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 students set of test scores and average score. The program should allow the user to enter each students name and his or her four test scores . It should then calculate and display each students 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)
