iterators. Basic introduction (from Network): Iterators are an abstract concept. Ability to traverse some/all elements within a container. Each iterator contains the address of the element.It can combine abstract containers with generic algorithms. Approximate principle: 1)the Iterator object contains the address of the element within the container. 2) through the design, the element operation is unified. Personal Understanding: 1) The concept of iter
