详见代码块。
```
package main
import (
"fmt"
)
func GenerateNatural() chan int {
ch := make(chan int)
go func() {
for i := 2; ; i++ {
fmt.Println("GenerateNatural", i)
ch <- i
}
}()
return ch
}
func PrimeFilter(in <-chan int, prime int) chan int {
out := make(chan int)
go func() {
for {
fmt.Println()
if i := <-in; i%prime != 0 {
out <- i
}
}
}()
return out
}
func main() {
ch := GenerateNatural()
for i := 0; i < 100; i++ {
prime := <-ch
fmt.Printf("%v:%v\n", i+1, prime)
ch = PrimeFilter(ch, prime)
}
}
```
