    Manipulator are special functions that are used to change certain characteristics of the input and output. They change the format flags and values for a stream.
    Following are the standard manipulators:
    endl
    hex, dec, oct
    setbase
    setw
    setfill
    setprecision
    ends
    you can also create your own manipulators. The syntax for creating user defined manipulators is defined as follows:
    ostream & manipulator_name(ostream & ostrObj)
    {
    set of statements;
    return ostrObj;
    }

    In the above question base and bin are not the manipulators.
