Chan Array Initialization

package mainimport "fmt"func run() {    chann[0] <- 1}var chann = make([]chan int, 2)func main() {    go run()    obj := <- chann[0]    fmt.Println(obj)}

Out:fatal Error:all Goroutines is asleep-deadlock!

If you watch with Fswatch, you can only find that it is blocked, without this information.

The cause of the problem:

var Chann = make ([]chan int, 2) Simply initializes the Chan array, but each Chan in the array is not initialized with a value of nil. It is not possible to write or read data in the channel variable at this time.

The correct initialization method:

var int {   int      ), int), int),     int),int),}  var chans [5int      for I: = range Chans {   int)}
