Develop a program that calculates Grade Point Average (GPA) for students. A grade of A is worth 4 points, B is worth 3 points, C is worth 2 points, D is worth 1 points and F is worth 0 points. Grades other than A, B, C, D, and F should not be calculated in GPA. When a grade is entered for a course, credit hours for that course should also be entered so that the GPA can be calculated correctly. For example, if a student has taken 3 courses and earned the following grades: Course Grade Credit Hours 1 A 3.0 2 B 4.5 3 A 1.0 The students GPA should be calculated as GPA = (4.0*3.0 + 3.0 * 4.5 + 4.0*1.0) / (3.0+4.5+1.0) A student can take up to 5 courses. Only A, B, C, D, F, W, P are allowed for grade
