Challenge 2: Typed Values & Inference — Solution

fun main() {
    // With explicit type annotations
    val age: Int = 33
    val price: Double = 19.99
    val isReady: Boolean = true
    val initial: Char = 'P'
    val title: String = "Learning Blog"

    println(age)
    println(price)
    println(isReady)
    println(initial)
    println(title)

    // Same values, rewritten with type inference (no annotations)
    val inferredAge = 33
    val inferredPrice = 19.99
    val inferredIsReady = true
    val inferredInitial = 'P'
    val inferredTitle = "Learning Blog"

    println(inferredAge)
    println(inferredPrice)
    println(inferredIsReady)
    println(inferredInitial)
    println(inferredTitle)
}

/*
Output (both blocks print identically):
33
19.99
true
P
Learning Blog
33
19.99
true
P
Learning Blog

Notes:
- Int for whole numbers, Double for decimals, Boolean for true/false,
  Char for a single character (single quotes), String for text (double quotes).
- Kotlin infers the same types from the literals on the right-hand side —
  33 -> Int, 19.99 -> Double, true -> Boolean, 'P' -> Char, "..." -> String.
  The annotations are optional here because the type is unambiguous.
