Standard C++ Library : <ios> Members

Typedef

ios	Supports the ios class from the old iostream library.
streamoff	Supports internal operations.
streampos	Holds the current position of the buffer pointer or file pointer.
streamsize	Specifies the size of the stream.
wios	Supports the wios class from the old iostream library.
wstreampos	Holds the current position of the buffer pointer or file pointer.

Manipulators

boolalpha	Specifies that variables of type bool appear as true or false in the stream.
dec	Specifies that integer variables appear in base 10 notation.
fixed	Specifies that a floating-point number is displayed in fixed-decimal notation.
hex	Specifies that integer variables appear in base 16 notation.
internal	Causes a number's sign to be left justified and the number to be right justified.
left	Causes text that is not as wide as the output width to appear in the stream flush with the left margin.
noboolalpha	Specifies that variables of type bool appear as 1 or 0 in the stream.
noshowbase	Turns off indicating the notational base in which a number is displayed.
noshowpoint	Displays only the whole-number part of floating-point numbers whose fractional part is zero.
noshowpos	Causes positive numbers to not be explicitly signed.
noskipws	Cause spaces to be read by the input stream.
nounitbuf	Causes output to be buffered and processed when the buffer is full.
nouppercase	Specifies that hexadecimal digits and the exponent in scientific notation appear in lowercase.
oct	Specifies that integer variables appear in base 8 notation.
right	Causes text that is not as wide as the output width to appear in the stream flush with the right margin.
scientific	Causes floating point numbers to be displayed using scientific notation.
showbase	Indicates the notational base in which a number is displayed.
showpoint	Displays the whole-number part of a floating-point number and digits to the right of the decimal point even when the fractional part is zero.
showpos	Causes positive numbers to be explicitly signed.
skipws	Cause spaces to not be read by the input stream.
unitbuf	Causes output to be processed when the buffer is not empty.
uppercase	Specifies that hexadecimal digits and the exponent in scientific notation appear in uppercase.

Classes

basic_ios	The template class describes the storage and member functions common to both input streams (of template class basic_istream) and output streams (of template class basic_ostream) that depend on the template parameters.
fpos	The template class describes an object that can store all the information needed to restore an arbitrary file-position indicator within any stream.
ios_base	The class describes the storage and member functions common to both input and output streams that do not depend on the template parameters.
