//
// new2.cpp -- shows how to use the new operator to create an array
// when the program is running.  The new operator returns
// a pointer to the newly allocated memory chunk.
// This array is allocated until you use the "delete" operator
// with the array designator.
//
// This program is just a pedagogical example and is
// not very useful or well-organized
//
