What are the main differences between C++20 and C++17?
C++20 introduces several new features like concepts, ranges, and coroutines, enhancing type safety and performance.
Can you explain what concepts are?
Concepts are a way to specify template requirements, allowing for more readable and maintainable code by constraining types.
What are ranges in C++20?
Ranges provide a new way to work with sequences of elements, making it easier to manipulate collections with a more expressive syntax.
Are there any performance improvements in C++20?
Yes, C++20 includes optimizations in the standard library and features like coroutines that can improve performance in asynchronous programming.
How does C++20 affect existing C++17 code?
C++20 is largely backward compatible, but some deprecated features from C++17 may be removed, so testing is recommended.
