What this C++ language-knowledge question tests

This is a medium-difficulty question designed to probe your depth of understanding in C++ semantics and syntax. Rather than testing algorithmic thinking, it asks you to trace through a code snippet and predict its behaviour — a skill that matters in high-frequency trading environments where subtle language details can cause expensive bugs.

Questions of this type reward careful reading: you need to identify what the code actually does, not what you think it should do. This includes understanding scope rules, type conversions, operator precedence, and any language-specific quirks that might affect control flow or output. Quant shops value engineers who can reason precisely about their code's behaviour without relying on a compiler to find mistakes.

• Control flow and output behaviour
• Operator precedence and expression evaluation
