A structure is a collection of data fields with declared data types. Golang can declare and create its data types by combining one or more types, including both built-in and user-defined types.

package main
import "fmt"

type student struct {
    Name    string
    class   string
    Roll_No int
    Marks   int
}

func main() {
    var s1 = student{"Sandeep", "X", 2001, 98}
    var s2 student
    s2.Name = "Sonu"
    s2.class = "IX"
    s2.Roll_No = 2039
    s2.Marks = 56
    fmt.Println(s1)
    fmt.Println(s2)
}
