bufio.NewReader总是创建一个新行:/

I use this, to collect a input and display the input then, but when I do it like this the "something" text will be displayed in a new line, but I want the text to be displayed in the same line, any ideas?

func main() {
    fmt.Println("Example")
    print("example: ")
    in := bufio.NewReader(os.Stdin); 
    input, err := in.ReadString('
');
    if err != nil {
        fmt.Println("Error: ", err)
    }

    fmt.Println(input, "something")
}

    fmt.Println() automatically appends a newline to the end of it's output.

    You could try using Printf, which takes a "format string" and a list of inputs.

    An example would be:

    func main() {
      fmt.Println("Example")
      print("example: ")
      in := bufio.NewReader(os.Stdin); 
      input, err := in.ReadString('
    ');
      if err != nil {
          fmt.Println("Error: ", err)
      }
    
      fmt.Printf("something : %s", input)
    }
    

    In this case, %s is a placeholder for a string type. All the placeholders can be found in the fmt godoc: http://golang.org/pkg/fmt/

    Also if the input itself has a newline at the end, you can use Trim from the package strings to pull off the character.
