Challenge 1: Inspecting a Class with KClass — Solution

import kotlin.reflect.full.memberProperties

data class Product(val name: String, val price: Double, val inStock: Boolean)

fun describe(obj: Any) {
    for (prop in obj::class.memberProperties) {
        println("${prop.name}: ${prop.getter.call(obj)}")
    }
}

fun main() {
    val product = Product("Keyboard", 49.99, true)
    describe(product)
}

/*
Output:
name: Keyboard
price: 49.99
inStock: true

Notes:
- obj::class.memberProperties (from kotlin.reflect.full, part of the
  kotlin-reflect library) returns every property declared on the
  object's actual runtime class.
- prop.getter.call(obj) invokes that specific property's getter on the
  given instance, returning its value generically as Any?.
- describe() works for ANY object passed to it, not just Product — it
  never references "name", "price", or "inStock" by name directly, which
  is the whole point of doing this via reflection instead of hardcoding
  three println() calls.
