Go language structures and methods

struct of use:

1 used to customize the complex data structure

2. struct which may comprise a plurality of fields (attributes)

3. struct type can be defined to distinguish between methods, attention and functions

4. struct type is a value type

5. struct type can be nested

6. Go language is not class type, only type struct

struct declaration:

type identifier {struct 
       field1 type 
       Field2 type 
} 

example: 
type struct {Student 
       the Name String 
       Age int 
Score int 
}

 struct field visit in: and other languages, the point of use

var stu Student

stu.Name = “tony”
stu.Age = 18
stu.Score=20

fmt.Printf(“name=%s age=%d score=%d”, stu.Name, stu.Age, stu.Score）

 struct defined three forms:

was stu Student 

was stu * Student = new (Student) 

was stu * Student = & Student {}

Wherein b and c are returned pointer to a structure, the following form of access

stu.Name, stu.Age and stu.Score or (* stu) .Name, (* stu) .Age like

 struct memory layout: struct all fields in the memory are continuous, the following layout:

struct list:

List definitions:

type Student struct {
       Name string
       Next   *Student
}

Each node contains the address of the next node, so that all the nodes of the string together, usually the first node in the list is called the list head
