Exercise set #9

(I think I've slipped up in counting these exercise numbers - I'll
check)

Due:  Monday, April 19

The file class.dat contains records organized as follows:

	Record #1 is a number giving the number of student records
		which follow.

	The remaining records follow the pattern of student.dat

Write a program called class.cpp which will do the following steps:

Create a record as in student.cpp (be sure to include the student's 
	class average and letter grade in the record).

Create an array of these records.  Your array should accomodate at
	least 30 students (though the number may vary from run to run).

The program should then

1.	Read in records into the array from the file class.dat.  Read in
		the records only - do not calculate anything in this step.

2.	Go through the array, calculating, for each student, the student's
		class average and letter grade.

3.	Sort the array in ascending order by student name (remember
		to use strcmp).  Use any sorting algorithm you want to use, but
		be sure to name it.

4.	Print a report of the class with a title, a column header line, and student
		records (including name, quiz scores, exam scores, class average, and
		letter grade).  Include a footer which summarizes
			the number of students in the class
			the average on each quiz and exam
			the average student average
			the class GPA (counting an A as 4, a B as 3, and so on).
