[Golang]func的结构与特性整理-Part 2

二、特性

package mainimport ("fmt")func main() {  x, y := 1, 22  op := func(x, y int) int {    return x + y  }  fmt.Println(op(x,y))}

package mainimport ("fmt")type operate func(x, y int) int//Sum和operate的宣告方式一致func Sum(a, b int) int {  return a + b}func main() {  x, y := 1, 22  var op operate  op = Sum //把Sum函数赋给operate类型的变数op  fmt.Println(op(x,y))}
