Write a program to determine the equivalent grade of each student in a class as follows: a. Read in the student's name, midterm grade, minor B, and final exam ratings. b. Determine the final grade of the student by formula: final grade = 0.30 of midterm grade + 0.10 of minor B + 0.60 of final exam. c. Determine the equivalent grade for the numerical value obtained by the following grading marks: 98 - 100 = 4.00 95 - 97 = 3.75 92 - 94 = 3.50 89 - 91 = 3.25 86 - 88 = 3.00 83 - 85 = 2.75 80 - 82 = 2.50 77 - 79 = 2.25 74 - 76 = 2.00 71 - 73 = 1.75 68 - 70 = 1.50 64 - 67 = 1.25 60 - 63 = 1.00 below 60= 0.00
