Looping through an array using indices in Scala in Scala

In some instances, we will want to loop through an array using indices.

The indices of an array meals are all the integer values from 0 to meals.length - 1, so we can iterate over them using an index variable i:

val meals = Array("pancakes", "pasta", "pizza", "avocado")

for (i <- meals.indices) {
	println("Meal number " + (i + 1) + " is " + meals(i) + ".")
}

The output of this code is:

Meal number 1 is pancakes.
Meal number 2 is pasta.
Meal number 3 is pizza.
Meal number 4 is avocado.

Assignment
