for those of you purists that don't like break, continue and goto

[honey the codewitch]

an ironic amen to that. I'm a bit younger, but grew tired of the holy rolling, compounded with me leaving the field and no longer being required to write "team" code, I can just do my own thing As a result I've become a bit more buddhist when it comes to most things coding. There are still certain hills I'll die on though, I admit.

Yep, goto on a lengthier code is definitely not meant for the human eyes. :)

[honey the codewitch]

what's cool about that code though? It's directly translatable from visual graphs of the state objects it represents. I use graphviz to visualize them, and you can see right in the graph where the code matches up. It's beautiful - a 1:1 translation. So the code actually is human readable, you just need the map (the visual graph) for it.

I've seen MS themselves doing it. Sometimes when external code that you don't have control over lacks certain functionality, it might be your only choice. (been there, done that. X| )

right? that's why i *never* throw! kidding! but in seriousness I take great pains to prevent the users of my code from having to catch exceptions on failure if they don't want them. Like I'll provide TryXXXX to complement XXXX Pck: Code Roundup and Quick Start Guide[^] In PCK I have an elaborate error handling system whereby it finds errors and continues processing only (optionally) throwing an exception at the end with ALL the errors it encountered. Otherwise they're reported as "messages" with different severity/errorlevels probably the most elaborate exception handling i've had to do in managed code.

Depending on the length of the array, just let it loop :D I rarely use break or continue (break slightly more often, but probably only a handful in my entire career). I've never used goto, except to mock you I think :D I'd use FirstOrDefault here (which probably uses a break, I don't know). This kind of functionality is embedded in .NET, so why would I write my own? But if I had to pick, I'd choose the break, which far more clearly communicates intent than i=arr.Length;.

if code is hard to write, it should be hard to read. :laugh: i'm a sucker for symmetry.

I have even encountered this in pseudocode, where the author could easily have added a `break` to his made-up exposition-purposes-only language but chose a more obfuscated way instead.

[honey the codewitch]

right, but in the OP i limited i to the loop scope, but yeah.

I prefer break statements. It is not suitable for big projects it might be confusing. I try my level best to write clean code!

[Gary R Wheeler]

Because the second fragment duplicates knowledge of the loop's termination condition. You have to remember to adjust it in two places. The first fragment is therefore more robust.

yep. although there are cases where I'll modify i inside the loop for other reasons. Like if I have to add or remove items while enumerating (it happens with complicated algos)

Yours is BS because it will execute everything after the if.

[honey the codewitch]

It was sample code. Normally you'd account for that when you put actual code in there, but without putting anything in there, it's not for me to know where the actual break should happen. However, it was sort of written with the idea that it would follow the main loop logic, kind of like the break example would. Of course the control flow is slightly different, but it's not irreconcilably different. if you need something to go after the conditional check, you'd wrap whatever went after the break in the one example in an else block instead.

Yeas it the simpliest possible 5 lines code. In real life you would probably have another couple of hundreds lines of similar mess entagled there, with some poor soul wondering why is this piece of crap executing when it was not supposed to.

[honey the codewitch]

:laugh: it's funny cuz it's true. For the record, I'm not endorsing the method i described, I'm simply being facetious about it. I think it's silly. A break statement is much clearer, which was kind of the point of my OP. Sometimes you need break. Or a continue. Or even a goto (which i can give a solid use case for - in this case making the code MORE readable)

Alright, here a piece of advice: never exit conditionally a for cycle. if you need to do that, use while or do until.

[honey the codewitch]

i think it depends on the situation for example

public int IndexOf(T item)
{
var ic = Count;
var i = 0;
for(;i

That's very clear even without comments

i=-1 do i++ until Equals(item,this[i]) return i

[honey the codewitch]

i mean yeah. That's a little less clear to me though. I avoid do loops usually because the conditional can get confusing if you're used to regular for loops. It takes me a second to work out what's going on, like when exactly the condition exits. It's not big deal, it's just my preference. I think my code is clearer.
