翠花，上代码

package main

import (
    "bufio"
    "fmt"
    "os"
    "strings"
)

func main() {
    //从标准输入读取数据
    inputReader := bufio.NewReader(os.Stdin)
    fmt.Println("Please input your name：")
    //读取数据直到遇见\n位置
    input, err := inputReader.ReadString(‘\n‘)
    if err != nil {
        fmt.Printf("An error occurred:%s\n", err)
        //异常错误后退出
        os.Exit(1)

    } else {
        //用切片操作删除最后的\n
        name := input[:len(input)-1]
        fmt.Printf("Hello,%s!What can i di for you?\n", name)
    }
    for {
        input, err = inputReader.ReadString(‘\n‘)
        if err != nil {
            fmt.Printf("An error occurred:%s\n", err)
            continue
        }
        input = input[:len(input)-1]
        //全部转换为小写
        input = strings.ToLower(input)
        switch input {
        case "":
            continue
        case "nothing", "bye":
            fmt.Println("Bye!")
            //正常退出
            os.Exit(0)
        default:

        }
