What this C++ language-knowledge question tests

This is a medium-difficulty question that probes your understanding of C++ operator precedence, evaluation order, and standard library behavior. It's the kind of question Nvidia and other systems-software companies ask to verify that a candidate reads code carefully and understands subtle language semantics rather than relying on guesswork.

To answer correctly, you'll need to trace through the code snippet line by line, paying close attention to how operators interact, the order in which expressions are evaluated, and what the standard library functions involved actually do. The question rewards precision: small details in C++ can change the output entirely, and interviewers use these questions to separate candidates who truly understand the language from those who only think they do.

• Operator precedence and associativity
• Order of evaluation (sequencing)
• Standard library function behavior and side effects
• Type coercion and implicit conversions
