How do you clear a stringstream variable?

Question

I\'ve tried several things already,

std::stringstream m;
m.empty();
m.clear();

both of which don\'t work.

Answer 1

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.
