Jimen> I think stringstream should behave like strstream. Comments?
They behave differently because they are different. The newer "stringstream"
class provides the capability to directly insert null characters, which the
"ends" manipulator does. When you use "stringstream", don't use "ends" to
null-terminate a string. It's not necessary.
