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: main.go
    path of file: ./repos/learning/golang/source_code/Go语言核心编程代码/chapter14/filedemo05/exe05
    
    the code of the file until where you have to start completion: package main
import (
	"fmt"
	"io/ioutil" 
)
func main() {
	//将d:/abc.txt 文件内容导入到  e:/kkk.txt
	//1. 首先将  d:/abc.txt 内容读取到内存
	//2. 将读取到的内容写入 e:/kkk.txt
	file1Path 
    
func main() {
	//将d:/abc.txt 文件内容导入到  e:/kkk.txt
	//1. 首先将  d:/abc.txt 内容读取到内存
	//2. 将读取到的内容写入 e:/kkk.txt
	file1Path := "d:/abc.txt" 
	file2Path := "e:/kkk.txt" 
	data, err := ioutil.ReadFile(file1Path)
	if err != nil {
		//说明读取文件有错误
		fmt.Printf("read file err=%v\n", err)
		return
	}
	err = ioutil.WriteFile(file2Path, data, 0666)
	if err != nil {
		fmt.Printf("write file error=%v\n", err)
	}
}
