Which of the following is the correct way to get the Unicode code of a Char in Kotlin?
Aval code = 'A'.code
Bval code = 'A'.unicodeValue()
Cval code = 'A'.toInt()
Dval code = 'A'.unicode
Step-by-Step Solution
Solution:

  1. Step 1: Recall Kotlin Char Unicode property

    Kotlin provides the code property to get the Unicode integer value of a Char.

  2. Step 2: Evaluate options

    val code = 'A'.code uses code property correctly. val code = 'A'.toInt() uses toInt() which does not exist for Char. Options B and D use non-existent methods/properties.

  3. Final Answer:

    val code = 'A'.code -> Option A

  4. Quick Check:

    Use .code to get Unicode number [OK]
