2) Sets the field width to the given one.

Some I/O functions call width(0) before returning, see std::setw (this results in this field having effect on the next I/O function only, and not on any subsequent I/O)
The exact effects this modifier has on the input and output vary between the individual I/O functions and are described at each
operator>> overload page individually.
