Stop Values.

[afatbahmed]

i came across a question in a clad sample exam. it says

all of the following are traditional debugging features used to help find errors in a vi, except

1. highlight execution   2.breakpoints   3. stop values   4. single stepping

i didn't get what stop values were.please help

Sometimes terminology is what makes these questions difficult to answer, not the actual concepts. If I had to guess I'd say they're probably referring to having probes with conditions set to pause execution in case the value of the wire meets a condition. Not sure why it would be called a "stop" value since you're not "stopping", but "pausing". Again, it's a terminology issue.

Since this is an "except" question, it is really a question you answer by elimination after validating the other choices

1. highlight execution - definite debugging tool, you can find it as the lightbulb on the toolbar

2.breakpoints   - definite debugging tool, you can right click on wires and structures and set breakpoints

3. stop values   - sounds like a debugging tool, but kind of confusing what it means precisely.  Sure you can stretch things and say "they're probably referring to having probes with conditions set to pause execution in case the value of the wire meets a condition".  That sounds reasonable.

4. single stepping - definite debugging tool, once you've paused the VI, you can execute it one step at a time.  The options are shown in the operate menu.

The correct answer is number 3, because you can eliminate #1,2,4  because you can identify precisely what they are talking about.

Generally with any kind of multiple choice question, if you try to read to deep into it, it means you are probably going to get it wrong.

i appreciate your effort in answering my question but even if it is ( the stop value ) some condition in the custom probe application doesn't that fall into the catagory of debugging techniques. Maybe i didn't understand you the way you wanted me to.

Ravens Fan is correct. Since none of us have ever heard of the precise term Stop Values, it's seems pretty obvious that the answer is 3. Don't read more into the question than is actually there.

I'm not sure whether you are replying to smercurio or me.

The answer is #3 because all the other choices precisely define available LabVIEW debugging tools.  A custom probe application would also be a debugging tool, but that is not once of the choices on the list.  The extra answer is "stop value".  While that sounds like it would be a debugging tool on the surface, it doesn't really identify anything in particular.

The question was written to be just a little bit confusing to distinguish between those who know what the LabVIEW debugging tools are and those who might just be guessing.

Hmmm.... it seems that the test makers put in something that no one ever heard of but that almost sounds legitimate.  They probably should have put something in there like "Semaphores" or "Connector Pane" or something like that.  On the quizzes I make up for my students (physics class), if there are some fake answers I usually make them very fake -- like "flux capacitors" or "Dilithium crystals".  The problem here is that they had to make up just one... and it had to make sense.

i get too conscious and hang on to every last detail. i'll try to be a bit more non-chalant next time. thankyou

I completely agree with you but in the sample exam key, the correct answer was:

C. breakpoints.

I think there is an error in the exam key.
