C Unorderedmap Example. It is a set of a Class template to use in common programming task such as in data structure and function such as in a list stack array etc. Notice that an unordered_map object makes no guarantees on which specific element is considered its first elementBut in any case the range that goes from its begin to its end covers all the elements in the container or the bucket until invalidated. This must be a class that overrides operator and calculates the hash value given an object of the key-type. If operation succeeds then methods returns iterator pointing to the element otherwise it returns an iterator pointing the mapend.
