner classes. The second of the three has three of its own inner classes, and the final of the three has no inner classes. Keep in mind that these inner classes are all relatively simple with just a few methods each.

What this gives me is a super elegant way to get get the data from the EsVerb class that i need, but 11 total inner classes seems ridiculous in concept. What do you think? Does the elegance of use outweigh the ridiculous class structure?

(Also, the class structure makes sense if you're familiar with concepts of Spanish verbs: the indicative, subjunctive, imperfect, preterite, etc...)

This is hilarious.

List<String> list1 = new ArrayList<String>();
       Collection<String> list2 = new ArrayList<String>();
       
       List<String> list3 = new LinkedList<String>();
       Collection<String> list4 = new LinkedList<String>();
       
       LinkedList<String> list5 = new LinkedList<String>();
       ArrayList<String> list6 = new ArrayList<String>();

What is the difference between them?

>>59909497
Wait a minute, why? Doesn't that syntax just declare box_item to be an iterator? I usually use auto it = vec.begin(), ect, I didn't know they where not equivalent.

>>59910000
You're limited to the lefthand side object type methods, even if there are more specific ones available to the right hand side.

class Animal has a method called "speak".
Dogs and cats have "speak" as well. Dogs have "WagTail" and cats have "Claw"

Animal pet = new Dog();
pet.Speak(); //Works
pet.WagTail(); //Error
Dog dog = new Dog();
dog.Speak(); //Works
dog.WagTail(); //Works

>>59910000
>ArrayList

>>59910058
ohh yes thank you. i get it.

Collection > List > LinkedList - ArrayList

but what is the difference between linkedlist and arraylist And why "List" exists ?

>>59910052
It more or less expands to this

for(auto it = v.cbegin(); it != v.cend(); it++) {
  auto box = *it; // copy each box to for loop body
  // stuff
}

vs

for(auto it = v.cbegin(); it != v.cend(); it++) {
  const auto &box = *it; // just use lvalue references
  // stuff
}

>>59910000
List and Collection are interfaces, ArrayList and LinkedList are classes that implement them but work differently under the hood.

Best book to lean OOP in C++

>>59910728
The best way to do 'OOP' in C++ is to pretend you're writing Go

How can I calculate the depth of a BST in C++ when the function to determine the depth has to return void instead of int? Every google search comes up with this solution:

  
int maxDepth(struct node* node) {
  if (node==NULL) {
    return(0);
  }
  else {
    // compute the depth of each subtree
    int lDepth = maxDepth(node->left);
    int rDepth = maxDepth(node->right);

    // use the larger one
    if (lDepth > rDepth) return(lDepth+1);
    else return(rDepth+1);
  }
}

But for a specific case, I have to have the implement this with this header:

 void maxDepth(node *rootPtr, int &totalDepth, int &currentDepth) 

I'm stuck on the part that implements the recursive calling of the function. I've tried various solutions that compare what the left and right pointers point to, but nothing works. So far my function is

        void determineDepth(node *rootPtr, int &totalDepth, int &currentDepth)
        {
            
            Node *nodePtr = rootPtr;

            if(nodePtr == nullptr)
            {
                totalDepth = 0;
            }
            else
            {
                //nodes exist in the tree
                
            }
        }

Any suggestions? Is there any way I could follow the same guideline as the google suggestions, but not run into the issue of conflicting variable updates?

C is for weak and lesser programmers. They stick to a small and easy language because they know they can never cope up with big languages like C++.

>>59910646
How?

>>59909028
So anyone here can indicate me a good resource to do MFC programs on Windows, because them legacy code won't maintain by itself.

>>59910814
You are given a reference to the integer totalDepth, which means you can modify it in the current scope and it will be changed outside the function. Thus, as you walk down the tree, keep track of the current depth, and at the base case (i.e. a leaf), check to see if the currentDepth > totalDepth, and if so, set totalDepth = currentDepth. Just make sure to initialize totalDepth to 0 (i.e. the case of an empty tree).

Why are 99% of programmers dumb fucking niggers?

An arraylist is a List implementation that uses an array in the background, which changes time complexities compared to a LinkedList, which is a List implementation that uses linked nodes instead of an indexed array.

List is a "generic" class. A list doesn't exist on it's own, behind the scenes it has some kind of data structure. But this way you can use a linkedlist, arraylist, doubly linked list, or fucking-whatever and never think about it because they all have the same method calls to do actions.

