golang中的二维数组和二维切片

golang中数组和切片用的比较多，下面给个demo看看二维的数组和二维切片。

package main

import (
 "fmt"
)

func printarray(a [2][2]string) {
 for _, v1 := range a {
  for _, v2 := range v1 {
   fmt.Printf("%s ", v2)
  }
  fmt.Printf("\n")
 }
}

func main() {
 //数组长度固定，数组是值类型
 a := [2][2]string{
  {"00", "01"},
  {"10", "11"},
 }
 printarray(a)
 var b [2][2]string
 b[0][0] = "00"
 b[0][1] = "01"
 b[1][0] = "10"
 b[1][1] = "11"
 fmt.Printf("\n")
 printarray(b)

 //不固定大小
 pls := [][]string {
  {"00", "01"},
  {"10","11","12"},
 }
 for _, v1 := range pls {
  for _, v2 := range v1 {
   fmt.Printf("%s ", v2)
  }
  fmt.Printf("\n")
 }

 fmt.Println(cap(pls))
}
