In this article, the editor introduces in detail "how to extract strings one by one in go language". The content is detailed, the steps are clear, and the details are handled properly. I hope this article "how to extract strings in go language one by one" can help you solve your doubts.

Go language traverses strings-- gets each string element

Traverse every ASCII character

Traversing ASCII characters traverses using for's numeric loop, directly fetching the subscript of each string to get ASCII characters, as shown in the following example.

Package mainimport "fmt" func main () {theme: = "hello" for I: = 0; I < len (theme); iTunes + {fmt.Printf ("ascii:% c% d\ n", theme [I], theme [I])}}

The program output is as follows:

Ascii: h 104ascii: e 101ascii: l 108ascii: l 108ascii: O 111ascii: 32ascii: P 112ascii: h 104ascii: P 112ascii: ä 228ascii:, 184ascii: ­173ascii: æ 230ascii: 150ascii: 135ascii: ç 231ascii: 189ascii: â 145

The Chinese characters obtained in this mode are "miserable". Because Unicode is not used, Chinese characters are displayed as garbled.

Traversing strings by Unicode character

The same content:

Package mainimport "fmt" func main () {theme: = "hello" for _, s: = range theme {fmt.Printf ("Unicode:% c% d\ n", s, s)}}

The program output is as follows:
