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

why do this?
for(int i = 0;i
instead offor(int i = 0;i
hengh?? why you still use break?

breakis a lot clearer - and less likely to cause problems later if theforloop end condition gets modified.Sent from my Amstrad PC 1640 Never throw anything away, Griff Bad command or file name. Bad, bad command! Sit! Stay! Staaaay... AntiTwitter: @DalekDave is now a follower!

if it matters enough to be a purist about it, then i think it matters. if it doesn't matter to you, you're not a purist about it. :laugh: bow before my tautology!

rather my point. sometimes you need a good break, continue, or even a goto (though the latter i typically reserve for generated state machines)

My personal preference is to use the
break, as when later on when someone adds more logic before that final brace you now have potentially undesirable side effects with having mutatediwithin the loop. I can see the possibility of arguing it either way.“That which can be asserted without evidence, can be dismissed without evidence.”

My guess is that would put you in the minority. As for me, I prefer the break, but then I have no qualms about continue, return, goto, or other "out of band" control flow - pretty much except "throw" which I never use as a control flow statement (though I've been forced to use catch for that occasionally due to Other People's Code - *sideeyes Microsoft's HttpWebRequest class*) i just try to keep the out of band stuff near the top of my scope where people can see it.

I do as well, but then i have no qualms about any out of band control flow statements except throw. It's all in how and where you use them, IMO.

throwwould be even more clear, definite and failure proof. (well I do see many kids using exactly that to 'not usegoto endlabel')Message Signature (Click to edit ->)
throw is worse than goto, IMO for control flow.

I love goto. Lets go-back-to VB. :-D I've made use of gotos to a great extent during my VB times. like, On Error: GoTo the magical origin of the universe. An equally 'powerful' instruction - JMP. But JMP is never ashamed of being JMP, cuz it's assembly. You can go roam anywhere you want, it's got the license. :laugh:

Throw doesn't belong to the control flow. Oh, maybe I'm a bit purist after all.

ugh, VB. I use goto in some of my code. Perfectly acceptable place to use GOTO - generated state machine code:
public static bool AcceptsByte(Grimoire.ParseContext pc)
{
pc.EnsureStarted();
if (-1 == pc.Current) return false;
if ((48 == pc.Current))
{
pc.Advance();
goto AcceptsByte_s1;
}
if ((49 == pc.Current))
{
pc.Advance();
goto AcceptsByte_s2;
}
if ((50 == pc.Current))
{
pc.Advance();
goto AcceptsByte_s4;
}
if ((51 <= pc.Current && 57 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s3;
}
return false;
AcceptsByte_s1:
if (-1 == pc.Current) return true;
return -1 == pc.Advance();
AcceptsByte_s2:
if (-1 == pc.Current) return true;
if ((48 <= pc.Current && 57 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s3;
}
return -1 == pc.Advance();
AcceptsByte_s3:
if (-1 == pc.Current) return true;
if ((48 <= pc.Current && 57 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s1;
}
return -1 == pc.Advance();
AcceptsByte_s4:
if (-1 == pc.Current) return true;
if ((48 <= pc.Current && 52 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s3;
}
if ((53 == pc.Current))
{
pc.Advance();
goto AcceptsByte_s5;
}
if ((54 <= pc.Current && 57 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s1;
}
return -1 == pc.Advance();
AcceptsByte_s5:
if (-1 == pc.Current) return true;
if ((48 <= pc.Current && 52 >= pc.Current))
{
pc.Advance();
goto AcceptsByte_s1;
}
return -1 == pc.Advance();
}but then I wouldn't write that code by hand. Too error prone.

i mean, i agree that it shouldn't, but it causes control flow changes and can be used that way. but like i said, i agree. Just because you can do something, doesn't mean you should.

I agree, my experience is that as a generalisation us developers have very strong opinions. At the age of 49 I have found that I no longer have the desire to get into arguments over this sort of thing - as in six months time the 'best practise' recommendation will in all likelihood have switched.

If you enjoy pain try mixing throw with interop. (sure way to properly destroy documents and pst files.)

oooh. Another place i like to throw is in static constructors, just to get absolutely everyone's BAC up. :laugh: I'm kidding. I'm not a sadist.
