Submitted by Nidhi, on April 07, 2021

Problem Solution:

In this program, we will read data from the file in a single line using the ReadFile() function of the "ioutil" package.

Program/Source Code:

The source code to read data from the 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 read data from the file
// in a single line

package main

import "io/ioutil"
import "fmt"

func main() {
	fileData, _ := ioutil.ReadFile("Sample.txt")
	fmt.Printf("Data in file: %s\n", fileData)
}

Output:

Data in file: Hello World

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 read data from file in a single line using ReadFile() function of "ioutil" package.

After that, we printed the result on the console screen.
