The header <iomanip> is part of the Input/output library of the C++ Standard Library. It defines the manipulator functions resetiosflags(), setiosflags(), setbase(), setfill(), setprecision(), and setw(). These functions may be conveniently used by C++ programs to affect the state of iostream objects.


namespace std {
    //  Types  T1,  T2, ... are unspecified 
    //  implementation types
    T1 resetiosflags(ios_base::fmtflags mask);
    T2 setiosflags(ios_base::fmtflags mask);
    T3 setbase(int base);
    template<charT> T4 setfill(charT c);
    T5 setprecision(int n);
    T6 setw(int n);
