Develop an interactive program to assist a Philosophy professor in reporting students’ grades for his PHIL-224.N1 to the Office of Registrar at the end of the semester. Display an introductory paragraph for the user then prompt the user to enter a student record (student ID number and five exam-scores – all on one line). The scores will be in the range of 0-100. The sentinel value of -1 will be used to mark the end of data. The instructor has...

C++: Create a grade book program that includes a class of up to 20 students each with 5 test grades (4 tests plus a Final). The sample gradebook input file (CSCI1306.txt) is attached. The students’ grades should be kept in an array. Once all students and their test scores are read in, calculate each student’s average (4 tests plus Final counts double) and letter grade for the class. The output of this program is a tabular grade report that is...
