C + + You will be building a linked list. Make sure to keep track of both the head and tail nodes. Step 1 :

C++
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
Parameterized constructor
Public member functions
GetID()- Accessor
GetSongName()- Accessor
GetArtistName()- Accessor
GetSongLength()- Accessor
GetNext()- Accessor
InsertAfter(PlaylistNode* nodePtr)- Mutator
SetNext(PlaylistNode* nodePtr)- Mutator
PrintPlaylistNode()- Outputs uniqueID, songname, artistName, and songLength based on the format example below.
Ex. of PrintPlaylistNode output:
Unique ID: S123
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.
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 'q'. 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().
If the list is empty, output: Playlist is empty
Ex:
JAMZ - OUTPUT FULL PLAYLIST
1.
Unique ID: SD123
Song Name: Peg
Artist Name: Steely Dan
Song Length (in seconds): 237
2.
Unique ID: JJ234
Song Name: All For You
Artist Name: Janet Jackson
Song Length (in seconds): 391
3.
Unique ID: J345
Song Name: Canned Heat
Artist Name: Jamiroquai
Song Length (in seconds): 330
4.
Unique ID: JJ456
Song Name: Black Eagle
Artist Name: Janet Jackson
Song Length (in seconds): 197
5.
Unique ID: SD567
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()
New additions are added to the end of the list.
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
Step 8: Implement the "Remove song" menu option in ExecuteMenu()
Prompt the user for the unique ID of the song to be removed.
Ex:
REMOVE SONG
Enter song's unique ID:
JJ234
"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
Moving the tail node
Moving a node to the head
Moving a node to the tail
Moving a node up the list
Moving a node down the list
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().
Prompt the user for the artist's name, and output the node's information, starting with the node's current position.
Step 11: Implement the "Output total time of playlist" menu option in ExecuteMenu().
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
