What are some advanced examples of using pointers in Go?

Can you explain some advanced examples of using pointers in Go?

Sure! One advanced example is using pointers to modify a struct's fields directly. Would you like to see a code snippet?

Yes, please provide a code snippet.

Here's a simple example:

package main
import "fmt"

type Person struct {
    Name string
    Age  int
}

func updateAge(p *Person, newAge int) {
    p.Age = newAge
}

func main() {
    john := Person{Name: "John", Age: 30}
    updateAge(&john, 31)
    fmt.Println(john)
}

This code updates the age of a person using a pointer.

That's great! Are there any other advanced use cases for pointers?

Absolutely! Another use case is implementing linked lists or trees, where nodes reference each other using pointers.
