You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: read_buffered.go
    path of file: ./repos/Cookbook/go/files
    
    the code of the file until where you have to start completion: package main

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

func main() {
	// Open file and create a buffered reader on 
    
func main() {
	// Open file and create a buffered reader on top
	file, err := os.Open("test.txt")
	if err != nil {
		log.Fatal(err)
	}
	bufferedReader := bufio.NewReader(file)

	// Get bytes without advancing pointer
	byteSlice := make([]byte, 5)
	byteSlice, err = bufferedReader.Peek(5)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Peeked at 5 bytes: %s\n", byteSlice)

	// Read and advance pointer
	numBytesRead, err := bufferedReader.Read(byteSlice)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Read %d bytes: %s\n", numBytesRead, byteSlice)

	// Ready 1 byte. Error if no byte to read
	myByte, err := bufferedReader.ReadByte()
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Read 1 byte: %c\n", myByte)		

	// Read up to and including delimiter
	// Returns byte slice
	dataBytes, err := bufferedReader.ReadBytes('\n') 
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Read bytes: %s\n", dataBytes)			

	// Read up to and including delimiter
	// Returns string	
	dataString, err := bufferedReader.ReadString('\n')
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Read string: %s\n", dataString)		

	// This example reads a few lines so test.txt
	// should have a few lines of text to work correct
}
