数组的使用

package main

import "fmt"

// 数组的定义 var 数组变量名 [元素数量]T
func def_array() {
    var a [3]int
    a[0] = 0
    a[1] = 1
    a[2] = 2
    fmt.Println(a)
}

// 数组是值传递
func modifyarray(a [3]string) {
    a[0] = "加拿大"
}

func initArray() {
    a := [3]int{}
    fmt.Println(a)
    var numArray = [3]int{1, 2, 3}
    fmt.Println(numArray)
}

func main() {
    a := [3]string{"美国", "新加坡", "台湾"}
    fmt.Println(a)
    modifyarray(a)
    fmt.Println(a)

    b := [2][3]string{
        {"a", "b", "c"},
        {"d", "e", "f"},
    }
    fmt.Println(b)
}
