What this C++ code-observation question tests

This is an easy C++ question that asks you to trace through a code snippet and predict its output. It is a common warm-up in technical interviews because it quickly reveals whether a candidate understands basic language semantics and can read code carefully.

To answer correctly, you need to understand how the specific C++ constructs in the snippet behave—including scope, initialization, and the order of evaluation. Even small details matter: a misread operator or overlooked keyword can lead to the wrong answer. The question rewards methodical reasoning and attention to detail over raw problem-solving power.

• Sequence of execution
• Standard output and stream behavior
