Creating Instances of Struct Types
The var keyword initializes a variable rect. Using dot notation, values are assigned to the struct fields.
Example
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)
}
