I think you should kill yourself, mate.

I'm triggered.
just go away, im trying to code in html.

Is C++ a difficult language to throw myself after just introductory classes (with java)?
should I practice fundamentals with C++ first then move on to different languages or do the reverse?

>>57319242
You shouldn't use C++ for any purpose.

Is one of these statements better than the other? Seems like in the first one the program has to computes the same function 3 times. The second one computes the function only once but has to use some memory to store that value.

Because its best to have a professor and university learning environment when learning more complex shit like Data Structures and Algorithms.

Sure any monkey can learn to fucking code on their own, but when it comes to DS&A it's a little more than just knowing how to use a fucking API and more of thinking like a computer scientist.

Also you'll never get hired by any big company if you don't have extensive knowledge of algorithms and how to approach problems efficiently.

All that stuff can be learned, and you certainly don't need to learn it from an out of touch professor in an algorithms and data structures class that is only taught once every other semester.

My CS program was so shit the data structures course was only once a year, and since it was the only DS course offered on a predictable basis, people from other colleges would enroll just for this once class and it made it difficult for local students to get in and to make it worse, this was THE capstone course to transfer.

I'm so glad I dropped out.

>>57320185
>out of touch professor

yeah if you go to a shit university yeah but it's well worth having an environment where you solve problems by deadlines and receive criticism (grades) outside of the job world. Also, to you know, use the professor as a resource to help solve any issues you are having with your algorithm.

Okay, double checking the documentation revealed I wasn't using the correct delete function but I don't think that's quite what I'm looking for.
My thing has a single PNG memory chunk that it uses to just redraw the new images onto, and then passes a copy of that memory chunk to a thread to write it as an actual PNG file - EXCEPT until the program ends or the structure is properly deleted, all the memory chunks i want to save to actual PNG's remain despite a) passing a copy and not a reference and b) the threads themselves ending.
My assumption was that since I passed by copy, all those memory chunks should be deleted once the program ends, while the main image is constantly just rewritten over until it gets deleted.
The memory chunks were originally malloc'd but i thought that if they were then copied/passed into a thread and the thread ended, the memory chunk would be deleted there?

Because you don't know jack shit about CS when you study math. A math guy would have a real big advantage when studying CS, but he would still have to the differnt contetnts.

Think about it like that:
There are at leat 14 different areas in Math, and a guy who is eldergod tier in statistics (knowing his Triple Integrals like the back of his hand) doesn't mean he knows topology. Just because someone is great in Differential geometry doesn't mean he knows anything about Combinatorics.

Of course there's sometimes overlap, but it's more about the "tools" they use. The actual important results are not always related so you wont find a math guy who is great in every part of math.


tl;dr: Theory and practice are theoretically the same, but not practically.

Why shouldn't I store all my data in bytes and just remember the indices?
I mean, all those record structures and shit only add unnecessary overhead, right?

Guys, I am confused.

I am reading a Java book right now, and it outright told me there are no pointers in Java.

p = new Object();

>Why shouldn't I store all my data in bytes and just remember the indices?
That's what the compiler is doing for you.
>I mean, all those record structures and shit only add unnecessary overhead, right?
No. They do exactly that, except that they are careful about alignment and padding to keep things fast.

If you are really concerned about things like that, which you shouldn't unless you have a really good reason, check the assembly your compiler generates.

>>57322439
To answer my own question, it appears it does.

References are basically restricted pointers. You can't do pointer arithmetic on them for example.

>>57322454
It makes me anxious to know that the compiler is doing something behind my back that I don't understand.

>>57322542
Look at the assembly and try to map it to your code to get a feeling how your C code runs on your machine.
Maybe write a few simple programs in assembly to get a feel for it.
Implementing linked lists in assembly is fun.

hey guyse, if I do

import static java.lang.Math.max;

max()
or
Math.max()

Pretty sure you would just do

So you could just use max() as-is.

Kys faggot.

Programming newfag here; I'm creating a class in C# and I understand what it means to write/have traditional getters/setters, but I'm just slightly stuck with changing habits of naming methods when using { get; set; }.

