You will be building a linked list. Make sure to keep track of both the head and tail nodes.

(1) Create three files to submit.

PlaylistNode.h - Class declaration
PlaylistNode.cpp - Class definition
main.cpp - main() function

Build the PlaylistNode class per the following specifications. Note: Some functions can initially be function stubs (empty functions), to be completed in later steps.

Default constructor (1 pt)
Parameterized constructor (1 pt)
Public member functions
- InsertAfter() - Mutator (1 pt)
- SetNext() - Mutator (1 pt)
- GetID() - Accessor
- GetSongName() - Accessor
- GetArtistName() - Accessor
- GetSongLength() - Accessor
- GetNext() - Accessor
- PrintPlaylistNode()
Private data members
- string uniqueID - Initialized to "none" in default constructor
- string songName - Initialized to "none" in default constructor
- string artistName - Initialized to "none" in default constructor
- int songLength - Initialized to 0 in default constructor
- PlaylistNode* nextNodePtr - Initialized to 0 in default constructor

Ex. of PrintPlaylistNode output:

Unique ID: S123

Song Name: Peg

Artist Name: Steely Dan

Song Length (in seconds): 237

(2) In main(), prompt the user for the title of the playlist. (1 pt)

Ex:

Enter playlist's title:

JAMZ

(3) Implement the PrintMenu() function. PrintMenu() takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist. Each option is represented by a single character. Build and output the menu within the function.

If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to execute the menu until the user enters q to Quit. (3 pts)

Ex:

JAMZ PLAYLIST MENU

a - Add song

d - Remove song

c - Change position of song

s - Output songs by specific artist

t - Output total time of playlist (in seconds)

o - Output full playlist

q - Quit

Choose an option:

(4) Implement "Output full playlist" menu option. If the list is empty, output: Playlist is empty (3 pts)

Ex:

JAMZ - OUTPUT FULL PLAYLIST

Unique ID: SD123

Song Name: Peg

Artist Name: Steely Dan

Song Name: Black Eagle

Artist Name: Janet Jackson

Song Length (in seconds): 197

Unique ID: SD567

Song Name: I Got The News

Artist Name: Steely Dan

(5) Implement the "Add song" menu item. New additions are added to the end of the list. (2 pts)

Ex:

ADD SONG

Enter song's unique ID: SD123

Enter song's name: Peg

Enter artist's name: Steely Dan

Enter song's length (in seconds): 237

(6) Implement the "Remove song" function. Prompt the user for the unique ID of the song to be removed.(4 pts)

Ex:

REMOVE SONG

Enter song's unique ID:

JJ234

"All For You" removed

(7) Implement the "Change position of song" menu option. Prompt the user for the current position of the song and the desired new position. Valid new positions are 1 - n (the number of nodes). If the user enters a new position that is less than 1, move the node to the position 1 (the head). If the user enters a new position greater than n, move the node to position n (the tail). 6 cases will be tested:

Moving the head node (1 pt)
Moving the tail node (1 pt)
Moving a node to the head (1 pt)
Moving a node to the tail (1 pt)
Moving a node up the list (1 pt)
Moving a node down the list (1 pt)

Ex:

CHANGE POSITION OF SONG

Enter song's current position:

Enter new position for song:

"Canned Heat" moved to position 2

(8) Implement the "Output songs by specific artist" menu option. Prompt the user for the artist's name, and output the node's information, starting with the node's current position. (2 pt)
