What will displayvalue(2, {0,1,2}, {"A","B","C"}, "Unknown") return?

• A. A
• B. B
• C. C
• D. Unknown

Answer: (C)

This tests how a value is mapped to a user-friendly label using two parallel lists and a default fallback. The function looks for the given value in the values list and returns the item from the displays list at the same position; if the value isn’t found, it returns the default. Here, the value is 2. In the values list {0,1,2}, 2 is at the third position. The corresponding item in the displays list {"A","B","C"} at that same position is "C". So the function returns the string "C". The default "Unknown" would only be used if 2 were not present in the values list.
