Project #3: Using struct and hierarchical class data type to write a simple student records report program with sorting function

This project is an elaboration of Project 2. However, it requires using hierachical class types to organize student records.

Use Visual C++ to write your program.

As records secretary for Cougar High School, you have been asked by the principal to prepare a report on the grades of some of the school's top athletes. Specifically, you must print each of the athlete's average letter grades based on their scores from three academic courses. Input will be taken from the file stufile.txt, which is organized as follows: Each athlete in the file has four lines of information recorded - name (at most 20 characters including the comma and white space), student ID (SS#), class rank (1=Freshman, 2=Sophomore, 3=Junior, 4=Senior), and the three scores. Information for at most 15 athletes is stored in the file, but the first line of the file contains an integer showing the exact number of athletes.

Use class as data representation of a student record, which include both data and operations. Then, define another class to hold an array of student records and encapsulate some member functions which will be used to do the specified reporting as described in the following. Look at the sample specification file proj3_prototype.h for the suggested data type declarations. Implementations of member functions of student record array class should be dependent upon member functions of individual student record class. You may insert more member functions to individual student record class whenever necessary.

You can assume that all scores are integers from 0 to 100. Output of the program should be printed on sreen. Athletes’ names ID numbers, class, ranks, and, letter grades are to be printed twice, the first time in alphabetical order by last name, with "A" students first, "B" students second, and so forth. In cases when the last names of more than one students are the same, sort the student records with the same last name in alphabetical order by first name. The second time they are to be printed in alphabetical order by last name, with freshman students first, sophomore students second, and so forth. Also sort student records by first names in cases when last names are the same. (Note the difference from Project 1.) Note that the students’ names are printed out in the format of "Lastname, Firstname", e.g., "Zitt, Kevin"; the column of student ID numbers should be aligned three spaces beyond the maximum name length, the column of class ranks should be aligned three spaces beyond the column of student IDs, and the column of grades should be aligned three spaces beyond the column of class ranks.

A sample implementation file of the class member functions and a main function is written in file proj3_prototype.cpp. In the main function, there is an outline of the suggested steps to do the reporting job.

On the due date (check the schedule), turn in a print-out of the program source code and a diskette containing the header (.h) file, source code (.cpp file), and the I/O files.
