Understanding move semantics with const objects in C++

This easy question tests your understanding of how C++ move semantics interact with const qualification. It's the kind of foundational language-knowledge question that quant trading firms use to filter for candidates with solid grasp of modern C++ fundamentals, especially in code-review and design contexts.

The question asks you to reason through what happens when you attempt to invoke move operations on an object declared const. This touches on the interplay between const-correctness, reference binding rules, and overload resolution. Getting this right shows you understand not just what move semantics are for, but the constraints the language places on when they can actually be used.

• Const qualification and its effect on binding rules
• Move constructor and move assignment overload resolution
• Implicit conversion fallbacks
