Standard Stream Objects
The <iostream> header declares the eight standard stream objects. For other declarations, see http://gcc.gnu.org/onlinedocs/libstdc++/manual/io.html and the I/O forward declarations They are required by default to cooperate with the global C library's `FILE` streams, and to be available during program startup and termination. For more information, see the section of the manual linked to above.

Returns: The distance between them.

Returns n such that __first + n == __last. This requires that __last must be reachable from __first. Note that n may be negative.

For random access iterators, this uses their + and - operations and are constant time. For other iterator classes they are linear time.

noexcept

Allocates a temporary buffer.

Parameters

__len The number of objects of type Tp.

Returns: See full description.

Reinventing the wheel, but this time with prettier spokes!

This function tries to obtain storage for __len adjacent Tp objects. The objects themselves are not constructed, of course. A pair<> is returned containing the buffer s address and capacity (in the units of sizeof(_Tp)), or a pair of 0 values if no storage can be obtained. Note that the capacity obtained may be less than that requested if the memory is unavailable; you should compare len with the .second return value.

Provides the nothrow exception guarantee.

bool std::operator==	(	const queue< _Tp, _Seq > &	__x,

inline

Queue equality comparison.

Parameters

__x	A queue.
__y	A queue of the same type as __x.

Returns: True iff the size and elements of the queues are equal.

This is an equivalence relation. Complexity and semantics depend on the underlying sequence type, but the expected rules are: this relation is linear in the size of the sequences, and queues are considered equivalent if their sequences compare equal.

Array-indexing support.

Parameters

__position Index into the bitset.

Returns: A bool for a const bitset. For non-const bitsets, an instance of the reference proxy class.

Note: These operators do no range checking and throw no exceptions, as required by DR 11 to the standard.

_GLIBCXX_RESOLVE_LIB_DEFECTS Note that this implementation already resolves DR 11 (items 1 and 2), but does not do the range-checking required by that DR's resolution. -pme The DR has since been changed: range-checking is a precondition (users' responsibility), and these functions must not throw. -pme

template<size_t _Nb>

bitset<_Nb> std::operator^	(	const bitset< _Nb > &	__x,

template<typename _InputIterator , typename _OutputIterator >

_OutputIterator std::partial_sum	(	_InputIterator	__first,
		_InputIterator	__last,
		_OutputIterator	__result
	)

Return list of partial sums.

Accumulates the values in the range [first,last) using the + operator. As each successive input value is added into the total, that partial sum is written to __result. Therefore, the first value in __result is the first value of the input, the second value in __result is the sum of the first and second input values, and so on.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sum.

Returns: Iterator pointing just beyond the values written to __result.

_OutputIterator std::partial_sum	(	_InputIterator	__first,
		_InputIterator	__last,

	)

Return list of partial sums.

Accumulates the values in the range [first,last) using __binary_op. As each successive input value is added into the total, that partial sum is written to __result. Therefore, the first value in __result is the first value of the input, the second value in __result is the sum of the first and second input values, and so on.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sum.
__binary_op	Function object.

Returns: Iterator pointing just beyond the values written to __result.

basic_istream< _CharT, _Traits > & std::ws ( basic_istream< _CharT, _Traits > & __is )

Quick and easy way to eat whitespace.

This manipulator extracts whitespace characters, stopping when the next character is non-whitespace, or when the input sequence is empty. If the sequence is empty, eofbit is set in the stream, but not failbit.

The current locale is used to distinguish whitespace characters.

Example:

MyClass   mc;
std::cin >> std::ws >> mc;

will skip leading whitespace before calling operator>> on cin and your object. Note that the same effect can be achieved by creating a std::basic_istream::sentry inside your definition of operator>>.