Serious question guys - I've discovered I'm decent at programming ( mostly coming from not giving up when I don’t understand something until I figure stuff out ) this process been going only since early this month I've started to try hard and code all sorts of projects for myself, this passion started from a guy releasing a cheat source code for a game ( C++) - started to tweak it, got it work with changes I desired also asked that individual some basic questions - which he promptly answered and also provided help with a lot of programming principles - I think the simple fact he was so nice and helped me a lot triggered some sort of emotional event in my subconscious - since then I just non stop study programming.

I'm basically trying to achieve a decent C++ understanding by the end of the year ( mainly ) but I also want to equally focus C and Assembly.

I've started to reverse engineer games to find engine scripts and other goodies - because right now game hacking is the only domain I experienced and where I can fast and directly implement new knowledge and test it out, I've also started to look into mutliplayer game servers emulation and apply knowledge there as well... thing is I don't want to be a game developer this is just my first baby step, a work around to exercise my new passion and skill.

I need some tips on what to move into next, what sort of stuff should I program to really see some solid improvements?

Don't bother man, as a C++/Java developer you'll feel like Go's developers treat you like a little kid. It was designed so Google could put 100 braindead programmers and one good programmer in a room, and end up with working software.

See https://github.com/ksimka/go-is-not-good

My advice: learn C++ better.

Tested out CycleGAN to see if a neural network can learn to map non nude images to nude images with about ~1500 images in dataset. Results are a failure. CycleGAN sometimes correctly changed the color of clothes to skin color, but the lines of clothes were never removed. Like the authors of CycleGAN said, the network is good at modifying color and texture, but not geometry. Plus, anime images have incredibly high dimension with regard to color (i.e. variety of hair color).

Wish there was a deep learning general in /g/, but there aren't enough people familiar enough with the field on here.

How do I cure my language hipsterism?

Like I can't learn useful normal languages, I find myself only interesting useless hipster languages like Common Lisp or Ada, or hell, even modern Fortran (fucking why??).

I'll never be productive with this bullshit.

>>59909468
Does this only work with STL vectors, or can arrays work as well?

Thanks guys! I appreciate the help. Will check those links out.

Anyone here use rust? What is it primarily used for? I've been looking at trying it out for awhile.

>>59912713
It's very new so it hasn't found its place yet.
Right now it's just a language, if some very well designed libraries for doing this or that come out then maybe Rust will be useful but until then it's just a C++ replacement with a strict compiler.

rate my quine, /g/.
(never done this before, is it even a valid quine?)

>>59912740
What other kinds of visibilities are there?

>>59912740

if(visibility != View.VISIBLE && visibility != View.INVISIBLE

>>59912740
If visibility == Visible, it satisfies the right part of the statement.
If visibility != Visible, it satisfies the left part.
One of those two things will always be true, so the whole statement will always be true.

Retard here. I have a big dataset and am trying to parse the year column to match but their formatting is off sometimes. Example "Mar-12-2005" , "05" and "2005". I'm trying to break it down to just the year.

Should I use regex for this? I typically don't do these types of things so I'm clueless. Just looking to be pointed in the right direction.

/* Write a program to count blanks, tabs and newlines */

#include<stdio.h>

int main() {
    int c, nl, nt, ns;
    nl = 0;
    nt = 0;
    ns = 0;
    while ((c = getchar()) != EOF) {
        if (c == '\n')
            ++nl;
        if (c == '\t')
            ++nt;
        if (c == ' ')
            ++ns;
    }
    printf("Blanks: %d\nTabs: %d\nNewlines: %d\n", ns, nt, nl);
}

it works for new lines but not spaces or tabs

>>59913237

I don't think you should use a regex. You should split it by '-' and the last item will be the year.

Right now I have nothing to show but a fairly inactive Github profile with a few abandoned projects and even less contributions to other people's projects. So it's been a couple of weeks and I couldn't get a single reply.

Is building my own website a good idea? I feel like every other web developer has his own website and his own blog. I'm thinking about starting one. Maybe developing a couple of common websites to display my skills would be a good idea. Any tips?

Because college is an antiquated system. It was originally for someone to receive a well-rounded liberal education and become a scholar. Now it's a catch all for learning anything and everything--no matter how stupid, meaningless, or incompatible with the college system--and as a stepping stone for getting into major sports leagues.

I should've intervened and get help when I got my first F in my second term. Instead I just pulled it through and ended up doing even worse in my third term.

