Go language producer, consumer case

This is a creation in Article, where the information may have evolved or changed.

Package Mainimport "FMT" import "Time" Func main () {        //ch: = Make (chan int, ten)        ch: = make (chan int)        go produce ("Producer 1", CH)        Go Produce ("Producer 2", CH) time        . Sleep (1 * time. Second)        go use (CH) time        . Sleep (101 * time. Second)}func Produce (pname string,ch Chan int) {for        i:= 0;i < 20;i++ {                FMT. PRINTLN ("Produce", PName, ":", i)                ch <-I//here need to be printed after the statement, no person may produce an understanding ambiguity time                . Sleep (1 * time. Second)        }}func use (ch chan int) {        var i int        loop1:        i = <-ch        fmt. Println ("Use:", i)        Goto LOOP1}

The above code has many details on the imperfect place, modified:

Package Mainimport "FMT" import "Time" Func main () {        //ch: = Make (chan int, ten)        ch: = make (chan int)        defer clos E (CH)        go Produce ("Producer 1", ch)        go Produce ("Producer 2", CH) time        . Sleep (1 * time. Second)        go use (CH) time        . Sleep (* time. Second)}func Produce (pname string,ch Chan int) {for        i:= 0;i < 20;i++ {                FMT. PRINTLN ("Produce", PName, ":", i)                ch <-i time                . Sleep (1 * time. Second)        }}func use (ch Chan int) {for        i: = Range ch {                FMT. Println ("Use:", i)        }}

Multiple producers, multiple consumers

Package Mainimport "FMT" import "Time" Func main () {        //ch: = Make (chan int, ten)        ch: = make (chan int)        defer clos E (CH)        go Produce ("Producer 1", ch)        go Produce ("Producer 2", CH) time        . Sleep (1 * time. Second)        Go Use ("Consumer 1", ch)        go Use ("Consumer 2", ch) time        . Sleep (* time. Second)}func Produce (pname string, ch Chan int) {for        I: = 0; i <; i++ {                fmt. PRINTLN ("Produce", PName, ":", i)                ch <-i time                . Sleep (1 * time. Second)        }}func Use (uname string, ch Chan int) {for        i: = Range ch {                FMT. PRINTLN ("Use", Uname, ":", I)        }}
