• How to broadcast message using channel 5 answers

I know if once get the data from a channel that data won't receive from any other place that channel is waiting. However, if I want to design a program broadcast that channel has got data and It is ready to take out in different places without affecting other channels but in all places, I need to receive data in the same order, what will be the best design?

As a example:

func sender(c chan int){
c-> 5
}

func reciever1(c chan int){
 i:= <-c
...
}

func reciever2(c chan int){
 i:= <-c
...
}

Here when executing both reciever1() and reciver2() Both should get same result.

You have to create multiple channels and pass the same value to each of those channels. Example

package main
import (
    "fmt"
)

func main(){
    chann1 := make(chan int)
    chann2 := make(chan int)
    go func(){
        for {
            val :=<- chann1
            fmt.Println("GORoutine 1", val)
        }

    }()
    go func(){
        for {
            val :=<- chann2
            fmt.Println("GORoutine 2", val)
        }

    }()

    for i:=0;i<=10;i++{
        chann1 <- i
        chann2 <- i
    }


}
