Constructing it.

What this C++ code-reading question tests

This is an easy practice question that probes your familiarity with C++ language semantics and object construction. Rather than writing code from scratch, you are asked to trace through a snippet and predict its output—a skill that matters when debugging live systems or reviewing colleagues' implementations.

Questions of this type reward careful attention to constructor behaviour, object lifetime, and how the language handles initialization. Even small details—such as the order of operations, default constructors, or scope—can change what a program prints or whether it compiles at all.

• Constructor invocation and chaining
• Object initialization syntax
• Scope and object lifetime
• Standard library output behaviour
