Question #3

Review the code snippet.

What value does the code output?

Reveal Solution  Discussion  0

Correct Answer:

Answer the question by typing in the box.
2
Explanation:
This question belongs to Swift Programming Language , specifically the objectives covering functions , control flow , and default parameter values . The function is declared as func getAgeCategory(_ age: Int =
20) - > Int, which means if no argument is supplied, Swift uses the default value 20. Apple's Swift documentation explains that you can define a default value for any parameter, and that value is used when the caller omits that argument. Since the code calls getAgeCategory() with no parameter, the function executes using age = 20.
The conditional logic is then evaluated in order:
* if age > 64 # false, because 20 is not greater than 64
* else if age > 19 # true, because 20 is greater than 19
* so the function returns 2
Because Swift's if / else if control flow stops at the first true condition, the later checks are never reached once age > 19 succeeds. Apple describes Swift as supporting standard control flow including conditional branching, and this example is a direct use of that branching behavior.
Therefore, print(getAgeCategory()) outputs 2 , which corresponds to option B .

Question #4


Which two assignments of a value to direction are allowed? (Choose 2.)

  • A. direction = .north
  • B. direction = direction.north
  • C. direction = north
  • D. direction = CompassPoint(north)
  • E. direction = CompassPoint.north

Which statement completes the code snippet so that:
* The lastReleaseDate remains the same when nextApplePhone.releaseDate is nil.
* The lastReleaseDate updates to the nextApplePhone.releaseDate when nextApplePhone.releaseDate is NOT nil.

  • A. lastReleaseDate : nextApplePhone.releaseDate
  • B. nextApplePhone.releaseDate! : lastReleaseDate
  • C. lastReleaseDate : nextApplcPhone.rcleaseDate!
  • D. nextApplePhone.releaseDate : lastReleaseDate
