How to iterate through each character of a string in Golang?

How to iterate through each character of a string in Golang?

In Golang, strings are actually composed of bytes, and each character may be represented by multiple bytes. Therefore, to iterate over each character of a string, we need to first convert the string into a rune slice. rune is a data type in the Go language that is used to represent Unicode characters.

Next, I will introduce the method of string traversal using Go language and provide code examples.

First, we define a string containing Chinese characters:

package main

import (
    "fmt"
)

func main() {
    str := "你好,世界!"
    runes := []rune(str)

    for i := 0; i < len(runes); i++ {
        fmt.Printf("%c ", runes[i])
    }
}
Copy after login

In this code, we first convert the string "Hello, world!" into a rune slice. Then, we use a for loop to traverse the rune slice and output each character through the fmt.Printf("%c ", runes[i]) statement.

When we run this code, the output is:

你 好 , 世 界 !
Copy after login

With the above example, we successfully iterated through the string containing Chinese characters and output each character. In Golang, this method is a relatively simple and efficient way to traverse strings. I hope this article is helpful to you, thank you for reading!
