do you use goto? [modified]

Actually, goto isn't *that* bad. In fact, MFC Framework code uses goto for handling initialization failures. But, I'll agree if you say that one will need goto very very very rarely. :)

Rule #1: Don't use goto. Rule #2: Know when to break Rule #1. Personally, I haven't come across an instance where I had to follow Rule #2.

In a situation like this[^], I *will* use goto. And yes, I know what I'm doing.

Yes, but the rules (as Vikram so adequately pointed out in his post below) is not for the exceptions but for the general case. Besides, Personally, I'd go for Judy's method (following the link you posted) as opposed to the goto method. Ugly as sin it may be but I find it readable and it maintains "the rule".

I don't use Goto and I get rashes when I see one. So, how about Exit/Break? Is that justifiable?
Justify? Before whom? If something serves the task at hand better than anything else then use it. How about letting those who try to enforce some rules at all price let do the justifying for a change? You might discover that many just howl with the wolves, but don't actually know why. In my opinion many of the rules are not written in stone. They are supposed to help us, but chaos does not automatically break lose if you decide to ignore them.
A while ago he asked me what he should have printed on my business cards. I said 'Wizard'. I read books which nobody else understand. Then I do something which nobody understands. After that the computer does something which nobody understands. When asked, I say things about the results which nobody understand. But everybody expects miracles from me on a regular basis. Looks to me like the classical definition of a wizard.

Hey guys, My former team mate used goto's quite often (to my despair). I just published a small post on when to (not) use goto on my blog[^] where I try to look at this in a pragmatic way. I am interested if you are using goto's (or know someone who does?). Opinions? cheers, Pakl PS: This is just a blunt advertisment for my blog so I can lure you into it and become rich and famous. :-\

No. I've simply never found a need for it in any reasonably coherant programming language.

My opinion in using gotos is like C programming: it is up to the programmer to code properly. Some are so skilled to write ugly C code. If used properly, goto can could may might have a place in our hearts. E.g. the MS-DOS batch script below (tested on WinXP):
@echo off set i=0:loop
set /a i=%i%+1
echo Loop %i%
if not %i% == 10 goto :loop -

Not explicitly, anyway. If you've ever used a C break or continue, implicitly you have, since break and continue are simply goto's with an implicit label that is just outside or inside the current end of scope.

By that reckoning anyone using an if ... then ... else is also using a goto. The argument is not that "jump" statements in a program are not required (in any non-trivial program they are unavoidable), but that structured programming constructs rather than the goto statment lead to more understandable programs. As Dijkstra said in his original letter[^] - "The go to statement as it stands is just too primitive, it is too much an invitation to make a mess of one's program." I haven't used a goto statement since I gave up programming in Basic

Again, not really. I've encountered situations (even recently) where I felt that a few goto statements will save me from writing a buttload of ugly nested if-if-if statements.

Doesn't bother me at all to use goto. I haven't found a c++ compiler that doesn't support them. They're not evil, just one more programming construct. If it saves me 100 or 10 or even one line of code, I'll use a goto without thinking twice.
