// Go has built-in support for multiple return values.
// This feature is used often in idiomatic Go, for example
// to return both result and error values from a function.

package main

import "fmt"

// The `(int, int)` in this signature shows that the
// function returns 2 ints.
func vals() (int, int) {
    return 3, 7
}

func main() {
    // Here we use the 2 different return values from the
    // call, i.e. perform multiple assignement.
    a, b := vals()
    fmt.Println(a)
    fmt.Println(b)

    // In cases were you only want a subset of the
    // returned values, use the blank identifier `_`.
    _, c := vals()
    fmt.Println(c)
