/** File "npos.cpp", by KWR for CSE250, Fall 2009.
    Illustrates actual C++ standard library usage of a "magic number".
    The actual number even has different +ve values on different CSE machines!
    But it's "int" value is always supposed to be -1, IMHO dangerously...
    Also illustrates prefixes when you don't use "using" statements.
