To reset the format state of the output stream to a previously saved state, you should save a copy of the fmtflags value (which represents the format state) by calling the flags member function before making any format changes. Then, you can restore the format state by calling the flags member function again with the saved fmtflags value as the argument. This effectively resets the format state to what it was at the time of the initial flags call.
