What this C++ language-knowledge question tests

This is an easy code-reading question that checks whether you can trace execution and predict output from a C++ snippet. It's a quick diagnostic of your familiarity with the language's core semantics—the kind of question used early in interviews to establish baseline competency.

To approach problems like this, read the code carefully line by line, tracking variable states and any implicit conversions or side effects. Pay close attention to operators, scope, and control flow. Interviewers use these questions to flag candidates who may struggle with syntax or runtime behaviour before moving to harder algorithmic or design work.

• Variable scope and lifetime
• Operator precedence and associativity
• Type conversions and implicit casts
• Control flow (loops, conditionals, function calls)
