Learning Go

Simple examples

Sum the elements of a list

<code go> package main import “fmt”

func sum(a []int, c chan int) {

  sum := 0
  for _, v := range a {
      sum += v
  }
  c <- sum  // send sum to c

}

func main() {

  a := []int{7, 2, 8, -9, 4, 0}
      c := make(chan int)
  go sum(a[:len(a)/2], c)
  go sum(a[len(a)/2:], c)
      x, y := <-c, <-c  // receive from c
  fmt.Println(x, y, x + y)

} </go>
