namespace and include namespace are two different things and using namespaces is a good thing you authistic fucking nigger faggot.

They are like scope where everything you define under a namespace needs it's name to be called, std:: is a namespace for standard components you use, but using namespace std; omit this, which is bad

Yeah, all you need is just the interpreter. Fuck all the other languages that don't need it and that work without it anywhere, Java works EVERYWHERE, as long as you got the interpreter of course.

If you want efficiency you can acquire it on little things like doing ++i instead i++. using iterators for stl containers, and parallelizing tasks using thrust library or going raw on cuda, namespaces are not relevant for efficiency
>>674483724

the static keyword literally does nothing in C++ if the method or object you're using it with is not a member of a class/struct.

If you don't know what that does, and let me tell you it has nothing to do with efficiency, then you're retarded. Stop programming.

that has absolutely nothing to do with efficiency. both do different things, they are different operators. but in the context of iterating in a for loop, they're literally identical
>>674484135
not to mention horribly insecure to use
>>674484087
If you use shared_ptr everywhere, you might aswell switch to Python, nigger
>>674484039
niggers don't know what C++ is over C, damn you are a fucking retarded monkey
the variable "i" is an instance of a C++ class so i++/++i call the ++ operator on that class, the operator++ for POSTFIX, uses a temp variable to store the data, unlike ++i,
So really, go fucking learn instead of being a retarded faggot

no it doesn't you mongoloid, look at the fucking asm the compiler spits out
the ONLY difference is postfix returns the current value before an increment and prefix returns the value after the increment, it's just the ordering of the asm, neither is "faster" unless it's some specialized operator overload you've implemented that's expensive

go back to pascal
>>674485693
you rarely overload increment and decrement unless you're writing iterators, and my point still stands for built-in types like ints
there is literally no performance of functional difference between these:
>for(int ii=0; ii<count; ii++) { }
and
>>for(int ii=0; ii<count; ++ii) { }
>@echo false
>echo "hello world"
>end
Did I do that right?
>>674485709
EXCEPT THAT IT'S NOT ABOUT PERFORMANCE BUT MORE EFFICIENCY AND BETTER "READABILITY". WHAT'S SO HARD TO GET ABOUT THAT YOU FUCKING DONKEY. YOU STILL STUCK IN THE YEAR 1995? ARE YOU PROGRAMMING ATARI GAMES RIGHT NOW? MEMORY MANAGEMENT MAKES YOU COOL OR SOMETHING? THERE'S NOTHING COOL ABOUT MANAGING EVERY BIT OF FUCKING MEMORY IN A PROGRAM YOU ROTTEN LOBSTER. THE WORLD DOESN'T NEED ASS-BACKWARD PROGRAMMERS LIKE YOU AND FRANKLY THE INDUSTRY ITSELF WOULD BE A BETTER PLACE IF YOU JUST JUMPED OFF A BRIDGE WITH A N ATARI CONTROLLER CABLE TIED AROUND YOUR PENCIL NECK.
>>674485959
I agree with built-in, the compiler will optimize.
But I mean for your defined objects and since I program focused on iterators / templates because of my work field it does difference on performance.
>>674485709
you are exactly the kind of programmer I would never hire or want to work with. you have this massive ego that you write perfect code with no errors, and shouldn't use smart pointers, or things like implicit sharing, and any "new" idea from the last 20 years that wasn't used in C in the 80's

>>674485539
Yes, even in C++. I read the spec for breakfast, nigger.

>>674479286
I code both, and it really depends, but it definitely has a lot more applications than C++.
Nobody here seems to care about fast and easy coding. If you guys think of creating efficient algorithms, than you should learn discrete mathematics and logic. Programming is already slow as it is, don't make your lifea shitier.

Yeah apparently I can code Java on 3 billion devices, including my coffee maker, my toaster, and my vibrating dildo. Last night I wrote an application for my dildo that made it vibrate twice as hard which made me cum four times in a row. But for that work I had to install an interpreter up my ass so Java could work because if I hadn't the compiler told me to go fuck myself.
>>674486385
you didn't even read your own fucking reference you fucking retard
>The static specifier is only allowed in the declarations of objects

>>674486518
that's why theres computer science and information systems, the later is for lazy dumb programmers
>>674486218
No. What I'm saying is that if one advocates using reference-counted pointers everywhere (read the OP), one might want to reconsider language choice.
I'm not advocating not using shared_ptr. I'm constantly using C++11 and some 14 features, actually.
>>674486156
>>674486156
Exactly, and that's why there's nothing cool about still writing in C++. You cunt are making my point for me!
>>674486891

