Searching Strings

[SercoSteveB]

What are the values of Boolean Out 1 and Boolean Out 2 following execution of the VI?

a) Boolean Out 1 = FALSE, Boolean Out 2 = FALSE

b) Boolean Out 1 = FALSE, Boolean Out 2 = TRUE

c) Boolean Out 1 = TRUE, Boolean Out 2 = FALSE

d) Boolean Out 1 = TRUE, Boolean Out 2 = TRUE

Initially I guessed D. But later when I looked into the description I go with B. The \ does the trick here.

Nice one steve:)

B - Match pattern searches for a regular expression in the string - and the regular expression for a left bracket is \[

Haha, similar to gnshmrthy Initially I thought A, then I recognized the different behavior 😉

B Nice trick question. I like those.

B

[MrStevenUND]

tricky.  B.  Me and regular expressions don't get along very well...

B.

match pattern: requires special expressions for finding certain characters. \[ for finding [. Therefore returns -1 for [

search split string: interprets input expresssion as regular characters. \[ means \[.

For [, it would return the index of character immediately after the first match.

Answer: B.  Nice one gnshmrthy, Stuart89, Andreas23, LordNobady, crossrulz, MrStevenUND & kasliwal.

Different behavior across two functionaly similar VIs.  Exposure (and subsequent understanding of the difference) is the way to go on this one.

B. thanks for tricky question.
