Go Struct

A struct is a collection of fields. Struct fields are accessed using a dot. (Docs)

package main

import "fmt"

type Person struct {
  sex string
  age int
}

func main() {
  // declare Person struct
  me := Person{"Male", 22}
  fmt.Printf("I'm %d years old %s", me.age, me.sex)

  // declaring 'newborn',
  // age:0 is implicit (int defaults to 0)
  me = Person{sex: "Male"}
  fmt.Printf("\nI'm %d year old %s", me.age, me.sex)
}
