This is a medium-difficulty code-reading question that assesses your ability to trace execution and reason about language semantics in C++. Quant firms use questions like this to verify that candidates have solid mental models of how the language actually behaves, rather than relying on intuition or assumptions.
The question asks you to observe a code snippet and determine its result. Success requires careful attention to operator precedence, type conversions, scope rules, or memory semantics—whichever the snippet exercises. The goal is not to compile and run the code, but to reason through it step-by-step and predict the output accurately.
