Go语言产生素数

package main

// 生成2, 3, 4, ... 到 channel 'ch'中.

func Generate(ch chan<- int) {

for i := 2; ; i++ {

ch <- i // Send 'i' to channel 'ch'.

}

}

// 从管道复制值 'in' 到 channel 'out',

// 移除可整除的数 'prime'.

func Filter(in <-chan int, out chan<- int, prime int) {

for {

i := <-in // 接收值 'in'.

if i%prime != 0 {

out <- i // 传入 'i' 到 'out'.

}

}

}

func main() {

ch := make(chan int) // Create a newchannel.

go Generate(ch) // Launch Generate goroutine.

for i := 0; i < 10; i++ {

prime := <-ch

print(prime, "\n")

ch1 := make(chan int)

go Filter(ch, ch1, prime)

ch = ch1

}

}
