What this C++ language-knowledge question tests

This is an easy question that assesses your ability to read and interpret C++ code behaviour, particularly around control flow and language semantics. It's the kind of question used to verify that a candidate has solid foundational understanding of how C++ executes, rather than relying on guesswork or half-remembered syntax rules.

Questions like this reward careful attention to detail: understanding exactly what a code snippet does requires you to trace through its execution mentally, pay attention to loop conditions, and recognize any non-obvious language features at play. In interview settings, this skill matters because it separates candidates who can reason about code from those who can only write it.

• Control flow and loop semantics
• Code execution order and side effects
• Reading unfamiliar or tricky patterns