That's up to you and how much work you want to put in. You should be able to put in work on your own and be self motivated if you want to succeed when you go back to college.

>>59913478
>it's effectively trade school for STEMers
Learning STEM via college is stupid. We need actual trade school dedicated to certian sciences. This will not only reduce the cost as you won't have to fund a bunch non-related and stupid bullshit, but it'll also allow graduates to be better prepared for the real world.

>he might really try harder this time
No he won't.

>>59913488
Returning to college will results in two things: depression and a great loss of money.
Not only do you lack motivation, but you also lack discipline when motivation fades. Finally, to survive the world after college, you need to have decent social skills. Networking is as important as getting good grades.

it takes a lot more than 4 years of study to master a stem field. if you're just going to be a koder then you can learn that in a few months, but if you're working on the cutting edge of innovation that doesn't cut it

>>59913542
Yeah I also know some third years who just switched their majors to CS, I wouldn't be the oldest one really.

>>59913550
>Not only do you lack motivation, but you also lack discipline when motivation fades.
True.

Also true about the lack of social skills and networking. After three terms I only have a few acquaintances in university. Thinking about getting a job post-grad frightens me because I have no networking.

>>59913550
I'd love to create a startup for the socially awkward techies for whom networking is like arsenic. One where we would use only the better technologies - no Python or Go! Unfortunately it seems all the VC funding is in CA, and I'm stuck on the other side of the country.

look into IT certifications. a couple respected certifications, having a home page website employers can look at, and knowing python or some other shit with programs up on github can probably get you a decent job in IT. don't take a customer support job or it'd make you kill yourself since you're already mentally ill. don't spend more than 2 years self studying since beyond that you're just fucking around

Any good resources for learning a new language when you're not a total novice? Say I'm totally new to C# but am advanced in C++, Java, Python etc. and would like to avoid the basics of boolean algebra and what a class is.

but i've also heard about people having 4.0s and never getting a job, isn't it all about networking in the US and Canada? or is it better for new grads

Maybe it's not IT i need to move to, but idk what else there is. I just want a nice easy job. I don't need money anymore

>>59913721
It makes sense that you need networking if pretty much everywhere is flooded with mediocre programmers and mediocre jobs working on mediocre code. That may the only way you can get ahead, because if you're good then the interviewer probably won't be smart enough to realize it.

>>59913612
miso soup makes me shit liquid

I don't know what it is. I don't get constant diarrhea or anything, it's just that when I poop at normal times after eating miso, I can shoot a decent pressure jetstream of liquid shit out of my ass to the point where it's similar to pissing.

yeahhhhh don't move to IT.. they'd probably not hire you b/c they'd think you're overqualified. and would be demanding. if you've worked at facebook for 2 years you can put that on your resume and i'd imagine get a shitload of clients for doing freelance work on your own time. making websites and apps and shit. good thing about that i would think is that you can be travelling while you do it, have that be a source of income while you visit grorious nippon or something. i always thought that'd be a cool thing to do. or you can get a wife and start a family in which case you'll want the hedgefund bux

and yes that's x86 (strictly speaking, 16-bit 8086). the xlatb (translate byte) instruction does most of the work here. it sets AL to a value pointed to by [BX+AL] so the hex lookup is quite easy. does 68k have anything similar to that?

it prints an ascii hex representation of itself though, not the exact bytes.
and it does it in a super lazy way by reading itself from memory.

>>59913911
What about folks who graduated a few years ago, and have been working since then?

>>59913928
You'll be fine just don't go for a specialized role like Data Scientist unless that's your specialty

go for the general SWE role

>>59913937
Thanks anon, reassuring to know.

>>59913917
Assembly won't help you much with the Facebook interview. It will help with a hedgefund interview.

Grind algorithms, data structures, etc. and actually learn the material. It's like algebra where you can't memorize the problems but you can learn to solve them.

Okay enough questions about how to get a job at Facebook...

please tell me how to not want to kill myself after working 13+ hours a day

>>59913959
Stop working 13+ hours a day?

>>59909914
My personal preference is for flatter structures rather than deeper structures.
Can use you a table instead or something?

>>59913948
i'll look up the relevant chapters in intro to algorithms, read up on it. what about language specific proficiency? do they want every library memorized if you're in java, and your programs to compile first try etc?

>>59913975
Where should I work? Anons told me to not join the IT industry and stay as a SWE.

What are the best places to work as a SWE where I can basically live the NEET life?

