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.

pair<_IntType, _IntType> std::__gen_two_uniform_ints	(	_IntType	__b0,

		_UniformRandomBitGenerator &&	__g
	)

Generate two uniformly distributed integers using a single distribution invocation.

Parameters

__b0	The upper bound for the first integer.
__b1	The upper bound for the second integer.
__g	A UniformRandomBitGenerator.

Returns: A pair (i, j) with i and j uniformly distributed over [0, __b0) and [0, __b1), respectively.

Requires: __b0 * __b1 <= __g.max() - __g.min().

Using uniform_int_distribution with a range that is very small relative to the range of the generator ends up wasting potentially expensively generated randomness, since uniform_int_distribution does not store leftover randomness between invocations.

If we know we want two integers in ranges that are sufficiently small, we can compose the ranges, use a single distribution invocation, and significantly reduce the waste.

◆ distance()

template<typename _InputIterator >

constexpr iterator_traits<_InputIterator>::difference_type std::distance	(	_InputIterator	__first,

inlineconstexpr

A generalization of pointer arithmetic.

Parameters

__first	An input iterator.
__last	An input iterator.

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.

◆ get_temporary_buffer()

template<typename _Tp >

pair<_Tp*, ptrdiff_t> std::get_temporary_buffer ( ptrdiff_t __len )

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.

◆ ws()

template<typename _CharT , typename _Traits >

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>>.
