Milline on lingi või näitaja väärtus struktuuris, mis kasutab slice programmeerimiskeeles?

In Go, a slice is a structure that contains a pointer to an array, a length, and a capacity. When a slice is used inside a structure, the slice itself is stored as a value, but inside it, there is a pointer to the array data.

This means that when copying the structure, the slice is also copied, but both slices will point to the same data array. Changes made through one slice will be reflected in the other if they both point to the same array.

Example:

package main
import "fmt"

type MyStruct struct {
    Data []int
}

func main() {
    s1 := MyStruct{Data: []int{1, 2, 3}}
    s2 := s1 // copying the structure
    s2.Data[0] = 100
    fmt.Println(s1.Data) // Will print [100 2 3], as Data points to the same array
}

Therefore, the reference inside the slice within the structure points to a shared array, which is important to consider when copying and modifying data.
