I'm not very familiar with how the function treats the convert EOL option and how it behaves with the CRLF, but one important point to consider is that at least according to the documentation, the function will not create folders, so if the folder isn't there, option B should be the correct answer.

It's important to remember to create the folders where you save files - there's an OpenG function which does this, and in current versions of LV I believe the create folder function also manages the whole hierarchy natively, but I believe it also returns an error if the folder already exists, which the OpenG VI does not.

That is all correct.  The error the native function returns if the folder exists is 10: Duplicate File.

B - If we assume the folder does not exist.

C - On the assumption the folder exists.

i go with D because the array which created is 2*1 so i think evry time it write to filem is two lines

No because without the carriage return/linefeed you would get:

SteveLikesLabVIEWSteveLikesLabVIEWSteveLikesLabVIEWSteveLikesLabVIEW

with no new lines included.

It's not an array, it is a concactenate string.

Thanks for the correction yes its Answer is C

[eleshrudra]

answer is C

[SercoSteveB]

Original Answer: C.  Answer after tst having given it the thought I should have:  B or C. 

Nicely explained above, thanks tst.

LabVIEW help:
"This function appends platform-dependent, end-of-line (EOL) characters to the elements of an array even if you right-click the function and remove the checkmark next to the Convert EOL shortcut menu item."

So what is that for?

But I've made interesting observation:

[littlett]

Hi,

Can anyone explain what's the difference between "Convert EOL" checked and unchecked?

Thanks,

[crossrulz]

It is mostly used to multi-platform text files.  In Linux (like the newer cRIOs), the End Of Line (EOL) is a Line Feed (0x0A).  On Windows, the EOL is a Carriage Return and a Line Feed (0x0D0A).  So the option will help convert between the multiple types of EOLs.

With Internet Explorer and Windows 10 I can not see any difference between answer c and d.
So I copied all answers to MS Notepad. Now I guess answer c is with 2 times CRLF between the text and answer d is wit 3 CRLF between the text. So finally not A, B, D. Remains c (as long we have the correct path)
Thanks crossrulz for the Explanation.

Hi, 

for those People  (like me) that dont see the differences between C & D am there is a Problem showing the empty lines betwen These String in D):

Copy pasting it from Microsoft Edge into a txt File:

The funny Thing is when copying from goole Chrome there will be an empty line between all strings

Please correct me if am wrong.

Seriously how is this an exam question... NI examiners need to test the competency of technical computing than string manipulation, I am a bit disappointed. Anyone could generate this in C or MATLAB without lifting a finger 😉  

[crossrulz]

Yes, this is a stupid simple application.  That is not the point of this question.  This question is more about somebody's knowledge of the Write Text File function than anything.
