Closures Functions in Golang
Closures are a special case of anonymous functions. Closures are anonymous functions which access the variables defined outside the body of the function.
Example
Anonymous function accessing the variable defined outside body.
package main
import "fmt"
func main() {
l := 20
b := 30
func() {
var area int
area = l * b
fmt.Println(area)
}()
}
Example
Anonymous function accessing variable on each iteration of loop inside function body.
package main
import "fmt"
func main() {
for i := 10.0; i < 100; i += 10.0 {
rad := func() float64 {
return i * 39.370
}()
fmt.Printf("%.2f Meter = %.2f Inch\n", i, rad)
}
}
