Go初始化结构体数组/切片

package main

import "fmt"

func main() {

	var s []student
	fmt.Printf("%T
", s) //[]main.student
	fmt.Println(s) //[]
	//初始化结构体切片
	s = []student{
		{
			name: "yang",
			age:  18,
		},
	}
	fmt.Println(s) //[{yang 18}]

	var s2 [5]student
	fmt.Printf("%T
", s) //[]main.student
	fmt.Println(s2) //[{ 0} { 0} { 0} { 0} { 0}] //默认值空和零
	//初始化结构体数组
	s2 = [5]student{
		{
			name: "yang",
			age:  18,
		},
	}
	fmt.Println(s2) //[{yang 18} { 0} { 0} { 0} { 0}]
