Include the iostreams standard header <iomanip> to define several manipulators that each take a single argument.

For a list of all members of this header, see <iomanip> Members.

#include <iomanip>

Each of these manipulators returns an unspecified type, called T1 through T10, that overloads both basic_istream<Elem, Tr>::operator>> and basic_ostream<Elem, Tr>::operator<<.
