What are the basics of using iterators with std::list in C++11?

Can you explain how to use iterators with std::list in C++11?

Sure! In C++11, you can use iterators to traverse a std::list. You can obtain an iterator using the begin() and end() methods.

What are the differences between forward and reverse iterators?

Forward iterators allow you to traverse the list in one direction, while reverse iterators let you traverse it backwards.

Can you show me a simple code example?

Of course! Here's a basic example:

#include <iostream>
#include <list>

int main() {
    std::list<int> myList = {1, 2, 3, 4, 5};
    for (auto it = myList.begin(); it != myList.end(); ++it) {
        std::cout << *it << ' ';
    }
    return 0;
}

How do I modify elements while iterating?

You can modify elements by dereferencing the iterator. For example, *it = *it * 2; would double each element.
