Counting storage requests across styles

What this C++ language-knowledge question tests

This is a hard question that probes deep understanding of C++ object lifecycle, storage duration, and initialization semantics. It requires you to trace program execution carefully, accounting for how different storage classes and initialization methods interact across function scopes and program lifetime.

Questions of this type appear in technical interviews where precision matters—particularly at firms that rely on systems programming or low-latency code. They reward candidates who can reason rigorously about when objects are constructed, what their initial state is, and how scope and storage duration affect visibility and lifetime.

• Automatic, static, and dynamic storage duration
• Object initialization and default construction
• Scope and namespace resolution
• Program execution flow and function call semantics
