What this C++ language fundamentals question tests

This is an easy C++ question designed to assess your understanding of core language behavior and how the compiler handles specific code patterns. It rewards close reading of syntax and familiarity with standard library semantics over algorithmic problem-solving.

To answer questions like this, you need to trace through the code mentally, understand how each construct behaves, and predict the program's output—or recognize when it may fail to compile or run. Quant firms use these questions early in screening to filter for candidates with solid C++ foundations before moving to more complex algorithm and systems problems.

• Compiler behavior and error detection
• Program execution flow and output prediction
