Question

Create a song class. Each song will have:

In addition the class should have the following functions:

void setArtistName(string name); // Sets name to the artist name in the object

void setMinutes(int min); // Sets the minutes in the object

void setSeconds(int secs); // Sets seconds for the song (minutes + seconds equals total length)

void setComposer(string comp);

void setSongTItle(string songName); // sets song title in the object

void setAlbumName(string albumName); // sets the title of the album.

void displaySong(); // displays the song's information

string getArtistName(); // Returns the artist information

int getMinutes(); // Returns the minutes in the object

int getSeconds(); // Returns the seconds for the song (minutes + seconds equals total length)

string getComposer(); // Returns the composer

string getSongTItle(); // Returns song title in the object

string getAlbumName(); // Returns the title of the album.

Your main function should then make 3 song objects and display their information from shortest song to longest song. Upload a zipped file with the .h, and 2 .cpp files (one for the implementation and one for the main()).
