====== 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

    fmt.Println(x, y, x + y)
}
</code>


===== Producer-consumer problem =====
<code go>
package main
 
import ("fmt")
 
var done = make(chan bool)
var cake = make(chan int)
 
func produce (firstname string) {
    for i := 0; i < 10; i++ {
        fmt.Printf("%s make cake %d\n", firstname, i)
        cake <- i
    }
    done <- true
}
 
func consume (firstname string) {
    for {
      cake_number := <-cake
      fmt.Printf("%s eat cake %d\n", firstname, cake_number)
   }
}
 
func main () {
   go produce("Alice")
   go consume("Bob")
   go consume("Maxime")
   <- done
}
</code>

===== Fork bomb =====
<code go>
package main

import "fmt"

func main() {
    c := make(chan bool)
    go func() {
        count := 0
        for <- c {
            count++
            fmt.Println(count)
        }
    }()
    bomb(c)
}

func bomb(tick chan bool) {
    for {
        tick <- true
        go bomb(tick)
    }
}
