Go语言结构体

Go语言结构体

Go语言结构体的基本语法

type Book struct {
	BOOK_NAME string
	ANTHOR string
	SUBJECT string
	BOOK_ID int64
}

结构体作为参数

func PrintBooK(BookEntity  Book ) (){
 
  fmt.Printf("%v\n", BookEntity.BOOK_NAME)
 
  fmt.Printf("%v\n", BookEntity.ANTHOR)
 
  fmt.Printf("%v\n", BookEntity.SUBJECT)
 
  fmt.Printf("%v\n", BookEntity.BOOK_ID)
 
}

结构体的使用

package main
import "fmt"
func main() {
	var person Person //定义一个person的变量
 
	person.name = "张三"
	person.age = 18
	person.height = 173
	person.weight = 53
	person.hobby = "学习"
	fmt.Printf("person.name=%v\n", person.name)
	fmt.Printf("person.age=%v\n", person.age)
	fmt.Printf("person.height=%v\n", person.height)
	fmt.Printf("person.weight=%v\n", person.weight)
	fmt.Printf("person.hobby=%v\n", person.hobby)
 
}
type Person struct {
 
	name string  //姓名
 
	age int64    //年龄
	
	height int64 //身高
 
	weight int64 //体重
 
	hobby string //爱好
 
}

结构体方法

//type关键字用于定义类型；Student结构体拥有两个属性/字段
type Student struct {
    Name  string
    Score int
}

结构体方法，方法中可以使用结构体变量；
func (s Student) Study() {
    s.Score += 10
}

使用结构体创造类

package main
import "fmt"
// 创建一个学生类
type Student struct {
	id uint
	name string
	age int
	socre uint
}
//学生类的构造函数
func NewStudent(sid uint,s_name string,s_age int,s_score uint) *Student {
	return &Student{id:sid,name:s_name,age:s_age,socre:s_score}
}
//学生类的成员函数Set需要传入指针
func (s *Student) SetStudentName(name string){
	s.name = name
}
//Get不需要传入指针
func (s Student) GetStudentName() string{
	return s.name
}
func main() {
	var stu * Student
	stu = NewStudent(1,"张三",18,18)
	fmt.Printf("stu:%v\n", *stu)
	stu.SetStudentName("李四")
	fmt.Printf("stu:%v age:%v\n", *stu,stu.GetStudentName())
 
}
