Not this, again.

What this C++ language-knowledge question tests

This is an easy C++ question that probes your understanding of operator precedence, scope, and variable shadowing. It presents a short code snippet and asks you to predict its output—a classic screening tool for catching gaps in language fundamentals before moving to algorithmic or system-design rounds.

To solve it, you need to trace through the code carefully, paying attention to how names are resolved in nested scopes and how operators bind. Even experienced programmers can trip on these questions if they rush; the value lies in demonstrating that you read code deliberately and understand the exact semantics of the language.
