Scala control flow program: Multiplication table using a for loop

Scala Control Flow Exercise-6 with Solution

Write a Scala program to print the multiplication table of a given number using a for loop.

Sample Solution:

Scala Code:

object MultiplicationTable {
  def main(args: Array[String]): Unit = {
    val number: Int = 5 // Number for which you want to print the multiplication table
    val tableSize: Int = 12 // Size of the multiplication table

    println(s"Multiplication Table of $number:")
    for (i <- 1 to tableSize) {
      val product = number * i
      println(s"$number * $i = $product")
    }
  }
}

Sample Output:

Multiplication Table of 5:
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50
5 * 11 = 55
5 * 12 = 60

Explanation:

In the above exercise -

First we define a variable "number" and assign it a value (5 in this case) for which we want to print the multiplication table. We also define a variable "tableSize" and assign it a value (12 in this case) which determines the size of the multiplication table.

We use a for loop to iterate from 1 to "tableSize". Inside the loop, we calculate the product of "number" and the current iteration value i and store it in the variable product. We then use println to display the multiplication expression and result.
