详解go 动态数组 二维动态数组

var dynaArr []string

dynaArr = append(dynaArr, "one")
```go

# 结构体数组
```go
package main

import (
 "fmt"
)

type A struct{
 Path string
 Length int 
}

func main() {

 var dynaArr []A

 t := A{"/tmp", 1023}

 dynaArr = append(dynaArr, t)
 dynaArr = append(dynaArr, A{"~", 2048})
 t.Path, t.Length = "/", 4096
 dynaArr = append(dynaArr, t)

 fmt.Println(dynaArr)
 fmt.Println(dynaArr[0])
 fmt.Println(dynaArr[1].Length)
}

➜ testgo go run main.go
[{/tmp 1023} {~ 2048} {/ 4096}]
{/tmp 1023}
2048

func main() {
	var array1 [][]string
	var tmp []string

	tmp = append(tmp, "001")
	tmp = append(tmp, "002")

	array1 = append(array1, tmp)

	fmt.Println(array1)
	fmt.Println(array1[0])
	fmt.Println(array1[0][1])
}

➜ testgo go run main.go 
[[001 002]]
[001 002]
