What are the different types of iterators for std::vector in C++?

What are the different types of iterators for std::vector in C++?

In C++, std::vector supports several types of iterators: begin, end, rbegin, rend, and const_iterators.

Can you explain the difference between regular iterators and const_iterators?

Sure! Regular iterators allow modification of the elements they point to, while const_iterators do not.

What about reverse iterators? How do they work?

Reverse iterators traverse the container in reverse order, starting from the last element to the first.

Are there any specific use cases for using reverse iterators?

Yes, reverse iterators are useful when you need to process elements from the end of the container, like in algorithms that require back-to-front traversal.
