Most gratuitous use of 'goto'

Nish Nishant

Here's what I could come up with in these early morning hours :-

void GetBiggest(int x, int y, int z, int& big)
{
for(big = x; big < y; )
goto check1;
for(; big < z; )
goto preexit;
goto exit;
check1:
for(big = y; big < z; )
goto preexit;
goto exit;
preexit:
big=z;
exit:
;
}

I hope, it's okay for your purpose Chris. :rolleyes: Nish

I once (many years ago) used goto to swap two lines in my basic code (something like this):

goto a1
a2:
' something in basic
goto a3
a1:
' something in basic
goto a2
a3:

wasnt this a non-coding forum!? :cool: Don't try it, just do it! ;-)

I ran across some code where 'goto' was used to go to the end of a 'for' loop and do the next case. I think it's beause somebody didn't know about the continue statement.

I said "goto" not "coding". There's a difference :P cheers, Chris Maunder

I have come across quite a few programmers that don't know about continue.

Well, when i was very young, i wanted to stay up and watch TV all night, but my mom said "goto bed." I certainly felt that was inane, as well as just plain wrong. ;P

Anyone on my team who dare's using goto is fired on the spot :mad:

A number of years ago Microsoft published the DefWndProc source code, which is what you call from your WndProc after you have processed a windows message. I believe the function was over 3000 lines of code, although I have seen such long switches in Excel functions, too, but maybe not that long. There was a label called "ICantBelieveIUsedGoto" in the function, that went from one location of the function to another location. What I don't understand is why each case could have been broken out into a separate function, thus making it easier to maintain. Oh, yes, I remember, because this was windows 3.1. Thanks, Wes

are they allowed to use "continue" and "break" ? bryce --- Publitor, making Pubmed easy. http://www.sohocode.com/publitor

I have been programming for 20+ years and never ever found any use for continue or break (except off course break in a switch statement), so to answer your question, no, they cannot. The same goes for the return statement. There can be only 1 entry point for a function and only 1 exit point. We always use a local var (result) to set the return value of a function. Using statements like goto, continue, break and return (the latter used in the wrong place) leads too often to "spaghetti code" IMHO.

bryce

as long as you're consistant :) i've heard people moan about the use of "goto" but they'll happily use break and continue... bit oxymoronic if you ask me :) Bryce --- Publitor, making Pubmed easy. http://www.sohocode.com/publitor

I do use continue and break probably 1 time in every 10K lines of code I write. The multiple returns probably 1 in every 2K lines. I have not used a goto in several years so the ratio will probably be like 1 in every 250K lines I write... John

There are definitely times when using continue, break, and return is actually better than not doing so. But when you find yourself needing to do it, it's important to ask yourself if there is a better way - breaking the function up into multiple functions, etc. If you say absolutely no gotos/continues/etc, occasionally you'll run into a place where in order to go by your rules you'll have to produce code that's more like 'spaghetti code' than if you allowed its use. * Believe me - I've seen this before (not very often, though). *Most of the cases were in complex string parsing functions.

I for one actually don't know how to use 'goto' Nor do I understand why it is used. Regardz Colin J Davies

here: TRACE(_T("I love Code Project and me! hehe haha\n")); goto here; I think the only time I've ever used goto was for "cleanup" purposes within a function. I do remember coming across a Microsoft VC++ sample that used goto - if I'm not mistaken it was one of the multimedia samples.
