1/14    Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
        C?  I have some overloaded functtions where one takes an integer
        parameter and the other a pointer parameter.  When I call it with
        "NULL", the compiler matches it with the integer version instead of
        the pointer version which is a problem.  Other funny effect is that
        sizeof(NULL) is different from sizeof(myPtr).  Thanks.

        In fact some compilers issue warning if there is no "break;" statement
        in a "case" section.  Why not just design the languages to have
