Golang : Write file with io.WriteString

Writing to a file in Golang is easy. There are couple of ways to do it. In this tutorial, we will show you how to write into plain text file.

 package main

 import (
 "os"
 "io"
 "fmt"
 )

 func main() {

 filename := "output.txt"

 file, err := os.Create(filename)

 if err != nil {
 fmt.Println(err)
 }

 fmt.Println(" Write to file : " + filename)

 n, err := io.WriteString(file, " Hello World !")

 if err != nil {
 fmt.Println(n, err)
 }

 file.Close()
 }
