How to skip a certain number of bytes in a bufio.Reader in Go?

To skip a certain number of bytes in a bufio.Reader in Go, you can use the Reader.Discard() method. Discard() reads and discards the specified number of bytes from the underlying io.Reader, advancing the reader's position.

Here's an example of how you can use Discard() to skip a specific number of bytes in a bufio.Reader:

package main

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

func main() {
	// Open the file for reading
	file, err := os.Open("example.txt")
	if err != nil {
		fmt.Println("Failed to open file:", err)
		return
	}
	defer file.Close()

	// Create a bufio.Reader to read from the file
	reader := bufio.NewReader(file)

	// Skip the first 10 bytes
	_, err = reader.Discard(10)
	if err != nil {
		fmt.Println("Failed to discard bytes:", err)
		return
	}

	// Read and print the remaining content
	remainingContent, err := reader.ReadString('\n')
	if err != nil {
		fmt.Println("Failed to read remaining content:", err)
		return
	}
	fmt.Println(remainingContent)
}

In this example, the Discard() method is used to skip the first 10 bytes in the file "example.txt". After skipping the specified number of bytes, the remaining content is read and printed to the console.

Make sure to handle any errors that may occur during this process.
