Struct Fields

Access struct fields with a dot. Read them, write them — same syntax either way.

Try it: Change v.X = 4 to a different value and see the output update.

main.go ▶ Run in Playground 
package main

import "fmt"

type Vertex struct {
	X int
	Y int
}

func main() {
	v := Vertex{1, 2}
	v.X = 4
	fmt.Println(v.X)
}
