struct结构体传值

结构体是值传递

type Person struct {
    Name string
}

func TestStruct(t *testing.T) {
    var p = Person{
        Name: "jack",
    }
    fmt.Printf("%p %s \n", &p, p.Name)
    P(p)
    fmt.Printf("%p %s \n", &p, p.Name)
}

func P(p Person) {
    p.Name = "rose"
    fmt.Printf("P %p\n", &p)
}

输出结果

0xc000098fa0 jack 
P 0xc000098fc0
0xc000098fa0 jack 

指向不同的变量
