An indexed property typically exposes a data structure that's accessed by using a subscript operator. If you use a default indexed property, you can access the data structure just by referring to the class name, but if you use a user-defined indexed property, you must to specify the property name to access the data …

WebUnordered set is an associative container that contains a set of unique objects of type Key. Search, insertion, and removal have average constant-time complexity. Internally, the elements are not sorted in any particular order, but organized into buckets. Which bucket an element is placed into depends entirely on the hash of its value. Webstd::set:: find. 1,2) Finds an element with key equivalent to key. 3,4) Finds an element with key that compares equivalent to the value x. This overload participates in overload resolution only if the qualified-id Compare::is_transparent is valid and denotes a type. It allows calling this function without constructing an ... Web*Note: All iterators in an unordered_set point to const elements. Whether the const_ member type is the same type as its non-const_ counterpart depends on the particular library implementation, but programs should not rely on them being different to overload functions: const_iterator is more generic, since iterator is always convertible to it.
