Thread: Passing and using a Array nested Structure

This project requires me to take an input file and scan its information into an nested array structure. So far I have finally been able to fill the nested structure after converting the file's strings to the appropriate types. Now however, I don't understand how to pass the nested structure, STUDENT for use in other functions. Placing the structure in the header as a global declaration is out of the question for this project. Any help is appreciated.

Code:

   This program requires three command arguments: The text file name, 
   the number of entries to be scanned from the input file, and the input 
   file name.  The program will scan the input file's entries into a 
   structured array and sort the arrays.  It will also print the unsorted and
   sorted arrays.  Lasltly, it will allow the user to run queries for certain
   entries using the SSN.
