I am a student learning C now, I was given a homework . I spent 3 whole days on it but i still  could not figure out. this program is about to write 3-D arrays, class, student and quizz, after input 27 grades, this program should print out the average as follwing:

class1
the average for student 1 is XX
the average for student 2 is XX
the average for stident 3 is XX

class2
the average for student 1 is XX
:    :           :     2   :
:    :           :         :
class 3
:    :

The average in class 1 is XX
:     :         :    2   :
:               :    3   :

the total average  for all classes is XX

My problem is that I could not do this printout loop and average, I appreciate if you could show me how to do it without using function call.

My instructor did not teach us too much about array, and our textbook is not good for reference.

Not very kind: as an expert, you should know the difference between comments and answers, shouldn't you?

Yes , your this can be done very easily. All it requires is simple set of for loops.
My assumption is that we know the No of Students , No of Classes and No of Quizes before hand.
Your total report consists of three individual reports , which are
(1)Average of each student grouped by class
(2)Average of each class
(3)Average of all the classes
Each of the above mentioned reports requires 3 "for" loops , nested within each other.Thus you require 9 "for" loops in all.

i'm not a policeman, so take the following as just my opinion:

i do appreciate your sincerity, but please keep in mind that, first, you locked a question without an answer, second, you asked for direct contact via e-mail; both actions are violations of the expected experts' behaviour; if you keep acting this way, you will find yourself alone.
