How do I use array iterators in C++?

In C++, you can use the std::array class along with iterators to traverse elements. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

#include <array>
#include <iostream>

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

This code initializes an array and uses an iterator to print its elements.

What if I want to modify the elements while iterating?

You can modify elements by dereferencing the iterator. Here's an example:

for (auto it = arr.begin(); it != arr.end(); ++it) {
    *it *= 2; // Double each element
}

This will modify the original array.
