How do I adapt legacy iterators to ranges?

In C++, adapting legacy iterators to ranges can significantly enhance code readability and maintainability. By integrating these iterators into the ranges framework, you can take advantage of modern C++ features while still leveraging the benefits of existing iterator-based code.

Example of Adapting Legacy Iterators to Ranges


        // Legacy iterator example
        std::vector legacyVec = {1, 2, 3, 4, 5};

        // Adapting legacy iterators to a range
        auto range = ranges::views::iota(legacyVec.begin(), legacyVec.end());

        // Using the adapted range
        for (const auto& val : range) {
            std::cout << val << " ";
        }
