Oddly enough, this is the general province of a "break" statement.

Using multiple goto statements would however add a routed break from the loop instead of restarting right from end of the loop statement.

example, the following psudocode:-

:banana:

I know the CASE statement can be used in the above code, I never said using GOTO is good coding or the best solution, in all situations I would agree that it would be best to code it in another way.

And you can't figure out how to do that properly? Shame on you. Hit the books and make sure potential interviewers don't see your post.

wow you're fast. I was editing the post above, sorry. I posted it and then said to myself. hmmm Da wei is gonna shoot you down, you better state the obvious. sigh so said so done :p

DaWei

I apologize if the response seems a little strong. I have some concerns about novices being misdirected or instructed in gross error. It seems inappropriate to me (personal opinion, of course, but shared by a large majority of competent practitioners) that an example of bad programming practice would be deliberately provided.

As DaWei rightly points out, there are better ways to get the same functionality. Refactoring your code to use the common "break" statement is simple enough:
Although for code that seems to handle errors, exceptions would seem the best tool to use:

Hmm, I read an article a while back which advocated the use of gotos in a lot of cases -- I can't say I agree with the article, but it was a well-written article nevertheless. I can't seem to find it though, if I find it I'll link it.

I feel compelled to add that there are televangelists that make well-presented arguments to seemingly rational people and are successful enough at it that they commute between mansions in Learjets.

I didn't exactly write a well-thought-out and immaculately presented treatise in post #29, but I think it hints at the very few situations where the use of a goto might be advocated. It's not a LOT of cases, by any stretch of the imagination. I would look askance at one who preaches otherwise, however eloquently.

One may make a case that in a language without exception handling, the equivalent functionality might be implemented using 'goto.' I reiterate that the task should be undertaken by one who is intimately familiar with what happens to system state before and after such machinations.

You keep popping things into the thread that indicate you STILL have no idea what we're talking about. "As I said..." indeed! Good of you to dictate the end of the story, though, we were waiting on an authoritarian figure to do that.

You're excused.
