What are the best practices for C++20?

C++20 introduced many features. Key best practices include using concepts for type constraints, ranges for better iteration, and coroutines for asynchronous programming.

Can you explain how to use concepts in C++20?

Sure! Concepts allow you to specify template requirements. For example, you can define a concept for a type that must support addition.

What are ranges and how do they improve code readability?

Ranges provide a way to work with sequences of values more intuitively. They allow for cleaner syntax and better composition of algorithms.

How do coroutines work in C++20?

Coroutines simplify asynchronous programming by allowing functions to pause and resume execution, making code easier to read and maintain.

Are there any performance considerations with these features?

Yes, while these features improve code clarity, it's essential to understand their performance implications, especially with coroutines and ranges.
