Go‘s structs are typed collections of fields. They‘re useful for grouping data together to form records
package main import ( "fmt" ) type person struct { name string age int } func main() { fmt.Println(person{"Bob", 20}) fmt.Println(person{name: "Alice", age: 30}) fmt.Println(person{name: "Fred"}) fmt.Println(&person{name: "Ann", age: 40}) s := person{name: "Sean", age: 50} fmt.Println(s.name) sp := &s fmt.Println(sp.age) sp.age = 51 fmt.Println(sp.age) }
{Bob 20}
{Alice 30}
{Fred 0}
&{Ann 40}
Sean
50
总结 :
1 : 通过 & 能得出 struct 的指针
2 : You can also use dots with struct pointers - the pointers are automatically dereferenced
