Reassigned Values

What this C++ language-knowledge question tests

This is a hard C++ question that probes deep familiarity with variable scope, reassignment semantics, and how the compiler resolves names in nested contexts. It requires you to trace execution carefully and understand the precise order in which declarations and assignments take effect.

Questions of this type appear in technical interviews because they separate candidates who have internalized C++'s scoping rules from those who rely on intuition. The question demands careful attention to where variables are declared, how shadowing works, and what state is active at each point of the program.

• Variable scope and lifetime
• Name shadowing and resolution
• Order of evaluation and side effects
