Pointer to struct

Updated May 16, 20221 min readMarkdown

Struct fields can be accessed through a struct pointer.

To access the field Xof a struct when we have the struct pointer pwe could write(*p).X. However, that notation is cumbersome, so the language permits us instead to write just p.X, without the explicit dereference.

func main() {
    z := xy{1, 2}
    p := &z
    p.X = 20
    fmt.Println(z)
}

Go Program

package main

import "fmt"

type xy struct {
    X int
    Y int
}

func main() {
    z := xy{1, 2}
    p := &z
    p.X = 20
    fmt.Println(z)
}
