What this C++ language semantics question tests
This is an easy C++ question that asks you to trace through a code snippet and predict its output. It tests your working knowledge of C++ syntax and runtime behaviour—the kind of quick diagnostic question quant firms use to confirm you can read and reason about code without hesitation.
To approach this problem, work through the code line by line, tracking how values are assigned, modified, and printed. Pay close attention to the order of operations, variable scope, and any language-specific quirks that might affect the final result. These questions reward careful observation and familiarity with C++ semantics rather than deep algorithmic thinking.

- Operator precedence and evaluation order
