WebMaps are associative containers that store elements formed by a combination of a key value and a mapped value, following a specific order. In a map, the key values are generally used to sort and uniquely identify the elements, while the mapped values store the content associated to this key.The types of key and mapped value may differ, and are grouped … WebThe Iterator class defines an interface for accessing the list's elements. An iterator object is responsible for keeping track of the current element; that is, it knows which elements have been traversed already. For example, a …
