A teacher has five students who have taken four tests. 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. Write a C++ program that uses an array of string objects to hold the five student names , an array of one character to hold the five students� letter grades , and five arrays of doubles to hold each student�s set of test scores and average score. The program should allow the user to enter each student�s name and his or her four test scores . It should then calculate and display each student�s average test score and a letter grade based on the average . Input Validation: Do not accept test scores less than 0 or greater than 100 . Score Letter Grade 90� 100 A 80-89 B 70-79 C 60-69 D 0-59 F. (Please show output)
