The XYZ Secondary School needs a program to analyze the test results of students. Each class consists of 30 students. The program should allow the user to enter the Integer test marks of all the students in a class using an input dialog box (refer to Figure 1a). After entering the marks of 30 students, the program will display each grade and number of students who scored that grade (refer to Figure 1b for sample output). A 30-element array marks of type Integer is created to store the marks of a class entered by the user.
