ParametersReturns.scala

object Main {
  def area(width: Int, height: Int): Int = {
    width * height
  }

  def main(args: Array[String]): Unit = {
    val width = 
    val height = 4
    val result = area(width, height)

    println("width=" + width)
    println("height=" + height)
    println("area=" + result)
  }
}

object Main {
  def area(width: Int, height: Int): Int = {
    width * height
  }

  def main(args: Array[String]): Unit = {
    val width = 
    val height = 4
    val result = area(width, height)

    println("width=" + width)
    println("height=" + height)
    println("area=" + result)
  }
}

parameters-returns Parameters carry values into a method. The return value carries the result back to the caller.
