(1) Create three files.
Playlist.h - Class declaration, Playlist.cpp - Class definition, main.cpp - main() function to run
(2) Build the PlaylistNode class.
Default constructor Parameterized constructor
Public member functions: InsertAfter(), SetNext() - Mutator, 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.
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.
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
Ex:
JAMZ - OUTPUT FULL PLAYLIST
Unique ID: SD123 Song Name: Peg Artist Name: Steely Dan Song Length (in seconds): 237
Unique ID: JJ234 Song Name: All For You Artist Name: Janet Jackson Song Length (in seconds): 391
Unique ID: J345 Song Name: Canned Heat Artist Name: Jamiroquai Song Length (in seconds): 330
(5) Implement the "Add song" menu item. 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
(6) Implement the "Remove song" function. 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
(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 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
(8) Implement the "Output songs by specific artist" menu option.
Ex: OUTPUT SONGS BY SPECIFIC ARTIST Enter artist's name: Janet Jackson
Unique ID: JJ234 Song Name: All For You Artist Name: Janet Jackson Song Length (in seconds): 391
Unique ID: JJ456 Song Name: Black Eagle Artist Name: Janet Jackson Song Length (in seconds): 197
(9) Implement the "Output total time of playlist" menu option. 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
Example Screenshot of program:
- Menu
- Option a (add a song)
- Option o (output full playlist)
- Option c (change the postion)
- Option t (output legnth of playlist in seconds)
- Option d (delete a song)
