A RandomNumberDistribution is a function object returning random numbers according to a probability density function p(x) or a discrete probability distribution P(xi). Requirements D is a class meeting the RandomNumberDistribution requirements. It shall also satisfy the CopyConstructible and CopyAssignable requirements. T is the associated result_type. P is the associated param_type. It shall satisfy the CopyConstructible, CopyAssignable, and EqualityComparable requirements. It also h

Defined in header <memory> template< class InputIt, class Size, class ForwardIt > ForwardIt uninitialized_copy_n( InputIt first, Size count, ForwardIt d_first); (since C++11) Copies count elements from a range beginning at first to an uninitialized memory area beginning at d_first as if by. for ( ; n > 0; ++d_first, (void) ++first, --n) ::new (static_cast<void*>(std::addressof(*d_first))) typename iterator_traits<ForwardIterator>::value_type(*f

Defined in header <type_traits> template< class > class result_of; // undefined template< class F, class... ArgTypes > class result_of<F(ArgTypes...)>; (since C++11) Deduces the return type of a function call expression at compile time. F must be a callable type, reference to function, or reference to callable type. Invoking F with ArgTypes... must be a well-formed expression (since C++11) F and all types in ArgTypes can be any complete type, array of

local_iterator begin( size_type n ); (since C++11) const_local_iterator begin( size_type n ) const; (since C++11) const_local_iterator cbegin( size_type n ) const; (since C++11) Returns an iterator to the first element of the bucket with index pos. Parameters n - the index of the bucket to access Return value Iterator to the first element. Complexity Constant. See also end(int) cend(int) returns an iterator to the end of the specified bucket (public m

Equivalent to 2) (the argument is cast to double). Parameters arg - value representing angle in radians, of a floating-point or

Defined in header <memory> constexpr std::allocator_arg_t allocator_arg = std::allocator_arg_t(); (since C++11) std::allocator_arg is a constant of type std::allocator_arg_t used to disambiguate, at call site, the overloads of the constructors and member functions of allocator-aware objects, such as std::tuple, std::function, std::promise, and std::packaged_task. See also allocator_arg_t (C++11) tag type used to select allocator-aware constructor overloads (class)
