C++17 Features

C++17 introduced several features to make programming more efficient and expressive. It added `if constexpr` for compile-time decisions, allowing the compiler to optimize code better. Structured bindings let developers unpack tuples or objects easily, improving readability. The `std::variant` and `std::optional` types offer safer ways to handle values that may or may not exist, reducing errors. Parallel algorithms enable faster data processing by automatically using multiple CPU cores. Other features include inline variables, improved template syntax, and general performance enhancements. Overall, C++17 enhances code clarity, safety, and performance, making complex programming tasks more manageable.
