Can you explain the differences between the various iterators in C++14's standard library?
Sure! C++14 offers several types of iterators: input, output, forward, bidirectional, and random access. Each serves different purposes.
What are the main characteristics of random access iterators?
Random access iterators allow you to access elements in any order, similar to pointers. They support arithmetic operations and can be incremented or decremented.
How do they compare to bidirectional iterators?
Bidirectional iterators can only move forward and backward one element at a time, while random access iterators can jump to any position directly.
Can you give an example of when to use each type of iterator?
Certainly! Use input iterators for reading data, output iterators for writing, forward iterators for single-pass algorithms, bidirectional for linked lists, and random access for arrays or vectors.
