Given main(), complete the SongNode class to include the function PrintSongInfo(). Then write the PrintPlaylist() function in

Fantastic news! We've Found the answer you've been seeking!

Question:

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

First file : main.cpp

#include "SongNode.h"

// TODO: Write PrintPlaylist() function

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);
}

Second file: SongNode.h

#include "iostream"
#include

using namespace std;

class SongNode {
private:
string songTitle;
string songLength;
string songArtist;
SongNode* nextNodeRef; // Reference to the next node

public:
SongNode() {
songTitle = "";
songLength = "";
songArtist = "";
nextNodeRef = NULL;
}

// Constructor
SongNode(string songTitleInit, string songLengthInit, string songArtistInit);

// Constructor
SongNode(string songTitleInit, string songLengthInit, string songArtistInit, SongNode* nextLoc);

// insertAfter
void InsertAfter(SongNode* nodeLoc);

// Get location pointed by nextNodeRef
SongNode* GetNext();

// Prints song information
void PrintSongInfo();

};

Third file: SongNode.cpp

#include "SongNode.h"

// Constructor
SongNode::SongNode(string songTitleInit, string songLengthInit, string songArtistInit) {
this->songTitle = songTitleInit;
this->songLength = songLengthInit;
this->songArtist = songArtistInit;
this->nextNodeRef = NULL;
}

// Constructor
SongNode::SongNode(string songTitleInit, string songLengthInit, string songArtistInit, SongNode* nextLoc) {
this->songTitle = songTitleInit;
this->songLength = songLengthInit;
this->songArtist = songArtistInit;
this->nextNodeRef = nextLoc;
}

// insertAfter
void SongNode::InsertAfter(SongNode* nodeLoc) {
SongNode* tmpNext;
tmpNext = this->nextNodeRef;
this->nextNodeRef = nodeLoc;
nodeLoc->nextNodeRef = tmpNext;
}

// Get location pointed by nextNodeRef
SongNode* SongNode::GetNext() {
return this->nextNodeRef;
}

// TODO: Write PrintSongInfo() function