So let's say I have

private string firstName, lastName;
private int grade;

Normally I'd have a getter that looked like

public String getFirst()
{
    return firstName;
}

and a setter,

setFirst()

.

However, I can't have a method

public String firstName { get; set; }

since it would conflict with the instance variable I have. Do I just go scrounging a thesaurus for synonyms of "modification" at this point? Or is it common to abuse capital letters and do something like "FirstName" for the method name?

>>57323364
>what it means to write/have traditional getters/setters
Nothing. It's just a meme.

Although, keep in mind that you can do whatever you want. These are just general guidelines that most people follow most of the time.

its not really abuse, PascalCase is typically used for properties, with private fields using camelCase or a preceding underscore (_firstName)

Exercise 1: Write a C++ program to print the following lines:
You are 10 years old.
You are too young to play the game.

Solution:

#include <cstdlib>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
    int age;
    age=10;
    cout<<" You are "<<age<<" years old.\n";
    cout<<" You are too young to play the game.\n";
    system("PAUSE");
    return EXIT_SUCCESS;

This. Static typing is horrendous

>>57323928
More of a guarantee on what can go into something you've created.

More of a guarantee on what a function is looking for that someone else created.

Less chance of runtime errors.

Less chance of unexpected results due to a data type that's technically compatible, but not designed for.

In reality, it actually allows you to write LESS boilerplate because you don't have to go around type-checking everything.

tl;dr: Dynamic typing is fine for scripting and small solo projects. Static typing is better for an actual program involving a large project and multiple team members.

So far, we've been speaking in anecdotes. I've got some years under my belt, with quite a bit of experience working with teams to back up my opinions.

Unfortunately, the only studies done on such things are dubious at best. I do think that there are some good facts to go off of though.

Take any 100 projects at random that have at least 40 team members. I would be surprised if at least 85% of those projects weren't done in static-by-default languages.

Now, I'm going on a tangent here, but I believe that much of the benefit of dynamic typing and scripting in general stems from brevity. Luckily, languages like C# have come a long way to allow you to write exactly how you want.

Static by default, but dynamic if you want.
Safe and managed by default, unsafe if you want.
Verbose or with brevity, depending on your preference.

Pic related is a good example for how Java has managed to step up the comfy game over time.

Also, you may dismiss those arguments as "dull", but they are extremely important to the human-time aspect of a project. If any of my 5 claims are correct, that means less developer effort, which is a good thing.

If you're more comfortable with Python, then yes, stick with Python and Django. Javascript is just more ubiquitous through the industry, but if you know the basic flow of how things will go from working with Python and Django, it shouldn't be too difficult to get into both understanding Javascript syntactically and in terms of development flow (p.s.

Most poos i work with can't explain why they do stuff. they are literally copy paste stack overflow code monkeys.

I need a really fast 2 way map where none of the elements in the set overlap. So think of a mapping of every letter to a number. Where you search for the letter and it returns the number or you search for the number and it returns the letter.
Whats the best way to do this. I usually just make to arrays that are the same length but I could also just make a struct that has the letter and number and put those into an array. Im just worried that the compiler will add setup stuff for the struct. Especially since Im working in java and theyll have to be classes and Im not sure if JIT will make it slower to construct the array of classes vs the arrays Id initialize.

Microsoft does not ship good programs, and this is not even a "Linux vs. Windows" argument there. Their software is just crap. There's nothing to it. It might be popular, and it might be used by millions of people, but it does not change the fact that there are lots of people in MS that don't know how to program properly.

Examples:
Have you ever seen the DirectX documentation? XAudio2? Their kernel interface? Where is my fucking VirtualReAlloc()? Why do you have to store everything in a registry, or in XML files? What's with Microsoft Office not adhering their own standards?

I disagree, but it's hit or miss.

Active Directory, SQL Server, SSRS, Power BI, the entirety of Azure, Data Factory, .NET and its ecosystem, the Cognitive API services... all fantastic things, and I could probably name more that I've used to success.

The code might be spaghetti, but its works for them.

