// Filename:    Demo_Array_Pointer_Processing.cpp
// Purpose:     Demonstrate using a function for displaying 
//              the members of an array
// Comments:    Both the for loop and the function uses the
//              indirection operator for dereferencing instead
//              of the index operator
