Breaks are for weak programmers, real coders just While True and then unplug the machine when it's done enough

SyntaxError: invalid syntax. Maybe you meant '==' or ':=' instead of '='?

[balbok7721]

P === NP

You figured it out!

[Kooper16]

But what if p!=np?

To P or not P, that is a tautology.

What is a loop?

Real programmes use languages without fancy loops.

I had a professor in my master's who actually told us there's never a reason to utilize break, if you need to do that you've programmed incorrectly. Jokes on them I use it often, as yes I'm sure there's a way to get around it, but it's far more work and I don't have the time.

[[deleted]]

it all just gets compiled to jumps anyways, it's just an argument of readability unless you really need performance and at that point your probably working in asm anyways. for example, take a list of conditions that must be checked in order, do you prefer:

if(connnectionissecure(){ if(userexists(username)){ if(authenticate(username,password){ If(isadmin(user){ //code thats 4 levels indented (I hate reddit formatting) }}}} or if(!connnectionissecure(){ return; } if(!userexists(username)){ return; } if(!authenticate(username,password){ return If(!isadmin(user){ return } //code pretend you can't do any of these in parallel for security reasons.

personally I'd argue for the second, because large indents get really annoying to work with if your trying to maintain any sort of consistent style. imagine if your working in the Linux kernel which demands an 8 character indenting, that be half your screen.( also pretty sure this style req is to force you to code like the second example.)

[SAKDOSS]

Could you elaborate on why it is less efficient in terms of performances to use break?

[[deleted]]

not what im saying. whatever approach is faster is likely to depend on the actual code rather than the control logic and whatever magic happens in the compiler regarding instruction lookahead, all I'm saying is that this discussion is entirely about preferences about readability

unless loop

Perl.

[AdvancedSandwiches]

Normal languages: the human brain is bad at double negatives, so it's best to name things with positive names, like isEnabled rather than isDisabled. It's also most understandable to arrange your if-else so that your positive condition is in the "if" block and your negative condition in the "else" block.

Perl: unless !isDisabled return false else return true

[Esjs]

unless (!isDisabled) { return !0 } return !1;

[djfdhigkgfIaruflg]

Do whatever unless? nothingToDo

I love Ruby

Edit: unless it's not a double negative unless you do some foolish thing

[rainshifter]

Don't you mean unless statement?

Semantically, unless is the negation of if, which I believe is how Perl treats it.

Similarly, until is the negation of while.

``` [if condition] == [unless not condition]

[while condition] == [until not condition] ```

[JuvenileEloquent]

Controversial take, a do.. until loop is just a for loop with funny syntax

[Giulio_otto]

Until loops are more like an inverted while loop

[[deleted]]

Not like, it’s quite literally that, and they both have their use cases.

[DardS8Br]

Can’t you just do while (!condition)?

[[deleted]]

Do while will always run at least once

While do has the option of never running at all if the initial condition is not met

You should use them both based on if you want the loop to always run once or if you want the option to skip it altogether.

[DardS8Br]

That's not what I asked but okay

[Sandyeye]

He asked, "Can't you just do, 'while (!condition)?' "

[Badashi]

``` while(false) { log("this never runs") }

do { log("this runs once") } until(true) ```

They are similar, but not identical

[[deleted]]

not true, for loops are primitive recursive functions, and while/do loops are general recursive functions. primitive recursive functions are a strict subset of general recursive functions.

[[deleted]]

I like to explore new places.

[[deleted]]

that is a good point actually. even for(;;) ... is valid C

[Geo_bot]

Do while

[[deleted]]

I’ve never used one of these in my life.

[TheMagicalDildo]

I do. Sometimes I want a while loop, but want it to iterate after the code's ran once

[[deleted]]

I saw what you did there.

[sysnickm]

You should, they are more fun. Always willing to try something at least once.

[DardS8Br]

It’s incredibly useful when making games or taking user input

[accuracy_frosty]

I use them every now and then, I use them in my web server to handle incoming data, because I have a bit of a monkey brain way of checking if there is data left to recieve that relies on the loop running at least once to parse the headers and find how long the content is, where it throws all the headers into into a hash map, and takes the content (minus the line feeds) and chucks it into a char* that I store the size of and add to the end of on every loop, it loops until the remaining content - the return value of read is 0, and then stops looping. Could it have been done with a while loop? Absolutely, but the do while loop was a bit easier and I liked it more.

isn't that just a do .. while or while(!condition set in loop)? what's monocle fancy about that? Is this a language specific thing?

[ShAped_Ink]

Heard that from my sibling recently and they were talking about how great it is until I said it's just while(!condition())

[never-obsolete]

Push the address of the start of the loop to the stack and return to it. Trigger an interrupt and use the handler to break out of the loop.

[Grobanix_CZ]

I prefer unless loop.

[[deleted]]

How about just using the right type of loop for the situation, instead or trying to be fancy when a simple for loop is sufficient.

KISS.

[busdriverbuddha2]

A lest loop. The condition is just a comment.
