How do string iterators work in C++17?

In C++17, string iterators allow you to traverse the characters in a string. They provide a way to access each character sequentially.

Can you show me an example of using string iterators?

Sure! Here's a simple example:

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello, World!";
    for (auto it = str.begin(); it != str.end(); ++it) {
        std::cout << *it << ' ';
    }
    return 0;
}

This code prints each character in the string.

What are the advantages of using iterators over indexing?

Iterators provide a more abstract way to traverse collections, allowing for more generic code. They can work with different types of containers, not just strings.

Are there any new features in C++17 related to strings?

Yes, C++17 introduced several features, including new string manipulation functions and improved performance for string operations.
