I just started practicing with channels, after writing to the channel,
nothing is output from there
func main() {
d := make(chan int)
go factorial(5, d)
time.Sleep(3 * time.Second)
}
func factorial(n int, d chan int) {
fmt.Println("function starting...")
time.Sleep(3 * time.Second)
var a int = 1
for ; n > 0; n-- {
a *= n
}
d <- a // //nothing works after that
fmt.Println(<-d)
fmt.Println(a)
}
--------------------------------------------------------------------------------------------------------------------------------------------
Another question I want to make a recursive function with a factorial, pass
it to goroutine in main. But I do not know if it is possible to somehow
combine *return* and a channel in the declaration of arguments.
---------------------------------------------------------------------------------------------------------------------------------------------
if I first pass in something to the channel from main,
a lock occurs.Why? So it's not possible at all?
