grades.c grades.c will contain 2 functions, grade and gradePrint. grade will do the following: • Receive 9 positive integers. The first 4 integers will be the student average for attendance, assignments, programs and quizzes. The 5 integer will be the final exam grade. The last 4 integers will represent the percentage values for the attendance, assignments, programs, and quizzes. • Return an integer that will be the final grade for the course. . If any grade received is less than 0 or more than 105, the function will return -1. If any percentage received is less than 0 or more than 100, the function will return . • • The sum of all the percentages can not exceed 100. If they do, the function will return-3. • The percentage for the final will be computed as the difference between the sum of the percentages received and 100. gradePrint will do the following: • Receive an integer that represents the numeric grade for the course. . If the integer received is not in the range of 0-105, then the error message"## is not a valid grade", where ## is the value received. It will then exit with a value of 1 • Convert the course numeric grade into a letter grade. See the class syllabus final grade assignments to do the conversion. Note: A+ goes to a grade of 105 Display the course grade and a message using the following and return a value of 0: • • grade A+, A, or A- Message: Excellent grade B+, B, or B- Message: Good grade C+, C, or C- Message: Fair grade D+, D, or D- Message: Poor grade F Message: Failing Grade
[This is not a graded assignment! ]
Please help me modify this code. It is complete and it runs perfectly :], but does not follow the assignment.
