Golang学习笔记-结构体

定义结构体的格式如下：

type struct_variable_type struct {
   member definition;
   member definition;
   ...
   member definition;
}

type Book struct {
    id int
    name string
    author string
}

初始化结构体的格式如下，使用key-value的形式初始化时忽略的字段为零值。

structure_variable_type {value1, value2...valuen}
structure_variable_type { key1: value1, key2: value2..., keyn: valuen}

func main() {
    fmt.Println(Book{1,"clean code","xiongya"})//{1 clean code xiongya}
    fmt.Println(Book{id:100,author:"xiongya",name:"clean code"})//{100 clean code xiongya}
    fmt.Println(Book{author:"xiongya",name:"clean code"})//{0 clean code xiongya}
}

不管结构体还是结构体指针，都使用.来访问结构体成员。

func main() {
    book:=Book{1,"clean code","xiongya"}
    bookPointer:=&book
    fmt.Println(book.name)
    fmt.Println(bookPointer.author)
}
