What this C++ language-knowledge question tests

This is a medium-difficulty C++ question that probes your ability to read code carefully and predict its runtime behaviour. Rather than asking you to write code, it presents a concrete snippet and asks you to trace through execution—a skill that separates candidates who understand the language deeply from those who rely on pattern matching.

Questions of this type reward attention to detail: operator precedence, scope rules, type conversions, and the order in which side effects occur. In an interview, your reasoning process matters as much as the final answer. Be prepared to walk through your logic step-by-step and to catch subtle mistakes in your initial reading.

• Operator precedence and associativity
• Variable scope and lifetime
• Type conversion and promotion
• Order of evaluation
