What are string iterators in C++11?

String iterators in C++11 are objects that allow you to traverse the characters in a string, similar to how you would use pointers.

How do I use string iterators in my code?

You can use string iterators with the begin() and end() methods of a string. For example:

std::string str = "Hello";
for (auto it = str.begin(); it != str.end(); ++it) {
    std::cout << *it << ' ';
}

Can you explain the difference between begin() and cbegin()?

Yes! begin() returns an iterator that allows modification of the string, while cbegin() returns a constant iterator that does not allow modifications.

Are there any common pitfalls when using string iterators?

One common pitfall is dereferencing an iterator that has reached the end of the string. Always ensure your iterator is valid before dereferencing.
