Go by Example: Structs

Go’s structs are typed collections of fields. They’re useful for grouping data together to form records.
	package main
	import "fmt"
This `person` struct type has `name` and `age` fields.	type person struct { name string age int }
	func main() {
This syntax creates a new struct.	fmt.Println(person{"Bob", 20})
You can name the fields when initializing a struct.	fmt.Println(person{name: "Alice", age: 30})
Omitted fields will be zero-valued.	fmt.Println(person{name: "Fred"})
An `&` prefix yields a pointer to the struct.	fmt.Println(&person{name: "Ann", age: 40})
Access struct fields with a dot.	s := person{name: "Sean", age: 50} fmt.Println(s.name)
You can also use dots with struct pointers - the pointers are automatically dereferenced.	sp := &s fmt.Println(sp.age)
Structs are mutable.	sp.age = 51 fmt.Println(sp.age) }

$ go run structs.go
{Bob 20}
{Alice 30}
{Fred 0}
&{Ann 40}
Sean
50
51
