Describe How C++20 Ranges Can Improve the Expressiveness of Your Code

C++20 ranges simplify working with collections. They improve code expressiveness by chaining algorithms seamlessly.

Ranges provide an elegant alternative to traditional iterators. Here’s an example of using ranges:

            #include 
            std::vector vec = {1, 2, 3, 4, 5};
            auto result = vec | std::ranges::views::filter([](int i){ return i % 2 == 0; });
            

Ranges enhance readability and reduce boilerplate code. They support lazy evaluation, which optimizes performance.

Using ranges allows you to focus on what you want to do, rather than how to do it. This leads to cleaner and more efficient code.
