[FrOzeN]

Code Select Expand

BEGIN FindDogOwner (req_microchipno, req_ownername)
    found = false
    open (Owner) indexed by microchipno
    read (Owner) microchipno, ownername
    WHILE not found OR not end of file
        IF microchipno = req_microchipno THEN
            req_ownername = ownername
            found = true
        ENDIF
        read (Owner) microchipno, ownername
    ENDWHILE
    IF not found THEN
        print 'no owner recorded'

        print 'owner is '; ownername
    ENDIF
END

Question: What type of variable is 'found'?
  (A) A constant
  (B) A flag
  (C) A string
  (D) A trigger

Just post either A, B, C or D depending on what you think/know the answer is. I'm going over HSC tests from previous years, and found the answer they said for this one to be different to what I thought. I'll post it after some replies.

Also, HSC stands for "High School Certificate", it's Australian. It would be equivalent to whatever the most important exam you do in High School in America/Canada/etc..

Secret answer E) a boolean variable.

[FrOzeN]

Boolean was my first thoughts when reading the question, before seeing the choices. But unfortunately it's not it.

I'd think it was a trigger.

[FrOzeN]

The answer I put down was trigger. (I just opened notepad and did the first 20 questions to see what I'd get).

But the HSC says it's a flag? I would of assumed a flag would be a Integer/Long (.. if anything). Can anyone fiqure out why it's a flag?

flags are booleans

[FrOzeN]

flags are booleans

Oh, ok.

Are triggers anything, or just part of the 'fake' answers?
