【Go 语言社区】解析Go语言编程中的struct结构

package main
import "fmt"
type Person struct {
 Age  int
 Name string
}
func main() {
 //初始化两种
 a := Person{}
 a.Age = 2
 a.Name = "widuu"
 fmt.Println(a)
 b := Person{
  Age:  24,
  Name: "widuu",
 }
 fmt.Println(b)
}
go指针操作
如下我们要对数值进行改变，先要取内存地址，然后再内存地址上改变他的引用
package main
import "fmt"
type Person struct {
 Age  int
 Name string
}
func main() {
 b := &Person{
  Age:  24,
  Name: "widuu",
 }
 fmt.Println(b)
 G(b)
 fmt.Println(b)
}
func G(per *Person) {
 per.Age = 15
 fmt.Println(per)
}

 func main() {
  a := struct {
   name string
   Age  int
  }{
   name: "widuu",
   Age:  19,
  }
  fmt.Println(a)
}
package main
import "fmt"
type Person struct {
 Age    int
 Name   string
 Member struct {
  phone, City string
 }
}
func main() {
 a := Person{Age: 16, Name: "widuu"}
 a.Member.phone = "13800000"
 a.Member.City = "widuuweb"
 fmt.Println(a)
}
（2）匿名类值不需要数据名称、在赋值的时候两个结构必须是一样的
package main
import "fmt"
type Person struct {
 string
 int
}
func main() {
 a := Person{"joe", 19}
 var b Person
 b = a
 fmt.Println(b)
}

package main
import "fmt"
type Person struct {
 Name string
 Age  int
}
type student struct {
 Person
 work string
}
func main() {
//实例化时 如果嵌入式的结构没有数据结构的名字 就默认是类型名字Person:Person
 a := student{Person: Person{Name: "widuu", Age: 19}, work: "IT"}
 fmt.Println(a)
}

package main
import "fmt"
type A struct {
 Name string  //这个是共有的大写 如果是小写的name就包内可以用私有的
}
type B struct {
 Name string
}
func main() {
 a := A{}
 b := B{}
 a.print()
 b.print()
}
//通过type不同，来取相同的方法的名称
func (a *A) print() {
 fmt.Println("A")
}
func (b *B) print() {
 fmt.Println("B")
}