>>59913989
No, but you should know the tradeoffs of a TreeMap vs a HashMap and all that stuffs

>>59913993
i told you already to do freelance while you travel abroad. all you need is your trust t430 thinkpad running debian

you DO have a t430 thinkpad running debian, right?

>>59913993
I've heard that big Java companies are boring, but pay pretty well and you only have to work 9-5.

>>59914014
nope im an apple shill :(

i'll give it a shot for a year and see if i can get any work... the issue is my network isn't great for freelance work

>>59914007
also thanks for the i 'ppreciate it

>>59909713
which is every language basically

>>59914007
Surely it goes beyond the basics?

Please I know nobody uses Delphi anymore but our programming course makes us learn with it.

Is there anybody able to help me with an exercise?

I need to enter a set of numbers for a specific variable, but each set has somehow to be stored undefinitely until I order the program to end it and then it has to list each number of the set.

I cannot use arrays.

>>59914027
dude, you have 2 years under you belt at facebook right? put that on your linkedin, and market yourself. look at places where people look for freelancers and look at places where people post ads for freelancers and you're set. for gods sake don't quit your job until you've already got some infrastructure set up regarding your freelancing tho. this isn't the 1950's, people don't hire someone by calling up their buddies from high school and asking who they know. they go online and see a guy worked for facebook and hire him

>>59914062
Not really. What's the value in memorizing the standard lib? If you know general programming (again, heavily emphasizing algorithms and data structures) you should be able to google 'balanced binary tree java standard library' or something like that.

Obviously as you go up in rank or into a more specialized position, knowing how the JVM works and how to optimize it will become mouch more important.

>>59914080
lmao reminds me of my 3rd year programming course that had us using the professor's own language called cinnameg. the 2-3 questions on stack overflow about cinnameg make me laugh

>>59911803
From your shell prompt:

pydoc range

>>59914096
I meant more being asked to show you're actually able to program stuff, not just being asked "what's the difference between <impl A of common data structure> and <impl B of common data structure>?"

>>59914102
Its not fucking funny.

>>59914080
Why the fuck are they teaching you Delphi?

Maybe they're teaching it so you can't cheat by asking for help online

>>59914112
Oh yeah. You'll be whiteboarding for the majority of the interview. They'll "fizzbuzz" you at the beginning with questions like that or ask you about tradeoffs if you used a nother structure for your implementation. I'm just trying to make sure u get the whole story friend

what is the benefit in GIT allowing someone to change their system time and upload things "in the past"?

why dont they just fix it so it uses their own server time or something

Will it go down badly if I change FizzBuzz to FuckButt?

>>59914126
can't believe you actually took the time to run my code. yeah, it's for 16 bit signed integers, add another couple 0's to 0x8000 if you want it to work on that

>>59912557
Try actually writing a program, or contributing to some project.

If there's nothing you want to write then your hipsterism doesn't matter.
If you have no problem in completing a work then your hipsterism is not impediment.

>useful languages
No language is useful or useless.

People shouldn't use the quote feature without intending to quote someone, it's considered poor form.

These threads should seriously be banned from /g/.
They are filled with too many retards who call random wall scribbles "programming". It's an insult to the board, the field and humanity at large.

>>59914274
You literally did. Right here >>59914243.

>>59914297
Which is the second time this sentence has appeared in this thread, meaning it can easily be a quote (which it is).

>>59914284
They should be banned just for the rampant shitposting.

>>59914274
How much are you being paid to post this bullshit?

>>59914304
You asked who said it. Which you did. I'm sorry this is too complicated for your reddit brain.

>>59913251
its nl++; not ++nl;

Does it matter which university you went to at most software companies?

>>59914312
I'm not even going to explain it to you, because you're so rude

>>59914324
I asked him "who said it", which means I am referring to something he did, not to something I did.

>>59914334
++nl; is correct since he doesn't need the value of nl pre-increment

>>59914339
Explain what? That you have absolutely nothing of value to contribute to this thread, or any other /dpt/ thread? Not once have you posted a single thing related to programming.

>>59914339
You wrote it and then immediately asked who wrote it. It's not fucking complicated.

What is the best anime to watch when:
1) Programming
2) Taking a break from programming

>>59914275
are you guys so insecure that you don't understand what that code even does, despite how short it is, that you can't tell it works for integers that are under 16 bits?

>>59914362
Are you tracking every single post I make? That's the only way you can possibly make the claims you are making without looking retarded.
