/** File "stringstreamTest.cpp", by KWR for CSE250, Spring 2013.
    Illustrates a case where you might use a stringstream to convert an int
    to a string.  In C there is a function "itoa" to do this, but the
    "ostringstream" method shown here is more general---it works for any type
    for which an operator<< has been defined.  (In C++ it is traditional to
    overload << rather than write "toString()" functions like in Java.)
