What does the program print (lines separated by spaces)?

KOTLIN

fun main() {
    val word = "cat"
    println(word[0])
    println(word[0] + 1)
}

c d

Expecting c c1: treating word[0] as a string. It is a Char, and adding 1 to a Char gives the next character, 'd'.
Expecting c 100: thinking a Char turns into its number. 'c' + 1 is still a Char; its code is read with .code.
