Error Checking Loop

That's why after three decades of programming I got into the habit of never resolve such a loop exit problem by duplicating the first part just "because a while command looks After I went through the logic on paper like a million times I finally realized my problem... I'd like to have the code run, and then if an error occurs try again until there is no error. Would you like to answer one of these unanswered questions instead? his comment is here

You can't throw an error from within an error handler. The loop will not exit until the condition is false, meaning until the number entered is even. With the now-prevalent preemptive multitasking model, infinite loops usually cause the program to consume all available processor time, but can usually be terminated by the user. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed official site

I started programming about 1.5 years ago. The idea behind indentation is to make things line up. This was actually a problem I asked you guys about before, but now I am trying to add a looped error checking. This is what I have so far: Code: #include main () { int tfhour; /* Intialize tfhour, tfseconds, & twhour */ int tfseconds; int twhour; /* Prompt user for input

To correct the problem, a base case is added. (define (sum-from-1-to* n) (cond ((= n 1) 1) (else (+ n (sum-from-1-to* (sub1 n)))))) This revised function will only run out of Sorry in advanced if it's very messy. #include #include #include using namespace std; int main() { char continueOrQuit; char productName[900]; float productPrice; float totalCost = 0; int productQuantity Was This Post Helpful? 0 Back to top MultiQuote Quote + Reply #5 winggundam3451 New D.I.C Head Reputation: 0 Posts: 15 Joined: 03-October 09 Re: Error checking user input with As well if it's a performance issue because you are running through this look millions of times the for loop might be faster.

If an error occurs in a loop, I normally want to know about what caused the error rather than just skip over it. this content My problem is that the program seems to be getting stuck in the while loop, no matter what they answer. Part of the problem is to have it check for invalid inputs. I hope this was helpful to answer your questions.

If the user enters an odd integer, the loop will tell them they made a mistake and require them to perform the input again. mainly I removed extra code when you check input by putting a do while so the case of wrong input the re-input go back to the first try. i don't get why this obvious translation is a problem. Neverthelss I gave you a +1 for your first version, which is IMHO an example of how to use break properly. –Doc Brown Jan 9 '15 at 17:16 2 This
