go二維數組追加

                                                                            go二維數組追加

1、打印

 2、代碼

package main

import (
	"fmt"
	"strconv"
)

func main()  {
	names := getNames()
	fmt.Println("打印結果：", names)

	fmt.Println("開始循環一下：")
	for _, value := range names{
		fmt.Println(value[0], "-", value[1])
		//fmt.Println(value[0] + "-" + value[1])
	}
}

//返回一個二維數組
func getNames() [5][2]string{
	//定義一個二維數組
	//result := [5][2]string{}
	//或者
	var result [5][2]string

	//模擬生成5條數據
	for i := 0; i < 5; i++ {
		sign := strconv.Itoa(i)	//int轉字符串
		//sign := strconv.FormatInt(int64,i)	//int64轉字符串
		//int,err:=strconv.Atoi(string)			//string到int
		//int64, err := strconv.ParseInt(string, 10, 64)	//string到int64

		name := "姓名" + sign
		like := "go" + sign

                //數據追加
		result[i][0] = name
		result[i][1] = like
	}
	return result
}
