This is a fundamental C++ question that probes your understanding of core language semantics. It requires you to read a code snippet carefully and predict its behaviour—a skill essential in production environments where subtle bugs can be costly.
Questions of this type are common in quant interviews because they distinguish candidates who have hands-on familiarity with C++ from those who only studied it theoretically. The question rewards precise reasoning about how the language interprets the specific construct at hand, without requiring complex algorithmic thinking.
