Kotlin - Loops and Ranges

Which of the following is the correct way to print both index and value from a list names using withIndex() in Kotlin?

Afor (i in names) { println(i) }

Bfor (name in names.withIndex()) { println(name) }

Cfor ((i, name) in names.withIndex()) { println("$i: $name") }

Dfor (i in names.indices) { println(names[i]) }

Step-by-Step Solution

Solution:

Step 1: Identify correct destructuring syntax
The correct syntax to get index and value is for ((i, name) in names.withIndex()).
Step 2: Confirm print format
Inside the loop, printing "$i: $name" shows index and value clearly.
Final Answer:
for ((i, name) in names.withIndex()) { println("$i: $name") } -> Option C
Quick Check:
Destructuring with withIndex() = for ((i, name) in names.withIndex()) { println("$i: $name") } [OK]

Quick Trick: Use (index, value) to destructure withIndex() pairs [OK]
