Thanks! Introducing an extra variable that needs to be kept track of just to dodge a break or continue is counterproductive. http://danshuster.com/apcs/java0306.htm

I have to guard against letters and any input which would be an invalid bet. What is the bandwidth cost of running a full node? You can even better wrap the get input logic in a separate method, so that the main logic looks like: inputNumber = getInput(); calculateAverage(inputNumber); and you put the looping in getInput(). For example, if LabVIEW encounters an error, you can display the error message in a dialog box.

This is only the first step. I did not know that !(cin >> input) was valid either. I'd like to have the code run, and then if an error occurs try again until there is no error. cin.sync() is not guaranteed to do anything useful.

I am aware that this code does not check of EOF.

Check what you have before posting and make corrections if the post looks like crap. this content check block integrity on every memory call dbgFlags |= _CRTDBG_CHECK_ALWAYS_DF; // Don't always remove blocks on delete dbgFlags |= _CRTDBG_DELAY_FREE_MEM_DF; // Check for memory leak at process termination dbgFlags |= _CRTDBG_LEAK_CHECK_DF; Also, work on your formatting. This helps maintain the integrity of the data entered by users and ensures that the program will not continue until it receives the correct information.

But imagine such a situation in real world code, where introducing bugs accidentally can have real consequences - then you might think different about it. Let's modify the above code to see an example. I want the program to end once the program is completed correctly. http://oncarecrm.com/error-checking/error-checking-loop-java.html Thanks for the tips.

This is what I have so far: Code: #include main () { int tfhour; /* Intialize tfhour, tfseconds, & twhour */ int tfseconds; int twhour; /* Prompt user for input Forum Today's Posts C and C++ FAQ Forum Actions Mark Forums Read Quick Links View Forum Leaders What's New? Is there a word in Esperanto for "lightsaber"?

It uses cin.fail() to check if the input is invalid.

When you perform any kind of input and output (I/O), consider the possibility that errors might occur. Almost all I/O functions return error information. Do you think my teacher is right? be clear on the expected behavior and the problematic behavior you encountered.

Then place in */ /* twhour's postion */ if (tfhour >= 13 && tfhour <= 24) twhour = (tfhour - 12); /* Print twhour & seconds value with output */ printf("Equivalent Stopping a While Loop Learn LabVIEW Basics in a New Way Learn these LabVIEW concepts though our new, interactive experience. If an error occurs, the loop stops. check over here Or you can fix the error programmatically and then erase the error by wiring the error-out output of the subVI or function to the error in input of the Clear Errors

i don't get why this obvious translation is a problem. Use error handling with the debugging tools to find and manage errors. In Figure 1, the error cluster and a stop button are used together to determine when to stop the loop. I have the error checking working just fine for the unit of measurement its checking the int is the issue.

Try again!"); System.out.print("Enter an integer from 1-5:"); number = keybd.readInt(); } System.out.println("Thank you!"); In closing, The while loop version of error-checking is much more useful share|improve this answer answered Jan 9 '15 at 4:18 jdevlin 33116 Your answer looks nice - but only on a first glance. This problem does not only apply to just cin.fail() checking.
