Input marks of five subjects and calculate the grade
Physics, Chemistry, Biology, Mathematics and Computer. Calculate percentage and grade according to following:
Percentage >= 80% : Grade A+
Percentage >= 75% : Grade A
Percentage >= 70% : Grade A-
Percentage >= 65% : Grade B+
Percentage >= 60% : Grade B
Percentage >= 55% : Grade B-
Percentage >= 50% : Grade C+
Percentage >= 45% : Grade C
Percentage >= 40% : Grade D
Percentage < 40% : Grade F
Sample Output
Physics: 83 Chemistry: 89 Biology: 71 Mathematics: 85 Computer: 82 Grade A+ Process returned 0 (0x0) execution time : 15.385 s Press any key to continue.
