This task build on 5.1P Track File Handling where you made the program read in a number of tracks from a file.

Tracksearch.rb -

require './input_functions'

# Task 6.1 T - use the code from 5.1 to help with this

class Track

attr_accessor :name, :location

def initialize (name, location)

@name = name

@location = location

end

end

# Reads in and returns a single track from the given file

def read_track(music_file)

# fill in the missing code

end

# Returns an array of tracks read from the given file

def read_tracks(music_file)

count = music_file.gets().to_i()

tracks = Array.new()

# Put a while loop here which increments an index to read the tracks

track = read_track(music_file)

tracks

return tracks

end

# Takes an array of tracks and prints them to the terminal

def print_tracks(tracks)

# print all the tracks use: tracks[x] to access each track.

end

# Takes a single track and prints it to the terminal

def print_track(track)

puts('Track title is: ' + track.title)

puts('Track file location is: ' + track.file_location)

end

# search for track by name.

# Returns the index of the track or -1 if not found

def search_for_track_name(tracks, search_string)

# Put a while loop here that searches through the tracks

# Use the read_string() function from input_functions.

# NB: you might need to use .chomp to compare the strings correctly

# Put your code here.

return found_index

end

# Reads in an Album from a file and then prints all the album

# to the terminal

Please answer this question with the appropriate steps, otherwise you would be subject to reporting

This task build on 5.1P Track File Handling where you made the program read in a number of tracks from a file. In this task you need to do or include the following: Once the track information is loaded, prompt the user to enter a search string (use the read_string() function from the library. The search function should have the following prototype: search_for_track_name(tracks, search_name) - where tracks is an array of tracks and is the string being searched for. The function should return 1 if the track name is not found, otherwise it should return the array index of the track with that name. Display a message indicating if the track has been found or not (this is provided in the sample code in Resources). Make sure you test for a track that does exist and one that does not. An example of the expected output of your program is provided below: Crackling Rose sounds/01-Cracklin-rose.wav Soolaimon sounds/06-Soolaimon. wav Sweet Caroline sounds/20-Sweet_Caroline.wav Enter the track name you wish to find: Soolaimon Found Soolaimon at 1 MacBook-Pro-6:6.2 T Arrav search mmitchell\$
