and doing so before coding

Oh I meant sometimes people word things oddly

its probably worded in a mathematical way

Sometimes yeah

which takes some getting used to

And then sometimes itll write a big long story and then at the end be like oh yeah btw just multiply 2 numbers together that's all I want you to do

😵

lol that goes back to understanding it conceptually

a white board is your friend

Also there is an app on the phone I've been using and there are tests you can make and let other people take

Like 50% of the problems are knowing what x++ does compared to ++x

so entry level stuff

lookin into algorithm problems

Yeah but at the same time, whoever writes ++x is annoying

?

no

i prefer ++x if i have the option

even tho the compilier will optimize it probably

🤣

Wait what do you mean? Does compiler optimize that? They do 2 different things

If you don't keep the result it won't matter at all.

Nothing to optimize.

they effectively do the same thing, just what they return is different. ++x is one less instruction. a compiler may choose to take the statement x++ and optimize it to ++x if it wants.

Or rather, the compiler will know not to bother with the result, but the order in which in does the operation and keeps the result won't matter because it will be discarding the result.

Well depending how you use it

if it makes a difference in performance, then the compiler will often take care of it bascically

it might still matter on smaller embedded devices tho

Well I mean like if you do x+=++i that'll give you a different number that x+=i++

Yes, but also, don't do that.

if youre doing something like:
```
arr[i++] = x;
arr[++i] = x;
```
then yes, but thats because they return different things

but after the statement "i" will still be the same value

regardless of ++i or i++

Like, know the distinction, but to make your code readable, it's generally best to increment values and then on a totally separate line examine the variable.

Oh I agree

I suppose in some situations it might be nice.

and dont ever write that monstrosity you just wrote @Tromb2ch2 lol

But if somebody was being all like "x+=++i" just for shits and giggles I'd be annoyed.

But the tests on there are people doing that

its conceptual

is why

That's like 50% of the tests
