您還必須使用strconv來轉(zhuǎn)換數(shù)字
scn := bufio.NewScanner(os.Stdin)
scn.Scan()
n1, err := strconv.Atoi(scn.Text())
if err != nil {
fmt.Printf("operation failed: %v\n", err)
return
}
scn.Scan()
n2, err := strconv.Atoi(scn.Text())
if err != nil {
fmt.Printf("operation failed: %v\n", err)
return
}
fmt.Printf("%d + %d = %d\n", n1, n2, n1+n2)
