What this C++ positional-reasoning question tests

This is an easy code-reading question that asks you to trace through a C++ program and predict its output. It is designed to assess whether you understand how C++ language semantics—operator precedence, variable scope, control flow, and standard library behaviour—work in practice.

Questions of this type appear frequently in technical interviews because they separate candidates who read code carefully from those who gloss over details. The skill being tested is not algorithmic problem-solving, but rather precise language knowledge and the ability to mentally execute code without running it. This becomes valuable in fast-paced trading and systems environments where understanding exactly what code does—before it ships—is critical.

• Operator precedence and associativity
• Variable scoping and lifetime
• Control-flow logic (loops, conditionals)
• Standard library function behaviour
