Modify the program

Modify the Test Scores program from the above Debug Section into a class grade book that includes a class of up to 20 students and 3 test grades. Each test is read in as a separate file, so 3 Test files are required. The students' grades should be kept in an array. Once all three test scores are read in, calculate each student's average and grade for the class. Also print a report of the each student's test grades, average and final grade as a table, and then print the averages of each Test and overall Test Average, as well as highest Test Grade of all Tests and the student with thehighest class grade.

Required for program grade:

1. Source Code (complete)
2. Sample Input files
3. Screenshot of running program.