> The static specifier is only allowed in the declarations of objects (...), declarations of functions (...), and declarations of anonymous unions.
And further down:
> Any of the following names declared at namespace scope have internal linkage
variables, functions, or function templates declared static
Now please do yourself a favor and stop believing you know C++. You clearly don't.
>>674487364
Well, programming is a really extensive field, you have commercial and it-solutions-blabla where performance isn't really an issue and you have scientific research fields where every O(log n) optimization does matter a lot.
You will find very difficult to do one thing while on a course that does not focus on that.

>>674487148
If "good coding practices" are basically "avoid language's features at all cost and use library X everywhere instead", then yes, that language has failed.
do you guys know how to use && ? which cases I want to use it?
>>674487369
>>674487369
why?
>>674487591
it's unnecessary when used in anonymous namespaces, it will already have internal linkage, there's no way the linker will use that reference anywhere else in your code even if they're named the same
and a static non-member function in C++ means absolutely nothing

hello world. i used to fuck all ur moms.
she'd come over sometimes while her boyfriend was away after school.

once the door would close she'd almost instantly get naked. most times she'd put on her favorite song and start sucking. then she would cry. her tears and makeup would drip down her face onto my dick. its surprising how cold tears are. eventually i finally asked her what was wrong. in between licks she told me that her favorite song was also her bfs favorite song. so even though she loved hearing it and it totally got her pussy wet, it also made her think about the fact that she was cheating on her boyfriend. i dont think i ever came harder down somebodies throat then right after she told me that. she was beautiful. we dont hang out anymore. wanna get lunch?

"BUT USE PYTHON ITS EASIER" YEAH USE A LANGUAGE THAT TOOK THREE POPULAR SYNTAXES, THREW THEM IN A BLENDER, TAKE THAT OUTPUT AND GIVE IT TO A MONKEY TO WIPE ITS ASS WITH IT THEN GIVE THE DIRTY ASS SMELLING THING THE NAME OF A FUCKING SNAKE. YEAH ABSOLUTELY LET ME GO USE IT RIGHT NOW. EXCEPT I WON'T BECAUSE ANYONE WITH A BRAIN THE SIZE OF A MOLECULE CAN UNDERSTAND THE BASICS OF ALL THESE "HARD" LANGUAGES THAT YOU COMPLAIN ARE "SO HARD TO USE". GO PROGRAM IN VISUAL BASIC OR SOMETHING STOP WASTING EVERYBODY'S TIME YOU CHILD OF THE HIGH KING OF MONKEY VILLAGE.
>>674488285
DO NOT USE RAW POINTERS, EVER. USE vector, shared_ptr, auto_ptr (oh no, that was a mistake, better unique_ptr). Yeah right.
DO NOT USE FUNCTIONS, USE FUNCTORS.
>>674487705
Yes. For being such an extensive field there is not much gain in trying to master it all. Especially in the short term. I once helped the physics department in a simulation of atomic clouds (though it soind awesome, i didn't do much besides looking) and yes, the care they have to optimize everything is amazing
>>674488301
don't do that, there's no reason to unless you're going to be a Linux kernel dev

