将模型外包到自己的程序包中时，如何访问变量

Hi guys and thanks in advance for your help! :)

I try to learn Go and wanna ask how I can access a variable defined in a struct in an own class. How do you make your models in go? I really wanna put the models in a own class.

When I do this I cant access the Variables of my struct Student.

package main

import (
    "fmt"
    "github.com/nikolastankovic/hello/models"
)

func main() {
    var nikola models.Student
    nikola.name = "nikola" // THIS DOESN'T WORK :(
    fmt.Println(nikola)
}

Model Student in subpackage models:

package models

type Student struct {
    name string
    number int
}

You need to write the attribute name with a capital letter N and it will work. Like this:

package models

type Student struct {
    Name string
    Number int
}

Small letter means unexported (private) in Go and capital letter means exported (public).
