What are the differences between iterators and pointers in C++11?

What are the differences between iterators and pointers in C++11?

In C++11, iterators are abstract representations of a position in a container, while pointers are direct memory addresses.

Can you explain how iterators provide more flexibility than pointers?

Sure! Iterators can work with different types of containers and provide a uniform interface, while pointers are limited to arrays.

Are there any performance differences between using iterators and pointers?

Generally, iterators may have a slight overhead due to abstraction, but they often optimize access patterns for specific containers.

When should I prefer using iterators over pointers?

You should prefer iterators when working with STL containers, as they enhance code readability and maintainability.
