Kotlin - Variables and Type System

Identify the error in this Kotlin code snippet:

fun printLength(obj: Any) {
    if (obj is String) {
        println(obj.length())
    }
}

ANo error, code is correct

BMissing else block after if

CUsing parentheses with <code>length</code> property

DIncorrect use of <code>is</code> operator

Step-by-Step Solution

Solution:

Step 1: Check usage of length on String
In Kotlin, length is a property, not a function, so it should not have parentheses.
Step 2: Confirm other parts are correct
The is operator is used correctly and else block is optional.
Final Answer:
Using parentheses with length property -> Option C
Quick Check:
Property access no parentheses = D [OK]

Quick Trick: Remember: Kotlin properties have no parentheses [OK]
