Since iterators are an abstraction of pointers, their semantics are a generalization of most of the semantics of pointers in C++. This ensures that every function template that takes iterators works as well with regular pointers.Thu, 25 Jun 2026 21:02:00 GMThttps://en.cppreference.com/cpp/header/iteratorThis header is part of the iterator library. This header is a partial freestanding header. Everything inside this header is freestanding beside stream iterators. (since C++23)Sun, 28 Jun 2026 10:15:00 GMThttps://en.cppreference.com/cpp/iterator/input_iteratorThe input_iterator concept is a refinement of input_or_output_iterator, adding the requirement that the referenced values can be read (via indirectly_readable) and the requirement that the iterator concept tag be present.Wed, 24 Jun 2026 20:14:00 GMThttps://en.cppreference.com/cpp/iterator/istream_iteratorstd::istream_iterator is a single-pass input iterator that reads successive objects of type T from the std::basic_istream object for which it was constructed, by calling the appropriate operator>>. The actual read operation is performed when the iterator is incremented, not when it is dereferenced.Fri, 26 Jun 2026 05:24:00 GMThttps://en.cppreference.com/cpp/iterator/ostream_iteratorstd::ostream_iterator is a single-pass LegacyOutputIterator that writes successive objects of type T into the std::basic_ostream object for which it was constructed, using operator<<. Optional delimiter string is written to the output stream after every write operation. The write operation is performed when the iterator (whether dereferenced or not) is assigned to. Incrementing the std ...Wed, 24 Jun 2026 17:00:00 GMThttps://en.cppreference.com/cpp/iterator/iterator_traitsstd::iterator_traits is the type trait class that provides uniform interface to the properties of LegacyIterator types. This makes it possible to implement algorithms only in terms of iterators. The template can be specialized for user-defined iterators so that the information about the iterator can be retrieved even if the type does not provide the usual typedefs.Sun, 28 Jun 2026 10:15:00 GMThttps://en.cppreference.com/cpp/iterator/iter_t1) Computes the value type of T. If std::iterator_traits<std::remove_cvref_t<T>> is not specialized, then std::iter_value_t<T> is std::indirectly_readable_traits<std ...Fri, 26 Jun 2026 16:08:00 GMThttps://en.cppreference.com/cpp/iterator/basic_const_iteratorstd::basic_const_iterator is an iterator adaptor which behaves exactly like the underlying iterator (which must be at least an LegacyInputIterator or model input_iterator), except that dereferencing converts the value returned by the underlying iterator as immutable.Thu, 25 Jun 2026 20:05:00 GMThttps://www.cppreference.com/cpp/experimental/ranges/iterator/IteratorThe Iterator concept forms the basis of the iterator concept taxonomy; every iterator satisfies the Iterator requirements. Equality preservation An expression is equality preserving if it results in equal outputs given equal inputs. The inputs to an expression consist of its operands. The outputs of an expression consist of its result and all operands modified by the expression (if any). Every ...Sun, 28 Jun 2026 20:23:00 GMT
