numberofstudents++;}
else if (score < 60){
grade ='F';
numberofstudents++;}
}
System.out.println("Number of A's = " + (numberofstudents++));
System.out.println("Number of B's = " + (numberofstudents++));
System.out.println("Number of C's = "+ (numberofstudents++));
System.out.println("Number of D's = "+ (numberofstudents++));
System.out.println("Number of F's = "+ (numberofstudents++));
System.out.println("Want to score another exam?");
