Consider this Kotlin code:
fun isPositive(n: Int) = n > 0
println(isPositive(-3))

What is the output?
Atrue
Bnull
CCompilation error
Dfalse

  1. Step 1: Understand the function logic

    The function returns true if n is greater than 0, otherwise false.

  2. Step 2: Evaluate for input -3

    -3 is not greater than 0, so the function returns false, which is printed.

  3. Final Answer:

    false -> Option D

  4. Quick Check:

    isPositive(-3) = false [OK]
Quick Trick: Check if number > 0 returns true else false [OK]
Common Mistakes:
MISTAKES
  • Assuming negative numbers return true
  • Confusing boolean output with string
  • Expecting compilation error
