How to write a string to a bufio.Writer in Go?

To write a string to a bufio.Writer in Go, you can use the WriteString() method. Here's an example:

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {
	// Create a new bufio.Writer
	writer := bufio.NewWriter(os.Stdout)

	// Write a string to the writer
	str := "Hello, World!"
	_, err := writer.WriteString(str)
	if err != nil {
		fmt.Println("Error writing string:", err)
		return
	}

	// Flush the writer to ensure the string is written to the underlying io.Writer
	err = writer.Flush()
	if err != nil {
		fmt.Println("Error flushing writer:", err)
		return
	}
}

In this example, we create a new bufio.Writer that writes to the standard output (os.Stdout). We then use the WriteString() method to write the string Hello, World! to the writer. The Flush() function is then called to ensure that the string is written to the underlying os.Stdout.
