Problem Statement

Create a function which takes in a number of arguments which are specified by name rather than (necessarily) position, and show how to call the function. If the language supports reordering the arguments or optionally omitting some of them, note this. Note: See also:

Let's start with the solution:

def add(x: Int, y: Int = 1) = x + y


scala> add(5)
6

scala> add(y=10, x=4)
14
