func Filter(in <-chan int, out chan<- int, prime int) { for { i := <-in if i%prime != 0 { out <- i } } } func Generate(ch chan<- int) { for i := 2; ; i++ { ch <- i } } func main() { ch := make(chan int) go Generate(ch) // print the first 10 prime numbers for i := 0; i < 10; i++ { prime := <-ch println("next prime = ", prime) ch1 := make(chan int) go Filter(ch, ch1, prime) ch = ch1 } } func Filter(in <-chan int, out chan<- int, prime int) { for { i := <-in if i%prime != 0 { out <- i } } } func main() { ch := make(chan int) go func() { for i := 2; ; i++ { ch <- i } }() fori := 0; i < 10; i++ { prime := <-ch println("next prime = ", prime) ch1 := make(chan int) go Filter(ch, ch1, prime) ch = ch1 } } 运行后发现上面的代码可以实现并发素数筛的功能, 但是下面的闭包写法就不行, 有没有大佬解释一下?
