A Helper for Initialization

What this C++ initialization question tests

This is an easy question that focuses on understanding a specific C++ language feature and its behavioral consequences. It's the kind of question used to filter for candidates who have hands-on familiarity with modern C++ rather than just textbook knowledge.

The question asks you to read code closely and predict what actually happens when it runs. To answer correctly, you need to understand the initialization mechanism at play, how it interacts with constructors and member setup, and what the compiler will and won't do automatically. Getting this right depends on knowing the precise semantics of the feature—not guessing.

• Constructor semantics and initialization order
• Compiler-generated special member functions
• Uninitialized vs. initialized state
