How do C++20 ranges compare to traditional std algorithms?

C++20 ranges provide a more expressive and concise way to work with sequences compared to traditional std algorithms. They allow for lazy evaluation and can be composed more easily.

Can you give an example of using ranges?

Sure! Instead of using std::transform, you can use ranges like this: auto result = data | views::transform([](int n) { return n * 2; });.

What are the performance implications of using ranges?

Ranges can improve performance by enabling lazy evaluation, which means computations are only performed when needed. However, the actual performance can depend on the specific use case.

Are there any limitations to using ranges?

Yes, some limitations include compatibility with older compilers and potential overhead in certain scenarios. It's essential to evaluate based on your specific needs.
