C++17 in Detail: A Deep Dive

Problem With The Initial Example

Explore the challenges of using std string_view with temporary objects in C++17. Learn how temporary strings can lead to dangling references and understand the importance of managing string lifetimes correctly to avoid common pitfalls when working with string_view.

We'll cover the following...
