A) Iterators
B) Walkers
C) Sequencers
D) Indexers

Question

Quizplus · Accepted Answer

Iterators are used to point at elements in containers and they help specify which elements in a container are to be operated on when an algorithm is called. Walkers and sequencers are not commonly used terms in C++ and indexers are not used in C++. Iterators are used to specify which elements in a container are to be operated on when an algorithm is called. They allow algorithms to access elements of the container one at a time without knowing the underlying representation of the container. This makes them more flexible than using indexers, which require knowledge of the container's underlying implementation. Walkers and sequencers are not commonly used terms in relation to containers and algorithms.
