What this C++ language-knowledge question tests

This is an easy question that checks your familiarity with C++ syntax and standard-library behavior. It asks you to trace through a short code snippet and predict its output—a foundational skill for any candidate writing C++ in an interview or production setting.

Questions like this probe whether you understand how common C++ constructs—such as containers, operators, and control flow—actually behave when executed. Rather than testing algorithmic insight, they verify that you can read code accurately and anticipate subtle language semantics without running a compiler.

• Container ordering and iteration
• Standard-library function behavior
• Output formatting and stream operations
