Kotlin - Operators and Expressions
Given the Kotlin expression:

Afalse
BSyntax error
Ctrue

Step-by-Step Solution
Solution:

  1. Step 1: Recall logical operator precedence

  2. Step 2: Evaluate all AND operations

    false && false = false, true && false = false.

  3. Step 3: Replace and evaluate OR operations left to right

    true || false || false = true || false = true.

  4. Final Answer:

    true -> Option C

  5. Quick Check:

    AND before OR, final result true [OK]
Quick Trick: Evaluate && before || in logical expressions [OK]
Common Mistakes:
MISTAKES
  • Evaluating OR before AND
