How do I modify the "println" statement to accept a variable "person" using string interpolation to print "Hello Tom"

It says to assign "Tom" to the variable "person" and modify the println statement and I've been stuck for a while now. Thank you.

parameters.swift
func greeting(person: String) {
    println("Hello" \())
}
greeting()

1 Answer

The parameter person should be included inside the quotes, and Tom is passed to greeting's person parameter.

parameters.swift
func greeting(person: String) {
    println("Hello \(person)")
}
greeting("Tom")

Thank you so much Daniel. Really appreciated.
