Generally speaking, you can use the functionality of the io.Writer interface for writing data to files on a disk. Nevertheless, the Go code of save.go will show you five ways to write data to a file. The save.go program will be presented in six parts.
The first part of save.go is as follows:
package main
import (
"bufio"
"fmt"
"io"
"io/ioutil"
"os"
)
The second code portion of save.go is shown in the following Go code:
func main() {
s := []byte("Data to write\n")
f1, err := os.Create("f1.txt")
if err != nil {
fmt.Println("Cannot create file", err)
return
}
defer f1.Close()
fmt.Fprintf(f1, string(s))
Notice that the s byte slice will be used in every line that involves writing presented in this Go program...
