type Person struct {
    Name string
    Age  int
}

func updatePerson(p *Person) {
    p.Name = "Alice"
    p.Age = 30
}

func main() {
    person := Person{Name: "Bob", Age: 25}
    updatePerson(&person)
    // person 现在是 {Name: "Alice", Age: 30}
}

func (p *Person) SetName(name string) {
    p.Name = name
}

func main() {
    person := &Person{Name: "Tom"}
    person.SetName("Jerry") // 正确修改原始值
}
