What are string iterators in C++11?

Can you explain what string iterators are in C++11?

Sure! String iterators in C++11 are used to traverse the characters in a string. They provide a way to access each character sequentially.

How do I use string iterators in my code?

You can use string iterators by creating an iterator object from a string and then using it in a loop to access each character. For example:

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

What are the advantages of using iterators over indexing?

Iterators provide a more flexible way to traverse data structures, allowing for easier manipulation and compatibility with algorithms in the STL.

Can I use string iterators with other STL containers?

Yes, string iterators can be used with other STL containers like vectors and lists, as they all support similar iterator operations.
