Multi-Dementional array help

[Zatara7]

I have this homework assignment that I have to do but it keeps telling me that I can't pass the 2-D array by refernce. How else would I be able to make a function handle the array initialization part? Help please
here's the code:

/***************************************************************
*  Homework 11: Graded In-Class Assignment (11/3/11)
*
*  Modify the In-Class Exercise-3 (11/3/11) so that
*  1.  The information entry is handled by an appropriate function.
*      The data will be stored in a two dimensional array of type string.
*  2.  Program saves/writes the entered information in a tabular format
*      to a file, using a function.
*  3.  All functions will be called by main( ).
*
*  DUE:  11/10/2011
