How do I erase elements while iterating with std::deque for embedded targets?

Erasing elements from a `std::deque` while iterating can lead to iterator invalidation issues. To safely remove elements, it's best to use the `erase` method combined with a loop that properly manages the iterator position. Below is an example that demonstrates how to do this effectively.


        #include <deque>
        #include <iostream>

        int main() {
            std::deque<int> myDeque = {1, 2, 3, 4, 5};

            for (auto it = myDeque.begin(); it != myDeque.end(); ) {
                if (*it % 2 == 0) { // Condition to remove even numbers
                    it = myDeque.erase(it); // Erase and get new iterator
                } else {
                    ++it; // Move to the next element
                }
            }

            // Output remaining elements
            for (const auto& value : myDeque) {
                std::cout << value << ' ';
            }

            return 0;
        }
