golang中结构体的嵌套、方法的继承、方法的重写

package mainimport "fmt"type human struct {
name, phone string
age int8
}
type student struct {
human // 嵌套结构体
school string
}
type employee struct {
human
company string
}func (h human) sayHi() {
fmt.Printf("我叫%s,今年%d，联系方式%s\n", h.name, h.age, h.phone)
}
// 方法的重写
func (s student) sayHi() {
fmt.Printf("我叫%s,我是%s的,今年%d，联系方式%s\n", s.name, s.school, s.age, s.phone)
}func main() {
h1 := human{name: "zs", age: 18, phone: "1365434789"}
h1.sayHi()// 方法的继承
s1 := student{school: "一种", human: human{name: "lisi", age: 88, phone: "123456789"}}
s1.sayHi()}
