[go-nuts] What goes wrong when embedding goroutines inside a for loop?

[Zhaoxun Yan]

package main
import "fmt"

func main() {
    targetIndice := make([]int, 3)
    targetIndice[0] = 5
    targetIndice[2] = 4
    
    for i,n := range targetIndice{
        fmt.Printf("%d : %d \n", i, n)
    }
    
    c := make(chan int)
    for i, n:= range targetIndice{
        go func(){
            fmt.Printf("targetIndice[%d]=%d \n", i, n)
            c <- 1
        }()
    }
    
    for i:=0; i<3; i++{
        <- c
    }
    
}

-----go run main.go---------
0 : 5 
1 : 0 
2 : 4 
targetIndice[2]=4 
targetIndice[2]=4 
targetIndice[2]=4
