Go 创建字符串

package main



import "fmt"



func main() {

   var greeting =  "Hello world!"



   fmt.Printf("normal string: ")

   fmt.Printf("%s", greeting)

   fmt.Printf("\n")

   fmt.Printf("hex bytes: ")



   for i := 0; i < len(greeting); i++ {

       fmt.Printf("%x ", greeting[i])

   }

   fmt.Printf("\n")



   const sampleText = "\xbd\xb2\x3d\xbc\x20\xe2\x8c\x98"

   /*q flag escapes unprintable characters, with + flag it escapses non-ascii

   characters as well to make output unambigous  

   */

   fmt.Printf("quoted string: ")

   fmt.Printf("%+q", sampleText)

   fmt.Printf("\n")
