Submitted by Nidhi, on April 05, 2021

Problem Solution:

In this program, we will create a text file and save text data into the specified text file.

Program/Source Code:

The source code to create a text file is given below. The given program is compiled and executed successfully.

// Golang program to Create a text file

package main

import "fmt"
import "os"

func main() {
	file, err := os.Create("Sample.txt")
	if err != nil {
		fmt.Println("Unable to open file: %s", err)
	}

	len, err := file.WriteString("Hello World")

	if err != nil {
		fmt.Println("Unable to write data: %s", err)
	}
	file.Close()

	fmt.Printf("%d character written successfully into file", len)
}

Output:

11 character written successfully into file

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, os packages then we can use a function related to the fmt and os package.

In the main() function, we created a file "Sample.txt" using os.Create() function and write text data into file using WriteString() file. The WriteString() function returns the number of characters written into the file.
