A simple solution to the classic problem of the "producer-consumer" in Go.

consumer_producer.go

package main

import (
    "fmt"
    "math/rand"
)

const N_WORKERS = 10

func producer(c chan int) {
    c <- rand.Int()
}

func consumer(c chan int, done chan bool) {
    for {
        num := <-c
        fmt.Printf("Producer produced: %v\n", num)
        done <- true
    }
}

func main() {
    c := make(chan int)
    done := make(chan bool)
    for i := 0; i < N_WORKERS; i++ {
        go producer(c)
    }
    go consumer(c, done)
    for i := 0; i < N_WORKERS; i++ {
        <-done
    }
}
