local_iterator end( size_type n ); (since C++11) const_local_iterator end( size_type n ) const; (since C++11) const_local_iterator cend( size_type n ) const; (since C++11) Returns an iterator to the element following the last element of the bucket with index n. . This element acts as a placeholder, attempting to access it results in undefined behavior. Parameters n - the index of the bucket to access Return value iterator to the element following the last eleme

Constructor is a special non-static member function of a class that is used to initialize objects of its class type. In the definition of a constructor of a class, member initializer list specifies the initializers for direct and virtual base subobjects and non-static data members. ( Not to be confused with std::initializer_list ). Syntax Constructors are declared using member function declarators of the following form: class-name ( parameter-list(optional) ) except-spec(optional) attr(opti
