In C++, how do you clear a stringstream variable?

I have a problem with a string i want to use to display in my loop.

I set it up like this in my loop:

//while {
 std::stringstream s;
 s << "Hello";

  font_surface = TTF_RenderText_Solid(font,s.str().c_str(),font_color);
  apply_surface(x,y,font_surface,screen);   

  s << "GoodBye";
  if(font_surface = TTF_RenderText_Solid(font,s.str().c_str(),font_color);
  apply_surface(bx,by,font_surface,screen);


//end loop }

The problem i have is the output first shows Hello then in the other location it has HelloGoodBye, i need to clear the content before i add Goodbye so i only see that in the second location on screen.

So how would i clear the information of Hello before I change it to Goodbye ?

If you must use a stringstream, call

s.str("");

to clear it
