Input-Output base classes
Header providing base classes and types for the IOStream hierarchy of classes:
Types
Class templates
- basic_ios
- Base class for streams (type-dependent components) (class template
)

Numerical base format flags ("basefield" flags):
- dec
- Use decimal base (function
)
- hex
- Use hexadecimal base (function
)

- Use octal base (function
)
Floating-point format flags ("floatfield" flags):

- Use scientific floating-point notation (function
)
Adustment format flags ("adjustfield" flags):
- internal

)
- right
- Adjust output to the right (function
)
Other functions
- iostream_category
- Return iostream category (function
)
Notice that not all standard manipulators are defined in this header. Input streams also support ws, and output streams endl, ends and flush. Streams also support an additional set of manipulators, which are parametric and defined apart in header <iomanip>. These are: setiosflags, resetiosflags, setbase, setfill, setprecision, setw