>>674488670
Do you feel better now? Was it really worth it?
>>674488670
I think you're a student and have never worked on a real-world large C++ code-base.
>>674488562
Like I said, it depends on the work field you are aiming, Information Systems (at least in my country) focuses on business and techonology in general, they don't care why heapsort is better than bubblesort or how I'm able to span threads efficiently.
They focus on business solutions and such, the problem is when people with this knowledge think coding is just what they saw on the course and don't know optimization exists and think they are worthless and too hard to understand for example, to do a good program without memory leaks one must understand how the memory works internally
>>674488691
I don't even understand what you're arguing anymore. smart pointers are good, and you should use them everywhere. you should always use objects to manage resources unless you have a good fucking reason not to
>>674488738
yes, at these places we want to use ++i instead i++ for your custom objects because every little efficiency matters.
I'm currently working with fluid simulation, like air or blood, you spam literally millions of threads, if you don't code optimizing everything your pc will explode
Computers and programming have a wide range of applications, such as counting money for business men, and various digital dancing simulations.
>>674489134
> smart pointers are good, and you should use them everywhere
> use them everywhere
> everywhere
This is exactly what I'm arguing against. Use them where it makes sense. Or, if you literally use them everywhere, embrace it and go for a language which makes this behaviour a default, not tacked on.
> you should always use objects
OOP is not the magic solution to everything that you should always use.
>>674489376
right, but don't mindlessly do micro-optimizations, especially if it makes the code harder to read and maintain. you should only ever be doing it after it all actually works, and you've profiled it to prove there's a real performance hit that matters. then if you must. optimize where you need to, and add comments explaining why this horrible block of code is written the way it is
>>674489431
hey this is fun!
>>674489376
I know a fair amount of math but have never coded anything in my life. I fear I will get bored doing babby exercises if I choose the wrong language to learn first. Any suggestions for a first one? Preferably one that let's me start using all of the cool math I've learned early on
>>674489548
>This is exactly what I'm arguing against. Use them where it makes sense. Or, if you literally use them everywhere, embrace it and go for a language which makes this behaviour a default, not tacked on.
if you're using C++, you probably have a good reason for it, why would you jump ship to something much slower, or ill-fitting just because you're using smart pointers?
besides your personal hangups against smart pointers, why would you NOT happily use them everywhere?
>>674489858
practically any language will let you do math, what do you actually want to learn or accomplish?
if you want to just do the math with minimal coding you could use something like NumPy in Python that's made for things like that
>>674489858
You are absolutely right about being bored, yet, if you are a good mathematician you SHOULD definitely give it a try. After the first steps it starts to actually be fun, that is if you are only learning
>>674489858
Math? you could aim for matlab or octave, there are lots of nice stuff you can do with them, python too, they have a math and linear algebra library that's awesome, but C++ is your goal for performance and math, but it's a harder language for beginners, learn the basics , play with python and C for example and later on go to C++. Don't rush things
>>674489713
Yes, only where it matters and for sure I maintain my code to be as readable to the next guy as it is to me, comment everything that's worth and make things simpler like using "auto" instead the huge iterator type name
>>674490064
Only good reasons for C++ are, imo:
1. performance. shared_ptr ruin performance
2. legacy. you're fucked anyways
Any other reasons I'm missing?

if smart pointers ruins your performance, either you're doing it wrong, or have a specific use case where raw pointers actually make a difference, in which case you have to make damn sure you're being careful with allocations and deletions
in 99.9999% of cases, the small overhead of the reference counting more than makes up for the performance hit you likely will never notice without profiling
>>674490471
What are you talking about, this thread is awesome! Lot of people, different levels, and pretty much getting along

>>674491081
the code is from OP's image ...
>>674490857
agree, and usually you can go around using variable/object references
>>674485395
Using micro optimizations as a standard for all of the coding is a good practice though.

Not sure I'd call myself a good mathematician, but I really enjoy it and am motivated to learn more. That said CS is also really interesting to me, I'm just CA pleb when it comes to tech. I originally studied biology but ended up hating working in a lab. Now I'm wrapping up a math major and stats minor. I will be taking an introductory cs course in the fall for my major, but wanted to learn a language over the summer
>>674490471
Don't forget std:: or the namespace. Or main's return type. Scrub.
>>674491163
You see? Different levels! If you have dayjobs and that kindo of shit, i would try to learn from tge online course CS50. It isn't actually c++ but you will learn a lot about coding

This whole post reads exactly like what people arguing for higher-level languages write. I think I'm done here, if you still don't see it, whatever. Good night anon.
>>674491239
references aren't going to help when you need to keep track of large numbers of heap-created objects, and use them throughout your codebase. In cases like this you'll probably have some kind of factory doling out these objects to be used, and they need to be cleaned up when they aren't needed anymore
doing things like this without smart pointers is extremely error-prone and difficult. you'll either end up leaking resources because your manual reference counting has flaws, or the other worst case, you end up double-deleting an object and/or referencing an invalid object that was deleted elsewhere
>>674490413
Negligible difference if there even is one really.
It's miles better to have managed pointers, raw pointers are just asking for a disaster, especially in larger programs.
For smaller things like coursework for a class at uni it's not too bad, but for everything else some kind of smart pointer is essential. (Especially if needed in the initialisation list in a constructor.)
>>674491291
lolno
writing "optimized" code from the outset is a waste of time, and just makes the codebase harder to maintain. you optimize when you know you have an issue, not before
>>674491795
Yes, at least shared_ptr avoids dangling pointers which is another nasty thing to deal if you lost track of it.
Also I already see some plp don't using pointers because "muh object will be deleted when its out of scope, that's what destructors are for, so I just let them be untill they reach the scope" so yeah...
>>674491418
Than you are the perfect subject. I think your skill set is quite enough to take advantage of coding, as the other anon said it c and python are exelent choices, octave is freat too. One shouldn't exclude the other
>>674491746
you make it seem like there's no valid reason to use C++, which couldn't be further from the truth
>hurr durr you should only use .NET or Java unless you're running on a super computing cluster
>>674491746
If you can be sure you've not fucked up, lower level's are fine.
Pointers have the capacity to be so dangerous, smart pointers are worth the overhead like every single time. Coders are only human remember.