When you compare some of these things to offerings by IBM or AWS, or even other vendors like Informatica and Tableau, they're simply much nicer to work with because they all work together so nicely.

And that starts with the simple fact that most businesses use Windows, Active Directory, and Exchange, or at the very least, Office 365.

>>57324869
>Visual Studio
I strongly disagree. Managing project configurations is such a pain that I rather just open the project file in a text editor and do it by hand. Fucking auto-format formats my code even though I explicitly told it NOT to do that, it takes eons to start up, and Intellisense is mostly useless to me.

>Microsoft Servers are good.
What explicitly? IIS could only compete when they put parts of it into the kernel (which says a lot about their context switching paradigms - IOW they didn't give a fuck until it was too late, and then they just tried to cover it up. And when there's a bug in the implementation - AND WE HAD SUCH A BUG in April 2015 - then you can completely own the kernel). I wouldn't call that "good".

>I don't want breaks on my cars. What do they exactly do?

Static (good static) lets the compiler catch problems like when you are sending the word "clown" to a function that calculates exponential values and expect only int's.

You have 2 options teach good practice and to use the 3 chars int before your variable or write 30 lines of python code to catch this crap and deal with it.

Try writing this useless shit in every function you ever write and you will beg for a simple build in system where you can only use 3 chars like int to save hours of writing code.

The other option is to be a LOL-python baby and write code that will explode and fail by the slightest error, however you saved the use of 3 chars.

>>57324919
>The code might be spaghetti, but its works for them.
Well, there you have it.

You are using them not because it's done correctly, with a nice layer on top of that to make it possible for non-autistic people to actually use it while still exporting the underlying interface for people who know what they are doing and want to get the last bit of performance out of their configuration.

No, they just hid their shit behind enough comfort so that you don't notice it immediately. That's one flaw that free software has, too - once you poke a bit into it it keeps extruding shit as if it was oil in the desert.

Right. I did it again.
From the pro/g/ramming challenges, the numbers to text thing.
New and (debatably) improved: http://pastebin.com/bHWhYLkU
Oldie: http://pastebin.com/GVdL30B1
New over old: now uses arrays of strings over switches; everything is maths-based.
Old over new: old could do any positive integer (maximum string size permitting), making use of the thousands list beyond billion (up to quadragintillion and using gorillion beyond that); was based on comparing characters of a string so, as I didn't include anything to filter out letters, inputting "Litt1e" gives you "L hundred and i-t thousand t hundred and e-teen".
Also, I couldn't think up a better way of making the thousands list than that mess at the bottom.

To C++ from Java? No: that's what I did.
They're both based on C so there's plenty you'll feel at home with.

Ooh, that reminds me; I made this not that long ago: http://pastebin.com/3Ez6vjzz

Clojure got nothing going for it.

The whole concept of "static typing" comes from an area when computers where slow and programmer where hardware nerds. Nowadays there is no need for langauges being "stupid" anymore.

When a langauge like Java overflows, a modern language like Ruby realizes that and automatically casts it to big integer. You just don't overflow anymore.

Now ask yourself, do you really really want an exception if the number hits an (arbitrary) size? No, you want shit working. The less unnecessary informations, the more productivity and lesser bugs.

There's nothing wrong with using namespaces for short projects, aka all C projects.

>>>/qa/

Doing a uni assignment, the night before it's due, as per usual.
I need to list 3 games that were made in Unreal Engine, then say whether or not that was a correct decision, to develop on Unreal, compared to other engines.
I've only used Unreal for a very small amount of time in this unit. Last year I taught myself Unity (did a shitty sidescroller).

The only thing I can say about Unreal, is that it seems to be more accessible to people who can't code for shit (with the Blueprints thing).
Though it is, according to some random guys online, more optimized that Unity.

But it feels weird to take a game, and then say, "this was a horrible choice". If I used Unreal AND a different engine for a few years, I might be able to make that call. But all I've done is import models, play around with input, and do some lighting. Fuck all really.

Opinions /g/?
Feel free to point me to a thread focused on Game Engines, if they exist.
I normally just talk in /dpt/ is all
