golang 基本数据结构使用

１　goalng struct

1.1 var s1 student

1.2 s2 := student {"zhou", 33}

1.3 s3 := student {Name:"zhou", Age:33}

1.4 s4 := new(student)   // 包含空值的指针

1.5 s5 := make([]strudent, 2) // student slice

package main

import (
	"fmt"
)

type student struct {
	Name string
	Age  int
}

func main() {
	//1.1
	var s student
	s.Name = "zhang"
	s.Age = 18
	fmt.Println(s)
	//1.2
	s2 := student{"zhou", 30}
	fmt.Println(s2)
	//1.3
	s3 := student{
		Name: "zha",
		Age:  33,
	}
	fmt.Println(s3)
	//1.4
	s4 := new(student)
	s4.Name = "www"
	s4.Age = 18
	fmt.Println(s4)
	//1.5
	s5 := make([]student, 2)
	fmt.Println(s5)
}
