A brief discussion on strings and arrays in Go language

package main
import "fmt"
var name string                                                                                                                             �
var empty name string = "" //Declare an empty string
func main() {
//Declare multiple strings and assign values
 a, b, v := "hello", "word", "widuu"
 (a, b, v)
//Convert the content of the string, first convert the type of a to []byte
 c := []byte(a)
//Assignment
 c[0] = 'n'
// When converting to string type, we actually found that our a has not changed
//But a new string change
 d := string(c)
 (d)
//Stand prototype output
 m := `hello
   word`
 (m)
}

package main
import "fmt"
var arr [2]int //Declare an array
func main() {
arr[0] = 1 //Array assignment
 (arr)
arrtest := [3]int{1, 2, 3} //Another way to declare arrays
 (arrtest)
a := [...]int{1, 2} //[...] Automatically identify the length of the array
 (a)
(len(a))//The length of the output array
}

package main
import "fmt"
func main() {
d := []int{1, 2, 3} //Declare a slice, which is a dynamic array, has no length
 (d)
 var q, w []int
q = d[0:1] //The length above can be determined
 w = d[1:3]
d = append(d, 2) //Add elements to it
 (d)
 (q, w)
}
