LAB$*$: Program: Playlist

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

Step $1$: Create three files to submit and build the PlaylistNode class.

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.

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

Default constructor $(1$ pt$)$

Parameterized constructor $(1$ pt$)$

Public member functions

GetID$()-$ Accessor

GetSongName$()-$ Accessor

GetArtistName$()-$ Accessor

GetSongLength$()-$ Accessor

GetNext$()-$ Accessor

InsertAfter$($PlaylistNode$*$ nodePtr$)-$ Mutator $(1$ pt$)$

SetNext$($PlaylistNode$*$ nodePtr$)-$ Mutator $(1$ pt$)$

PrintPlaylistNode$()-$ Outputs uniqueID, songname, artistName, and songLength based on the format example below.

Ex$.$ of PrintPlaylistNode output:

Unique ID: S$123$

Song Name: Peg

Artist Name: Steely Dan

Song Length $($in seconds$)$: $237$

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

Ex:

Enter playlist's title:

JAMZ

Step $3$: Implement the PrintMenu$()$ function. $(1$ pt$)$

PrintMenu$()$ takes the playlist title as a parameter and outputs a menu of options to manipulate the playlist.

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

Step $4$: Implement the ExecuteMenu$()$ function. $(1$ pt$)$

ExecuteMenu$()$ takes $3$ parameters: a character representing the user's choice, a playlist title, and the pointer to the head node of a playlist. ExecuteMenu$()$ performs the menu options $($described below$)$ according to the user's choice and returns the pointer to the head node of the playlist.

Step $5$: In main$(),$ call PrintMenu$()$ and prompt for the user's choice of menu options. $(1$ pt$)$

Each option is represented by a single character. If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute the option by calling ExecuteMenu$().$ Then, print the menu, and prompt for a new option. Continue until the user enters $\text{'}$q$\text{'}.$ Hint: Implement Quit before implementing other options.

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:

Step $6$: Implement "Output full playlist" menu option in ExecuteMenu$().(3$ pts$)$

If the list is empty, output: Playlist is empty

Ex:

JAMZ $-$ OUTPUT FULL PLAYLIST

$1.$

Unique ID: SD$123$

Song Name: Peg

Artist Name: Steely Dan

Song Length $($in seconds$)$: $237$

$2.$

Unique ID: JJ$234$

Song Name: All For You

Artist Name: Janet Jackson

Song Length $($in seconds$)$: $391$

$3.$

Unique ID: J$345$

Song Name: Canned Heat

Artist Name: Jamiroquai

Song Length $($in seconds$)$: $330$

$4.$

Unique ID: JJ$456$

Song Name: Black Eagle

Artist Name: Janet Jackson

Song Length $($in seconds$)$: $197$

$5.$

Unique ID: SD$567$

Song Name: I Got The News

Artist Name: Steely Dan

Song Length $($in seconds$)$: $306$

Step $7$: Implement the "Add song" menu option in ExecuteMenu$().(2$ pts$)$

New additions are added to the end of the list.

Ex:

ADD SONG

Enter song's unique ID:

SD$123$

Enter song's name:

Peg

Enter artist's name:

Steely Dan

Enter song's length $($in seconds$)$:

$237$

Step $8$: Implement the "Remove song" menu option in ExecuteMenu$().(4$ pts$)$

Prompt the user for the unique ID of the song to be removed.

Ex:

REMOVE SONG

Enter song's unique ID:

JJ$234$

"All For You" removed.

Step $9$: Implement the "Change position of song" menu option in ExecuteMenu$().$

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 $1($immediately after 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:

$3$

Enter new position for song:

$2$

"Canned Heat" moved to position $2$

Step $10$: Implement the "Output songs by specific artist" menu option in ExecuteMenu$().(2$ pt$)$

Prompt the user for the artist's name, and output the node's information, starting with the node's current position.

EX:

OUTPUT SONGS BY SPECIFIC ARTIST

Enter artist's name:

Janet Jackson

$2.$

Unique ID: JJ$234$

Song Name: All For You

Artist Name: Janet Jackson

Song Length $($in seconds$)$ : $391$

$4.$

Unique ID: JJ$456$

Song Name: Black Eagle

Artist Name: Janet Jackson

Song Length $($in seconds$)$ : $197$

Step $11$: Implement the "Output total time of playlist" menu option in ExecuteMenu$().(2$ pts$)$

output the sum of the time of the playlist's songs $($in seconds$).$

Ex:

OUTPUT TOTAL TIME OF PLAYLIST $($IN SECONDS$)$

Total Time: $1461$ seconds
