Golang : Return multiple values from function
One of the features that I like about Golang is the ability to return multiple values from a function (Python and Perl can do that as well).
In this short tutorial, we will explore how to create a function that return multiple values.
To return more than one value, we just add another return parameter. For example, (int int)
means that the function is expected to return 2 integer values.
func returnTwoValues(a, b int) (int, int)
This code will demonstrate just that :
package main
import (
"fmt"
)
func returnTwoValues(a, b int) (int, int) {
return a + b, a - b
}
func main() {
a := 10
b := 8
aPlusB, aMinusB := returnTwoValues(a, b)
fmt.Printf("A is %d and B is %d \n", a, b)
fmt.Printf("A Plus B : %d and A Minus B : %d \n", aPlusB, aMinusB)
}
output :
A is 10 and B is 8
A Plus B : 18 and A Minus B : 2
