Like to change back the fill('*') to a whitespace and change the width(10) back to default? I simply want to reset the whole thing.

Here's a link on C++ I/O.
My money is on the function "unsetf()".

You could use copyfmt() with a fresh stream object, but that's probably overkill.

Or you might use boost's IO state saver to save and then restore the stream state.

I assume you mean format flags and not stream state flags you could do:

std::ios_base::fmtflags original_flags = my_stream.flags();// ... set format flags ...my_stream.flags(original_flags); // reset them back to default.
