A student wants to know his grade point average for the semester. The grades are given in letter grades with numeric equivalents. Develop a solution to calculate a grade point average given the letter grades. (Remember, the grade point average is figured per unit of credit, not per course.) An A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Test the solution with the following data:

(Hint: Use a trip value to stop the processing of the loop and a case structure to find the grade points.)
