What are some advanced techniques for using std::vector iterators in C++?

What are some advanced techniques for using std::vector iterators in C++?

You can use techniques like reverse iterators, custom comparators, and the std::copy algorithm for advanced manipulation.

Can you explain how to use reverse iterators with std::vector?

Sure! Reverse iterators allow you to traverse a vector from the end to the beginning. You can use vec.rbegin() and vec.rend().

What about using custom comparators with std::sort?

You can define a custom comparator function and pass it to std::sort to sort your vector based on specific criteria.

Are there any performance considerations I should be aware of?

Yes, using iterators can improve performance by avoiding unnecessary copies. However, be cautious with invalidation when modifying the vector.
