Recent advancements in C++20 and C++23 have introduced features that significantly enhance programming capabilities. Daniel Lemire's blog post highlights several fun examples demonstrating these improvements, particularly in string formatting and error handling. The integration of the fmt library allows for elegant string formatting, enabling developers to easily print vectors and other data types with various formatting options. For instance, using `std::println`, one can print a vector centered within a specified width or in reverse order. The post also discusses the use of `std::expected` for error handling, which provides a value/error pair without relying on exceptions, making functions like division safer and more intuitive. Additionally, the blog showcases various functionalities such as printing binary representations, rotating bits, and logging with source code location details. These features not only simplify coding tasks but also improve code readability and maintainability. Lemire encourages readers to explore these new capabilities and recommends resources for further learning.
