How to do it...

Another step forward to reduce the number of overloads and increase code readability is to use named arguments. Let's take look at the following code:

1. Taking the same example of the foo function, here's how we can use named arguments:

fun main(args: Array<String>) {     foo(b=0.9)     foo(a=1,c="Custom string")} fun foo(a:Int=0, b: Double =0.0, c:String="some default value"){     println("a=$a , b=$b ,c = $c")}

2. This is the output that you will get by running the preceding code:

Output:a=0 , b=0.9 ,c = some default valuea=1 , b=0.0 ,c = Custom string

3. The named arguments prevent us from overloads and also make our code much more readable. Also, we don't need to put in all the arguments. What I mean is, if you just had two parameters— ...
