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.
