8/25    Why are iterators "superior" or more recently popular over the
        traditional method of using  for loops and indexing?
        \_ I guess it's because you can change an array to some other data
           structure (linked-list, tree, ...) without changing the loop code.
           \_ This is a limitation of your language, not the concept of looping
        \_ They handle multithreaded use cases better.
           They hide implementation details.
           You can pass iterators around between functions and they do
           what you want witout much hassle.
        \_ Traditionally doing pointer comparisons is faster than
           dereferencing by index. (Good compilers probably will
           transform the latter for you for simple data structures like
           arrays, though.) Also, they're simply an abstraction that
           better describe what you're trying to accomplish
           (reverse_iterator) or what your needs are (const_iterator).

        The Standard C free() function only has one form and works for freeing
        both a single character and a character array.  Why are there separate
        forms in C++?  Thx.

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.

4/29    Why were C and Java designed to require "break;" statements for a
        "case" section to terminate rather than falling-through to the next
        section?  99% of the time poeple want a "case" section to terminate.
        In fact some compilers issue warning if there is no "break;" statement
        in a "case" section.  Why not just design the languages to have
        termination as the default behavior, and provide a "fallthru;"
