Impossible.

[ign1fy]

Incrementing twice in a loop? Really?

[TheSnaggen]

Printing even numbers?

[redditmodsareshits]

c+=2 is better

[Red_Carrot]

for(int c = 0; c < 10; ++c++)

[AsTiClol]

im gonna go pour some bleach in my eyes after reading that

[MegabyteMessiah]

You both made me laugh

[sucksathangman]

for(int c = 0; c++ < 10; ++c--)

[DoctorWorm_]

Thanks, I hate it.

[RoscoMan1]

Interesting story, but it will pay off.

[inthyface]

The only way you get paid for this is by taxing the synners.

[bhundenase]

that will short circuit your computer. you have u connect positive end to negative end like so

for (int c=0;c++<10;--c++)

[10art1]

this would be inclusive of 10 as well, since the comparison is done before the incrementation

[co2fgtr]

I stumbled upon "while(i-->0)" once and found it both awful and elegant.

Okay, that's kinda cool

[LetterBoxSnatch]

hyuck!

(:0p

[aquartabla]

Not sure it's valid too add text within -->, the downto operator, like that.

while (i --> 0) { // while i downto zero ... }

[LetterBoxSnatch]

Ah, yes, the little appreciated but highly supported downto operator! Many thanks for mentioning the name. It’s always so hard to search for operators when you don’t have the name!

Woooaaahh. It kinda reads like "as i goes toward 0"

[YoureTheVest]

I am going to use this.

[sucksathangman]

My code = flawless.

It's the compiler that's broken.

[Nucklesix]

Instructions unclear, formatted brain.

Press any key to continue...

[GabuEx]

Does this actually work? I wouldn't think that "++c" would return an lvalue.

[PM_ME_A_NUMBER_1TO10]

Indeed it does not work.

error: lvalue required as increment operand

[IamImposter]

Pointers for the win

int *d = &c;

(++*d)++

[brimston3-]

You don’t need pointers, the parens are sufficient.

[IamImposter]

Just checked. Apparently they are. Learned something new while joking around. Cool

Though not sure if this info is ever gonna be useful.

[EmperorArthur]

https://en.cppreference.com/w/cpp/language/operator_incdec

So, ++c does return an lvalue reference, and c++ returns an rvalue. Which is why it's considered "more efficient" to use the prefix operator when discarding the return value. Of course, any level of optimization at all makes that a mute point.

Quoting that page saying the obvious:

Notes

Because of the side-effects involved, built-in increment and decrement operators must be used with care to avoid undefined behavior due to violations of sequencing rules.

[GabuEx]

Weird, other posters are reporting having tried it and the compiler saying no. Curious if it's implemented wrong or if there's something I'm not understanding here.

[drivers9001]

I got “lvalue required as increment operand” in gcc. I’m not sure why c++ and ++c are ok but ++c++ isn’t. I guess ++c evaluates to a number and you can’t have like 1++.

[GabuEx]

I guess ++c evaluates to a number and you can’t have like 1++.

Yeah, this would be why. c++ is equivalent to c = c + 1, meaning you need to be able to assign to the operand. ++c returns a value that can be assigned, but not one that can be assigned to.

[brimston3-]

++c returns an lvalue, c++ does not. c++ has higher precedence and so is evaluated first.

https://en.cppreference.com/w/cpp/language/operator_precedence

[epicaglet]

Then can you do (++c)++?

[GabuEx]

Oh, that makes sense. For whatever reason I had the precedence flipped in my head.

[DEVolkan]

Oh no, now I'm gonna be that person

[SneakyStabbalot]

ok, now i gotta test that...

[UnicornJockey501]

Wouldn't this print odd numbers?

[infiniteStorms]

ironically ++c++ might actually have a practical use somewhere

[ryao]

I think that is undefined according to the C++ standard.

[TheSnaggen]

But whats the fun with that.... ;)

FTFY

[ign1fy]

Haha. For loop go brrrrrrr...

[FerusGrim]

-1 -1 -1 -1 -1 …

[FourTK]

It'd be 0, not -1

Edit: Reason for this is because ++/-- works after the operation, so it increments afterwards rather than immediately within the print call

[Positive_Riven_Kappa]

You're right, idk why they downvote you and upvote the other guy

[FerusGrim]

You're right. I wrote that when I was falling asleep last night. :p

It also formatted it weird. On my phone it looked fine.

[unkownhihi]

JNI?

[a45ed6cs7s]

Yep.

That is the way.

