Hi,

If we omit an argument in a function call, Scala will take the default value we provided for it.

scala> def func(a:Int,b:Int=7){

| println(a*b)

| }

func: (a: Int, b: Int)Unit

scala> func(2,5)

10

scala> func(2)

But make sure that any default arguments must be after all non-default arguments.
