    ArrayReversefunc.cpp
     
    This function is used to reverse an integer array.  For example, if the
    array is {1,2,3,4,5}, these functions will return an array like {5,4,3,2,1}.
    The user needs to pass in a pointer to the array and the size of the array,
    and the function will return a pointer to an array in the reverse order.
