Question #55470
Write a program to calculate students average test scores and their grades.
Use three arrays: a one-dimensional array to store the student names, a (parallel) two- dimensional array to store the test score, and a parallel one-dimensional array to store grades. Your program must contain at least the following methods: a method to read and to store data into two arrays, a method to calculate the average test score and grade and a method to output the result. Have your program also output the class average.
