我是golang的新手,我写了一个程序来测试io包：
@H_403_1@func main() {
readers := []io.Reader{
strings.NewReader("from string reader"),bytes.NewBufferString("from bytes reader"),}
reader := io.MultiReader(readers...)
data := make([]byte,1024)
var err error
//var n int
for err != io.EOF {
n,err := reader.Read(data)
fmt.Printf("%s\n",data[:n])
}
os.Exit(0)
}
