 In this exercise you will write a program to obtain a student's grade point average (GPA). Suppose that all courses in Yauco's University are $$3$$ credits each and have the following point values: $$A = 4$$ points per credit; $$B = 3$$ points per credit; $$C = 2$$ points per credit; $$D = 1$$ point per credit and $$F = 0$$ points per credit.
