package fmt
Scan scans text read from standard input, storing successive space-separated values into successive arguments. Newlines count as space. It returns the number of items successfully scanned. If that is less than the number of arguments, err will report why.

go func() {
var o string
fmt.Scan(&o)
c <- o
}()
Example 3:
...
var (
readValue string

err = errors.New("Can't read input")
