This is an easy question on C++ language semantics, specifically how the compiler resolves function calls when multiple overloads are present. It tests whether you can read and predict the behaviour of a concise code snippet without running it.
Questions like this appear in technical interviews to confirm that candidates have a solid grasp of C++ fundamentals—not just the ability to write code that compiles, but the ability to reason about what it actually does. The key is understanding how overload resolution rules apply in your specific context, and being able to trace through the compiler's decision process.
