8.17 LAB: Playlist (output linked list) Given main(), complete the SongNode class to include the function PrintSonginfo(). Then write the PrintPlaylist() function in main.cpp to print all songs in the playlist. DO NOT print the dummy head node. Ex: If the input is: Stomp ! 380 The Brothers Johnson The Dude 337 Quincy Jones You Don't Own Me 151 Lesley Gore -1 the output is: LIST OF SONGS Title: Stomp! Length: 380 Artist: The Brothers Johnson Title: The Dude Length: 337 Artist: Quincy Jones Title: You Don't Own Me Length: 151 Artist: Lesley Gore 464730.3214874.4x32gy7 LAB 8.17.1: LAB: Playlist (output linked list) 0 / 10 ACTIVITY Scanned with CamScanner Current file and dofault templateLAB ACTIVITY 8.17.1: LAB: Playlist (output linked list) 0 / 10 Current file: main.cpp Load default template... 1 #include #include "SongNode. h" // TODO: Write PrintPlaylist( ) function int main ( ) { SongNode* headNode; SongNode* currNode ; SongNode* lastNode; 10 11 string songTitle; 12 string songLength; 13 string songArtist; 14 15 // Front of nodes list 16 headNode = new SongNode ( ) ; 17 lastNode = headNode; 18 Run your program as often as you'd like, before submitting for grading.
