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

package main
 
import "fmt"
 
type rectangle struct {
	length  int
	breadth int
	color   string
 
	geometry struct {
		area      int
		perimeter int
	}
}
 
func main() {
	var rect rectangle // dot notation
	rect.length = 10
	rect.breadth = 20
	rect.color = "Green"
 
	rect.geometry.area = rect.length * rect.breadth
	rect.geometry.perimeter = 2 * (rect.length + rect.breadth)
 
	fmt.Println(rect)
	fmt.Println("Area:\t", rect.geometry.area)
	fmt.Println("Perimeter:", rect.geometry.perimeter)
}

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)
