Question

Write a C++ class called Song to represent a song in a music collection. The data members of the Song class are strings representing the song title, artist’s name, and the album where the song can be found. These instance variables for the class are to have private access modifiers so I need to write the appropriate functions to allow a client to access and modify the data values. In addition, I need to write an overloaded equality (==) function; two songs are equal if they have the same title, artist, and album, regardless of the case of the letters. I also need to implement an overloaded greater-than (>) function because I will be using this program throughout the semester.

A second file is to be written called SongList that contains a main function and separate function to display a menu of options for the user. The menu will contain options that allow the user to:

1. Add a song
2. Remove a song
3. Display all the songs in the list
4. Quit


****Just a quick note: Someone asked the same question a little while ago but the answer was wrong. I tested the solution and it did not work.

Explanation / Answer

Only thing I could not figure out was how to successfully delete an entire song object from the vector I created in the driver. This should give you a nice start though. Please Rate! DRIVER PROGRAM
