Hi,
I am using a variable of type stringstream in my application. I
am adding some information in the stream. I would like to know what is
the method to make the stream empty. Thanx in advance.

you can use clear() method to make the stream empty.

use str member function.

#include <sstream>

main()
{
std::stringstream sstr;
sstr << "hello";
sstr.str("");
}

Thanks,

No, you can't. clear() clears the iostate flags. str("") makes it empty.

It sure sounds like that's what it should do, doesn't it? Too bad it
really only clears some flags. str("") is the way to reset the string.

ss.str(std::string());
