What are the differences between C++20 iterators and ranges?
An example of an AI chatbot conversation about C++20 iterators and ranges use cases.
What are the main differences between C++20 iterators and ranges?
C++20 introduced ranges as a more expressive way to work with sequences. Unlike iterators, ranges allow for more readable and concise code.
Can you give me an example of when to use ranges instead of iterators?
Sure! If you're filtering a collection, using ranges can make your code cleaner. For example, view::filter can be used directly on a range.
Are there performance differences between using iterators and ranges?
Generally, ranges can be optimized by the compiler, potentially leading to better performance. However, the actual performance can depend on the specific use case.
What are some common use cases for C++20 ranges?
Common use cases include transforming collections, filtering data, and composing operations in a more declarative style.
