Adding function parameters

Earlier, we saw a basic example of adding a parameter to a function:

fun helloFunctions(greeting: String) {
 println("$greeting Kotlin Functions")
}

Parameters can be added after a function name using the Pascal notation of name: Type. Passing an argument to a function works the same as in Java:

fun main(args: Array<String>) {
    helloFunctions("Hello!")
}

Functions with a single parameter would be quite limited, and, thankfully, we can add multiple parameters to our functions as needed.
