8.18 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:
the output is:
// main.cpp
#include <iostream>
#include "SongNode.h"
// TODO: Write PrintPlaylist() function
void PrintPlaylist(SongNode *song) {
}
int main() {
SongNode* headNode;
SongNode* currNode;
SongNode* lastNode;
string songTitle;
string songLength;
string songArtist;
// Front of nodes list




headNode = new SongNode();
lastNode = headNode;
// Read user input until -1
entered
getline(cin, songTitle);
while (songTitle != "-1") {
getline(cin,
songLength);
getline(cin, songArtist);
currNode = new
SongNode(songTitle, songLength, songArtist);

lastNode->InsertAfter(currNode);
lastNode = currNode;
getline(cin,
songTitle);
}
// Print linked list
cout << "LIST OF SONGS" <<
endl;
cout << "-------------" <<
endl;
PrintPlaylist(headNode);

return 0;
