Submitted by Nidhi, on April 07, 2021

Problem Solution:

In this program, we will write data into a file in a single line using the WriteFile() function of the "ioutil" package.

Program/Source Code:

The source code to write data into a file in a single line is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to write data into a
// file in a single line

package main

import "io/ioutil"
import "fmt"

func main() {
	ioutil.WriteFile("NewFile.txt", []byte("Hello India\n"), 0666)
	fmt.Println("Data written in file successfully")
}

Output:

Data written in file successfully

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the "fmt", "io/ioutil" packages then we can use a function related to the "fmt" and "ioutil" package.

In the main() function, we wrote data into file in a single line using WriteFile() function of "ioutil" package.

After that, we printed the "Data written in file successfully" message on the console screen.
