What are some common mistakes in C++17?

Some common mistakes in C++17 include improper use of std::optional, misunderstanding structured bindings, and misuse of constexpr.

Can you explain structured bindings and the common mistakes with them?

Structured bindings allow you to unpack tuple-like objects. A common mistake is forgetting to use the correct type, leading to compilation errors.

What about std::optional? How can it be misused?

A common misuse of std::optional is trying to dereference it without checking if it contains a value, which can lead to runtime errors.

Are there any best practices to avoid these mistakes?

Yes, always check for values in std::optional, use auto for structured bindings, and familiarize yourself with C++17 features to avoid pitfalls.
