Can someone answer these questions about the code? (only in words no code required unless you need to copy mine and put a section to answer a question.)

********DON'T GET THROWN OFF BY HOW MUCH STUFF THERE IS I ONLY NEED ANSWERS TO THE QUESTIONS IN BOLD.*******

1)What functions does the ADT have

2)How each function will report success/failure back to the calling routine

3)How each function will shield the client program from the details of the data structure

4)What data structures you will be using and how each of the special cases.

5)Which function/functions are recursive?

6) What are the design considerations, what are the main design considerations, why they are the main design considerations, and how this program solved the problems?

**********************I have already written my code and this is what it is supposed to do.************************

"Part I: The Song ADT

The information about a song should include:

Artist name (e.g., Eminem)

Title(e.g., Lose Yourself)

Length (e.g., 5.23)

Number of likes (e.g., 654,000)

Part II: The SongList ADT

The data members for SongList should be a head pointer to a linear linked list of Song objects and the number of songs in the list. The songs should be organized by popularities with the most popular song as the first node in the list.

This ADT must have public member functions to perform the following:

1.Constructor - Construct an object and initialize the data members

2.Destructor - Release all dynamic memory and reset data members to their zero equivalent value

3.Add a new song

4.Edit the number of likes for a song

5.Display all songs in the list

6.Display all songs for an artist (in order of popularity)

7.Remove all songs with fewer than M likes, where M is sent in as an argument

Part III: The driver or the test program

The test program needs to first load the test data set from external file at the beginning of the program.

The menu-based user interface should allow user to use/test ALL the functionalities of the program. Try to make the user interface easier to use."
