Function dengan return multiple value memungkinkan output lebih dari 1 value.
package main
import (
"fmt"
)
func main() {
result1, result2 := sayHi("Dawam")
fmt.Println(result1, result2)
}
func sayHi(name string) (string, string) {
return fmt.Sprintf("Hi %s nice to meet you.", name), fmt.Sprintf("Welcome. ")
}
Hi Dawam nice to meet you. Welcome.
Contoh code 2 dengan mengabaikan 1 return value
package main
import (
"fmt"
)
func main() {
result1, _ := sayHi("Dawam")
fmt.Println(result1)
}
func sayHi(name string) (string, string) {
return fmt.Sprintf("Hi %s nice to meet you.", name), fmt.Sprintf("Welcome. ")
}
Hi Dawam nice to meet you.
package main
import "fmt"
func RectangleFormula(p, l int) (area int, parameter int) {
return p * l, 2 * (p + l)
}
func main() {
a, p := RectangleFormula(20, 30)
fmt.Println("Area :", a)
fmt.Println("Parameter:", p)
}
Area : 600
Parameter: 100
