Example 1: how to make struct type as array in go

package main
 
import (
    "fmt"
    "encoding/json"
)
 
type Employee struct {
    FirstName  string `json:"firstname"`
    LastName   string `json:"lastname"`
    City string `json:"city"`
}
 
func main() {
    json_string := `
    {
        "firstname": "Rocky",
        "lastname": "Sting",
        "city": "London"
    }`
 
    emp1 := new(Employee)
    json.Unmarshal([]byte(json_string), emp1)
    fmt.Println(emp1)
 
    emp2 := new(Employee)
    emp2.FirstName = "Ramesh"
    emp2.LastName = "Soni"
    emp2.City = "Mumbai"
    jsonStr, _ := json.Marshal(emp2)
    fmt.Printf("%s\n", jsonStr)
}

Example 2: how to make struct type as array in go

package main
 
import "fmt"
 
type rectangle struct {
	length  int
	breadth int
	color   string
}
 
func main() {
	rect1 := new(rectangle) // rect1 is a pointer to an instance of rectangle
	rect1.length = 10
	rect1.breadth = 20
	rect1.color = "Green"
	fmt.Println(rect1)
 
	var rect2 = new(rectangle) // rect2 is an instance of rectangle
	rect2.length = 10
	rect2.color = "Red"
	fmt.Println(rect2)
