A group of five students earned the following grades: Student 1, ‘A’; student 2, ‘C’; student 3,‘B’; student 4, ‘A’and student 5, ‘B’. Write an application that reads a series of pairs of numbers as follows:

a) Student name 

b) Student letter grade.

Your program should use a switch statement to determine how many students got a grade of ‘A’, how many got a grade of ‘B’, how many got a grade of ‘C’, and how many got a grade of ‘D’. Use a loop as needed to input the five student grades, and then finally display the results.
