Functions continued

When two or more consecutive named function parameters share a type, you can omit the type from all but the last.

In this example, we shortened

x int, y int

to

x, y int

functions-continued.go

package main
import "fmt"
func add(x, y int) int {
    return x + y
}
func main() {
    fmt.Println(add(42, 13))
}
