Go struct

Go does not have class, struct plays similar role as class in other languages

Go struct definition

type ABC struct {
	name   string
	number int
}

Go struct init

a := ABC{}
a.name = "Nyannyan"
a.number = 1

c := ABC{
   "Mon",
   3,
}

d := new(ABC)
d.name = "Sansan"
d.number = 4

p := &amp;ABC{"Pin", 5}

Go struct embed

Struct in struct. It’s like extend

type ABC struct {
	name   string
	number int
}

type ExABC struct {
	ext int
	ABC
}

ext := ExABC{1, ABC{"Boo", 2}}

Full example

package main

import (
	"fmt"
)

type ABC struct {
	name   string
	number int
}

type ExABC struct {
	ext int
	ABC
}

func main() {
	a := ABC{}
	a.name = "Nyannyan"
	a.number = 1
	fmt.Println(a.name)

	c := ABC{
		"Mon",
		3,
	}

	d := new(ABC)
	d.name = "Sansan"
	d.number = 4

	p := &amp;ABC{"Pin", 5}

	fmt.Println(a)
	fmt.Println(c)
	fmt.Println(d)
	fmt.Println(p)

	ext := ExABC{1, ABC{"Boo", 2}}
	fmt.Println(ext)

	var instruct struct {
		name   string
		number int
	}

	instruct.name = "Gok"
	instruct.number = 5

	fmt.Println(instruct)
}
