Scala Power Calculator: Calculate the Power of a Number

Scala Function Exercise-7 with Solution

Write a Scala function to calculate the power of a number.

Sample Solution:

Scala Code:

object PowerCalculator {
  def calculatePower(base: Double, exponent: Int): Double = {
    var result = 1.0
    var i = 0

    while (i < exponent) {
      result *= base
      i += 1
    }

    result
  }

  def main(args: Array[String]): Unit = {
    val base = 3.0
    val exponent = 4
    val result = calculatePower(base, exponent)
    println(s"The result of $base raised to the power of $exponent is: $result")
  }
}

Sample Output:

The result of 3.0 raised to the power of 4 is: 81.0
