You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 19_数组.go
    path of file: ./repos/learning/golang/source_code/Go语言基础与提升课程资料/源码
    
    the code of the file until where you have to start completion: package main

import "fmt"

	//数组的定义
	var arr0 [10]int
	arr0[0] = 1
	arr0[1] = 2
	fmt.Println("arr0的值是：", arr0)
	for i := 0; i < 10; i++ {
		arr0[i] = i + 1

	fmt.Println("通过for循环赋值之后的arr0的值是：", arr0)
	//数组的4种初始化方法

	fmt.Println("初始化方法1：", arr1)