>>674490350
Thanks I was thinking about pursuing c over the summer. Been on /vr/ quite a bit lately and want to get into rom hacking. To my understanding, c is sort of like a portable assembly, so learning it first will set me up pretty well for that. I've also dabbled with bin / hex conversions and found that enjoyable, especially given some of the theorems I learned in algebraic structures. But like I said a pleb when it comes to actual tech and applying this sort of stuff
>>674491990
It's worth keeping an eye on things, but yeah. Get it working first. Then fix as required.
>>674492547
Once you've done C, you can try C++ too, it builds really well off it. Great language too, it's quite light too, it's not like Java which has a million things.
>>674477864
I did, then moved to C++. Java's only good to have written on a CV.
>>674492547
if rom hacking and low level stuff is your goal (and its awesome)stick with C untill you understands the memory and can implement more complex data structures like AVL-tree and a graph.
I think if you do that in less than 6 months you will be a good programmer..
If you want that I would like to suggest you some topics, learn the computer memory system, and the operational system aswell, virtual memory and pagination, understand how the memory works, what's under the hood, and you will rom hack everything, trust me on this one.

you've never coded in your life, have you?
go write some non-trivial application to run on WIndows. Now go compile it on Linux and look at how many build errors you get. Unless you're using a framework specifically designed for it like Qt, you're going to have all kinds of defines and conditional includes to get things working on more than one platform

Well sure, if you use a low level language like C++ to squeeze every bit of performance out of it you can. But you'd probably be developing it for nix because winblows/osx sucks. So your argument is pretty shit.
The fact that you're a Java fanboy indicates you've either haven't finished comp Sci or you haven't left the darkness of enterprise Java land. There are less terse, more portable and more performant languages out there that don't require the JVM.
That and docker kind of blows away the shitty Java argument of portability

When he told you about ++i you were able to not laugh or cry?

More references then:
1)A good OS book is Operating System Concepts (2012) by Silberschatz, Galvin and Gagne. Also known as the "dinosaur book," due to the irrelevant dinosaurs gracing the covers of the book's many editions, this is a great introduction to OS design.
2)For Architecture / how the processor and CPU works (you will learn basic MIPS assembly here) so, get a copy of Hennessy and Patterson, a classic text, which uses MIPS throughout for its examples
Keep in mind I pointed 2 books for low level stuff, but from what you told me you like these so I hope they will help you, I love these 2 books so I hope they will turn to be useful for you :-)

learn good coding practices, like smart pointers, forward declarations, pImpl (where appropriate), using const wherever possible, learning proper inheritance. you can spend years with C++ and still not know all the ins and outs of the language
>>674495548
Hey C++ has its place, far sight better than Java. Hell it has better language specs than Java which is just fucking appalling for Oracle.
I can see it shrinking in importance though. As hardware gets better, the need for programmer memory management becomes less of a thing. And without memory management, you might as well use dot net or Golang. Orsomething functional because functional languages are fucking awesome
>>674477142
C++ is detritus.

thank you kind sir, all the best.
>>674496736
well in my case, we need to interface with certain libraries, and hardware, and it would be a lot harder to do with a lot of managed languages. and in our case, performance is kind of a big deal because things need to happen near real-time, dealing with streamed data that can't really fall behind
>>674497090
Now just put it in an infinite loop
>>674496736
I doubt C++ will stop being highly used as hardware gets better so the need for even more powerful programs especially on simulations and gaming.
Also GPU is on high demand nowadays and you can't use java or some shitty tier to program on GPU.
The need for C/C++ will always be there, the problem is, to be good on C/C++ take years, so the jobs are not just "code monkeys" like a 5 month experienced java guy has
