What are the differences between C++ iterators?
C++ iterators are categorized into several types: input, output, forward, bidirectional, and random access. Each type has different capabilities.
Can you explain the capabilities of random access iterators?
Random access iterators allow you to access any element in a sequence in constant time. They support operations like addition and subtraction.
How do they compare to bidirectional iterators?
Bidirectional iterators can only move forward and backward through a sequence, while random access iterators can jump to any position.
Which one should I use for a linked list?
For a linked list, bidirectional iterators are more suitable since they allow traversal in both directions without the need for random access.