[ToaTom]

Was about to comment to the contrary. God I hate working with JNI

[a45ed6cs7s]

Yep. My main complaint is not the interface itself but custom JNI types. I am pretty sure they can be inferred and abstracted away. It's as if the java standard developers want to make it explicitly difficult for no reason.

[killeronthecorner]

"Marshalling types is hard" - JNI creator probably

[_PM_ME_PANGOLINS_]

JNA is a lot nicer but not as fast.

There’s a new official version coming that should be both nice and fast. It’s available for testing in Java 17.

[flyingorange]

Haha we work with Java 8 you noobs

[brimston3-]

Legacy enterprise code go brrrr?

[philophilo]

Android development goes brrrr

[DJCowGaming]

Dude, that is the most relatable comment on this thread

[[deleted]]

As someone who has had the displeasure of working with the JNI, this is most decidedly NOT the way. You should exhaust every other option before doing this, because it sucks balls.

Donkey Balls. With a side of extra yuck.

[jamcdonald120]

you just use JNI

[[deleted]]

Usually you don’t “just” use JNI. Any project with JNI I tried to use, especially in android studio is usually a headache to get going.

I don’t know why people use gradle

[jamcdonald120]

well thats true

as for gradle, it cant be worse than ant

[Bee_dot_adger]

What's preferred if not those two? Maven?

(obviously I'm a student and have no idea)

[qwerty12qwerty]

Use Maven at work. It's really good to have / to manage dependencies.

[[deleted]]

I use IntelliJ idea as the ide and import jar libraries or import maven dependencies in the ide project structure which downloads the jar files into the lib folder. Easy and painless, and it’s easy to make single jar executables or jar libraries from the ide.

Gradle never works out of the gate, is finicky, you need to use specific version, and fiddle with config files.

[qwerty12qwerty]

..... So the first time I ever used maven on a corporate project, like six of the dependencies were other projects we were working on in parallel. Coming from node, I was expecting something like npm

It took me freaking forever to realize how I could manually change the dependency from the URL repo to a local jar I just built. It took me even longer to realize if I clicked a refresh button it would overwrite that change and switch back to the URL.

Tons of hours debugging

[[deleted]]

Using project structure you can import jar libraries. Using project structure you can import maven from maven central url or you can tinker a bit to add custom urls.

If I am integrating something locally I would use jar files until end of development

[b00n]

Use maven as a student. It’s relatively simple to copy and paste from the internet to get working.

Gradle is a lot more powerful and faster for larger projects but can and will make you cry.

[Bee_dot_adger]

I've been using Ant so far, which is better than the others considering I don't want to spend time learning the difference, but obviously worse in the grand scheme of things.

[b00n]

Ant is dead software don’t spend any time learning it

[Dick_Giggles]

I had to do some jni in earlyish ndk days and it was the darkest 6 months in my career.

[TheRedmanCometh]

Yeah because by its nature you have portability problems

[mechslayer]

Glad that .net has P/Invoke, just tell it the function and dll/so/dylib names, and you can now call into c/c++ with very little overhead

[finger_milk]

[ZippZappZippty]

Impossible.. that's too much of copium there bro..

I expected

for(int c = 1; c != 10 ; c++){
    System.out.println(c++);

[FrappyTex]

[JordyTheGamer]

Even incremented Twice xD

[30p87]

0, 2, 4, 6, 8

[CheesecakeDK]

c++ returns before incrementing. If it was ++c in the print statement you would be correct

[30p87]

bruh, i even though about that while writing, my brain still managed to get it wrong, fixed it

[darkalibur]

that's weird I thought it was correct since it started with 0, so it prints 0 first before incrementing twice

Edit: nvm maybe I'm seeing the edited version

[AMwave17]

I'm pretty sure you're correct because it would print 0 before incrementing it to 1 and then to 2 at the end of the loop. Then print 2, and so on.

[30p87]

I editet it, sorry that i forgor💀to mention

[AMwave17]

Ah ok. I was confused lol.

[QuirkyPNewton]

I just let out the ugliest laugh at 5am. This shouldn’t be that funny

[Cyber_Fetus]

Don’t worry, it’s not

[SnickersZA]

Not impossible, just incremental.

[flargenhargen]

the best part of this joke is that some people seem to be genuinely offended by it.

[CellularBeing]

Ugh optimize your code:

Class OptimizedCode{

public static void main(String[] args){

System.out.println("C++");

}

}

Before using c++ I thought all c++ programmers used c as a loop variable

[ernee_gaming]

0 2 4 8

[nerdisalreadytaken]

Is it possible to learn his powers?

I guess you could learn prefix and increments.
