trivial for me to code in C++: I can just write K&R C, it compiles and does
what I want, because C is (with minute exceptions) a subset of C++. The
reverse is not the case: C++ is a large language (compare Stroustrop's book,
which looks like the Wheeler Misner Thorn holding down RGB's desk, to
Kernighan & Ritchie; and Thompson's formal definition of B is like 3 pages).
Few people know all the formal definition of C++, much less all the standard
libraries; most work effectively with a subset. People who think of writing
to a file as piping through a stream may not be aware of "printf" or "putc",
and they need not be; unless you asked them to write someting that would
compile in ANSI C89. However, I would expect that a competent C++ programmer
could **learn** C pretty quickly.
