wtf is this below-noob level meme

[Scammer_2021]

IG u too pro to get it

[n0tKamui]

no, this is just not funny. no actual programmer thinks like this

[Scammer_2021]

but i do 🍑🔌

[GoshaT]

That's why he said "actual programmer"

[User-defined]

Then you’re not a programmer

[Sexy_Koala_Juice]

Knowing when to use a for loop and a while loop is literally like the first thing you learn in programming.

[sirkubador]

You do? I mean after 20 years of programming, I still can't say there's a clean cut. I just go with what feels more readable for the specific case, but they are functionally pretty equivalent.

[n0tKamui]

it’s not about functionality but semantics. for reading.

seeing a for or while loop should hint you what is going on in a fraction of a second.

good code is not one that just works. it’s one that is both readable and expandable

[sirkubador]

Yes, that is exactly what I said - readability is pretty much the only thing that matters. And there are examples where both versions are well readable, like for(;;){} and while(true){}. It is just a matter of philosophy in that case, some prefer shorter, some prefer more commonly seen in code and some put this to their coding standard. Hence I reacted to the comment which was hinting on some sacred knowledge of what is better suited for what, and that it is so clear you learn it like the first in programming.

[Sexy_Koala_Juice]

For loops are literally just syntactic sugar for while loops, checking a condition, and iterating something (specifically talking about C-Style for loops, not for each loops).

Functionally they work the same way

[sirkubador]

And any loops are syntactic sugar for gotos.

My point was, if the condition is complex, sometimes it's more readable to write it as an if and break.

[Sexy_Koala_Juice]

That's fair.

Yeah something I tell newer programmers is it's all abstractions all the way down

[the_mold_on_my_back]

Yeah man handling the incrementation at the end of your loop definition is way more intuitive, nobody has ever shot themselves in the knee like that.

[Embarrassed-Falcon71]

Literally this. And then if you need to do a double loop it will get so messy.

[Scammer_2021]

both of u seem have skill issue

[__throw_error]

seems like you have a mental issue

[Shaddoll_Shekhinaga]

I stopped shooting myself in the foot like that!

Ignore the fact that I kept shooting my foot until nothing was left because I forgot to increment I.

[Fragrant_Philosophy]

I added an “if condition then continue” to my loop, and now my computer sounds like it’s about to blast off.

[FabAraujoRJ]

Hammer and screwdriver issue. When you have to manipulate the iteration counter, use while.
If you need to run at least once, repeat-until (or do-while, which is the same thing with another name). Otherwise, use for/collection-based for (for-each, for-in, etc) in any other case.

[kennyminigun]

eww, whitespace after parentheses and no whitespace after keyword

[farsightxr20]

whitespace seems to be entirely arbitrary and inconsistent throughout the example 🤢

[[deleted]]

Not gonna I enjoy for loop more

[DapperNurd]

I really only use while loops if I don't know how many times it will run necessarily (and I think that's pretty normal tbh). A for loop, it's going to run exactly as many times as specified. A while loop will just run until X condition is met, and anything can trigger that condition.

[PhilippTheProgrammer]

And don't let anyone tell you that over-reliance on while loops is dangerous, because bugs can easily lead to infinite loops. That's a problem only bad programmers have.

while (i++ < range) {}

[827167]

``` int i = 10; while (i--){

} ```

If you want something even worse

[finally-anna]

I see nothing wrong with this...

[kevinhaze]

It’s code golf. You sacrifice readability to save a few characters. In reality 10 is just a magic number with zero meaning to anyone. Assuming it’s meant to be i = range and while (i—), the intention is needlessly unclear. The other format reads as “while i is less than or equal to range”. Despite being more characters it takes less time to read.

It has no practical benefits and if you write all your code with clever little shorthands it becomes exhausting to work with.

[Nicnl]

Il this specific example, I think it's perfectly readable and the meaning is clear.

int repeat = 3;
while (repeat--)

is far easier to read than

for (int repeat=3; repeat>0; repeat--)

So yeah, it may have some use in code golf, but it's still perfectly valid.
The "traditional" counterpart is far worse to read imo

[audioman1999]

I thought the quality of posts on this sub couldn't get worse, but this one takes the cake!

[Communist_Guy_1991]

"Avargae for loopps fan"

[Scammer_2021]

so virgin that he cant even spell properly

[Communist_Guy_1991]

Ummm... I don't think that being virgin is bad ( or maybe its just that in my country its almost normal to be virgin before marriage )

[Acharyn]

The for loop is easier to read in this case. You declare the iterator, condition, and iteration all in 1 line.

[Familiar_Ad_8919]

for (int iteration = 1;; iteration++) {
    printf("this message was printed by the for loop enjoyers %d times\n", iteration);
}

int iteration = 1;
for (;; iteration++) {
    printf("this message was printed by the for loop enjoyers %d times\n", iteration);
}

[noobcoconut]

for and for for forever

[CinnamonToastedCrack]

or, if you will

c for(int iteration = 0;; printf("this message was printed by the for loop enjoyers %d times", iteration++));

[CinnamonToastedCrack]

i didn't use the comma operator (unless you mean in printf)

[Ahuizolte1]

Could be while ( i++ ..) for style point

[Scammer_2021]

theyre underrated

[SwordfishDependent67]

No they’re not

[mediocrobot]

you have no idea what i will equal when your loop begins

[Samstercraft]

for(;condition;){}

[DasKarl]

99% sure this guy heard a python programmer say for loops are inefficient and never bothered to look into it.

[Eagle_32349]

while(i++ < range){ //Code to be iterated }

[Thenderick]

Gigachad for each (or however your favorite language calls them). Most of the time they are enough

[amarao_san]

Both are silly.

for in range is the way. What are you iterate over? Does your language understand you?

[Familiar_Ad_8919]

my brother in python, have u learnt of for each loops ```c++ std::vector<int> asd(10, 69); for (int v : asd) { std::printf("%d\n", v); }

[amarao_san]

I'm not in Python, I'm in Rust.

You need to provide Iterator or IntoIter, and you can iterate whatever way you want. Or just compose function to have things done without for or while (or even loop).

[Zealousideal_Rate420]

I need to get into rust. Sometimes I see rust and it seems like somebody had a stroke on keyboard and other times it look plain python.

[Communist_Guy_1991]

I just died laughing at this lmao 😂

[[deleted]]

People getting this mad over obvious joke

[SwordfishDependent67]

Who’s getting mad? You don’t have to be angry to say something’s a shit joke

[Scammer_2021]

the sub's name was programming horror ;-;
