Try again!"); System.out.print("Enter an even integer: "); number = keybd.readInt(); } System.out.println("Thank you!"); In this version, the if statement is replaced by a while loop. his comment is here

A C-like pseudocode example of an Alderson loop, where the program is supposed to sum numbers given by the user until zero is given, but where the programmer has used the My standard error handler that is used on every procedure looks like this. Please help improve this article by adding citations to reliable sources. From now on, when writing error-checking code, use a while loop. Clicking Here

In some cases other signals such as SIGKILL can work, as they do not require the process to be responsive, while in other cases the loop cannot be terminated short of Thanks so much for your solution –user3505632 Dec 10 '14 at 4:25 add a comment| Not the answer you're looking for?

This article needs additional citations for verification. What would be a good approach to make sure advisor goes through all the report? Error Checking Loop Thus, a will never be able to advance to 10, and this loop cannot terminate. While most infinite loops can be found by close inspection of the code, there is no general method to determine whether a given program will ever halt or will run forever;

end). http://megavoid.net/error-checking/error-checking.html For real-world code this would be a no-go, since it becomes error-prone (when you have to change that part later, you will have to make sure you don't forget to change A loop forever is not always a bad choice (although it usually is) in this case it is obviously a bad choice because it communicates the wrong intent of the code. I'd argue the problem with the initial code is that the loop never finishes an iteration normally, and that you need to know there's a continue inside the if to know

But the only time we get here is if it's red. Apparently, there is no possibility for an infinite loop in the server, but if there are two such servers (A and B), and A receives a message of unknown type from Therefore, the loop becomes an infinite loop if the codition is true and will get continue to loop indefinitely.

We can use the following to ensure correct input: System.out.print("Enter an integer from 1-5: "); number = keybd.readInt(); while(number<1 || number>5) { System.out.println("Bad input.

I have therefore put some code into my error logging function that detects identical errors and skips writing them to the error log. If Nz(ErrCode, 0) = ErrCodeOld And Nz(Source, "") = SourceOld And Nz(ErrData, "") = ErrDataOld Then NewErrorLog = True MsgBox "Error has occured in a loop: " & Nz(ErrCode, 0) & If the inputed value gives */ /* a 1 off when divided then it equals PM */ if (tfhour / 12 == 1) printf("PM\n"); else printf("AM\n"); return; } Any advice?
