遇到了， 小程式來練練手：

package main 
import "fmt"

type Base struct {
	bx int
	by int
}

type Student struct {
	b Base
	x int
	y int
}

func main() {
	s := new(Student)
	s.b.bx = 1
	s.b.by = 100
	s.x = 2
	s.y = 3

	s1 := Student{Base{1, 100}, 2, 3}

	fmt.Println(s, s1)
}

        結果：&{{1 100} 2 3} {{1 100} 2 3}

        稍作修改：

package main 
import "fmt"

type Base struct {
	bx int
	by int
}

type Student struct {
	Base
	x int
	y int
}

func main() {
	s := new(Student)
	s.bx = 1
	s.by = 100
	s.x = 2
	s.y = 3

	s1 := Student{Base{1, 100}, 2, 3}
	fmt.Println(s, s1)
}
 

       結果：&{{1 100} 2 3} {{1 100} 2 3}

       不多說。
