A Tour of Go Pointers

2024-08-26 06:37:13

Go has pointers, but no pointer arithmetic.

Struct fields can be accessed through a struct pointer. The indirection through the pointer is transparent.

package main  

import "fmt"

type Vertex struct {

    X int

    Y int

}

func main() {

    p := Vertex{, }

    var q2 *Vertex = &p

    fmt.Println(q2.X)

    q := &p

    q.X = 1e9

    fmt.Println(p)

}
