Hi all
I agree with Jan, but ...
A clue to the second part of your problems might be to use a defined type as
the object pointed to.
( I don't think that would qualify as an array - for the purposes of obeying
the rules imposed by the lecturer. )

You might find some clues in an unpublished "book" I wrote a few years ago,
available in PDF form from Walt Brainerd for a few dollars.

Your problem appears to be a "multiply linked list" or "threaded list."
There is a brief discussion on P 118.
But you still have to figure out the rest of it yourself.

Subject: Pointer program
I am having great difficulty in writing this program. I have been able to
read the data into a program but I do not know how to link all of these
together using pointers. I also cannot think of a way to appoint the class
ranks or a way to assign the letter grades. Any help would be greatly
appreciated.
1. Read this input file "data.txt" into a data structure you defined; (It
must be of pointers, but not array. An easy way of doing this is to form a
chain like that on page 602 of the textbook.)
2. According to the student's grade, you will need to define his or her
rank among all;
3. The input file is initially of random order, you will need to reorder
the input file three times by the alphabet order of the student's name, ID
number, and rank, and output the reordered information to the output
file "name.txt", "id.txt", "rank.txt" respectively; (Each output file will
still consist of all the information of the students: name, ID, grade and
rank, but not only a specific item)
4. For the student whose grade is less than 60, mark him or her failing in
the test, "F"; for the student whose grade is between 60 to 80,
mark "P" ; for the student whose grade is above 80, mark "E";
5. Output the following information to a file named "grade.txt". It should
consist of three items: name, ID, and letter grade.
