Struct

We can define a object and its attributes like this:

type person struct{
    name string
    age int
}

var P person
P.name = "CAO_Heng"
P.age = 25

Inside the function, you can also initialize the object like this:

P := person{"Tom",25}

Embeded segment

package main

import "fmt"

type Human struct{
    name string
    age int
    weight int
}

type Student struct{
    Human //Embeded segment, all elements in Human should be included here
    speciality string
}

You can also visit the embeded segments like this:

Mark.Human = Human{"Mark",55,220}
Maek.Human.age -= 1

A comprehensive example:

package main

import "fmt"

type Skill []string

type Human struct{
    name string
    age int
    weight int
}

type Student struct{
    Human    //string
    Skills    //self-defined slice
    int    //build-in type as the anonymous segment
    speciality string
}

func main(){
    jane := Student{Human:Human{"Jane",35,100},speciality:"Math"}

    jane.Skills = []string{anatomy}

    jane.Skills = append(jane.Skills,"physics","golang")

    jane.int = 3
}
