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

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"

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?

>>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

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?

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

>>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

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

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

>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?

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

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

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

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?

#include <iostream>

main()
{
cout<<"Fuck u op"<<endl;
}

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
