What are some common iterator algorithms in C++?

In C++, common iterator algorithms include std::find, std::sort, and std::copy. They help manipulate collections.

Can you explain how std::sort works with iterators?

Sure! std::sort takes two iterators as parameters, defining the range to sort. It rearranges the elements in that range.

What is the difference between std::begin and std::end?

std::begin returns an iterator to the first element, while std::end returns an iterator to one past the last element of a container.

Are there any performance considerations when using these algorithms?

Yes, performance can vary based on the algorithm and the container type. For example, std::sort has a time complexity of O(n log n), which is efficient for most cases.
