Modularity: The main function should create the Playlist object and call at least three other functions:
- Get the data from the user. Using a loop, have the user populate the playlist object array with 10 artist and songs in no particular order. No validation is necessary. However, you should use the C++ getline function instead of cin so that the user can type spaces in the name and song title.
- Sort the list. You may use either the bubble sort or the selection sort to sort your playlist.
- Display the list. The function should display the artist and title in sorted order with appropriate headings.
- Rewrite this program using a class object separately.

The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores: Test Score Letter Grade 90–100 A 80-89 B 70-79 C 60-69 D 0-59 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade.
