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

package main

import "fmt"

type rectangle struct {
	length  float64
	breadth float64
	color   string
}

func main() {
	var rect1 = rectangle{10, 20, "Green"}
	rect2 := rectangle{length: 20, breadth: 10, color: "Red"}

	if rect1 == rect2 {
		fmt.Println("True")
	} else {
		fmt.Println("False")
	}

	rect3 := new(rectangle)
	var rect4 = &rectangle{}

	if rect3 == rect4 {
		fmt.Println("True")
	} else {
		fmt.Println("False")
	}
}

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

package main

)
 
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)
