How do I use string iterators in C++11?

In C++11, you can use string iterators to traverse through the characters of a string. Would you like a code example?

Yes, please provide a code example.

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 will print each character in the string.

What if I want to modify the string while iterating?

You can use iterators to modify the string directly. For example:

for (auto it = str.begin(); it != str.end(); ++it) {
    if (*it == 'o') {
        *it = '0'; // Replace 'o' with '0'
    }
}

This will change 'o' to '0' in the original string.
